No, not impossible.  Godzilla just finally got a fair shot at the title with the right gloves on.

If you weren’t happy with Nissan’s re-entry into the supercar market before, right now you’re probably picking your jaw off the floor at the discovery that the German auto press feel the 2010 Nissan GT-R is nearly as fast or faster than basically any other semi-affordable supercar on the market.

I mean we’re talking the brand-spanking-new track-focused Porsche 997 GT3  Mk.2 and the Corvette ZR1 for cry-it-out-loud.   Each bested at the Contidrom circuit by the Euro-spec GT-R driven by Auto Zeitung and Autobild respectively.

And now you’ve got a lot of work ahead of you, polishing up your old conspiracy theories.  Word from the wise:  give it a rest.

 
Not clear enough? Well aren’t you the guy who wanted more than anything that Stuttgart’s shenanigans would never be discovered? That’s you, right?

Well to recap:

Yes, you’ve been wrong for well over a year now.  No, it doesn’t work the way you think it does.  Yes, it is a little embarrassing that you were so adamant about it.

I know this is going to come as a hard pill to swallow, but even some so-called ‘journalists’ were jumping at shadows. The explanation was there, you just didn’t want it to be that way.

So when should you have been paying attention?  Well remember that time you were a ‘basic physics’ student trolling an automotive forum, and one of the ‘advanced physics’ graduates attempted to enlighten you with a little tidbit that went something like:

“The GT-R puts more power to the road more often than its competitors,”
or some other variation?

Well there it is, was, and always will be;  the explanation as to why the GT-R doesn’t need to ‘cheat’ to cover ground as quickly as cars with more thrust and lest girth.

Where you went wrong was assuming the peak power matters at the same rate for all cars.  And that was never true to begin with.

Take two of our fine examples, the 485 PS GT-R and the 647 PS ZR1.  Granted, if both cars were at full power for the same number of seconds around a track, the more powerful would naturally yield a better time.  Trouble is, that doesn’t describe any track I know of, other than (don’t make me say it… ) a drag race.

You’ve likely even said it before: “to get the GT-R out of a corner, you just floor it and the AWD system points the nose in the right direction.  It instills a lot of confidence.”  At the time, you were attempting to knock the Nissan for being ‘boring’ and different.  But what you actually did was nullify your physics skills and vindicate Mizuno’s philosophy.

These images are of the South Side Performance GT-R in Dallas for the Gumball 3000! I dont want to say much but its one of the fastest cars out there including the highest rated GT-R on the market!  its taken out 700+hp porsches and kept up with the veyron’s, easily! 850hp and more updates to come after the gumball event. Notice the press release below Stating that there will be 5 Transmission packages and more power, not to mention more durability testing! Im not sure it could get better?

Edit: Added a video via Paul from the UK. he was over in dallas to see David Yu, but just missed them. Here is what paul had to say…

I left and to be honest my GTR was gathering as much attention as anything which was pretty funny… There’s a you tube link below which shows Davids car in the first minute and from chatting to some of the other drivers they are more than impressed with it! Hope this finds you well.. Paul

Thanks Paul!!!!!!

SOUTH SIDE PERFORMANCE 850 HP GTR JOINS THE GUMBALL 3000

Sioux Falls, South Dakota (April 30, 2009) South Side Performance has been taking a bit of a step back over the last few months as we have prepared and tested a wide variety of power kits ranging for 600-850 Crank Horsepower. Listening to the public, a variety of tests both on the road and the track have been performed at different power stages. After all this testing, we decided it was time for something big and challenging and the result was our entry into the Gumball 3000. The car has been outfitted with the hardware necessary to meet and exceed our 850 hp goal with our soon to be released 850 RS kit and is ready for all the journey can throw at it. Starting in Santa Monica, CA and ending in Miami, FL, this is only half of the journey to test the road worthiness of our 850 hp kit as this car will also be driven back to CA to complete a 6000 mile cross country trial. This particular car is outfitted with everything ranging from upgraded turbos, to upgraded fuel and cooling systems as well as a few parts from companies such as Aeromotions, JRZ, PasswordJDM, Stillen, HRE,HKS, and a few other partners. The car also has the ability to switch between a variety of different boost and fuel settings on the fly ranging from 570 whp all the way up and beyond the 700 whp mark. This same car has a few more tricks up its sleeve as upon its return, it will be outfitted with a few additional goodies and campaigned in the Modified AWD class of Redline Time Attack starting at the end of May. This will finish the gambit of tests and will also mark the release of 5 stages of power packages and 4 stages of transmission and drive train packages. We feel that these tests of endurance combined with our on track data will be a great indication of the durability as well as the performance that our customers can expect from their own kits. We will be posting during our trip on all aspects of the GTR’s performance and so we invite all to follow us on our trip across the country.

