I was wondering if it is somewhat safe to run a 50 shot of nitrous on an H22a prelude with stock internals. I know that any type of forced induction is bad for a car, but I was wondering how safe I could run the 50 shot. I was planning of getting a turbo, but I realized that it will just cost way too much and I do not have enough money to build up my engine first, which is bad. Does anyone think that I still should just wait and go for the turbo? or is nitrous a semi-safe and good investment to make my car faster when it is needed? Lemme know your opinions. Thanks! Sorry, I'm reposting this because i put it in the FI forum but no body ever answers me there =[

 

Yes a 50 shot is fine on your motor. You can run an 80-100 shot on stock internals from what I've read on others experiences with nitrous. As long as you have the right SETUP. With a 50 shot, just get one-step colder plugs, fuel pressure reg., and fuel pump--that's probably overkill as it is, lol. But it's absolutely fool proof if you set it up right. You could probably get away with just the plugs actually, but I like to go all out when I do things, so I'd be getting an ignition and all the other goodies to run an 80 shot

 

Have any ideas on what is the best nitrous kit for a stock h22a? the Nitrous express claims you can run their kit without engine mods or timing retards. lemme know what you think! ;p Thanks! - Matt

 

NX definately makes a good kit, i'd go with that, you could even do a 75 shot, ZEX makes a decent kit as well, and i've heard good things about Venom, but i personally would go with NX

 

go zex have one for sale just for u im goin all motor cause now i have the money. if you do paypal i will ship it for you 650$ comes with accessories like the purge kit,remote bottle opener you can open it from the driver seat without having to go to the back of the trunk to open it. bottle heater and pressure guage and the zex plugs. thats with everything shipped. lemme know if your interested its one heck of a deal only used 3 times.

 

50 shot is fine....Id go NX because you will see more power from your "50" shot

 

why did you quote the 50 shot? =[

 

And yea, I'll check out the zex kit and NX kit as well. and as for the 650 dollar offer, i would love to buy it, cept right now i only have about 200 bucks saved up hehe. just had my body kit work done, so i'm tryin to save again. how long will the kit be selling for? are you in a hurry to sell it or could you wait awhile? lemme know cause i really am interested. Thanks! -Matt

Because cars with NX kits tend to put out more power than cars with other kits although they are both running the same size shot. The shot size is just a rating either way. The motor doesn't care what size shot you think you are putting through it, it only cares about how much fuel is being combusted in it.

 

Nitrous isn't forced induction...

its all opinion...is a tomato a fruit or vegetable...

when you open the solonoid and let 1200 psi come out of the bottle, your telling me its not forcing anything in the cylinders.

what its not is cheating, it no more cheating then tc/sc.

but to your question, ya a 50 shot is fine, i ran a 75 for a while. and if you like diy stuff, you can build your own kit for about 200 or less.

 

Yeah... A 1200lb bottle going thru a jet the size of a needle. How long do you think it would take to fill up an intake with a hole that size? And to be forced induction, (pressurizing the intake) the intake must become completely filled before it can begin to make PSI. Nitrous is a combustion accellerant, nothing more. Is octane booster forced induction? It does the same thing as nitrous.

 

Actually octane booster simply raises the octane level of the fuel making it more difficult to combust the fuel. Where as nitrous provides more oxygen molecules to catalyze more combustion reactions when extra fuel is added to the equation.

That's why people run high octane in high compression motors. So that they can being combustion of the AF mixture precisely when they want to instead of having to deal with predetonation.

Learn something new everyday.

 

also n2o is so cold it cools off the intake charge, so the air is way more dense. this dense air has way more oxygen molcules, which in turn is forcing more air into the engine, then it could ever suck in on its own.

but it really dont matter, im not starting an arguement, to all their own.

 

Is it really worth it going with nitrous? From what I heard the bottle lasts for about 10-15 uses and then you have to refill (don't know how much that would cost, though), and then you always have to run on high octane like 92 or so...when you might not even use nitrous. Isn't it a waste?

 

You should be running 93 octane anyways in an h22. I figure that running 13.6 for under $1k sounds like a fair deal.

 

Says who? If it is stock with no FI, then why would you run 93?

 

Go with an NX kit, i have heard about solenoids breaking on other kits. Not only that, but NX tends to under estimate their HP ratings.

&lt;--- has a nitrous kit, clutch, flywheel and assorted fuel system mods sitting on his office floor. Man I cant wait until next month...

My prelude says "PREMIUM UNLEADED FUEL ONLY", here in FL thats 93octane

Yes, that is the reasoning behind running higher octane. I was using the analogy of nitrous -vs- octane booster to show that they are both only substances presented to the combustion process within the intake.

The air is never forced into the engine. More oxygen is presented to the combustion chambers, but the jets of a nitrous system are so small that they will never produce enough volume to pressurize the intake runners and combustion chambers. My setup also cools the air, it's called an intercooler.

Yeah, well I figure that if you're running a 13.6 on nitrous and it's not on slicks, then you might want to go ahead and add in the cost of the motor you're about to have to replace to that $1000.00 and make it a little more realistic.


Bottom line is, Nitrous is a great power adder, don't get me wrong. I've sprayed a 75 shot of Zex myself. All I am saying is that it's not forced induction. If you don't believe me, put a boost gauge on your intake manifold. No matter how many bar the gauge shows on 2 Fast 2 Furious, you'll never see it on yours. Forced induction is the ability to produce more air at the intake than the motor can take in, thus making pressure on the intake manifold. Hook your intake pipe up to a -3an nitrous line and try to crank it. It won't crank because the -3an line cannot flow enough air to facilitate combustion on a 2.2l engine. That being said, we prove that there is no way that the same -3an line could ever pressurize the combustion chamber no matter what the bottle pressure.

why would he have to replace his engine, i ran a 13.96 on a 50 shot, so a 13.6 on stock engine is totally realistic. its like a turbo on a stock engine, proper tuning is the key...

like i said its all opinon, so im done now

 

A prelude is a low 15's - high 14 second car stock. With bolt-ons, you may gain a few tenths of a second. Maybe you're right saying it's possible to run 13.6's with only a shot of nitrous, but how long will it last on an already high compression motor? A 13.9 is a damn good time on a 50 shot... That's the best time I've ever heard. I'm not trying to be an ***, don't get me wrong. but I don't think it's fair to tell everyone on this board, respected tuners to new Prelude owners that they can safely run mid 13's with only a shot of nitrous, agreed?

On PO.com there are 2 people running 13.6s. Myself with a 65 shot i/e and another member with a 75 shot i/h/e. We also have another member running a 13.7 with a 75 shot. I'm no master tuner and I haven't installed the S100 and P28 because I don't have my built motor finished yet. The owners of the other two times that I listed are knowledgable people, but they are not heavily tuned either. Neither of them is running a stand alone and only one is running a VAFC. We simply install the kits, get the right bottle pressure, add enough fuel to keep it from predetonating, and practice racing. It's not as hard as people think.

During the track day that I ran a 13.6@104.5 I ran out of nitrous. I was running 15 flat NA in the middle of a hot summer day in Alabama. If that doesn't prove that my motor is healthy then I don't know what does. This is my second year running nitrous. Granted I don't put many bottles through the car, but it still runs fine. I don't screw around on the streets and blow away high schoolers in their cavaliers. I spray when I drag race and that's it.

 

why must people hate...?
