Interesting that the laptimes are similar to Suzuka. I'm not very familiar with the Bathurst track so need to watch those videos.

[Dresden]

fast lap was pretty sweet.

Mines Spec-V GTR

http://www.4wheelsnews.com/preview-n...pecv-by-mines/

Mine’s, the top Japanese GT-R tuning firm, is currently focusing on the GT-R SpecV although it does not claim ownership of the black performance car. Mine’s is presently in the process of research on the most expensive Japanese vehicle on the market (worth 15,750,000 Yen or $175,000) which premiered last February 2 in Japan.

The remarkable stock GT-R has received heavy improvements to transform it into a SpecV. It comes with Ray aluminum wheels in black finish with unique Bridgestone high-grip non-flat rubber. The engine, a VR38DETT, has been tuned although the total power yield is the same. The SpecV comes with a High Geared Boost which boosts the pressure on the turbocharger in real time increasing torque up to 608Nm (62.0kgm). This aims at heightening mid to high range torque. Other features include a titanium exhaust system that optimizes exhaust resitance plust a fin and rear air diffuser to improve cooling. Vehicle weight was effectively lowered by 60kg (132lbs) by getting rid of all unnecessary amenities like the rear seats and others. This performance vehicle is fit for the tracks and not for the road. Outside everything is in carbon. What Mine’s will do to a car based on the SpecV is anybody’s guess, but it’s pretty exciting just waiting for it to come to pass.

I havent read the entire thread, but which members are actually shopping to purchase a GTR? The few dealerships ive spoken with are really being ridiculous about the price, hence im considering buying one with low miles (>1000). Ive seen a few good deals on ebay, but dropping 74k on ebay just isnt in the cards lol.

Edit: Im not up to date on the problems with the tranny, but is Nissan repairing this or are owners getting shafted on the bill. Also, is this tranny issue addressed in the upcoming 2010 GTR?

[jimmyP]

The trans problem should be fixed with the new LC update, all 09 cars get the update for free so you can launch all day now with VDC on also 2010 cars all come this way now. The car has gone faster with the new update check out Edmonds.com for more info.

Samurai Speed's Transmission Dissected

We've been very busy with the renovations on our new shop that we hadn't had a chance to dig into our broken tranny. That and the fact that we ran into some problems with pulling the gears apart -- we had to send it out to someone to have it done as the gears are pressed on super tight.

Well, we finally were able to get it apart and take a closer look at it. Big thanks to Eddie, our head mechanic, for busting his butt on it.

Here are some photos where you can see the damage to the first gear itself as well as the gear shaft...











After closely examining the broken first gear, and seeing a pattern of hairline cracks in different places throughout the gear, it is our conclusion that the damage to the gear is most likely NOT from wheel hop. (Hence the reason there was no wheel hop on the launch that it broke.) It appears as if the residual damage is simply from LAUNCH CONTROL ITSELF.

The LC process seems to put so much pressure on the gear that over time it produces fractures and then ultimately the teeth break off. Using launch control then becomes like RUSSIAN ROULETTE... if the gear comes to a stop where you are about to perform another launch, and that position on the gears does not contain an existing fracture, then you'll most likely not experience breakage from that actual launch; however, that new launch could certainly produce new fractures of the gear near that position where most of the stress was placed from LC.

Remember how my car had over 100 launches on it? And yet others broke from 20 or less launches? It's literally called LUCK. It my case, the gears happened to not come to rest (before another LC was going to be performed) where previous fractures had occurred. So the pressure that new LC would put on the gears was being done just as if the car had never been launched before. It was literally like playing Russian Roulette. If the gear came to a stop directly on top of an existing fracture and you launched again, your odds were very high that the gear would break on that launch. Not always the case as some spots possibly took multiple launches with existing fractures, but it certainly appears that if you happened to stop the car with that pre-fractured area of the gear teeth lining up on the gear shaft and you went to launch the car that it was most likely causing the breakage.

So it certainly appears that it's not just wheel hop causing the damage and that it's the pure force of launch control itself that was putting the stress on whatever teeth were lined up on the shaft at the moment of impact. Bottom line... the gear materials don't seem to be strong enough to withstand the force of launch control.

