I was searching for info on a MARCOTTE redrive that was mentioned in another thread and found a rule of thumb for determining volumetric efficiency..
<paste>
You can roughly calculate the VE of an engine if hp is known with:
VE = 5600 X HP divided by (RPM X Displacement in cubic inches)

This was in the context of a Corvair engine so I do not know if the dynamics involved are comparable.

John, here is a URL to a pretty good discussion on reading compressor maps with examples http://cybrina.mine.nu/MR2_Docs/compressor_flow_maps.htm That's great, Ed. And you did it in one sentence. :)
Do you happen to know the engine capacity (in litres) and the volumetric efficiency of an REW engine?
Regards,
John
John, the auto people use 2.6 litres and .55 for those turbo map calcs.
HTH, Mike
