nitrous question

[cjg454ss]

i want to run a 125-150 shot. with a 125 shot do i need to retard the timing or add a bigger fuel pump.

In what kind of car?

[mrr23]

quick search says he has a 2002 SS with all the SLP options. you really have to do nothing as far as fuel and timing is concerned. to be a little on the safe side, bring timing down 2*.

I left my search detective tools in the truck....:)
Go a lower heat range of plugs and do not use platinum tip plugs....

[mrr23]

yeah it would be nice if poeple would post up the car instead of doing a search. and i keep forgetting the plugs.

[cjg454ss]

sorry about not listing the car, im thought it was coming up in my sig.

do i need to retard the timing? also what is the max i can do with out messing with timing or anything other than bolting on nitrous?

You could throw 2* timing at it but I dont feel it to be nesceserry....150 shot (wet) is cool.....I would have your A/F checked just to be safe....I'm replacing engines in my 04 GTO right now...aint cheap man....

how about a 125 shot wet. I have the nozzle shooting right after my mass air into the intake. do i need to retard with a 125? also when should i hit it, rpm? i have 55 nitrous and 36 fuel jets in there now and havent hit it yet. i dont want to blow it up by any means.

Make sure you have a minimum of 900lbs of bottle pressure and hit it when anove 3K RPM....Some say above 2K....but 3K is my happly place:)

is that with a 150 shot or 125?

[mrr23]

on a stock torque converter, i was hitting it at 2k rpms. now, with a 3200 converter, i hit at 2500 rpms. and that's on a 150 in the wife's car and 200 on my car.
