ok i thought i had the right jets in but i cracked a piston after 4 passes could some one help me out i got a nos fogger wet kit.im gonna redo my n20 with window and full throttle switch and i want to get a fuel pressure switch but i dont know what psi switch i need.if someone could help me i would really appreciate it.

 

I wouldn't have sprayed that kind of shot without a FPSS and a window switch. The jetting could be fine, but if your car wasn't supplying enough fuel, that could have been the problem leading to the cracked piston. Just pickup one of the FPSS switches from the Nitrous Outlet or Harris. I know the NX ones comes preset at around 35psi and you can adjust them to your liking. I would also put a fuel pressure gauge on your car and see what the fuel pressure is doing at WOT.

 

yeah i shouldnt have but i did and now im paying for it and i dont want to do it again.

 

can any one help me out on this i would really apreciate it.

 

give me a call tomorrow and I can go over all the options with you.
