NOS at highway speed?? Hi Everybody,
Im a newbie so please excuse me if my question is dumb. I am interested in a dry Nitrous setup but not for 1/4 mile times. Im interested in engaging it at highway speeds - would that work? Im hoping that it would mean less stress on my clutch and soforth, is that correct also? I would assume it would cause less stress on my car if I was already moving vs launching for a 1/4 mile run.
Thanks in advance!

Re: NOS at highway speed?? It will be fine. Just be sure to follow all the basic rules when using nitrous. Do that and it doesnt matter when you hit it. The only cautions I will repeat that may be more imoprtant at highway speeds are dont hit it too low (3000rpm) and dont spray for too long of a time period and never in sixth gear.
Can anyone else think of other items that may apply?

Re: NOS at highway speed?? I dont reccomend using it on the higway. But if you must here is my best idea for engine safety:
Spray only above 3000 rpm to 5800 rpm...like what the other guy said.
Never spray for more then 15 seconds max! Any longer and your pistons are melting. That is more then I would even spray it with stock pistons. NOS said no more then 15, heck I say no more then 13 tops!
Can't stress this enough....forget about nitrous for spraying on the highway. Get a blower, or do some head/cam work. Your just gonna BBQ your pistons.

Re: NOS at highway speed?? I have sprayed on the highway and spun my stock tires in third gear with a 100HP shot. Like they said before, it does hurt anything. Just keep the bursts short and avoid overdriven gears. There is nothing like pulling away from a rice-burner at 70mph like he was standing still. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I have sprayed it for probably about 14 seconds before (starting from a stop) and my pistons looked fine.
Has anyone ever tried a EGT?

Re: NOS at highway speed?? Hmm.. I dont like the sound of fried pistons..
Think ill skip the NOS and put the money towards the motor or a turbo/supercharger. I have a 2002 Z28.
Thanks for the advice guys.

Re: NOS at highway speed?? man...do it you will never spray for more than5-10 seconds on the hwy anyway. Never even close to hurt anything with a stock motor and a dry kit. Use all the safeties(fuel pressure switch, window switch) stay around 100hp and get a good bottle heater. YOU WILL LOVE IT!! I wouldnt ever spray in 5 or 6th but you would be going over 130mph or so if you did. I am sure you usually roll from 50-60 up to 110-115 as if racing 1/4..maybe a little more. ITS SAFE!!! DO IT AND HAVE FUN.

Re: NOS at highway speed?? why exactly would a 100shot of nitrous melt a piston if used over 15sec and a blower giving you 100hp not? as long as you keep your rpms up and the fuel flowing i would bet my engine that you could dump a 20lb bottle in there all in one long shot.
i am no expert but here are a few things that i have learned on this board. nitrous cools the intake charge, a blower heats the intake charge. with nitrous if you make 100hp you get 100hp, with a blower you need to make more than 100hp to get 100hp because you have to run the blower.

The only difference I see with nitrous is the application is non linear like a supercharger. Hitting in in a high gear like 5th at too low of an RPM for too long is a problem. Think about the nitrous flow VS engine RPM. If your spraying a 150 shot...its a constant 150 wether your at 3000 rpm or 6000 rpm. Obviously the cylinder pressure and Tq will be sky high in the lower rpms. It would be the equivilant of a supercharger giving 20 lbs of boost at 3000 rpm and tapering off to 10 lbs at 6000. This is why I am going with some type of progressive controller soon. Actually I am really liking the Venom system. It does everything to mimic a naturally aspirated power curve....just higher.
