Runnig DR's? If so, a 100 shot should be able to just launch full out. Just haze the tires a bit first, no John Force burnouts. You should see 12.5's 12'6 easily.

With a 100 shot you should pick up almost a fulle second. I got .8 spraying from second gear on in my TA. My guess is you need a little tuning.

In your sig you say no NX or TNT. I run a TNT system and it's stock jetting is horrendously rich.

Running their recommended 75RWHP N2O/Fuel jetting netted me off-the-scale richness on the dyno. Ended up being about a 55-60RWHP shot.

After the dyno I tossed in the 100RWHP N2O jets and left the fuel jets alone. Big, big difference. Totally different animal on the juice.

I think these guys sell the kits with a quite rich recommendation for litigation purposes. It's tough to blow up your engine running below 10:1.

Mine hits when the pedal hits the floor, right off the line. I went from a 13.00 to a 12.1 with a 100 shot and I was pulling out 8 degrees when it is activated. I use et streets and my short time was 1.7.

I have a set of M/T ET streets at 14 psi of air. I still have some tuning to do, next time I am only going to take out 4 degrees when activated and see what that does.

What is your bottle pressure when you are spraying? If you are not up to the right psi you might want to invest in some bottle warmers. It will hit alot harder.

:lolg: lmfao i would launch my 150 NOS wet shot right out of the whole! never had a problem with the motor or burning up pistons. As long as you have fuel in that bad boy you should be fine hit it at 1000rpm full throttle should have no problems except for tire spin and smoke!

:D

Very true, maybe even 2500 rpm,however, it may take some "trick photography" to notice, but mashing the gas from a standstill, the engine revs to 2500/3k slightly before the pedal hits the floor. Prolly not visible to the human eye, but it does. :yesnod:

Make sure you are purged.
If your all purged, running DR's and you hazed the tires a little, there is little else that could keep your short time from getting better. :confused:
