I posted this in another forum, but didn't get a response.

Okay. I want to make a set of custom emblems for my hood, but I am wanting to have an accurate # on there.

I have a stock T-56 with a Spec 3 clutch, aluminum driveshaft, stock 10-bolt with 3.73 gears, and 17" Z06 motorsport wheels.

I made 522RWHP with a 78MM intake, and no tuning. I have added a 90MM intake setup, and will tune next time. I am hoping for 550RWHP. I want to put flywheel HP numbers on the hood, so I need to calculate loss. Does anyone know what percentage HP drain that these drivetrain components have?

Thanks guys.

off topic - what's the cost and flow numbers on those heads?

on topic - why are you wanting to advertise flywheel hp?

TEA flowed them as follows:

.1000-----68.3-----55.3
.2000----143.3----124.7
.3000----225.3----178.4
.4000----270.4----233.8
.5000----307.3----259.6
.5500----319.2----266.1
.6000----324.2----270.0
.7000----330.0

Total price shipped:
$2135.65

These heads are an extremely good value. They are top-shelf! TEA is one of the best cylinder head companies in the world, and their work reflects their reputation.

I am advertising flywheel HP because that is the indutry standard, and that is the only way to make a real comparison to other vehicles on the road. Also, since it's on the hood, I want to show what kind of power is under the hood.

Not bad for the price on those heads! I gotcha on the flywheel hp now. As for the drivetrain loss, I'm not sure on the actual numbers but I would figure it would be a bit more than the ~15% stock drivetrain loss seeing as you have a lightened DS but steeper gears and probably a bit heavier wheels.

Just write on the hood that you're losing 60hp to drivetrain loss.
The rycers will understand.
