    R35 Dyno Results
    http://blogs.cobbtuning.com/?p=212

    Blue Line is torque (peaked at 416 ft-lbs)
    Red Line is HP (peaked at 419 HP)
    Green is Boost (peaked at 13.8 psi)
    Gray Line is A/F Ratio (dipped down to around 10.5:1)

    this was using...
    A 50/50 mix of 91 octane and 100 octane was used, which isn’t too different in octane rating from the fuel normally used in Japan.
     
  2. Interesting stuff. Cheers.
     
  3. i thought they were supposed to dyno at like 480?

    US 93= Japan's highest regularly availible fuel in japan, just figured differently.
     
  5. It's measuring at the wheels plus the cars not broken in.
     
  6. 480hp at the wheels? That would be like 1920hp. <A BORDER="0" HREF="http://www.supercars.net/PitLane?displayFAQ=y"><IMG BORDER="0" SRC="pitlane/emoticons/amazed.gif"></A>
     
  7. i know. He claimed a previous dyno had proven they dynoed at 480 at the wheels. Breaking a car in doesnt gain 80 hp.
     
  8. Did you read the links?


    "c) We’re at ~4000 ft altitude here in SLC. Thinner air, less power. Even with turbos. Hard to directly compare NA to Turbo but a brand new stock Z06 puts down 405 HP to the wheels on our dyno."
     
  9. Holy shit.
