Attention stockoau: 4l + PD pics!

[superroo]

I've just rerun those calculation for the M90 and come up around the 10psi too.

And i was just about to say the same, for a stock motor, 10psi is more than enough. And adding to that, 10psi from a PD blower will be a better 10psi from a turbo.

If people are going to go second hand M90's i would just be warned about the wear that they have. A worn roots blower will produce alot of heat which is not from a performance aspect or a detonation aspect either.

But for the price, if you could do the fabrication work yourself and the install as well, you could probably do it for under $3000, with a new blower. But that will have no engineering certificate or be road legal, so to speak. But since when did that stop us : :eclipsee_
