What kind of setups are they running? I was watching them run last weekend and they would purge for over a minute sometimes. What kind of bottle pressure where they at and what psi do they run at? Im guessing they purged for so long to get there bottle pressure to a certain psi. Also how many bottles do they run normally, they have to have more than one?

I'd love to know at what point do they run two bottles.

We use SpeedTek. And several more do but they use 3 stages and we only have 2.

As to the tune.... ask 5 people (the same question) and you'll get 6 answers!

It 's good to run two bottles at any point, helps with the pressure drop, I've heard as many as 5 stages, with some turned off on the top end to save on parts

most of the top guys have the ability to run 4 stages. Your correct on why they purged so long. As far as bottle pressure goes, most wont come right out and say

miny you can see on paco's, its got two foggers on the outside, one on the inside, and a lot of guys have one that runs through the center of the plenum.

What kind of psi do they run? They have to almost drain a bottle purging for a min.

Most are running 950-1000 with 2 10lbs bottles. Alot of them pump alot of heat into the bottles at the trailer so if they sit in the lanes along time they dont have to use a torch.

i love some peoples reaction when they see someone for the first time heating a bottle with a torch. hahaha

The torch is illegal at all NHRA tracks and it scares the **** out of me. I have seen the effects.

Pressure drop is the main reason. On my true 10.5 small block car we leave the pits with one full 10 lb bottle at 1250 psi and purge down to anywhere from 1000-1075 at the line depending on track conditions and weather.

Anyone who uses a torch on a nitrous bottle may as well be playing Russian roulette, they are a dumb ***.

A guy here locally was killed doing it, they picked his body parts out of the rafters of his shop. And no, that is NOT an exaggeration.

Agreed, that story spread like wildfire...

I might be getting that story confused, but I heard a long time ago that somebody blew a bottle up at the track in Mobile? I dont know, could have been the same story with a twist....

It makes me nervous when I see someone using a torch...I try to get out of dodge!

Im just saying that if you are going to do it to at least move it around and live a little longer hahaha DON'T DO IT.

Would I ever touch a bottle with a torch? NO WAY! Heating up metal like that changes its caracteristics, in other words you are playing with fire in more ways that one, get it to 1,000 PSI and the bottle blows with 1,000 PSI and yep they will be picking your peices up.

I know of a local 737-200 at a local aircraft maintenance school that has the oxygen bottle blew in it (like a 20ish pound bottle) because the tech did not clean the grease off of his tools, now smart people soak their tools in isopropal alcohol before changing a bottle and put on new gloves on top of soaking and cleaning all the fittings REALLY well. It blew a hole so big in the aircraft that you could walk threw it. Nitrous would not be any different if the bottle blew.

You still have the idiots in their trailers hiding..........

99% of the people here use a torch to heat there bottle's since most tracks don't have tech. Even at the ORSCA last weekend I saw some cars in the staging lines using torches. IMO if you move the torch around enough and stay away from the neck then you should be fine. IF you heat it to fast or hold the torch in one spot I could easily see that being dangerous.

Every track I have ever heard of has tech????????? Not sure how it could be an NHRA or IHRA track and not have it.

Using a torch is still much more dangerous then a heater, even if you move it around its still applying the heat in a more concentrated area then what a bottle heater does. Near the neck or away from it does not matter that much.


Just not safe period. If I saw a someone doing it in the staging lanes I would turn them in in a heart beat, not gonna get myself killed or shrapnell in my car.

Around here if your class does not allow a bottle heater they will kick out out for using a bottle heater that rigged up in your trailor........

You need to go to more 1/8 mile tracks in the sticks. Most of them could care less about NHRA/IHRA sanctioning.

I've used a torch in the past, but for my own use, I'll only use a push system. The only heat I'll use on a bottle is to put it on the floorboard of a vehicle, drape a coat off the glovebox and turn the floor vents on. 10-15 minutes and you've got at least 1000# of pressure. This comes in pretty handy on the street if you don't have a heating pad.

Yeah I have heard the tracks down there are a little more laxed.

I saw a guy once lay the bottle from the valve cover to the strut tower and it pretty much acted like a bottle heater and the heat coming up from the header warmed it like a bottle heater. WOrked pretty good.
