Hey there,

I know that the literature states that a stock 04 S/C GTP has 260hp and I am assuming that is at the crank. How much actual hp is at the wheels on a stock S/C GTP?

Thanks!

After driveline loss, approximated at 20%, a stock L32 should lay down between 205 & 215HP.

Until you make your car really really fun and start modding.

Those numbers are about right, Will. Is on the high end of the tolerance I figure, so nice numbers.

Don't forget that over the years some of the ponies will leave the stable espcially if the car's been abused.

If you fully know what you're doing. If you take care of your engine (regular oil changes, safely mod with little to no kr) you can push past a lot of v8's. Just do your research and take care of your engine.
