How hard it is on the motor? I have heard its harder on the motor than actually shooting that much during the pass? I know many people who do it including myself. I do it to make sure the nitrous is working.

Im refereing to trying each the nitrous system before a pass. I have a seerate purge and use it to get te air out I then try the nitorus. For example right after the burnout before you stage, take the car out of gear, rev t to 3500rpms or so and just hit the nitrous for a split second to test it. If you do this you will know what I mean.

 

Bang button ?

 

i do it every time i race, every one i know that runs nitrous does it. i have never herd anything bad about it. my buddys dad does it on his high 8 second car (high 8s on the bottle).

 

purge into the motor? I am curious as to why anybody would do that...isn't the whole point of purging to see when the nitrous is all the way to the solenoid? That's the reason I always purged atleast.

Maybe somebody can hook me up here. thanks guys.

 

Yea i also wonder why you would purge into the motor. Of coarse i dont know much about nitrous so maybe i'll learn something.

 

I guess I should re-word it. I think I will change to how many shoot there car right before making a pass to make sure everything is working. It also serves as a purge to an extent.

 

so like for me, i have a wot switch and 4000 rpm window switch. basically i would just leave it in neutral/park and hammer it so it will spray a bit?

 

i always do that when i first turn my system on, as long as you give it just a quick hit and let off before you hit the limiter you shouldn't have anything bad happen. purging just gets anything out of the line to the solenoid, so there is 3-4 feet or so of hose from the solenoid to the plate/maf kit or whatever you are using that hasn't been pressurized yet.

 

I had a buddy that would manually activate the WOT switch while holding the RPMS above 3k...he would push the WOT switch for like 2sec at a time, for maybe 3 times....worked just fine, im not suggesting for people to do it but it worked for him.

 

The reason you do is to clean the plugs off before a pass on those big boys that use -10 and -11 plugs. Most of the big nitrous boys do it for that reason. It will chuck and pop if they don't. I have seen a local racer around here hit his 1st stage just to get out of the water box. LOL........He then, after the burnout will hit the first stage by itself and then the second added on top and then the 3rd on top of that. It throws a ball of flame out everytime. Then he busts off a 4.7x in the 1/8 mile. Either way. you don't have to do it in your case. If you are scared your nitrous is not going to work everytime you spray it then you need to make sure eveything is right. I used to do it all the time. I don't anymore because I have a dry kit and it doesn't work like that. I also run NGK 10s in my car as well but James has it leaned out alot to keep the plugs in shape. I leave off of 275 and bring in another 225 in .8 seconds. No bucking or poping.

No buttom ends blown out around here from it. There are people around here hitting over 800 into their motors while in neutral. LOL

 

Thanks. Are you running progessive or just straight shots?

Everything is right on the car, I just like that little last piece of mind before racing. We pretty much grudge race only so its pretty important everything work all the time. I guess with electronics they could go out anytime though so just because it worked afew seconds before the race doesnt mean it will work. Atleast when you do shoot it before the pass you know everything is armed and the bottle is on.

 

I have been hanging out with some 10.5 guys lately and they do it. It sounded crazy at first but once they told me why and that it never hurt there stuff it seemed OK. I dont think I'll be doing it though.

 

Cools the runners and clears the motor out. I'd spray as it rolled out of the burnout, and then usually kept the kit armed and let it blip a few times as I cleared out the carb. No adverse affects.

 

Sounds like a bad idea to me. I'm new to nitrous though so I won't pretend to be an expert or anything.

 

i guarantee those people arent running composite intakes....or else the back half would be missing after the first backfire.

 

Not gonna hurt anything.

 

I have purged a few times into the motor while doing the burnout. For me, normally I just do a purge while pulling up and staging, and not into the motor.

i purge through my WOT seitch into the motor...during the burnout stall to like 1500 and stab it real quick then maybe blip it again thats it

 

I know this is a different type of motor and intake but a buddy of mine has a new Chevy Colorado with nitrous. He sprays while doing his burnouts since he doesn't have a purge. Well, the other day, he blew his intake apart purging into the motor. I wouldn't do it.

 

Why would it backfire. If it is done right it shouldn't ever be backfiring. BTW I motor purged tons of times right through my LS6 intake.

This is different. If you are spraying in your intake while in a burnout and then your tires hook it will blow the intake apart. I used to do it alot while in the burnout with a button. Gets your tires speed up really quick.
