Recommended Posts

what's the percentage of driveline loss in the W's?

 

specifically my Z34.... fucking POS 4t60E...

 

 

according to G-tech, I put 141HP to the wheels

G-Tech sucks...get on a dynamometer to get a real reading, I would imagine you have more than 141hp to the wheels with the DOHC unless it's really sick :wink:

w/ good tires i think you can keep about 85% perhaps

 

Tires don't have anything to do with power loss. The power is already lost by the time it gets to the tires. A manual transmission wouldn't have as much power loss as an automatic because it is a simpler machine, so a manual will bring you down to around 15% or so. Tires aren't going to do crap for power loss.

okay... so lets say about 17.5% driveline loss, from 200HP that's 165HP at the wheels...

 

dammit.... I need traction, lol

they guy that ran the dyno at the 2002 WBG (no, I was not there) said about 18 for the manuals and 20 for the auto's.

got some new tires... did 4 runs...

 

156 + 148 + 164 + 173 / 4 = 160.25

 

200 * 0.80 = 160HP :lol:

 

woooo
