how come I can't seem to be able to find anyone on here running a roots style blower on their car? I would have thought the whipple/eatons would have been popular.
you can get a MP112 dirt cheap you just need a lower intake manifold that would allow you to mount it

 

no one makes anything to make an MP112 a direct bolt on, so it all has to be fabricated. there has been a few guys that put them on, one guy i remember did twin m90's on a jy 305 in a malibu. it was pretty neat.

just fyi, whipples and eatons are twin screw blowers, not roots.

 

I was generalising and actually an m90/m112 is NOT twin screw.
twin screw compresses air before it ever leaves the blower an m90/m112 compresses air in the lower intake manifold.

you're saying you can't get a lower intake manifold to mount a m112 to a SBC? wtf

reason is I'm rebuilding my 383 and because of the cam I used it has no ***** on the low end (under 3500rpm) I wanted to run a non intercooled blower setup with about 12psi to bring the low end back.

 

I'm interested in any info on this as well!

 

there's loads of ways to do it, and it's not that hard... do a search here, saturn5, rooster and I have posted pics and descriptions multiple times.

 

care to elaborate? I did a few searches before I made this post and the guy you linked me to did this with a carb.. I want to do this with fuel injection.
