I do not want to spend over $550. What brand NOS and how many horse should I use? I want to use as much as possible without damaging the engine. I plan to run a fuel pump just for NOS. My specs are in the sig. Also one shot or dual shot? Can't I just hit the one shot twice?

 

I have used both the NOS and NX brand N20 kits and I perfer the NX myself. The quality of parts that come with the NX kits are alot better than NOS's. As far as HP,if your on a stock crank and rods you'll want to stay at or under 150 shot.

 

If I do the 150 shot how much time can I expect to gain in the 1/4 mile. I am only running 14.82 with all the mods I made (see sig). Also, at 150 will I need to run another fuel pump. Right now I am running my stock fuel pump from the TPI I used the mallory three port pressure regulator and am running about 7psi.
