This is with stock twins and up to 15psi.

I'm interested in trying out the Hooker header aero chamber muffler that flows 441 cfm. Not sure if that is suffice for the FD.

(i have a feeling that know one knows)

I could always default to the dynomax at 1000 cfm.

From the rx7 archive at team.net:
"many knowledgable tuners believe it takes 1.92 cubic feet per minute to make
one rear wheel hp.

Based on some rough calculations I'd guess 700CFM.

That is why we get such bad mileage! Those are V8 numbers.

My 396 ingests a maximum of 746 cfm @ 7,500 rpm according to my dyno sheet.
