What's the best kit for a 99/01 cobra?
-there's really no set answer to that its all in personal likings/opinions, the available options i believe are NX, ZEX, NOS, Compucar, and a few other small companies that takes from the larger companies and put their name on it. I personally run NX, and coming from NOS brand, I strongly believe that NX is far more superior.
How much of a shot can I spray on my stock cobra?
-untuned? i'd say a 100 shot, however the car will not run to its full potential with the nitrous, yes it would be faster, but not as fast as it should be on the bottle. once you get a tune and a general knowledge of how to drive your car on nitrous there is no reason your car should not take a 150 shot with the stock motor.
What do I have to do before I hook up my system and spray?
-Fuel system, if you plan on just running a 100 shot or less and having a little fun every now and then, you can get by with just changing the fuel filter, once you get up to start spraying in the 150+ shot range i recommend upgrading your pump, the easiest pumps that actually works to install on the returnless style system are the Focus pump, or Aviator the focus pump should be sufficient, but you can always go to the bigger Aviator pump, and have it tuned in, I personally run a Walboro 255lph pump and can't be more satisfied, but there are a few modifications that have to be done to the fuel basket to run the Walboro. Spark Plugs, 1 to 2 heat ranges colder, I use NGK TR6's which is about 1 heat range colder... for the guys that are more safety oriented, I'd also recommend an MSD Digital RPM Activated switch (aka window switch) this allows the nitrous to shut down in the event of an over-rev or you happen to attempt to spray too low, therefore preventing a backfire. also a Fuel Pressure Safety Switch (FPSS) when your fuel pressure drops, this safety switch shuts down the system as well. Other optional items include- Bottle Warmer, it keeps the nitrous at a perfect pressure, making your car more consistant with nitrous. Blow Down Tube, in the event of too much pressure you can vent the nitrous out of the car when the valve pops, if you run nitrous at the track they look for this (this can be bypass by installing a sheet metal "firewall" across the back of your back seat, thats what i use, and it must be AT LEAST .032" thick. Also for activation I recommend a WOT switch, much more easier than messing around with a button, a WOT switch is basically a switch you position on your throttle body that activates the system once the blade on the throttle is completely opened.
What's good bottle pressure?
-I believe that perfect bottle pressure is 1050psi, thats what i try and maintain, anything below 900 psi is getting too low, and above 1200 your solenoids will freeze
What's good nitrous gears on a 4v?
-Of Course 4.10's/4.30's, that will put you in the powerband quickly and keep you there when you shift, the general idea for spraying a stock 99/01 4v is from 4k-6800 rpms, however stock 3.27's will work fine
So I bought nitrous, I'm spraying and i hear "POP" and my hood looked like it lifted, what do I do?
-Shut your car off! IMMEDIATELY!!! you just experienced a nitrous backfire, most backfires occur from too much timing, not enough RPM, too much RPM, or spraying while not at WOT, if you're lucky the only thing that will happen is your intake shatters into peices everywhere, however i still recommend doing an engine overhaul after a backfire, there could be metal in your cylinders, or heads which may cause a problem in the future, i've heard of people just cleaning up the heads, and buying a new intake manifold and slapping it back on and running the car again, that's just plain retarded, some people don't even clean the heads they just slap on a new intake, again thats dumb...... do it the right way, pull the motor disassemble it, and overhaul it, you never know you could've blown a hole in your piston or bent a connecting rod.
So all of this talk how exactly do I spray nitrous?
-It's simple after you have everything hooked up and ready to go, take your car out to a safe and secluded location (preferably a drag strip) leave normally, and roll through the RPMS gradually and just before you 4k or so RPMS, nail the pedal to the floor, you should feel a difference, i recommend doing this in second or third gear your first time out, and practice practice practice, i started out that way in a higher gear, now i launch on spray, its just like learning to drive a car for the first time, you're not going to jump right in and be perfect.
I've heard of people saying "Nitrous blew up my motor, or Nitrous will damage your motor" is this true?
-This is the time when you bitch-slap this person, Nitrous does not blow motors, a bad tune, or untuned set-up, the user, getting greedy with nitrous (running too much) knowing your stock motor can not tke a 300 shot. the list can go on but i'm hoping you get the point. When properly tuned nitrous is as safe as any other power adder.
How long should my stock engine last while spraying a 150 shot?
- :shrug: <-- thats the best answer, like anything else in high performance its a gamble, it could last for years, or it could blow the first time you spray the motor.
What does a purge kit do?
-It does exactly what the name is, it purges air and/or debris from the lines and on NX kits if its setup properly it purges the nitrous solenoid as well, what i use the purge for mainly is to get the perfect bottle pressure, if its too high. i mainly see most people on the street use the purge as a "ooooh ahhhh" thing and waste perfectly good nitrous.... i guess its supposed to be intimidating
Where can I purchase a kit?
-where to purchase a new kit is all up to you, however when you buy a used kit, I would definately stay away from peiced together kits (i.e. different brands or systems put together) also if you don't have the instructions or a general knowledge of how relay works, i'd let some who knows how, to help you out, i've seen people hook up nitrous kits and their damn solenoid open up as soon as they arm the system, ask ask ask, but be careful who you ask i've also spoke with some nitrous "kings" about the system and thought to myself "what an idiot"
Last but not least if you want to run nitrous in my opinion its a pretty fun power adder, i've ran several different power adder set-ups on multiple cars and i think nitrous is the best by far, its consistant, cheap, and very easy to trouble shoot.... and addicting
*there's more im sure i left out if anyone wants to add*