A look at extrapolations of the 2009 Nissan GT-R’s ‘best lap’ performance versus some of its frequent comparisons.

Using the same statistical techniques used in our earlier post, Calculating Track Times, we can take ‘best lap’ data for any number of cars and courses and predict the average distance in seconds each car will be from one-another per minute of time spent on any shared track.

Since we’re mostly concerned with the controversy surrounding Nissan’s R35 GT-R, we’ll focus on coparing it to 7 of its regular magazine competitors.   And since everyone’s favorite ‘best time’ to quote is the Nurburgring, we’ll use that as our intended projection.

Keep in mind: all of the test data so far is of the Series I R35 GT-R, known in the US as the 2009 model-year.  To my knowledge, all tests were done on the base-model’s Bridgestone rubber.   

ACR versus GT-R comparison:

Z06 versus GT-R comparison:

997 GT2  versus GT-R comparison:

ZR1 versus GT-R comparison:

997 GT3 versus GT-R  comparison:

997 GT3 RS versus GT-R comparison:

Summary of Nurburgring projections:

GT-R versus:

ACR: 7:34

Z06: 7:32

GT2: 7:32

ZR1: 7:34

GT3: 7:32

RS: 7:34

Even against the ZR1, in which the GT-R had met this benchmark only twice in timed testing outside of the ‘Ring, the formula holds true.  Showing that the drivers really did do their best with both cars on both days.   1.1 seconds per minute on the track is all the penalty you need pay to have 2 extra seats.

Projecting these onto the Nurburgring, once again shows how capable the GT-R in stock configuration ought to be.  With the right driver and conditions, a base 2009 GT-R should be putting down a low-7:30’s time on the Nordschleife.  Models fitted with optional Dunlop tires may be even faster. 

Showing relative position of some common supercars in terms of ‘best lap’ accomplishments at popular road courses.

Here’s the data (so far). This can be an evolving post as we get more ZR1 times, etc.

*Note, without the time scale, all it is showing is relative position. Distance between points per-line is equivalent to time that passes between cars completing their ‘best laps.’ i.e. seconds are not accounted for, but the positions are accurate.

I’ll catch up with this section ASAP. I just came across a mountain of data ^

Here’s how it looks benchmarked against the Corvette Z06:

Z06 versus:

Viper ACR: 0/6

Nissan GT-R: 0/9

997 GT3 RS: 1/4

997 GT3: 4/7

997 GT2: 1/4

997 Turbo: 4/7

Heres how it looks benchmarked against the Nissan GT-R:

GT-R versus:

Viper ACR: 0/6

997 GT2: 4/5 (that’ll change, the GT-R has been up against the GT2 on closer to 9 tracks. They end up being very close)

997 Turbo: 5/5

997 GT3: 6/7

997 GT3 RS: 3/4

Corvette Z06: 9/9

Here’s how it looks benchmarked against the 911 Turbo (more data points to come).

997 Turbo versus:

Viper ACR: 0/4

Nissan GT-R: 0/7

Corvette Z06: 3/7

997 GT3: 1/5

997 GT3 RS: 3/4

997 GT2: 0/3

We’re just getting warmed up. Stay tuned for updates!

*Note, I’m not working quite as hard to reference each individual time as I was for my previous post, Calculating Track Times. But each should have been quoted by a semi-legitimate source for consideration.

An effective way to predict a lap time on any high-speed road course by measuring against others.

