hello all, man that was a close call!!! I couldn't imagine the butterflies closing at higher RPMs. It didn't make any sense. I am attempting to get better flow in the plenum farthest from the throttle body. When I extracted the valve train the intake valves for this plenum showed evidence of fuel dropping from the vapor stream too early. When I shot water down each plenum the other runners caused twisting streams of water. The farthest plenum had a weak jumbled confused pitter/patter stream of water. Looks like there is about 3 line of sight turns in the plenum alone. The stream probably gets jumbled by hitting one of these curves too hard and angling back crashing into the mid-stream. So the velocity is negated (like cancelling a wave by sending a wave back against it?). Prob. why the fuel is not making it to the chamber?
I thank all for confirming what has to be common sense to an O2 molecule.
