Thermal Efficiency

Post by 38kronik00 »

Does anyone know the the thermal efficiency percentage is for the Gen III M-90? I cannot seem to find that info anywhere. All I could find was Eaton's TVS supercharger which was 76% IIRC.

Also on the Series II what is the stock boost?

I have the data for the M90 Gen3 and Gen5 TE, but can't find it right now. Stock setups with the M90 typically produce about 7psi. Keep in mind, as boost increases, heat increases. Spinning it faster also COSTS more power. Both of these factors determine the law of diminishing returns. Each change in pulley diameter (smaller) nets less gain than the step before.
