What do you mean ?

Its in a vacuum, so no problems with that with the A/F velocity it will be under.

Most inline guys turn the blower up so the bottom actually faces the head ports straight on, so there is no bending of the airstream as the charge exits out of the blower. So you'll have to fab an intake, or I can draw you a 3D model of one so you can make it.

Per Eaton, the coated rotors are not to be used for draw through. The self clearancing coatings will dissolve. The effect will be lower efficiency of the blower. I've not heard of these blowers operating at boost levels as high as 20 #. Not saying it isn't possible, but this is a blower, not a compressor. The high helix rotors blow air, they don't operate like a low helix compressor. They also have a bypass. This is for low throttle settings. The butterflies close the moment the manifold goes positive, and open when the manifold goes low.
Avoid the GM units. The early ones were M-62's, and the later ones M-90's. the throttle body is mounted on the end. They are too long for a car with a firewall and brakes. GM mounted them on transverse engines.The smaller unit will need a lot of over drive to make numbers on a 3.7L. It is arranged the same as the GM M-90, so is too long.
The Ford M-90 will work. The 112 will be capable of better efficiency at lower drive ratios.

He has the hardware to do it, for sure. Any engine that can twist off a 904 input shaft is bad ass in my book. He did that at Vegas.... just twisted it off... That's big-block torque!

With my limited knowledge of the technical side of supercharging, I seem to remember that centrifugal supercharging is somewhat more efficient than the positive-displacement type and less likely to raise the charge-temperature for any given amount of boost. That would be an advantage on the street with pump gas.

I would think that a centrifugal blower would surely get the benefit of some consideration... particularly, as regards packaging, in this case.

Mine has remained trouble-free for a number of years, and makes good boost by 2,000-rpm on my 360 Magnum... pulls like a freight train throughghout the lower rpm levels (so much so that traction in 1st gear is a real problem,) but a slant six could be different... however, Nitti's car pulls the wheels on launches, so I dunno...

My 2-cents.

Good luck with it whatever you decide!!! You pays your money and you takes your cherce!!!!
