I'm pretty sure a fire extigusher bottle cannot hold the 900-1100 psi that will be in the bottle, you can find a used bottle for 50-75 dollars and then go with your kit from there.

Re: DIY Nitrous kit guru's thread
 

nitrous isn't something to be done cheaply in my opinion. spend a couple hundred bucks and get a real kit. i've seen/heard of too many freak accident's and explosions related to nitrous to skimp out on it. is your car really not going to be done until 2k9 ??? if not, just save .50 cents a day and you'll have plent for a bangin n2o set up by the time your car is ready to move on it's own power :)

Re: DIY Nitrous kit guru's thread
 

Oh jesus. The first link listed (the DIY nitrous guy) says anything that carries co2 can be used for nitrous. We're talking welding tanks, fire extinguishers, soda carbonation bottles, ect.... Ghetto D has made his own kit before, and it wasn't the 75 dollar bottle.

We rarely have a nitrous thread, lets just fill one up with info instead of arguing about who's smarter.



Where's whitey? ::)

Re: DIY Nitrous kit guru's thread
 

lol I just seen this thread. If your going to build your own kit don't model it out of the gay barney box zex kit. If your going to do a Nitrous kit than you need to get a wet kit, dry kits are gay. Also get a real bottle so you'll be able to pass tech.

Son, I don't know exactly what what I'm getting for sure. Give some tips on putting some ---- together so when someone asks how to do it we can tell them "search noob".


What's wrong with the zex kit? I like the fact that it's self controlling. I know there's ways to do this on your own, but I haven't figured it all out yet.

Since everyone loves pictures its my awesomeness of a nitrous kit:

Attachment 38439

Attachment 38440



-NX direct port kit 100 shot
-NOS purge valve
-Crane Cam ignition retard activated by nitrous solenoids
-2 10lb bottles

Re: DIY Nitrous kit guru's thread
 

The "self controlling" is hype. To me its just a glorified dry nitrous kit that uses a fuel pressure saftey switch that NOS offered for years. You need a wet kit to be safe especially if your spraying on top of boost.

Re: DIY Nitrous kit guru's thread
 

The think I've never understood about the fuel solenoid is that for the given fuel jet, there is a fuel pressure that the kit should work at. So you put the solenoid in front of your stock fuel pressure regulator, but how do you regulate the fuel pressure to the solenoid, and how do you keep it constant through the rpm range. The consistancy of the fuel pressure to the fuel solenoid is one of the things I can't figure out.

Re: DIY Nitrous kit guru's thread
 

the stock fpr is a 1:1 so essentially all it does is put a bunch of pressure ontop of the fpr so it addes fuel.. I noticed when using the zex kit that my fp went up to about 75-80 psi (just free reving with n2o line out of the intake.)

Re: DIY Nitrous kit guru's thread
 

No, but what I'm saying is that you have a "pretty much" set psi of nitrous flow to a given jet size = same amount of nitrous through whole rpm range.

Now on the fuel solenoid you'll have a set jet size, but how do you control the fuel pressure going to that solenoid to match the "same amount of nitrous at all rpms" with fuel at the same flow at all rpms unless you can control exactly how much fuel pressure the fuel solenoid is seeing at all times?
