    Dyno Day

    Well, after some anticipation we have some # for everyone.

    First here is my dyno run. Stock except fluids and MTM TCU chip:

    Numbers were 377 hp and about 360 lbs. Tq. Dyno sheets won't be here for a couple days.

    Here is Pats, video tells the story.

    3 things: Kyle's car is a very healthy stock RS6. The specified and actual boost were spot on, and it posted excellent numbers.
    I had no idea that my Eurocharged tune made this much power. That's 528 ft/lbs at the wheels....Holy smokes. How could you buy anything else? Is it worth it to buy the revo so you can screw around with some knobs? Or the APR so you can yank at your blinker stalk? I'm sold.
    The third thing: On the second run for both Kyle and myself, we lost about 20-30 hp due to heat soak. By simply misting the intercoolers with a simple pump spray bottle of water before the third pull, we each gained 25-30 hp over the second run.

    The video shows 524 ft lbs. This was his first run. As Pat mentioned, we lost some hp on the second run. Then after spraying the IC's with water, The power came back. His last run was 528 ft lbs. If anyone is wondering that is equivalent to 660 at the crank assuming a 20% loss !!!!

    Some people like knob jobs and 3000 dollar reflashes that dont make power. Some people like junk stock intercoolers that leak like the BP oil well.

    I think these cars are closer to +25% driveline loss, if not higher...What do these cars make "stock"? 300-320 awhp depending on dyno? At 450crank hp thats 320/450=.71111. That's 29% there?

    Mine came in at 377hp stock at the wheels. So at 450 hp crank, this would be a 16% loss. IMHO I do not think this is accurate. There should be more drivetrain loss. Guessing is all we can do as far as what the drivetrain loss really is.

    A different Dyno? Maybe.

    But do we really know if Audi "underrated" the power a bit. Could be.

    Plus, using 25% means that Pat is closer to 700 ft/lbs.
    "I think these cars are closer to +25% driveline loss"

    Nevertheless, the Eurcharged tune Pat has is incredible.

    Interesting information, thank you for sharing!

    FWIW: Mustang tells us to allow for 28% driveline loss in Quattro, Automatic Audi pulls.

    Every dyno has different traits. Word on the street is Dynojet reads higher than Mustang. That is fine.

    The solid data speaks for itself. The stock car in excellent tune put down a number. The modified car in excellent tune put down a bigger number. The combination of the two plus the VagCom data logs with each car on the dyno is the whipped cream on top. Now we can look over the logs and determine where and how the extra power was made.

    Its too bad JRS could not make to the dyno because his car has a different upgrade path and should have been a good comparison to the other two cars. And the Wagner intercoolers could have been tested out to determine efficiency with VagCom data logs on IATemps.

    Next time.

    Other than the Eisenmann exhaust, that's it for engine mods.

    Yes you missed two biggies

    Stock intercoolers
    BND Aces

    :-)

    Aces rocks! Its now touching the 100s here in AZ and my car is still screaming. RS600 venting in the pan and Aces in the tank and the car just plain nuts. Drove it today and I was a very happy camper. I just need to finish up that intercooler sprayer package and look out idjuits

    fwiw my car stock put down something like 335 awhp stock, and 350 tq. with my oct tune/milltek full exhaust with race cats it put down a peak of 370/420.

    the area under the curve gain was very big, so the #'s don't tell the whole story.

    but stock for stock.. although there is definitely going to be car to car variability... it's hard to know what to think if a totally stock one makes 400awhp etc.. dyno vs. temps vs. fuel?

    and i haven't really followed the eurotune threads too much, as i'm already tuned...

    what's involved with the reflash? Since i'm already paid up on the OCT, if i don't like my eurotune i can always reflash OCT.

    I will meet you 1/2 way and we just race it off.

    You cant push the go juice. Motor to motor.

    If your OCT wins...you saved 600 bucks. Eurocharge is a reflash only.

    Really the drivetrains have only about 18 to 20% loss. Believe it or not they are pretty efficient. I have never seen one Dynoed with less than 22% loss and that was totally stock with heavy chrome 20" wheels (stupid) and about 96 degrees ambient temp. 03 RS6 450, RS6+ 480....

    Yes. All the RS6's I've seen dyno'd were on a Mustang and have been between 300-330awhp.