~ by Norm McAverage

There are some out there that act confused that some people find Nissan’s R35 GT-R manufacturer laps believable. So to answer the begged question; Why is that exactly?

Well what you certainly wouldn’t want to do is take one car specification, like power-to-weight-ratio, and blow it out of proportion. That might work in drag-racing, but not for any type of track where one must consider grip, weight distribution, center of gravity, or aerodynamic properties to improve lap times.

No, a more scientific way to do it would be to extrapolate based on how well a set of cars performs elsewhere during timed laps. Let’s verify by crunching some numbers.

If we are going to benchmark the GT-R here, it would be nice if we had a control car; something that always performs well against the Nissan. Viper fans will have one more reason to smile, because today we’re going to use the ACR as the standard to which all others are judged. It has been timed at more tracks than the Corvette ZR1 and performs better than all the other entrants.

We end up with a statistically relevant set of data:

We can graph these one-dimensionally to show the difference in seconds each car came in relative to one-another. As best as run-of-the-mill graphing software can promise, it’s all to-scale – time difference in time is denoted by distance on the graph. If you’ve noticed that the hash marks are not equal, that is true. They are not intended to be. We’re interested in relative position. So the gap between the first and the last time will be set equal on each graph.

This is very telling actually. You should see a pattern developing here. If not, maybe a little further analysis is necessary. How about extrapolation? Since tracks have different lengths, we can find out how many seconds each car is falling behind the ACR for every minute of timed racing.

What this means is, for every minute spent on the track with a Viper ACR, the Nissan GT-R on average falls 1.6 seconds further behind; the 911 Turbo, 4.2 sec… the Z06, 2.7 seconds; etc.

Now, if we wanted to project how far behind the ACR each car will be on the Nurburgring, we can take the seconds they fall behind per minute, and multiply by the number of minutes the ACR took to lap the ‘Ring.

The math actually works very well. We can project how fast each car would go around the Nurburgring, whilst totally ignoring their actual reported ‘Ring times, and then compare.  

Basically there is solid evidence here that the calculation works – despite having a maximum of five data points.   The prediction for the GT-R was 4 seconds ahead of the first manufacturer claimed time, and 5 seconds behind the second claimed time, i.e. dead-center; the GT2’s projected time was 4 seconds off of Porsche’s best claimed time; and for the clincher, the Z06 time was spot-on. 

For those that need it explained, most of these cars perform very similarly relative to the ACR on other tracks as they do on the Nurburgring.

And though this should not be looked at as a GT-R versus 911 only analysis, it is clear that the GT-R consistently posts better ‘best laps’ than the Porsche 997 Turbo.

Though there is some controversy left to be had. Based on the Turbo’s performance on tracks where it has been tested against the Viper, there is no way it should be putting down a Nurburgring time close to what Porsche reports. It is just so much slower than the Viper ACR everywhere else, that 7:38 doesn’t make mathematical sense.

Of course that does not prove that, with the right driver, the Porsche could not go 15 seconds faster on the Nurburgring. Without any evidence, we are in no situation to determine that Porsche lacks a driver to make up the difference. It would be foolish to debate that ‘Ring times are 100% repeatable with all the various factors to consider.

‘Worst times’ have no statistical relevance in a comparison of ‘best times.’ A car can always be driven slower than the best time if the driver and conditions are not ideal. It may also be true that any of the cars above could achieve a better ‘best time’ if driven harder. But we are not guessing, adding a correcting factor, or manipulating for the purpose of skewing the results in any way. Those are the actual reported times here, and they are all being treated equally, at face value.

Some things to keep in mind about these times may be that while the Toshio Suzuki timed lap was on the Dunlop tires mounted to the Premium GT-R’s knurled rims, most press cars were shod with the base-model’s Bridgestone footwear. Technically, that ought to make an even stronger case for the GT-R to be able to stay within somewhat distant visual range of the Viper ACR – but still out in front of the others – on any track.

Another thing to note is that these times are all different press cars with different drivers. It’s not like it’s a single ‘ringer’ snatching up respectable times for any company. Though the GT-R is the most readily criticized for using a ‘Ring ringer, its very similar competitive prowess on other tracks does not support this conspiracy theory.

