Hey you guys I got a question for all of you. Ok I know that I am thinking too far in the future right now but I’m just curious. Ok to run a nitrous system for my motor what are the general rules about when to use or when not to use a nitrous system using a shot from 100 to 200. By this I mean does your compression need to lower then a curtain value? Is a curtain cam necessary for using a nitrous system? To tell you the truth I am not familiar at all about NO2, I have no idea how to run it or when to run it. If anyone of you guys are willing to give me a run down of how this works and when to use or not use a nitrous system on a motor I would really appreciate it.

Thanks a million

 

how old are you?

ninja edit: saw your profile, says your a student. which is pathetic. you cant spell certain. not trying to be a dick here but damnit that has GOT to be the most IRRITATING spelling of a word i have EVER seen. and you know, didnt we go to 3rd grade or some stuff like that to learn how to spell? where were you?




as far as the nitrous. make sure youve got good fuel pressure and spray away, personally, id stick with around a 100 shot. any more and you run the risk of messing up your engine, i would run a 125 shot on your engine.

 

Pull out 2* of timing per 50 shot, run good gas (octane booster is cheaper than pistons) don't spray till after 3500 rpm your first time, only spray at WOT. I've sprayed quite a few times (75, 100, and 125 shots) on my stock bottom end and stock heads, no problems yet other than the want to do it again.

 

TonyC Thanks for you reply, nitrous is something I have been thinking about but if I do decide to get it, it wont be for at least a year. I guess it is never too early to start doing research.

SP63, your right that was bad spelling I should have gone back and looked over what I wrote. However, there are two different ways of telling a person that they made a mistake. You can tell them with the same attitude and disrespect as you did to me, or you can tell them that they made a mistake with respect and not being rude. I do not appreciate what you said to me, it is childish, but most of all its disrespectful.

 

No problem, I see that you're building a motor right now. What kind of pistons are you using? Crank etc? If you're looking to use a lot of nitrous or boost the motor in the future, you may want to look at getting forged pistons for it. Hypereutectic pistons are ok for nitrous, but really can't handle a lot of knocking, so if you're running hypers, make sure to play everything way on the safe side. I can't really speak from experience since I haven't messed my motor up yet, but as long as you stay out of detonation, I'm sure some decent Hypers will handle a 150 shot for quite a while.

 

Well to answer your question I’m using flat top forged aluminum pistons (SRP/JE), my compression is going to be high nines and low tens. My crank is cast steel (I wish it was forged), and my connecting rods are 6” made from forged steel (Both are from Eagle Specialty Products). Detonation is something that I am afraid of but I know that there is lots of research in for me before I ever put in a nitrous system in my car. However I would like to go for a 150 shot if I ever do decide to go with nitrous. Thanks again for your help, and for your input.

 

“safe” never… if you don’t want it to break don’t start it, park it a hermetically sealed, climate controlled bunker…

The more power you push through the faster it will wear and the more likely you are to find a weak spot and carry it home in a bucket. The same deal with anything that adds power suddenly. If you can’t afford to do that then you should probably reassess spraying it, using it as a race car…

As far as timing and compression… N2O engines are not as sensitive to either as engines with other power adders or even NA, the biggest issue is to make sure you never run out of fuel or see detonation. Conservative timing and cool plugs do that without costing power.
