I have a built motor and run svo 42lb injectors. On motor the fuel pressure stays at like 43-44psi at wot. I sprayed 100hp through my nitrous outlet plate and it dropped to 32 psi area give or take a few psi. I want to run 200hp through it, but the obvious is that the pressure wont be there. I have a granatelli 255lph pump thats over 4 years old in it with the hotwire kit. What are my options that isnt gonna cost me a rediculous amount of money?

 

I think your pump is bad!!!

 

I'm no expert but I prolly wouldn't shoot any more till you replace the pump. Is it the first time you have shot nitrous in your current setup? Either way I would replace just to be safe... Especially if your going to shoot again IMO

 

Do a stand alone and spray as much as the motor will hold.

 

Stand alone would be great, but I dont have that kinda of cash this second. And I had a nitrous works plate and 125 shot it held good psi and then I put a nitrous outlet plate on and the 100 shot the psi dropped. Alot more holes in the nitrous outlet plate, but still sucks. What is the best pump to get? This is for a 95' Trans Am.

 

It sounds like the pump is starting to give up on you.


I'd suggest getting this pump http://www.nitrousoutlet.com/catalog...0&product=3328
