making nitrous easier on the engine
 

ok......im still learning about nitrous, so please correct me if/where i am wrong about anything.



its been said that nitrous is harder on an engine than boost, because nitrous hits the engine all at once, unlike boost, which builds up.



is there some kind of controller that would spray nitrous progressivly, to make it much easier on the engine?

would it even help?



i read a little about the nitrous mastermind thing.........but im not sure if this thing helps.

my understanding, is that it increases the amount of nitrous with the rpm. but what happens if you race from a roll, and punch engine at say 4000rpm already? its still gonna hit the engine with a high amount of nitrous right?

help me out here.

It's true about nitrous "hitting hard" thing, but this only becomes an issue when running large amounts of nitrous (in the 300+hp range).

YMMV

first off, i love it when people say that nitrous is "harder" on an engine than a turbo or SC'er. it may seem that nitrous is a little more violent at first look when comparing n2o to FI, but in the long run, its the FI thats harder on a motor. think about it, a turbo or SC is always "on" so to speak, whereas n2o is only active when you want it to be. FI is CONSTANTLY putting more stress on the motor. when done correctly, nitrous is a very effective and reliable power adder.

as far as what your talking about, yes you can buy "progressive" controllers that will gradually increase the n2o as you accelerate. i personally wouldnt use one because i like to have as much control as i can over what im driving. as far as it being "easier" on the engine, doubtful. most people get them because of traction issues. they're great on the street as they will help control wheelspin and they're helpful at the track as well.

thanks guys

All I know is that I bolted my NX 150 shot kit on when my car had 52K. I just pulled my motor two weeks ago at 140K, I'll be honest when I say that I beat the hell out of that motor with more nitrous pulls than I can remember. The sad part was that the motor wouldn't die. With exception of maybe needing some new valve springs, the motor was running fine. I know a couple of blower guys whos motors didnt make it to 50K with getting the chugg of death. :death: Yeah their motors had stock internals but so did mine.

I used NOS PN 15834 programmable
nitrous controller. It will do just about any thing you want it to. Just be sure to use a extra nitrous solenoid (as in two)
and it wouldn't hurt to use an MSD start/retard box either. With 15834
you can bring in as much or as little nitrous as you want and over a period of up to 9.99 seconds.

Just dont spray below 3000 rpm and this sudden impact is dampened.
