Hi has anybody got an accurate theoretical air flow calculation for a 13b rotary engine.

Will it be exactly the same as a piston engine calculation.

I'm melting my own head here so if anyone can help it would be much appreciated.

Thanks Graham

You use the 720 degree equivalent displacement, so twice what Mazda declare, usually end up in the 95-105% VE range if using turbo/fuel consumption calculators, exhaust temps will be higher than piston equivalents too.

Thanks so much for clearing that up wasnt sure about dividing rpm by 2 but I see why now. Thanks so much for your help. You're a super star.