We're now in the process of having a stronger first gear and shaft made... not only of stronger materials but also cryo-treated. Once we get this made my goal is to take the car out and do 100 LAUNCHES IN A ROW on the same day. We'll have to let the car cool down with temps, etc. when needed, but the goal is to bang the hell out of it to really test it. Then we'll open the tranny back up and analyze the condition of that 1st gear and shaft.

We'll post more news as it becomes available.

100 launches in a day is a bit excessive. But if it holds up, that's great.

[dacman]

No kidding, single disk clutches are gone after 30 launches. Multi-disk clutches last a bit longer, say a hundred or so.

I'd say it would be a bit silly to upgrade the gearset, and to then put it back together with the stock clutches, only to have to pull it apart again, to replace them.

Looks like the SpecV is slower than the standard GTR at Tsukuba but the 2009 GTR is pretty rapid. This was a same day, same driver test at Tsukuba.

MY08 GT-R (JDM - December 2007 delivery): 1:01.888
MY09 GT-R (JDM): 1:01.343
SpecV GT-R: 1:02.4

Yup, I knew the big increase in price wasn't worth it. Although something just doesn't seem right for a car to have more power, better brakes, less weight etc. and to be slower. I guess the GTR does not defy physics afterall

My guess is either the 2 base GTR's are better than average GTR's or the SpecV was below average for a SpecV.

[mc_hammer]

Or the suspension wasn't as versatile/well-developed and CCBs don't work very well over short stints.

Hey guys, Megan Racing's management wanted us to spread the word that their testing of their coilovers on their test GT-R is complete. We will be the EXCLUSIVE dealer of these when they are released in a month, and are running a special of only $999 shipped, which is far below any other coilover out there!

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.

We will be getting a set to install and do a write-up on, and hope to do some testing versus the stock coilovers at either Talladege GPR or Road Atlanta in the near future.

[Steve Theodore]

Spec V has been proven to be quicker on longer tracks, relative to the base spec. Perhaps it's something about the track (Tsukuba) or the conditions that day that prevented a more competitive time? We can speculate until we're blue in the face, but it will be fun to see what the Spec V does on other tracks like Suzuka, etc.

INCORRECT. The time has yet to be confirmed and these times were on DIFFERENT DAYS with DIFFERENT DRIVERS.

Do you honestly think the Spec V is going to be slower? Its the exact same car but better.

Hopefully Megan's are not exploding anymore.

Either way i don't think any R35 owner wants to run chinese made coilovers over something Nissan tried so hard to engineer right.

[punch]

Yeah really. Megan Racing on a GTR. It's laughable.

Maybe the owners that thought 22" rims on a GTR were a good idea will want to run them?

It's possible that I'm passing on bad information in that case. Nevertheless the 2009 GTR time is amazing. Here's the original post:

http://www.gtr.co.uk/forum/113047-ni...t-results.html

The Japanese press have finally got their hands on the production Nissan GT-R SpecV this week and they’re wasting no time in putting it through it’s paces on the circuit. Today we’ve learned that Best Motoring have had Tsukuba Circuit to themselves for the day as well as a SpecV GT-R. Put that together with tame racing driver Keiichi Tsuchiya and good weather and you’re set for an interesting afternoon.

Sources close to Best Motoring have given us the SpecV’s time and instead of keeping you all waiting like we love to do we’ll give it to you straight… 1:02.4.

Unfortunately this means it’s slower than both the 2009 and 2008 base GT-R at the same circuit in similar conditions. Here’s how the SpecV stacks up against the most recent base model GT-R taken from the current issue of Japanese mag Car Top:

MY08 GT-R (JDM - December 2007 delivery): 1:01.888
MY09 GT-R (JDM): 1:01.343
SpecV GT-R: 1:02.4
On a short circuit like Tsukuba the times should be close together but the SpecV should be in front, it should be 1:00 flat. So this begs the question: What’s the deal? We’re really hanging out for the April edition of Best Motoring DVD to find out more.
