Short answer: no

Long Answer: In my opinion, nitrous should be built for and used, or it should be left alone. If you are building a motor for nitrous (Or that is ready for nitrous at a later date) then you should go for an adjustable system.

If you aren't building a motor for nitrous, then this system might be a good rarely used addition.

Remember though, you need to adjust fuel and timing to use it safely and effectively. That's where a lot of people go wrong... tuning a motor for natural aspiration then adding nitrous and thinking they can get away with spraying it "only once in a while." Ever seen a piston melt?

My vote goes for using the money to build a motor that will build more power without nitrous... For about a hundred extra bucks, you can go for a bitchin' damper that will take POUNDS off of your rotating assembly, or get a set of alum roller rockers.

man nitrous is awesome as long as you dont get crazy. Definatly get an adjustable kit. Like the NX mainline system or a more complete kit. NX stands behind their products better than holley (NOS), NX has a lifetime warrenty on their solenoids, and their jets are rated for rear wheel horse instead of crank hp.

You wont catch me using it. I built my engine for maxium power with the main objective being dependability for every day use, if I so desire. JB

anyone used any of these? Empty powershot kit

Post by j Sun Mar 01, 2009 10:28 pm

the powershot kit is a good entry level 125hp kit. any bigger and you will need hypereutectic/ or forged pistons, and better rod bolts. you will need to back the timing off (2 degrees for every 50hp). just make sure your fuel pump will maintain 6-7.5 psi throughout the run. whatever you do, dont run the engine lean (fuel pressure)...this is what hurts the pistons (detonation). this kit will work fine on a stock, or mildly built engine, as long as you follow these guidelines !!! also make sure the bottle is at approx. 900psi (on cold nights the bottle will need to be warmed). i have used nitrous on the street / track for 15 years, and have never hurt an engine because of it. I even use it on my alcohol carbed PINTO, a bracket race car ( only for finish line racing, if it is close).

Hypereutectic would shatter if leaned out. Need forged internals before you play with the giggle juice.

Besides bottles are for baby's. bounce

I like Nitrous, but yea hypereutectic pistons will shatter if detonation occurs, you have to MAKE sure your car is tuned properly N/A and have enough fuel and timing retard to run the nitrous. But I dont think you are running hypers
Detonation has a certian frequency that causes the hypers to shatter, its weird.
