There is no way velocities in a four runner intake can ever approach those
of a two runner p port. IMHO, Jerry
The reason
I question the velocity theory is that my system uses a Mazdatrix intake,
which combines the primary and secondary in the first 5 inches or so, then I
have two runners (one for each rotor). These are only about 41 mm
ID, which are really too small for max power. There should be
absolutely no shortage of velocity, and the throttle response was still horrid
with remote mounted injectors.
The good
thing about this is that there's nothing unsafe about testing it. You'll
know exactly how it works before you ever line up on the runway to fly it,
so there's no harm in trying it. I flew mine for about 5 hours, but it
scared me enough that I changed it
quickly.
I forget,
what plane are you building your engine for? I know you said you
hoped to have the engine running by the end of the year, but when do you
expect the plane to be done?
Cheer,
Rusty (need
to go pester some customers)
