also OP needs to keep in mind that those numbers are crank HP numbers advertised... not the dyno numbers at the wheels we are posting. so the numbers given by some members are pretty close to the driveline loss estimates.

Is the higher peak torque from a small displacement engine with a turbo like the K04 really a surprise? Those are just peak numbers. The HP is so much lower because the torque is relatively short lived.

also you have to take in account where you live. down here living next to the gulf at/below sea level, we will read higher than someone in denver, as an example. that's why royal purple raceway is considered one of the faster tracks by nhra because of the sea level.

Winters in Colorado are cold but sunny so the road surface is mostly dry; snow melts away in a day or two so 359hp is no problem. In fact, on Sunday at the local road track I'll be on my E85 tune

If not I'm probably making 400whp yay lol

ah that could be it. i remember hearing something about the intake system. always assumed the squished upper charge pipe would fall into that category.
