Dyno run

[AirMarcus]

With 418 hp at the rear wheels what would you estimate the hp is at the flywheel?

[nhraformula]

add 15% and youll be in the general flywheel range

est. flywheel hp: 480hp

Thanks, I'll have to work on it some more!

A4 or M6? If I remember correctly it about %15 loss on an A4 and about 13% on a M6. But then again they are still rough estimates.

[AirMarcus]

I've got a M6. What do you think with an older vette with a 4-speed?

[craz1469]

i thought it was 17%-19% for a m6 and 21%-23% for an auto

[Killer_bluebird]

I don't think so but then it also depends on whether you have a stock rear or a heavy 9" or 12 bolt. As far as the "older vette with a 4-speed" it is hard to say. The % of drive line loss changes from car to car and manufacturers. I remember reading an article that compare a chevy setup versus ford and the ford experience a higher amount of drive line loss. But unless you take an engine dyno it then dyno it again installed it is all guessing.

Thanks for the info. Strange 12 bolt 4.10 gears Yeehaa!

also if a person has a stall, that eats away at power.
