Beyond The Dyno » Option Magazine - R35 GT-R Exhaust Test

You should go and pick up a copy of the February 2008 copy of Option Magazine. Hiro the editor in chief just sent me a copy because there’s a feature of Cosworth in it. Aside from the fact that there’s a bitchin feature of Cosworth in it (and a picture of yours truly with a stupid ass smile), the main focus of this issue is the R35 GT-R. There’s also a R35 GT-R catback exhaust test in it where some shop fabricated a titanium catback exhaust and the car made 507.9ps (500.95hp) at the flywheel. Granted, this test was conducted on a Dynapack so it probably read 5% or higher than any other dyno, but the gain of 22ps is for real. If you can’t do the math, that’s 485ps from the factory which is pretty god damn buff already considering the car is rated at 480hp at the flywheel. The boost went up by 0.1kg/cm^2 (1.42psi) due to the reduced backpressure, but this also tells you that the car has some serious potential from the factory. By looking at this exhaust I can guarantee you that it’s louder than hell so I wouldn’t expect a 22ps gain on a production catback exhaust though. Excuse the shitty scans…

looks really good but looks very expensive to tune.just look how hard that exhaust looks to make

Agree. The price will be expensive.

500hp at the flywheel? i thought there was another dyno floating around here showing a standard gtr pushing around 480 at the hubs/wheels. which would equate to about 550ish hp at the crank, if you were to use 15% for drivetrain loss. can anyone clear this up or was that dyno a bit on the wild side? Eitherway that exhaust looks mighty fine!

There was one run at a Super Autobacs location, but it's too hard to know what condition it was run under so the results might not mean much, but yeah it did record more than this specific run........again it's all about how it was setup/run.
