is my fuel pump sufficent
 

i have a 140gph pump i was wondering if that is enough for my setup you can see my setup in my sig i went 12.5 with a 1.7 60'

I would say you easily have it covered.

Later,

You've got enough pump to get you safely into the 10's with a blower car. You can support 700hp N/A or 580 with a turbo or blower.

Looking at your combo, I'd say you're doing alright already. If you're looking for best et and not worried about fuel mileage, you should switch to a 410-430 gear.
Also the tune up and air bleeds on the mighty demon are set up for a pretty stout combo (cam 240 degrees+ @.050, 11.5:1+ compression) so it may need some changes to work with a milder combo. Worth looking into anyways.

well here is the thing i plan on spraying a 150 shot to 200 shot on top of thatso will that pump support that i know the fuel line wont so i was thinking about T ing a -4an line right after the pump and running to another nos regulator and then to the solinoids what do you guys think

Use a Y-block coming off the pump and personally, I'd use a -6 up to a regulator near the solenoid and then run a -4AN from there to the solenoid. You should still have enough pump since you don't need any more pressure with nitrous, only more volume. A second fuel pump could be cheap insurance when running nitrous though, but I think you should be okay.

Should be fine. I run a Mallory Comp 140 pump, and it feeds the motor and nitrous with no problem.
