535whp Prelude
The dyno graphs show the power levels at 10 and 16psi of boost. Pretty awesome stuff.
That's the most power I've seen a Prelude producing; its always interesting to know what can be done with the right time and money but also to see the modifications required, although I imagine the torque steer must be horrendous!
This page shows the parts and details half-way down along with several other big power H22a blocks. Dyno's page 40
Check out the EG Civic with the 580whp 450ft/lbs H22a block!!
Crazy!
