Hi Paul,
I know you're a proponent of P-porting, but if someone only wanted to
create large street ports in a 20B which porting templates should be used.

Thanks,
Don


I have no idea what works best because we have not heard from enough
people that did it and flew it in an airplane. IMHO it is not
cost effective as it is skilled labor intensive but it surely won't hurt.
Only modest gains are achieved and it must be combined with a proper
intake manifold with runners of the right length and diameter.
In other words it should be dynoed to tune it for 6500 to 7500 RPM.
So far nobody has done that as far as I know.

Here is some data and pictures on the subject.
