anyone use nitrous before?

[vashxj]

just wondering from any people with actual experience with this what things did you have to do special on your engine for the n2o system (like plugs and gas) that kind of crap

my first 4.0 was a renix with close to 300k miles in my 87 Cherokee and nothing done to the motor.i installed a nos style dry set up jetted at a 75hp and never had any issues.i prolly sprayed 35 bottles through the motor.that was back in 2001.i have been spraying my 96 since 02 with no problem .in 08 I finally built a stroker with forged pistons.

Dry? What did you do for fuel enrichment?

[vashxj]

marty what plugs and fuel did you run in those and any thing else different. I have a zex 125 wet shot going on mine I was just wondering a have never used any before I just wanted to talk to someone that has done it

I have been using a nitrous works wet kit since 04 jetted at 100hp. your zex kit should work great.

o I didn't look at the post close enough I ment to ask scalper, but thanks im assuming you were running 93 or greater gas when you were spraying?

I just run a wet kit, and 93, never had to touch timing or plugs.

how long do you spray for or do you just tighten your seatbelt and go all out?

I run it from 1880-2500, depending on how hard I launch, clear to 120+mph. I spray right off the line. And if its a big race, Ill stall 2500, spray on the drop, and hold the spray through to 5250.

only have had one backfire, and it happened when I was running to rich, luckily I have a VERY nonrestrictive intake, so it just shot flames back out the TB. It happened by being at high speed, high rpm, and let off the throttle before the I let off the spray.

other than that one time, no other issues, and I have over 1,500lbs of N20 through this motor already.

yes I run 93 octane..

Hey I forgot to ask what kind of spark plugs were you guys running

[mountaineerjeff]

I just either run the OEM coppers, or I normally run the NGK. Ive always had the best luck with the ngks, and while I should step mine back, I havent even went to a colder plug yet
