Anybody trying this with a roots-style blower? I am having distribution problems. 6 of the cylinders and fine but 2 of them melt the ground electrode.

Specs:

355 small block Chevy
Dart Iron Eagle 200cc Intake ports, heads 72cc chambers
Flat top pistons 4 valve reliefs
Performer RPM camshaft
All new valvetrain
B&M 144 blower with 7psi boost
32 degrees total timing

Heres what happens, launch at 2400RPM, nail it and go about 20 feet then engage the nitrous. Car goes like a freight train but starts to nose at 5500rpm. Shift to 2nd car pulls hard again but starts popping at top of 2nd gear (5500rpm), shift to 3rd pulls hard but halfway through engine lays over really bad and have to lift!

1. I tried running a seperate fuel system for the nitrous with race gas in it - no change!
2. I tried increasing fuel pressure on the nitrous side - car slows!
3. I tried increasing the pill size for the fuel jet in the plate - car slows!

Basically what I gather from this is that the car is not going lean? The car totally lays down in 3rd gear and is actually faster OFF the bottle! Is it detonation? I can't hear anything over the exhaust.

I need help with this before I tear something up. :0

If you want numbers, I went from a 12:28 off bottle to an 11:46 on it. MPH went from 111 to 119. My nitrous jets were equivelent to a 150hp shot.

You nitrous guys, please reply! Thanks....