It is also clear that neither power-to-weight nor traction has been an issue for the GT-R on other paved surfaces. The GT-R posts a phenomenal time in stock configuration, repeatedly.

While it’s not proof, it does yield a rough equivalency formula:

Viper ACR > Nissan GT-R ~ Porsche GT2 > Corvette Z06 ~ 911 Turbo ~ GT3

This mental calculation has been going on in many of the GT-R acceptors’ heads for some time, brought into focus in pretty colors – if not just to annoy a few more skeptics. It makes a strong case for the ‘anywhere, anytime’ capabilities of the R35 Nissan.

While it may not be the fastest sports car in the world; if you measure what a car can do by what it has already done – statistically speaking – Nissan’s manufacturer’s claim is not farfetched.

South Side Performance the compainy with the first upgraded Turbo R35 and one of the highest horse power R35’s available has just released new Clutchs and transmission cooler for the R35 GT-R. The increasing demand for such high horse power cars and track dedicated drivers are looking for transmission solutions to combat clutch life and heat, not to mention more power.

SSP offer are currently offering clutchs for preorder now. They offer two kits, one for warn out or broken stock clutchs and the other for High power applications up to 700hp. These Have been in development since before october of last year, along with some other good treats well seen soon.

The best part of this modification is that it is a relatively easy installation that can be done at nearly any transmission shop. As a result, this is one of the simplest and most effective modifications a GTR owner can do to strengthen their transmission as a whole.

The next thing drivers are looking for is cooling. The average R35 is great but for the track it cannot take a constaint beating without proper upgrade for cooling. SSP now offer an upgraded Transmission cooler for much cooler temps for tracking the R35 GT-R. Not to mention high power applications that require addition cooling to the transmission.

During extensive testing we saw an average temperature drop of between 20-30 degrees. This is demonstrated by one of many data sets during an event at Buttonwillow Raceway in Buttonwillow, CA.

Stillen has been hard at work prepping his R35 for race competition and in the process is developing new parts for the R35 GT-R. First on the agenda is the new urethane Front lip and sideskirts of which the front lip only weighs 4lbs. Next the anti-roll bars were made, braking enhancements with new AP rotors and fedaro pads, and the new exhaust.

Kyle had this to say…

Next Month (April 4th) we hope to have KW suspension down for a a little discussion seminar on their new coil overs for the car. Then in April we’re going to have a supplier of dry carbon fiber body parts to offer a little seminar on their products. Each month we want to have a new manufacturer there so you guys can get the info. straight from them. So, if there are any companies you can think of now or any companies you have questions for let us know and we’ll get them down to our shop.

The front lip is affordable and durable because its made of urethane.

The front lip is an awesome piece and something we are very excited about. It only weighs 4 POUNDS and is constructed out of poly-urethane. We have a video of how easy it is to install it on the GT-R and it literally just snaps into place. It’s pretty impressive to see. It’s only going to be $489.00 for everything including the attachment hardware.

 

It’s urethane for maximum durability, paintable to any color or theme. It adds 2″ to the front, installs over the factory fascia/lip, and will add downforce at speed, which can help the understeer properties of the GT-R when pushed at the track. It also works in conjunction with the side skirts, also designed to increase downforce.

 

We’ll be launching the full release on the lip and side skirts here in the next day or two, in addition to the front and rear sway bar kit with bushings and adjustable endlinks, as well as the exhaust system. We’ll do a full release on all of these new items.

I cant read German and my wife is sleeping atm, so i have some scans to share of the AutoBild Magazine – sportscars at the Las Vegas Motor Speedway infield.

Some facts are this track doesnt take advantages of many turns so the GT-R will be much slower to the rest. the same test on a differnt track will net faster results in the GT-R due to its advanced AWD and cornering abilities. The rest of the cars are far more expensive than the R35 GT-R. Since the GT-R can destory most of the other compeition it has to be pitted against the best of the best, hence why its put into cars in a differnt catigory, which shows how great it is for the price.

