Time Lapse Engine Build : Cobb Time Attack R35

ADVERTISEMENTS

Cobb Tuning has been competing in the Redline Time Attack with their R35 this year. The car runs in the Modified class and won the modified class, and overall at New Jersey Motorsports park, after losing an engine at Buttonwillow.  After Buttonwillow the team replaced the expired engine with one from a wrecked street car.  They had a few issues at New Jersey, but not enough for them not to take the overall win.

At Las Vegas some issues from the wrecked street car engine reared their head, and the team decided to build the engine.  The next round of Redline Time Attack is at Auto Club Speedway in Fontana, Ca this weekend, May 29-30th.

The Redline Time Attack is going to be covered Live Streaming in a partnership with the guys at Owle. I was browsing some sites yesterday, and saw this neat add on for the iPhone. Its a better lens/ holding system for the iPhone that will give you good quality video for only $129. They will have up to a dozen cameras streaming at the same time, with some of them inside or on cars. John Naderi and Kerryann De La Cruz will also be in the paddock doing live interviews.

Switzer P800 Nissan GTR vs Koenigsegg CCR x 2 Races

ADVERTISEMENTS

Koenigsegg might be a name you have never heard of. They are a semi- obscure Swedish super car manufacturer that tried to purchase Saab in 2009 from General Motors.  However, they never carried though with the sale.
The CCR was produced from 2004-2006 by Koenigsegg, so this car is pretty rare. It was also listed as the “fastest production car” in the world, in 2005 to 2006 when the Bugatti Veyron beat it.  Power is listed as 896 hp, and weight is listed as 1180 kg (2601 lbs) dry giving it an impressive power to weight ratio.

On February 28, 2005, at 12.08 local time, the Koenigsegg CCR broke the production road car speed record, achieving a new official top speed of 387.37 km/h (240.7 mph) at hoi Italy's Nardo Prototipo proving ground. A team of five Koenigsegg engineers and mechanics together with founder Christian von Koenigsegg ran a technically standard CCR, driven by famous supercar test driver and veteran record breaker Loris Bicocchi.

In this video, from 2nd gear, the CCR clearly walks away from the Nissan GT-R at higher speeds. From the 1st gear roll, the CCR spins the tires , and then again in 2nd gear, giving the Nissan GT-R enough space to keep it out in front.  With nearly 900 hp, and more than 1000 lbs lighter than a GT-R, its suprising the CCR didn’t pull harder on the Switzer P800 GT-R.   I was just reading about a Switzer GTR 1RK 1000+hp GT-R on Nagtroc today.  Heres a sneak peak video.

The following is some information on the stock and aftermarket turbos available for the Nissan Skyline GT-R , and Nissan GT-R. R32, R33, R34, R35 as they are often referred, being the chassis codes.
 

 

 

 

 

 

 

 

R32, R33, R34

Above about 1.1 bar the stock RB26 turbos have a tendency to break the exhaust wheel off. People have gone low 12's, high 11's on the stock turbos, but not for long. Stock peak boost R32 is about 0.8 , R33 0.9, R34 1.0.

 

 

 

 

 

 

 

The exhaust manifold on the left side of the picture is a stock R32,R33, R34 piece. On the right is a modified N1 exhaust manifold from a Nismo built Super Taikyu car. You can see bracing between the manifold flanges, and the larger hole for the turbo “foot”.

 

 R35 GT-R

Uses an IHI turbo, with an integrated exhaust manifold.
