m90 on ls1

I'm thinking of doing a custom setup using the eaton m90 supercharger with about 4-7 psi. I'm wondering if the m90 is big enough to feed the ls1.

Without looking at the numbers, its going to be a waste of time to run that small a blower on an LS1.

I had one on a 5.3 and it ran out of breath up top real fast.

I would at least use a m112 blower. But even those are out of steam at around 450 rwhp

What numbers are you looking at. I would like to get some info and think this though before I start tearing things apart to make this work.

Dont even bother with a M90. Way too small to support a 346. A bunch of the 3.8 guys are even upgrading their Grand Prix's to use the m112 blower.

M90 is too small. Need an M112 or you could pickup a whipple head unit
