M90 SC? looking for input

[Shadow24V]

ok, i was kicking around the idea of putting an M90 S/C on my 24v 3.0. I was wondering if anyone had some thoughts etc or if they had used the M90 before. i was thinking that with F/I i can use the 1000 more rpms i can eke out of the bottom end. (24v head runs out of steam N/A around 5500 +- 100, redline stock 6500)

i will probably have to limit myself to about 8PSI to begin with, since the 9:1 cr and not so tight quench area on the pistons are prone to detonation above 8PSI. it MAY be possible to run more than 8 psi, but thats a 50/50 shot. some people in the 3g world blew up at 9 psi, and i know of one that is running 15+ psi on stock internals so *shrugs*

RIPP has a centrifugal S/C that claims ~300WHP at 8psi, but i cant afford their super base (no injectors or computer) kit is $2500, and a junkyard M90 can be found for ~$200 . since i already have a MS computer, all im missing for FI so the SC...... so any input/advice or practical observations would be most appreciative

I ran my M-90 upto 15psi for a long while on stock internals on the 12valve 3L. Sounds like a great project and 8psi will be more than enough to give you a perm sh!t eatin grin =D.

I will be running approximately 7-9lbs boost with a stock M-90 and an underdrive pulley.
