The plan could be to possibly try this on a stock 1600 in an early bay..... pending calculations.

This is what I have found so far from some net research and trying to remember thermofluids/thermodynamics lectures from years back...

Based on a stock 1600cc

Eaton M45 Supercharger (from a mini cooper s)

Engine airflow max (cfm) = (engine Cubic inches x RPM x Volume Ratio x Volumetric effeciency x Pressure ratio)/1728

max airflow = 150.5 cfm = 255.7 m3/hour

Pressure ratio @ 7psi boost = (air pressure + boost pressure)/air pressure

Pressure ratio = (14.7 + 7)/14.7

Presure Ratio = 1.48

Looking at the M45 pergotmance graph that seems to prove the M45 would be suitable. Ok so my volumetric effeciency figure was a guess - need to do some more calculations on that.

I'll add my temp rise calculations tomorrow and inlet pipe diameter calculations- too tired right now.

I was planning a drawthrough system with a single carb very similar to the setup in the thread above.
