Think about this: more boost than others at much lower rpm.

Vtec is currently set at 3600 rpm.

The 25 psi of boost was obtained with an impeller speed of about 59,000 rpm. The Mustang crowd is spinning the T-trim to speeds of 65,000 to 68,000 rpm in the quarter mile.

All I need to see 650 rwhp is a few thousand dollars.

impressive sideways! I wanna see you hit 650 with a charger, that would be awesome!

Remember me from 4 years back or so, you took me for a ride while I was at a tournament in HB?

Very interesting! I'm planning on spinning mine up to 60000 with a 3.2" pulley and was expecting 20-22psi

Watch your intake temperatures. The S trim at that speed blows hot.
