N2O not N20.

yes, anytime you are on a nhra sanctioned track... t/t or event does not matter

Yes, at any NHRA sanctioned track. You can prolly get away without one at Atco, but most likely not at E-Town, and definitely not at Island.

Is this a new rule? I don't recall any one mentioning it before....

If I were to go to the track and NOT run N20 what would I need to remove to not need a jacket? Sigh....

It was new for the 2006 season. I don't know for sure, but I would imagine that if you don't have a bottle in the car you wouldn't need the jacket.

Ok, thanks guys.

Just a random tangent here, I have never been a track before so bear with me, how intensive is the tech search?

Depends a lot on what track you go to and what your car looks / sounds like.

At Atco, they'll pretty much just ask if you have a helmet and let you race. E-town is a little more strict, and Island is known for following the rulebook pretty much to the letter.

englishtown will pop your hood.
island will ask you to pop your hood, and sometimes your hatch.

i KNOW it was a rule in 2008, i believe it was in 2007 as well, one of the nitrous guys, or one of the track employees on here would have more details

It applies to everything... If you have the bottle in the car even if your gonna do motor runs. You'd still have to have the jacket.

Etown is really lax... They'll just ask if you plan on running lower then 14.0 and send you on your way if you have a helmet, pretty much anything snell.

If you've never been to a track before, I would recommend going there... getting seat time in your car, before you think about strokers or bottles or anything else.

englishtown tends to ask cars that they arent used to seeing to pop their hoods, they have had too many bad experiences with guys bringing their p.o.s's without any battery tie downs

This is true. I guess its all what they look like too... This season is the first my white z went to the track, and never asked to pop the hood... yet, only asked "supercharger, turbo or nitrous" Go figure. Heh.

last time i was there with the t/a they were pretty picky.......but when i take the trailblazer they look at the helmet, throw the numbers on and say nice truck......lol

Passed that point a while ago. I am kinda interested in going to the track so I just want to figure out what I will be getting into.

Another question, if I use a window switch do I need a WOT switch?

Yes, it's a good idea. And of course don't forget a fuel pressure safety switch.

So I have to hit the WOT switch to have the solenoids open? And then the window switch just makes sure I stay in the rpm range I want to spray in?

The FPSS is a given. ;)

yes, wot to make the noids open.....(once you leave the line you will be wot anyway)

the window switch will save your motor if you miss a shift or spin off the line.... and prevent it from coming on too early and breaking traction.

the fpss will shut the system off if you have a drop in fuel pressure.

none of these are fool proof, but the combination of the three and proper jetting should let you safely run nitrous for a long time

Also with regards to where you place the nitrous bottle, be very careful. As you can see in this picture if allowed to bake in the sun, the result can be deadly.

Can I make WOT different than actual WOT?

You mean you want to spray at part throttle? Not a good plan, funky pulse flow will cause pooling and wreck atomization. That will lead to a lovely nitrous backfire that would basically ruin everything.

Think back to every truly epic nitrous explosion you have ever seen, 99% of them are the result of pooling.

Leave WOT = WOT to be safe. Unless your goal is to blow it up, then enjoy :)

first batch of pictures.......thats the purpose of a blow down tube......

second batch.......thats the purpose of a sfi bell housing holy crap that looks bad, link to a thread?

he forgot the picture of under the Jeep

Eh, that picture wasn't the message I was trying for.
Mike, heres the link, http://naxja.org/forum/showthread.php?t=981053

But what determines WOT, like if the computer says 6300 why can't I make it 6k? I don't see why I can't do that....

my wot switch was a actual micro switch that the pulley of the throttle body hit when it was fully open, it was not computer controlled....

the corvette and other drive by wire guys usually put it under the gas pedal.......

its not something you set up like a window switch
