"With the cylinder head you ported & polished, I made 38 more Wheel HP at the same PSI. I went from 240 to 278 WHP! Torque stayed the same but the curve is now nice and flat, not peaky as before.

I now need a larger compressor wheel on my turbo to keep up with the awesome flow of the head. Not a bad problem to have!"