A short rundown of what it says…

Corvette ZR1 vs. Ferrari 599 GTB Fiorano vs. Nissan GT-R vs. Porsche GT2

engine: V8 compressor vs. V12 vs. V6 bi-turbo vs. flat-6 bi-turbo
displacement: 6,162 vs. 5,999 vs. 3,799 vs. 3,600 ccm
achievement: 647 vs. 620 vs. 485 vs. 530 PS
max of torque: 819 vs. 608 vs. 588 vs. 680 Nm

0-100 km/h: 3.5 vs. 3.4 vs. 3.4 vs. 3.6 s
0-200 km/h: 10.3 vs. 10.9 vs. 12.5 vs. 10.9 s
0-250 km/h: 17.4 vs. 18.7 vs. 25.4 vs. 18.7 s
0-300 km/h: 35.5 vs. 35.6 vs. 53.3 vs. 36.0 s

1/4 mile: 11.2 cs. 11.3 vs. 11.6 vs. 11.4 s

Vmax: 323 vs. 324 vs. 314 vs. 322 km/h
track times, length 2.4 km:

0:56.86 – Corvette ZR1
0:57.49 – Porsche GT2
50:58.02 – Ferrari 599 GTB
0:58.08 – Nissan GT-R

final placement:

1st – Corvette ZR1, unbeatable at the price
2nd – Ferrari 599 GTB, high performance at a high price
3rd – Porsche GT2, brilliant, relaible, very fast, high grip, well balanced
4th – Nissan GT-R, would be a great car if there were no competition, also the price is unbeatable

Now that the Passord:JDM Rear Elevated Spoiler is now in production we got pic’s to show it off and a link to purchase! This new design keeps the center brake light, and ups the ante with quality, strenght and light weight. The wing was also made in mind to increase performance over the stock design. keeping the base aero but imporving it by adjusting the layout approx 60mm higher and 50mm farther back than stock. pitch is increased ever so slightly for just enough extra downforce without too much added drag.

With Password:JDM your investing in inovation, dedication, and research, plus everything i have just mentioned about the product above. Lightweight is a key feature but making sure that the designs incorperated are exceeding the stock deisngs and keeping them lightweight while being inovative is key. Everyone who has seen these Password:JDM products have said they are simply amazing quality, rightfully so, they are created using propriatry techniques on the same line as there lambo parts. PWJDM are very involved with the communitys they support, and thats annother key advantage to the compainy. They have released these products based on the userbase of dedicated owners of the car, which shows a great dedication to these parts being made.

Annother key advantage is the price of PWJDM peices. They are exceptional in every regards, and that means price is usually going to be very high, but Password Industries is not skimping on anything including prices which are very very good for all there products in the GT-R lineup. These are made in dry carbon weighting only 4.4lbs made 100% in the USA, have a UV clear coat and a gloss finish. The price is only $2499.99 which is easily a steal.

Daryl at J-spec connect just went into development of a few body mods for his R35 GT-R. Check out the modified side skirts and the rear defuser (rear defuser is metal right now because its a mold for the carbon fiber peice that will result from it.

which are slightly more rounded and have the indentation deleted for the door bottom rubber strip. I ended up making these skirts out of metal so they could later be used for molds. They’re slightly rounded to give it that R34 Nismo skirt look (sort of). They’ll be in production next week along with the new rear diffuser..

Hyper Power International in Cali has been dyno testing stock cars verifing the manufactures claimed horse power ratings by factoring in actual drive train losses instead of guesses. They have many cars from many different manufactures which all have exact or very close numbers to the manufactures claimed specifications. Motortrend did an articlenot so long ago testing the R35 GT-R on the hyper power dyno and achieved a very close to claimed power of the car within about 5%. Then hyper power had a fundraiser for the schoolhis children goto, for school supplies since times are rough and had a few other stock R35 GT-R’s verify the claimed horse power. Most if not all have been rated at around the 480hp rating the R35 GT-R has been rated at.

