I have an Auto C6 and want to use the WOT switch to turn the N20 on out of the hole.

Can this hurt my engine if I turn it on before 3k rpm on a 125shot 100 to the wheels NOS dry shot?

kit 5177.

Yes. I woudent do it. I have a 5177 kit w/ a window switch. Ive read never spray under 3k.......still trying to get my system to work, but i know this for sure.

Oh boy...here we go again.

FLC6 - My answer is absolutely not, but that's just my 2 cents. Take it FWIW.

You'll hear all kinds of babblers 'round these parts.

That was a wet kit. Puddle.

I would say that with a 100 rwhp shot you could spray just under 3000 rpms. I myself would probebly not spray lower than 2600 on that size shot. And I would definatley be using a window switch to remove the human factor.

Doubt there is any puddling between 1600 and 3000rpms! I say this with confidence as I have sprayed a few times from 1650rpms, 150 wet, out of the hole. Violent? Hell yes, not recommended, the torque spike is a killer, literally! No real benefit of spraying that low either.

Power Brake It And You Should Do Fine

I blew a head gasket on the 383 a while back hitting both stages at 3000 rpm..it was about a 300 shot. I did not have the race gas i needed at the time. The 300 shot at 3000 rpm would be about equal to a 150 shot at 1500 rpms.

what does powerbraking have anything to do with this?

Here's what i have done without a ws. Powebrake like suggested (stock converter) and using a little longer nirous line from noid to nozzle (poor mans ws). have this hooked upto a wot sw and bingo for a smaller shot. by power braking your up with your rpms where you want/like it and once to the floor your outa danger zone, but can still be under 3000rpm if you want. Used this many, many times. also, had shift points and rev limiter set for my needs. this was with a 5177.

Edit: I allways tried to keep mine around 3000rpm or a little higher, but like was said you can prob get away with a little lower on a smaller hit.

I sprayed a dry shot below 3000 rpms on my car all the time. I found out the best way for me to get out of the hole was to launch it and let it bog and as soon as it starts to bog drill it. The spray would hit and pull the car out of the bog and it would just shoot off. If it was timed right you couldnt even feel it bog, just felt like you took off. Now I would never try and spray a wet shot that low.

You can do it... the question is do you want to do it. From a longevity standpoint, you're better off to spray at a higher RPM on a stock bottom end motor to avoid the torque spike and high cylinder pressures. The added stress on the motor is cummulative and causes added fatigue on the rotating assembly. As with any mechanical device, the harder you use it the sooner it will reach the end of it's useful life.

On a side note... if you're gonna spray on sticky tires at the track, consider getting yourself a differential strut brace.

lol. Love that way of thinking. You can do it! Yeah! Never ask yourself if you want to. If you really take the time to answer that question in its entirety you will always say no (at least for a non dedicated race car). Do I want to spray 200 shot of dry nitrous tonight? Sure, then the guessing starts, what if:
- the fuel pump quits
- the plug gap is wrong
- noid sticks open
- too much timing
- too little fuel/ or octane
- the rearend is not ready for this kind of abuse all over again
- the trans slips
- and the list goes on.....

I will wear either my "pill it til you kill it" OR "Pimp Slap Mustangs" LS1Tech.com shirt tonight as I continue my jetting Internal Debate

Not below 3000 don't see a benefit. window switch I so happen to be selling one.

Race Car Driver

I spray my 346 auto with a 150 dry shot at 3200 thru 6600 rpm.

you're telling me. according to all these guys here, don't do it. meanwhile, i will keep turing it on at 2000 rpms. now, of course, mine are wet kits on both cars.

we could get into another 5 page thread about it. but overall, do what you want. make sure you are prepared for the outcome good and bad. the lower you hit it, the quicker you'll go. also, the more stress you put on the entire drivetrain of your vehicle.

Rob, did you notice a 60' decrease by spraying at 2000 as to the higher 3000 recommendation most shops give?
