Got you on the TPS and IAC, I assume the HP will be fine with the dual TBs.

When you say the duals perform a little better, what are you referring to? Tip in, tuneability, air distribution ?

Thx


HP or Dominator EFI would be my choice. Both can drive both IACs if you need more IAC air for idle control. Tuneability is easy with the Holleys in either case. Also, dual 4150 TBs are nice on the street with their progressive linkage, yet flow like a bandit at full throttle. My racer customers running dual TBs give up nothing on driveability yet picked up some HP on the dyno and a little better ET.

I even have one customer running dual Drive-By-Wire TBs on his 1000 HP HEMI so he can soften the tip-in even more.



Rich wouldn't progressive linkage be a problem on a stage v manifold the way each plenum only feeds 4 cylinders?