Garage Tuners have been busy at work adding extra horse power to the R35, using various methods and no one can claim max crank horse power due to the nature of most dyno’s… they are a great tool for showing the increase in horse power from parts added (by doing before and after pulls). The only dyno that’s within a very good percentage close to actual real results is the Hyper Power International dyno, of course the results have a percentage of error, but past pulls on many different cars shows very consistent results very close if not exact to the claimed manufacture specs.

Hence where we are now, how much power these cars are actually putting out when modified? The question everyone has been asking. Sp Engineering have taken up an offer to have the car dynoed at Hyper Power Internationalto find out the actual horsepower of the GT570 kit + the Cobb accessport with various octain gas.

Lets see the first tests that SP engineering have done with Cobb tuning on SP engineering’s very own dyno. The graph shows the actual horse power uncorrected at the wheels. approx 560hp give or take.

Now the same car same octain and actual crank horse power with drivetrain loss factored in the car makes approx 623hp which equates to about 10% drivetrain loss as Nissan themselves specify. Looks like pretty reliable numbers to me!

So far this is about the max power the HKS GT570 kit + Cobb accessport can put out. Meth injection and larger injectors will extract more power with the stock turbo’s but only so much before the stock turbos have to be upgraded.

Its been mentioned by Cobb tuning that the stock turbos are good for up to 21psi (1.45bar) of boost with upgraded injectors, but no further. The max the stock injectors can handle is said to be about 19psi (1.3bar). Right now testing is being done at SP engineering with upgraded injectors for even higher results.

South Side Performance, Power enterprise, AMS, and Switzer performance have all made charger upgrades to max out the stock fuel system and beyond (others will surely follow). SSP have shown 645 horsepower so far the max rated horse power (we hear it goes far higher!) from an upgraded turbo setup yet. Power enterprise are claiming 700PS with 670ps to the wheels with there 4 charger system (tho no dyno runs have been done yet). Switzer performance have stopped at 626whp for reliability, and usable track performance. AMS have yet to install there turbos for numbers but will be doing so in the next 3 or 4 weeks. The car’s potential is very high and with engine internal upgrades and transmission upgrades coming out in the next few short months the numbers are going to climb higher than these early results.

Megan Racing have created a Fully Adjustable Coilover kit for the R35 GT-R. The kit will retail at SPEED FOR SALE at the end of March. If you pre-order now they will be the Lowest price Coilover available at $999 Shipped. After the end of March the price goes back up to Regular retail price, which is also very good!

Speed For Sale will be the exclusive distributors and they will supply a writeup on installation and testing before and after versus stock coilovers at either Little Talladega or Road Atlanta in the near future. Stay tuned to Nissan GTR Club for those writeups.

Given the typical outrageous prices of most GT-R parts, some GT-R owners may be uncertain about the quality of a coilover set with such a low price. However, you can view ~200 messages from various owners at SupraForums.com regarding the high quality and performance of these coilovers by viewing THIS THREAD and also THIS THREAD. These fully adjustable coilovers are top notch quality, and we have only seen one blown shock out of about 100 sets we’ve sold for the Supra. They come with a one-year warranty, and feature 32 Levels of damper (shock) force adjustment, independent ride height adjustment, and independent spring pre-load adjustment.

The spring rates are 12kg front and 10kg rear, and have the valving inside the damper custom valved for the R35 GT-R. After much trial and error with various spring rates and damper valving, Megan Racing said their test GT-R rides nicely and handles very well, and feels very similar to a stock GT-R suspension in race mode. In the next few months, there will also be a RACE version of Megan Coilovers released with re-valved shocks and stiffer spring rates. We also offer various custom spring rates if you want something just a bit tighter or more loose.

The adjustment of the damper is as simple as can be with a built-in knob at the top of the damper mount for easy access. Simple adjustments can be made to tune to your style of driving and comfort level desired. Single-Adjustable dampers make suspension adjustments easy to tune whether you’re a professional mechanic or an automotive enthusiast with amateur mechanical skills.

The height adjustment is made easy with CNC-Machined locking perches for accuracy and smooth adjustment. You can raise your car up to factory height for OEM appearance with performance handling or you can drop your car all the way down for a formal racetrack and an aggressive stance lowering your center of gravity to gain full potential of your car’s handling capabilities.

