You are the first person I have heard of that has one of those things. Is it the single carb or dual carb intake as I have seen images of both. I would love to get my hands on one to play with on the dyno to prove/disprove that it works or not. The general layout has me scratching my head.

Are we talking mix differences on the dyno, or on the track?

The single Carb version may have too much Plenum volume?

Lots of duration, low compression, low stall and a 2 speed make a weak combo. The nitrous (gobs of torque on the launch) show the potential of the combo. A manifold change will help if it builds torque around your stall point.

The truck will never be quick on motor without converter and gearing changes, at which point you won't have the RPM available for the spray.

BTW, nice runs going 9's =D>
