I have a 402ci making 520hp n/a. I have a walbro 255 pump w/hot wire kit and 38lbs injectors. I have a timing tunner to retard when the n.o.s comes on. How much can this fuel system take? I would like to hit a 150 shot and I have a T.N.T wet kit. This should put me 650 rwhp and will check it on the dyno to be safe. Thanks. Mike c.

 

i wouldnt put it past that walbro to supply both a 520 Hp and a 150 hit.... for your own piece of mind, install a dedicated fuel system for the wet kit.... it is always cheaper to do things right the first time.......

 

I agree talk to on of the Nitrous tech sponsors and ask them. Do you have HP tunners to check your injector duty cycle?

 

We have typically seen the Racetronix style systems support around the 650-680rwhp mark. In theory you should be ok but if wanted to be 100% sure then i'd put a dedicated on it abd that would cover you for fueling now and if you decided to step it up later.

I'm spending another 2k on my car and didn't want to spend another $700+ on a fuel system. I will spray less if I need to. Just wondering what my fuel system could handle. This all will be checked by my tuner on the dyno to be safe. Thanks.
