welcome to stangnet, nice set-up, post some pics.

I'm gonna say mid 10's to low 11's if you've got it tuned right and you drive it like you stole it

did you do any type of roll bar, airbag or clearance the rear fender lips? I launched at 4200 and squatted on my 28"s destroying them.

I'm a little worried about those 30 lbs injectors.

RC Fuel Injection

use the calculator at the bottom of the page. If you did an estimated and conservative 400 flywheel horsepower at a N/A BSC of .50, a safe 80% duty cycle and 41 psi fuel pressure it needs a minumum 32.19 injector. I would think he'd be easily 500+ at ethe flywheel with the NOS.

I would think it would need at least 42's. I just sold mine to go 80's.

Never had a problem here. You should switch them to a 10" wheel though, they will work alot better at the track and on the street.

There are so many variables its hard to say what it will actually run, could go anywhere from a high nine second pass to a high 10/low 11

Usually, a Nitrous fogger system will seriously increase the fuel pressure which will help the 30 lb injectors. However, I'm not a nitrous pro, so hopefully someone else can chime in about that.

All I know is that with that cam, Heads and intake he's going to be 360+rwhp for sure, maybe 400+ depending on the tune and more details (high comp, and other bolt-ons). I made 420 with 30 lb injectors, but it's definitely toeing the line. I honestly don't know if the nitrous will be too much. That's why I left my post somewhat vague.

Well iam goin to give it a shot with the 30lb injector and i can always step up. But in the injector cal you don't add the nitrous hp. But we will seen and adapt from there I think the 30lbers will be fine

I'm not sure you have enough injector to support that kind of power. i would look at atleast 60lbs injectors. call joe beagle at dynospeed in memphis,tn he can square you away

idk cause my 60 lbs injectors will only support 620 hp from a blower motor

like i say your car wont run right fuel pressure gonna b low and your gonna be mad if you could of prevented all doubts and just bumped up injectors from the start

Unless its a dry kit, the 60's would be overkill. I think the 30's with a wet kit might will be fine if it runs good with the 30s on motor. The nitrous kit should have its own source of regulated fuel
