You're asking about an engine in a prototype vehicle...?
Uh, good luck.

As Herblenny knows, I have an FD powered by a 20b NA using high compression Rx8 rotors, monster street port, custom headers, ignition, with rotating assembly balanced to 10,000 rpm. It was making around 360-365 WHP in early runs. I haven't played with it at all over the winter, but will be tuning it this spring. I don't think it can do better than maybe 375 even at 9,500-10,000, if it can even get enough air there. (But it sounds great at those rpm's...)

The power is just fine, as this setup was developed for linear power, instant response, big low down torque, reliability, and great sound.
