Questions about N2O and exhaust

[lone_wolf025]

Been searching around and I've gotten a lot of info but still haven't found the answers I want. I'm looking into going into a nitrous setup. I've found lots of info but I want to know what are the disadvantages to it like say limits or worst case scenarios all the way down to the "Oh no I've been pulled over. What'll happen?" For clarification I'm considering starting with a 75hp wet shot. I will be getting a 2.5" exhaust to compliment it all.

I'm also wondering about the benefits of keeping a hi-flow cat or just running without one (currently I have the stock cat but I'm looking to change that.) I have read that technically you can't have your cat removed unless the car is 5yrs old or has 50k miles due to federal law. Anyone else heard of that?

Any info would be appreciated.

IL has a whole different set of laws for CATS. Here in TX, before a certain year you don't need one. I think its '72. After that you are required to have one on your vehicle while running on state and public roadways. Some cities like Houston enforce this law very hard, due to smog and other polutants.

The Hi-Flow cat, is a good thing to get for the exhaust, honestly there isnt that much of an increase from Hi-Flow to Test Pipe, maybe 1-2 HP gain if that. Though the research I've seen has been on a 4 banger. If you are going for NOS, the best bet on a CAT would be a metal, rather than the ceramic. Metal will hold up to the heat better, and will be better for the high A/F ration for NOS.

I also have the question on what is a better NOS system for the GA. And was is the max SHOT you can give it without grenading the engine.

I have heard that if you are going to run stock internals 75 is the maximum safe shot you can run. I dont know for sure thats just what I have heard.

[lone_wolf025]

I've heard 75 too. That's the most common number I've found in searching through the site. Though I also heard 100 from a few as well. Personally I think I'd stick to 75 and go from there.

I would go higher than a 50 wet on stock internals.......

[timberwoof]

So if the heads were stage 2 and mani's ported would it be possible to go higher, or would you recommend doing the crank, rods and pistOns.

[99Alero_Boy]

crank would be fine for a long time, rods and pistons are really up to the user, i would abuse the nitrous bad so that is definatley why i am getting forged pistons and custom rods.........

good point

"Oh no I've been pulled over. What'll happen?"

Bottle should be in the trunk anyways, so i dont see why that would be a problem.

[timberwoof]

The bottle wouldn't matter as long as its closed and disconnected.

But you're screwed if the COP knows what hes looking for.... Like me

Yea umm remind me to have that tightly folded $100 bill taped to the back of my license if I'm ever in your area :D

[timberwoof]

Sweet, easy money. I don't know that much about cars, but I'm learning a lot more reading. In the past two years I can tell you I've gone from knowing absolutely nothing to being able to distinguish a part off certain cars just by looking at the part.

[lastyear4gt]

Why does it have to be disconnected, as long as its closed should be OK. If thats the case all you do is buy one of those remote bottle openers.

[lone_wolf025]

The reason I ask in the first place is that I once heard that if you were pulled over and they decided to search your vehicle you could get slapped with reckless endangerment or something like that.

werd. And if they're searching your car, i would assume that you have more worries than an open nitrous bottle :)

[timberwoof]

Sorry guys, I didn't mean to put the "and" in there and confuse everbody, i mean to put "or". And it doesn't even have to be the bottle disconnected, it can be the line. As long as the system is not connected to the engine for use or as long as the bottle is closed, you can have the nitrous. Atleast that is how it is in Texas.

oh and the search deal. If an officer has probable cause to search your vehicle, he won't ask permission. But if he ask permission either he is trying to see if you are being deceiving, or if he might need a K-9 on scene.

I know that more Police here in Texas will not get you for every little detail on your car. Loud Exhaust over 98db, tint, vehicle height, lighting displays, and so on. But they are reasons for pulling you over. Now Cali on the other hand, if you have a street runner, good luck. The troopers around here, some are strict about these laws, especially "weights and measures" but they have the truck to carry all the tools to test everything. Most patrol cars don't have enough room to carry certain equipment so the officers don't bother them, and most of the time they just need a reason to stop you and search you for dope. HEHE so next time you're out rollin don't be "ridin dirty"

[el nino]

what kind of setup are you looking to get?

[lone_wolf025]

If you're refering to me I'm still in the planning stages. But from what I've read and learned I was thinking of a 50-75hp wet shot. In terms of brands I'm still researching. For now it depends on what I can get away with on the stock internals w/out abusing it too bad. I could go dry but knowing me I'd probably like to upgrade and go larger w/out having to purchase a whole new system, and also I like the fuel delivery aspects of wet better than dry.

"wetter is better"

haha. I couldnt have nos, id use it way to much. My personal favorite quote on NOs... "Nitrous is like a hot blonde with an STD, you want to hit it...but you're afraid of the consequences."

Heh I like that analogy. But then again it will be sometime before I actually have the cash to get it so I may change my mind by then. I don't think so but ya never know.

[el nino]

regarding Nitrous i ran across this on the web "If you like nitrous you will need to have the factory head bolts removed and new bolts installed. (If this is not done you can and often will bolt the head right off the motor.)" would this apply to only ppl who are shooting too high?

[AaronGTR]

That's some very vague and misleading advice. If you use too much nitrous on a car with a weak motor or known for blowing head gaskets, then yes it is a possibility. If you use too much nitrous without properly tuning fuel and ignition timing, yes it is a possibility. Overall though most people do not have to change head bolts in order to use nitrous.

[Shaun41178]

wait a sec. Aaron didnt' spout off bad info? Mark this day. Its a first.

[atc3434]

The 3400 will take properly setup nitrous in the amt of like a 100shot a lot longer than the tranny will. Properly tuned, there is no reason spary a 100shot should be a major concern. Of course you'll wear the motor faster, but if its setup well, it won't be unsafe for the motor.
