Re: 0235 vs c90 for a float plane

What do the O-300 elbows give you (compared to the regular elbows)?

They dont have the divits for the fuel injectors and they are about 5/16" taller which makes the elbow transition a little smoother. The Reno F1 guys use them so I have been told. Supposed to be good for 5 hp. Tim

I've got them on my engine but don't think they give an extra 5 HP. Maybe with total flow-matching.

Probably right, 5hp does seem like a whole lot. Probably the elbows and entire induction cleaned up would help to get 5HP on our engines . The
Reno engines are making almost twice the power of ours and at 4200 RPM
so they would notice a bigger difference anyway since the air volume is that
much greater .
