EFI Intake

Hi Wayne,
        For optimum distribution, the TB's should be one on each side of the
plenum, staggered in the center of the runners,,,,,but with enough plenum area
TB placement is not of much concern......btw why two TB's?????  I can get you
a 2100cfm+ throttle body,,,it is dominator bolt pattern, has two large oval
butterflies, can be progressive or 1:1, uses GM TPS & IAC,,,,,,,,just a
thought.....hth's

 To anyone interested,
   I am currently designing a plenum box to be cast in aluminium to fit on top
 of a tunnel ram manifold for a BB Chevy.  The plenum will be about 80%+ the
 volume of the engine and all opening will be radiused to enhance flow. My
 concern is that I will use 2 throttle bodies to supply enough air, I want to
 make about 750 HP, and where to mount the TB's on the plenum so as not to
 disrupt air flow to the runners. Any assistance would be greatly appreciated.
    Thanks in advance.
 
           Wayne
