Rusty, where were the butterflies located? Jerry
Hi
Jerry,
I was using a
TWM throttle body, with 4 injector pockets, so the injectors, and butterflies
were both at about 30 inches from the ports. It's my understanding that
the issue is with the injector distance, not the
butterflies.
It would be
interesting to try putting only the secondaries at a distance, and make the
staging point as high as you can. This would give you a nice cooling of
the intake charge under full throttle ops, but maybe (key word) not hurt
throttle response that much. This could be particularly useful for a turbo
without an intercooler.
FWIW, the
cooling of the runners was significant. During my initial runs (in the
summer), I shut the engine down a couple times to go look for leaks, since I was
getting water drops on my canopy with the cowling off. Turns out, it was
condensation on the intake runners that was blowing off, and they were cold to
the touch.
Cheers,
Rusty (where
the heck is Ed when you need him)
