So I didn't really get an answer last time I asked so here I go again. What is the highest shot I can spray on stock internals? I just ordered a ZEX dry kit and I want to get the most out of it. Would a 75 shot be okay?

 

I could be wrong but I dont think you suposed to blow wet or dry into a stock system? I think you have to do some serius mods to compinsate the compression.I think, as would a turbo. I could be wrong let me know.

 

no you can definately spray up to (I think) 75 ponies worth on stock internals. I know you can spray stock just not how much.

 

wat r u nuts niteous is the last thing you need to modify a car and it will tear up ur car if it's stock

 

Okay I don't know if you guys are newbies to the tuner scene but N2O will not tear up a stock engine if you use it in moderation and it has been properly installed. Using N2O is equivelant to turbocharging, it's another method of forced induction. N2O is also one of the safest ways to add HP. Your stock internals can handle it up to a point, after that you get into compression issues and temp problems. You have to worry about seals and gaskets. Once again, I reiterate, N2O is safe for use on a stock engine in moderation!!! My question is for those who have previous experience using N2O on stock internals in a Neon.

 

You can put anywhere between a 75-100 shot without screwing up the motor. It will wear the motor quicker, but its not much differnt then running a turbo.

 

When you install the dry n2o. say Zex. i saw that it has a hose going into the intake. Is there alout to do to install it?

 

Not really-Zex actually has the easiest kit to run. All of the solenoids and controllers are in a box. All you have to do is connect the lines. The line to the intake is the actual nozzle. Line from the bottle to the solenoid(s), electrical lines from the solenoids to the controller, controller to switch, and lines from solenoids to intake. With a dry kit you only run a nitrous line, with a wet kit you have to run fuel and N2O. Of course like I said with the zex it's all centralized so everything runs into and out of the box.

 

Well one thing to think about with a dry system is that you have to make up the fuel needed to equilize the fuel/air ratio. So if you add Nitrous you will have to see what increase in fuel pressure you will need to make up the difference. You may need bigger fuel injector and increased fuel pressure. One of the reasons why the Ricer boys all have those fuel pressure regulators. Not just for show(at least for the engine boys).

I did the numbers on my old suzuki and found that stock injectors would work ok with fuel ressure increased to about 70-75 PSI(Stock is 35-38PSI). And most 4 cylinder cars 50 was the boder line as long as you cranked up the fuel pressure. So there is some math needed to be performed and you need to know stock fuel pressure and injector size. The current and expected HP figures. Thus leading you to how much fuel pressure you will need to add(about 75 is really about the highest reasonable) or what size injectors you will need to add in addition to the fuel pressure.

Once you know this you can then and only then run a DRY nitrous setup effectively and safely.

Yeah, yeah, I know MATH AAARRRGGGHHHHH!!!!!! But it is car math it will be OK!!!!

Other wise GO WET!!! This way you add the make up fuel and do not have to mess with injectors and fuel pressure. But adds other plumbing problems.

 

well since neons run so rich I really don't think it'll be a problem.
