Ferrarist75 should be qualifying in the top 10 on the grid
Angle of throttle to inlet runners ???

Why do the runners exit the plenum at 90 degrees??
To me that must cause turbulence because the air has to flow through a fairly sharp 90 degree angle in order to exit the plenum and enter the runners.
Which setup is better and provides maximum end power - when throttle body position is 90 degree against intake runners or directly against it?
I have no packaging issues, so can use both ways......

Dave Walker did an investigation into this at Emerald on their engine dyno.

Reported in PPC magazine and their website here:
