Ok guys im going for 75, since i lost my 50shot n20 jet, i think its a sign telling me i should stop waisting time on 50 and to step up lol. I just wanted to know whos runnign 75 with the stock fuel pump, since its recommended to upgrade the pump when u go above 75. on the dyno 50 was very succesful and added exacly 51hp and 61lbs. so i assume moving up to 75 and keeping bottle pressure at the right psi should be just as good of results.

Will i need a purge kit, since when i 1st spray its only going to spray fuel and air in the line and then nitrous. will that fraction of a second that it sprays only air really be a risky thing (backfire)?

Pity reply....

 

werd up y0....

 

There is a way around the purge kit. When you are doing the burnout at the track you usually go WOT in the water box. Some people just press the nitrous for a second while doing a burnout, it will just makes the tires spin faster, you're not going anywhere anyway. There is your purge....

 

Doesnt that defeat the purpose? You want to purge to get the air out of the system so you dont run straight gasoline through the intake manifold and have intake backfire.. If you do it in the waterbox gas is still gonna go into the intake without any nitrous and then boom.

 

you can have a boom anytime anyway. This is the reason I took off the nitrous anyway. Most altima guys lost their engine, and they weren't even spraying when the engine went.

 

Removing the nitrous is obviously not an option here, so thats irrelevant.

Theres no need to take the risk now is there?

 

maybe. If you want to run nitrous and have a device that turns it off incase it breaks is very costly. Most nitrous guys just run a basic system with a bottle heater and that's it.

It wasn't worth it to me because in order to run nitrous completly safe you need a fuel pressure switch, window switch, blow down tube, nitrous gauge, a good tune, purge, and a device that turns off nitrous incase something goes wrong. Unless you have all that then a chance of blowing the motor is pretty slim. I couldn't afford to blow my motor and I can't have my car sitting dead, I need reliable transportation.

 

did u guys run ur lines under ur car along the fuel lines? or inside the car through the firewall? or where??

 

mines goes inside and thru the firewall

 

run it thru the car like you would a power cable, the exact same way

 

Only 2 things you need are the fuel pressure safty switch (29$) and the RPM window switch (100$). What good does a guage do? While your spraying and racing and chit, do you really have time to stare at a guage to make sure everything is ok? ***** no! You have too many things to worry about besides the fuel pressure guage and the n20 guage... for $129 these 2 things will automaticly protect your car for you. That's not really too expensive.

 

Well if you want to run at the track they require a 3000psi blow off cap, blow down tube and a nitrous gauge. If I didn't have those they wouldn't let me run.

 

Where can u buy a fuel Pressure safety switch?

 

try summit or any speed shop.

 

nopi, NX website, ect. It is like $40-$50.
