nitrous questions... little confused.

zkiller18 · Aug 16, 2004

hey guys.... i am looking into nitrous now. i was told that a dry kit would be better because it doesnt spray fuel into the manifold, with a wet kit i was told that it could backfire and destroy my manifold. but on the other hand i was told i couldnt use a dry kit either because of the returnless fuel system... what should i do. also what system would you guys suggest and what mods do i need to prepare for the nitrous? thanx guys.

anyone?

I had a NOS "DRY" kit. I got awesome results.

If I was to do it again, I'd go direct port.

If your staying with the stock motor, I'd (for you) use a "wet" 100 shot and be done. I don't really care to spray much more than that through the intake (fuel wise), it was only desig. to flow air.

NOS makes a dry kit for the returnless fuel system in the '99 and newer GTs. You can even try their direct port NOSzel kit. I hear that one is great and it comes with a WOT switch and a RPM window switch and a couple of other cool safety features.

For what that kit costs, your almost a 1/3 of the way to the cost of a blower! Keep saving!

where is a good place to order a dry kit from? and is it necessary to get it tuned if im going witha 75 shot?

Yeah but it comes with a window switch, a WOT switch, a fuel shut off, so if pressure drops below what ever psi it kills the N2O. You could buy a regular dry kit and after you get all these safety features that dont come with it you'll end up spending the same amount. Zex has a cool self contained unit as well, but i think it only a 75 shot. NX has really good stuff too, just something to think about.

i was thinking of only putting a 75 shot on my car.... just a little extra punch for people who like to talk crap. i want a simple kit i dont want lines a solinoids everywhere.

nitrous

with a 75 shot you should be fine!

The only part of a "dry" kit i didn't like was you can't adjust the amount of fuel being added. It uses a preset amount.

When I was using a 100-125 shot my AF was in the high 9's low 10's. This is still WAY too fat. I had to go up in the 150-175 range to get into the low 11's. Being to rich can hurt a motor just like (not quite) the same as going too lean.

if you get the zexs dry kit you can shoot up to a 125 shot it comes with all the nozzles! and they have a good system!

This is true the "Jets" sizes will determine the amount of hp to expect from that kit. I try both dry and wet. My dry set up was NOS in my Automatic 99 GT, the bad thing is that dry is limited to 150shot. The wet (NX) is great way better than my dry, but theirs always the problem with the Freaking plastic intake. I just sold my wet, and next up is going to be a Noszle set up from NOS

I have the NOS Dry Kit on my 01 and I am very pleased. I think Jeg's sells it for around 600.00 and it includes a WOT switch, RPM window switch, Fuel pressure safety switch, bottle etc. I am running a 100 shot and have not had any problems. I don't think a tune would be necessary with 100 shot or less.

LS2 KLR · Aug 17, 2004

I use to run the Edelbrock dry kit for a couple of years on my stock shortblock making 378/422. You will need a tune so they can add fuel through your injectors. I'd suggest a flip chip so you can have an NA tune for cruising. I then bought the NOS nozzle kit but was told it wasn't good for street cars due to its sensative tuning so I took off the solenoids and made a single nozzle wet kit. No matter what, get a dyno tune!!!

zkiller18 · Aug 17, 2004

thanx for your help guys. if anyone else has anything speak up.

in my opinion i would get a wet kit. i run nothing but 5.0's so i dont know if it would be the same as a 4.6 but, dry kits over work your injectors. with a wet kit that puts in more fuel you dont have to worry about this. Zex is a good kit, safe and reliable. but if your looking at making some power get a NX kit. by far one of the best kits on the market. i just got done putting a 100 shot on my 91 GT convertible. it is an awesome kit. makes some of the best numbers. with a ZEX kit, even though it is rated at a 125 shot it will only put down 80-90 HP. the NX 100 shot will put down 90-95. very efficient and the soleniods are the best on the market. get the NX with a window switch, WOT switch, and a fuel pressure safety switch and you wont have to worry about a thing. NX ALL THE WAY!!!!!

Here are my thoughts. First, though you CAN use a dry kit on a stang:

DRY N02:
Pros - Avoids pooling of fuel and potential backfire. Lots of interesting technology. Some systems will read your 02 sensors for A/F and adjust accordingly and others can determine exactly how much nitrous you are adding and add the appropriate amount of fuel. There are many safe dry kits that have sound theory behind them. Most are very effective with stock fuel systems up to 125 shot.

Cons - Kits can be complicated to install. They involve too many sensors and inputs. Systems that read 02 sensors don't have any way of knowing what is going on at each indivdual fuel injector. Kits are "conservative" as they continuosly make adjustments, therefore, a 100 wet shot will net you more hp than a 100 shot dry kit.

WET N02:
Pros - Simple and effective. Biggest possible bang for the buck. Can be very safe if all the appropriate safety devices are used (window switch, fuel regulator etc...)

Cons - Pooling of fuel resulting in backfires (avoidable if window switch is used).

If I were to go with a nitrous kit, I would probably use NX EFI Wet, 100 shot, with all the appropriate safety devices minus the remote bottle opener.

Either way, figure to spend (for new) $400 to $1500 max. You can get a really nice, effective, safe system for $1,000.

Nitrous is not very streetable, though. Great for racing, but you really should have a "flip-chip" with a nitrous tune that you can switch back and forth between especially is using on the street.

Also, the juice cost money. A 10 lb bottle might get you 8 - 10 blasts, that's about $3.00 per use. A supercharger or turbo is much more streetable and most likely cheaper in the long run with less worries.

But, there is a certain thrill beghind no2 that a blower does not afford.
