Alright, I just had a NX wet kit put on my car. When they put it on the dyno it hit 300 motor and 410 sprayed. Problem was they said I need a new fuel pump. So Im going to go ahead and replace the fuel pump. If I do that do you think it would be safe to up the shot from 100 to 150 on a stock engine?

 

I now have a new fuel system, but the numbers in my sig were on a stock pump....
H/C/I and 125 shot...510rwhp.
I would say its a good idea to get a pump but it would work without. 150 no problem with a pump...you might want to look into retarding timing etc...i havent done a thing to mine yet but will when i increase my shot to a 200...

 

thanks man, Im gunna go ahead and do it then.

 

what kinda pump do you suggest?

 

If you have plenty of money to replace the motor, then it's safe. I have a forged motor with Racetronix electric fuel pump and 30# SVO injectors. 150 is all I can safely spray. On your '99, you have the smaller 26# injectors and are already max'ing your injector duty cycle rate. Anyone who tells you to spray a 150 NX wet shot on your setup is out of their ******* mind.

 

X2! i know from experience

 

Ive sprayed a 150 shot a few times on my stock fuel pump.... I did need new injectors though. I bought a set of 42lber's. My intake manifold wont allow me to run a 150 shot right now, so I backed it down to a 100 shot and she runs great.... I would say to be safe buy the fuel pump though....

 

whats wrong with a 150 shot on his motor? i can say that i personally have 2 friends that put a 150 wet shot on their car with nothing more than TR6 plugs and they all ran great. a fuel pump would definitely bring you up to what that 150shot is supposed to give you and be safer.

 

A wet shot has nothing to do with maxing out injectors. If you were spraying a dry shot then yes I could understand. A wet shot adds fuel with nitrous. Stock injectors and fuel pump with a 150 shot is very possible. All these myths that are being talked are just that, myths. I would pull some timing out of it, but otherwise fuel system should be ok.

I agree

 

Yes...your fuel injectors would have nothing to do with running a wet shot. 150 is perfectly safe for a stock(ish) f body.

 

yep,I spray 150 wet on mine also have been for over 3 yrs. with no problems.....I do have a fuel gauge. N/A it holds 58-60lbs. but when I spray it drops to around 42...so what I done was just adjust the jets for that fuel pressure (42lbs.) so far so good.Mine came out to 63n...36fuel and thats with 42lbs. fuel pressure.But now that is nx wet kit and thats 150 at the wheels and about 180 at the motor.
