It has been mentioned in a couple other threads but nobody has testified to using it from what I remember. Being in the desert where average highs in the summer are over 105 degrees f than I'm worried about excess heat from a SC or turbo but would love to have some extra power on hand. So if you have any knowledge on how a rotary (NA preferable because its a whole different ballgame on boost) reacts to a little nos than please enlighten me.

 

Rotary engine are like any other when you gas them up. Get the fueling and the ignition timimg right and they love it, get it wrong and they go bang

 

If you are talking about 1/4 mile type stuff, NOS will help with that. But if you're talking about anything else, there are other things that you need to do instead of NOS.

Since you're talking about desert conditions, I would think that water injection would have an even better advantage than it does elsewhere.

water injection would be better except the fact you have to carry around a tank of water @ 8lbs per gallon plus all hoses and hardware. This car will be my daily driver so that really isn't that practical plus it only fixes the intake charge temperature I was talking more of stress put on the drivetrain and underhood temperatures. As far as the nitrous goes I was sure if done correctly it wouldn't hurt the motor by any means, sorry I should have been clearer. I was wondering more with the limited displacement how much you could inject and still be safe as long as you have the fuel to match.

 

???

A water injection setup consists of a small pump, and normally no more than a gallon of water in a plastic or aluminum container. Even considering a NOS setup where the bottle is removed when you're not on track, a water injection setup shouldn't take up any usable passenger space.

Actually, the only time water injection will lower the intake charge temps would be in a forced induction system that has a undersized IC system, and even then, the main benefits are not decreased intake temps, but a more stabilized intake charge and decreased in-cylinder temps. This will also have a benefit in high ambient temperatures in NA engines (whether that's what you want or not, is another matter), but it's not really a HP increase item, more of a stabilizing item.

NOS, on the other hand, is intended to significantly cool intake charge temperatures, significantly increasing air density, packing more air into the cylinders. Rotary displacement doesn't equate directly with piston engines, a 1.3L rotary is roughly comparable to say, a 3.0L engine. As far as matching a NOS setup, I would match it with the fuel injector capacity instead of displacement. The drivetrain and fuel system should handle it as long as you don't get too greedy, just like with piston engines. But you will increase under hood temps with it, just like with piston engines.

Good old giggle gas...well heres the thing...N20 or NAWWWWWWZ, isnt always a good replacement for a turbo. When you start making more power by burning more fuel, your car is gonna get hotter...so heres what i say...TURBO CHARGER!

N2O is a god cheap alternative, but at the cost of refilling it and the shady legality of it on the steet make it more of a hinderance to me then say a turbo.

The turbo, with the right supporting mods can often not effect the wear and tear of an engine, just like any light mod, that much. Also with turbos, i personally feel that you have more control over what happens, and its more predicitable. Intercoolers and radiators make it much easier to keep your engine cool, where as with N2O all you have is the N2, that carries the O2, and a bigger radiator.

 

oh yeah and purging your system may sound cool, but it wastes N20, a BOV makes a cool sound and you can keep on doin it :-D

 

hey velo..maybe i missed something..but is that you fd??...and i thought u were getting a mini?

 

But my main reason for considering NO2 is that I'm only increasing under hood temps for the ten seconds a month I may use it. Not when I'm sitting on the 150 degree asphalt waiting for the light to turn green. I know that a turbo is far superior and the sound of a BOV gives me a hard on, thats not my argument just that I keep seing how rotaries don't handle overheating very well and that concerns me since a turbo or a supercharger for that matter create additional heat all of the time.

 

Fair enough.

YOU MEAN THATS NOT A MINI! :D


yeah its mine....it was a sweet deal, or so it seemed, the overflow tank blew on its maiden voyage. But i go to pick it back up on Monday. The MINI is still technichally on order...till i go get my check for 500 bucks and buy an Apex'i N1 for my ride. I'll post a story in the lounge

 

i've put nitrous on my 96 eagle talon. it loves it. it wont run right without it. completely stock it takes a 100 shot like a champ. but, take it from me... nitrous is not the way to go! it may be cool in the movies, and yes i've actually gotten a girls phone number with my puurge valve, but it has way too many downpoints to be a sufficient resource of horsepower. turbocharger is the way to go. here's a little chart for you....

GOOD POINTS
NITROUS
1) you can get high off medical grade!
2) purging is fun!
3) look! i got NAWZ! your friends will love it.
4) easy to bolt on with a wet kit. installed mine in 2 hours by myself.
5) it's a real bottle. not one of those idiotic subwoofer bottle thingys.

TURBOCHARGER
1) it's always there
2) it makes a swishing noise when you shift
3) hear that whistle? thats the sound of raw horsepower
4) people respect the turbo
5) it works off the untapped resource of exhaust gases.
6) dont wanna run alot of boost? get a boost controller.


BAD POINTS
NITROUS
1) expensive
2) expensive
3) expensive
4) REQUIRES supporting mods to get any real power from it
5) did i mention it's expensive? look at it this way... my 100 shot uses 1 full pound of nitrous every 10 seconds it's spraying. thats 100 seconds out of a full bottle, and $40 gone in a matter if a minute and a half. even a small 50 shot uses .6lbs every 10 seconds. it's worth it at the track, but not on the street.

TURBOCHARGER
1) really expensive to install... but you only hafta do it once!
2) serious potential gains. dont get too crazy and turn up the boost until you do some other supporting mods to keep that power in.

i'm all for turbochargers. they will be less expensive than nitrous, and you have more control over it than a supercharger. to change boost on a supercharger you have to change the belt and pulley. to change the boost on a turbo charger you just turn it down with a little dial. nitrous is just way too expensive...

however... if you still want nitrous... i'll sell you my kit. e-mail me if interested.

Ya know, as much of a horn-dog as I am, I don't think that I'd want the phone number of a girl who is impressed by a purge valve...

merely a conversation piece. she was impressed with my insane knowledge of the operation of high performance vehicles. or so to speak.

anyway, i never called her. *shrug*
