Well, lets see, if the capacity is 1308 cubic centimeters then I would assume that means the capacity is 1.308 liters but you would be more familiar with the metric system than I. Smart aleck! I get paid by the word - didn't you know? {:>)

I don't really know the volumetric efficiency of an REW engine, but I would assume that with ideal intake it probably between 95-100%. Of course with a turbo the VE is greater than 1.

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
