19 lbs of boost @ 5000 RPM on a M90? ITS POSSIBLE
I was bored, looking at supecharger systems, and i came across an amazing idea.
I found a rebuild on an M90 blower that looks like this :
Apparently that modified intake port, by exposing the rotors increases volumetric efficiency by 8 lbs at 3500rpm
This unit apparently produces 20+ PSI with 10% overdrive pulley
I'm going to do a little more poking around, maybe contact them and see about a M90 designed for a GM...

I'm really starting to like this idea.. Its meant for a T-bird, but they use the same blower just different mounting configuration.
Its an idea i dont think anyone on here knew of yet!
We need the gear heads

I wonder if the T-bird engine is lower compression than ours, cause that much boost would bust internals right quick!!! What kind of engine is the T-birds? Is it a v6 or 8?

The T Bird is a 3800 V-6 with aluminum heads. I bet 20 PSI of boost would blow the valve covers off. I had an early T Bird SC. Blown head gaskets were a way of life ...
It ran great , when it ran.

Matt, you realize that won't work on your 95 without a major change in pulleys and a custom lower intake manifold?

Anyway, yeah the T-Bird uses a 3.8L engine, its not a 3800. 3800 is an engine classification used by GM. The Ford 3.8 is a 232ci apposed to the GM 231. The Ford also has hydraulic roller lifters, wedge combustion chamber, and uses more aluminum materials than the 3800. It has a 8.2:1 compression ratio. This all adds up to 315 ft/lbs of torque and 210 hp. Oh did i mention it has an Air to Air IC stock?
I think this idea would work, since there isn't really a need for an IC since the supercharger isn't winding any faster to produce the boost due to its design change.
I have a M62 supercharger laying around, im going to investigate into what can be done to mimic but not copy this MagnaPort II supercharger rebuild.
Hopefully others will look around a bit.
