    Dyno Results

    9/19/2009, 92 degrees, 39% humidity

    422.58 hp

    How much do i lose to the wheels to figure out my bhp? 20%? 25%? 30%? I tried to use the search tool but there seems to be a bunch of different answers

    Nice graph

    You could search for some other dyno numbers to compare.

    The %loss will be hard to determine as does dyno numbers between different dynos.

    Can you tweek your tune? low rpm peak torque just a tad lean which could explain the slight dip in mid range. Could be worth looking into.

    i was searching through posts, and the average seemed to be around 25% is what's lost with all wheel drive.

    like dave said though.. i guess every dyno is different

    On a Mustang Dyno and Automatic trans, 25% is what we figure as well.

    I said "about 100hp" which is about 25% (give or take 10 or so hp dependant on what your running)........

    280kw on wheels is solid , i managed 310kw on the wheels with 690nm torque after a few runs went down to 280kw's on the wheels.( to much heat)
    boost was at 1.3 bars with 98 unleaded racing fuel.

    i'm working on 360-kw's on the wheels by end of year

    360kw=473hp. At the wheels will take a LOT of doing. Big turbo's bigger injectors etc etc.

    Good luck

    IIRC, AWE uses a factor of about 1.28 on their Mustang Dyno for the GIAC tune for the RS6, so very close to 25%. Like everybody says, diff dynos vary. I usually just plug this # in when given an AWD car and WHP, since this number will not leave my head now.

    Fonzie, nice numbers, btw. Was that on pump gas?

    I have heard stock US 2003 RS6s make about 350 AWHP. I would believe the 100 RWHP loss is accurate.

    My Tahoe looses 25% with 2 wheel drive. It has a old tech drive line though. :cool2:
