Hey andykrow,

I have attached an Excel sheet with 4 cams.  For this comparison I simply only changed the cam specs as published by the manufacturer or supplier.

I chose those cams because they closely match my desired power gain in torque in the RPM range I use the most.

These are just predicted numbers from my Engine Analyzer software, so they may or may not be what we would see on an actual engine dynamometer test.

Please compare the numbers for the CompCam 252S and the Schneider 244-50F... interesting numbers?

Based upon those numbers my choice today is the same one I chose about 13 years ago for my 22R the CompCam 252S.

The engine specs are:  1986 22RE, .020 over bore, 1mm Over-size valves, Compression Ratio 9.6:1, header and free-flow exhaust.

The dyno program running conditions are:  29.82 Barometric pressure, Intake air temperature 80d F, Dew Point 37d F, Elevation 1,000 feet, Coolant Temperature 195, Fuel 87 Octane.

See attached Excel Sheet.

Please let me know what you think.
