I have a 355 lt1 with 9 to 1 compression with an sts pushing 14 pounds of boost problem is the turbo does not spool till about 3400 rpm and i'm looking for some more low end hp to get me out of the hole. i have a NX wet kit already in the car and i need to know that would be a good shot for my application.

What heads do you have on the car? and have you dyno'd it yet?

The reason I ask about the heads is that I've found stock LT1 heads don't like to see much more than 700 hp at the wheels before they warp and puke out antifreeze into the oil pan.

Since I'd be a little leary on making too much power with thoes heads, here is what I'd do.
Also, you haven't given any motor specs, so I'm assuming the bottom end is built to handle the power.
Run a 100 shot through your NX single nozzle, but run it through a window switch and shut it off early. For example on at 3,000rpm and off at 5,000rpm. This would work well if your motor redlines at say 6,500rpm.
Basicly you want to shut off the spray well before your turbo builds peak torque.
If you have a dyno graph of your car already, then just look at the torque curve and look where it peaks, then look at what RPM it is at when it is about 150ft-lbs below peak and that is where you should shut off the spray.
Hopefully thats clear.


Dave sells a nice window switch that I recently used, which incorporates the TPS signal, and has gear lockouts, which might work well for you.
