Hello. I am here because no one else has good info on the m90. I am planning on mounting a m90 to be used on my 4 cylinder car just as a challenge and project.
The crank pulley doesnt have as many grooves as the supercharger pulley...it has like 3-4 grooves. It is also 4 7/8" in diameter. The supercharger pulley I am planning on getting is like a 2.5" diameter...to compensate for the smaller crankshaft diameter.
4 7/8 X 3.14 = 15.3075 (crank dia.)
2.5 x 3.14 = 7.85 (supercharger dia.)
15.3075/7.85 = 1.95
7000rpm X 1.95 = 13650
I have been reading on here and it looks like the smaller pulleys like to slip. I plan on compensating by having the pulley sandblasted and possible having crosscuts by a machinist perpendicular to the grooves.
I have a megasquirt for fuel and timing management that was previously on the car or might use the stock computer with a msd boost timing master and a fuel pressure riser.
Any thoughts on how this blower will perform on my 1.6???? Is this too much blower for the motor?
