upgraded fuel pump might help, are you an auto or 5spd?

Default Clutch Slip

I am running a "dry" ZEX system. I'm on my third bottle and, so far, Subie's engine seems to really like the extra kick. Her clutch, however, slipped with the .032 55 shot nitrous jet in. She has Cobb cams too. I got a .028 NOS jet, which of course didn't exactly fit until I modified the ZEX injector. I am using a ZEX .038 fuel jet. The .028 jet doesn't have the same kick as the .032 but it is a very nice extension of the power curve and the stock clutch is holding. I'm going to stay with this for a while. Fixing the clutch might just lead to the next weak point failing. I think ZEX should market a wider range of jets but they seem disinterested in service overall. Pretty short sighted in my opinion. Nitrous has a checkered reputation that I would think they'd be trying to overcome. For me, it is an excellent system. Relatively cheap equipment cost, some minor ongoing material cost, and totally bolt on/bolt off.

i'm not sure that anyone who could sucessfully hydrolock a motor needs to be playing with an oxidizer...but that's just my personal feeling

Your friend has stock injectors and 'stock' fuel pump right? Is your friend on the I-club? If so, what is your friends name on the I-club?

PLease dont mistake NOS with just any Nitrous system. That dam movie ruined the whole sport of sport compact cars. Please use the term Nitrous or n2o unless you are planning on getting a NOS system but they suck.
Now that ive vented and i take the stick out of my ass, i can coment on the topic...I run a 55 Zex shot in my car and have alot of fun with it. No where have i heard of it doing any damage to the motor unless you hook it up wrong.

Thank you

Stick with a computerized system like Zex or Venom and you'll be fine. Plenty of people run 75hp shots all day long with no ill effects.

I've heard in some places, like for one Washington state (King County) here, need a commercial licence of some type. However I'm not clearly sure about it since I'm not real fond of N20 applications.

Just a heads up info...

I don't know about the strict legality but my system is pretty stealth. You'd have to pop the hood to see anything. The bottle is under the bed of the wagon and the arming switch is in that little coin drawer low on the left. It would be easy to take most of the system out if needed for emissions testing. Although, you'd probably still pass - just don't activate the N2O. As far as lasting, a 10 lb bottle is only good for a few minutes worth of continuous use depending on shot size. But, I find I only use short bursts like 3 seconds. Now that the thrill is wearing off, I hope to get a month out of a bottle and still have reasonable fun.

well in NJ, you have to have a permit to carry it (which i have) but you cant legaly use it on the street. A full 10lb bottle will give you 3 minutes of time but i dont use for more then 15 secs at a time. Well actually 14.5 secs as opposed to 15.8 with out. Im dynoing next saterday so i'll post what kinda hp gains i get with it.

As for clutch slip, i think i kinda get a little but its good cause it'll give me a good reason to get a better one when it goes.

nitrous is NOT street legal, you need a hazmat license to carry it, that's why you don't put the bottle or solenoids in plain view of the public. The reason it's not street legal is because they have no way of telling if it's the Nitrous Oxide used in dental equipment(controlled susbstance, illegal to posses) or the N2O used for automotive/racing applications. you can have it on the street just don't be stupid about it and atrract attention to yourself and you'll be fine.

I ended up calling around Maryland before because a cop had responded to one of my posts at another sight about he better not catch me with nitrous in my car. Jeremy is right about you having to have a Hazmat sticker on your car but the condition what that if you exceeded a certain weight and/or size container of nitrous that you had to have a hazmat sticker visible.

You are fine taking it to and from the track or any place else as long as you do not have the nitrous 'readily available'. This means do not have it hooked up and ready to be used. That is illegal. Taking it to and from the track, from the store, or just transporting it in general IS legal.

Now mind you this was the case when I called for information in Maryland because I was going to go to M.I.R (Maryland International Raceway). It is entirely possible that the law has changed since then (late 1999) and that laws are different depending on the state/city/town you are in (like window tinting). I simply don't leave my nitrous hooked up (*cough*) if I am worried.

Now if you had a nitrous cylinder that refills nitrous bottles, then I think you would fall into the hazmat sticker territory. Just call around if you aren't sure but DNREC or the EPA in the town you plan on visiting may be able to help give you some clear answers. L8Rs

So is dental Nitrous Oxide and racing N2O different?

"Some confiscated "nitrouts" tanks actually contained other gases such as argon, automotive nitrous, etc. which are extremely dangerous. [There is an enormous difference between pharmeceutical nitrous oxide used by dentists and other nitrous compounds used, for example, in racing cars and boats.] "

From here.

I tried looking elsewhere as well for like 3 minutes or so and couldn't find exactly what the differences is between automotive nitrous and dental nitrous.

Nitrous oxide is nitrous oxide is N2O. Purity may vary between types of mix. Our NOS type nitrous can contain an irritant, sulfur dioxide (SO2) to discourage inhalation. I haven't noticed that in incidental exposures during line venting though. But, I'm not going to go sniffing for it either. Dentist nitrous won't hurt.
