    In my never ending quest for information, I have this to ask (I already asked a trusted friend but want a discussion):

    With my stock bottom end, Vortech kit pushing around 7-7.5 lbs on a SAFE tune, and a rwhp somewhere around 490-500 peak, could a small shot of nitrous be an option? Say 50-75 shot? What would I need to do to accomplish this? Water/meth kit (would that help?)...

    *I know, as per usual, I'm dreaming and there's other things I could do, but entertain me with your combined wisdom.

    In my opinion, Jason, with the 7 -7.5 psi on the stock bottom end, you are already pushing the limits. I would not add N2O unless you have money saved up for a new motor. JMHO

    I wouldn't, without forged pistons and rods. Erik (Hemi31) proved that a stock crank with forged pistons and rods can take it. I don't know how much boost the new owner was running, but he was spraying also when he ran his 10.68.

    No one's ruined a stock piston yet.

    (unless they were improperly tuned)

    It may be the weak link, but no one's been their yet.

    Properly tuned - you could throw a 75 shot on there. It would have the added benefit of cooling the charge air.

    It's the "properly tuned" problem that gets them.

    So, we know of a few good FI Hemi tuners... would these be the same folks to tune for N2O also?

    *I ask because I don't want to dump $$$ on a tune, then add a meth kit and/or nitrous or whatever else, then have to spend more $$$ on an additional tune. Basically, I would ideally like to just do one knock-out mod/tune and be done with it for awhile.

    You need two tunes to use nitrous well.
    The computer cannot tell when you are spraying, so you need a normal tune, and then a nitrous tune.

    OR - you can just make sure you're spraying fat. But that's not ideal.

    The question becomes "why?"

    I wouldn't recommend it at all.

    There's many reasons for nitrous. Most are childish, one is for drag racing on a track. I weed out the childish reasons, and am left with nitrous as a track-only mod. That's not what you want.

    There's some truth in that... I simply enjoy the kick in the ass of HP... unfortunately, I'm on a budget that makes Ryan's lunch expenditures look huge by comparison... wait... ah, never mind... LMAO!

    In all honesty, it'd be more of a toy, for opening her up now and then... more for self-gratification than anything.

    In the amounts you'd be using, you're not going to get the gratification and seat-of-the-pants feel you're looking for. At a 75 shot you'll be looking at the guy in the seat next to you and saying "you felt that, right?" "that made a difference, didn't it?"

    I doubt the answer Jason would be looking for would be the same as yours Matt. LOL


    Matt I think some of the early Kaboomer's had decent A/F, but with the use of a WOT switches at to low an RPM, it created to much cylinder pressure.
    Detonation didn't colapse the ring land, to much cylinder pressure did. Detonation with leave marks on the heads and the pistons, cylinder pressure will not.

    I can agree with that. But although it's not AFR, I'd still lump improperly engaged nitrous in as a tuning issue. But we're splitting hairs at that point.

    Oh BTW: I can't let that one slide. Nice! LMAO.

    O man... I got comments going off in my head like a 4th of July finale but since we all went to sensitivity training yesterday I'll just bite my tongue -- dammit, dammit, dammit :grin:

    Momo, you want more on the top you turn up your blower. So you're looking for the low end punch. Otherwise what you're actually saying is "I want to go over the safe limits just every once in a while... I'll risk it and probably get away with it". but I know that's not what you want to do right? So lets say you just want to fill in the bottom of the rpm curve. It's going to be way more involved than putting on a CAI. It's also not one of those "set it and forget it" things either. At the least you have to monitor your bottle, there's all those switches, heater, yada, yada and all that plumbing you should be checking every now and again. You'd want one of those fancy controllers so it turns off when the blower kicks in instead of the big red manual button... Did we forget about the power train warranty you still have? and then there's the tuning JMatt mentioned. I just don't see it as a mod for you.

    Thanks for the honesty and insight, Dave. You all may be right it maynot be for me... either that or I'll go with a 275 shot, and forever remember that ONE time my car reversed the rotation of the earth...

    Jason, don't do it, not with kids potentially in your car, that's too dangerous. I know the bottle's in the trunk but still, I wouldn't.

    That being said a small 50-75 shot was next up on my mod list for my Mustang years ago before I ran out of money (ie had a baby, lol!). Running 8.5 psi boost I wanted to add a small shot not for the hp but for the cooling benefits and for that it was gonna be well worth it as I have no aftercooler. In your case being as you have one I wonder the actual improvements you'll reap. Plus being only 50-75 and not really needing those cooling benefits the question becomes ... why bother? All this JMatt said and I agree with him. Imo tho the saftey issue is bigger, with having kids around it just doesn't make it acceptable for me. My 2 cents.