The quality and durability of the Megan Racing Damper kits are unmatched. Made of extremely durable Steel and featuring springs that are constructed of SAE-9254 Cold-Wound Steel which are then tested over 500,000 times by compression inspection. With deformation less than 5% and high strength sophisticated surface coating, we stand by our product with our strong warranty.

Features:

• Spring Rates: 12kg Front and 10kg Rear
• 32 Levels of Adjustable Damper
• Rubber Dust Covers.
• Adjustable Ride Height
• Aggressive Spring Rates

SSP 1000RR Turbo Upgrade

South Side Performance has delivered a larger upgrade turbo than that 820RR previously released. This system is capable flowing 1000hp.

* Please Note: The 1000hp rating is for the turbines only. Clearly massive upgrading to all of the GT-R’s components are needed to support the 1000hp capacity of these turbos. The turbines will bolt right up and run on a stock motor, providing more power than stock when compared at equal boost levels.

Currently as of February 2009 there are modifications and systems in place to reach 700hp territory. In upcoming months we will release upgrades for the transmission, more fuel upgrades, more custom tuning maps and other modifications that will increase the GT-Rs capability to maximize these turbos. In due time the supporting modifications will be released to utilize the full potential of these turbos.

Currently the specifications are secret.

These new AMS turbo upgrades will be available asap and are direct bolt on replacements that can be capable of handling 800hp and above. Turn around is about one week. With oil and water fed Dual ball bearing Garret based turbo’s reliability wont be a problem.

Retails is $5500.00 and this will require sending in your factory turbo’s to be modified. If you would like to purchase these outright there will be a $4400.00 core charge added to the price.

AMS Performance will be testing these turbos in the next 3 to 4 weeks to get real world numbers and performance and reliablilty dialed in. AMS plans to start with just the upgraded turbos and a stock R35, then start bolting parts on to dial the car in. AMS have already got a full exhaust in development and should be out in a few weeks aswell.

Please email Eric at AMS performance for orders. Pictures will be available later.

The latest Episode of Best Motoring is undergoing filming and was tested earlier this week on Tsukuba Circuit. Due to the previous nights rain, lower temps and the unfriendly wet handling tires (Dunlops) the spec-v posted lower times than all the other models before it.

More testing will show that the performance is better on this race track in better conditions. The spec-v has shown to be faster on Sendai Highland raceway as we posted a video eariler - Spec V Time Attack @ Sendai Highland Raceway. The Spec-v Achived a time of 1′57″14 and the standard 09 GT-R achived a time of 1′59″51.

The results at Tsukuba are pritty good for the conditions givin comming in at 1:02.4, HOWEVER the previous times for the 09 gt-r was 1:01.34 and the 08 at 1:01.89.

In development for a March world release the new Willall transmission cooler is designed to reduce temps without complications, without issues. This design makes things simple to install and limits major problems other tuners were having with drops in preasure. Willall ensures that alot of engineering, design, and manufacturing precision goes into this product to make it all that it can be.

This design has removeable sump sections to allow for the trans magnets to be removed and cleaned when service is required.

This design Increases Rigidity, easy to maintain, and on top of its actuall function includes a natural deep  finned pan which also helps increase cooling.

Machined from a billet of Aircraft quality aluminium using 5 axis CNC technology the WR35TC sump clearly shows off its cooling fins – but before you ask this is for additional rather than primary cooling. The primary cooling core technology will be in the next installment of our release posts, and is every bit as exciting and world leading as our GR6 sump that you see here.

In the interests of durability and excellent stable temperature control we have a specifically engineered bar and plate fluid to air transmission cooler for the WR35TC project which fits in behind the standard rear mesh in the GTR rear bar cover. Mounting to factory existing points there is no cutting or modification of the GTR structure required to fit the WR35TC intercooler. It volume is excellent making stable control of the transmission temperature a reality under the most extreme driving conditions. Before anyone asks we have also included full closed loop temperature control, where WR35TC cools the gearbox only when required rather than continually which is not desirable for low temperaure conditions

The IC fits directly behind the mesh screen and is invisible, this picture just shows it off better!
