Nitrous
 

I'm wondering what nitrous system works best on a non-massair 88 LX 5.0. Wet, Dry, system brand I'm lookin for 75-100 shot. How much can these stangs take. Lookin to by a used setup. Ideas? Thanks

When it comes to nitrous it doesnt matter if you have mass air or not.

A dry system is best because a 5.0 intake wasnt design for fuel to flow through it. A wet system is quite a bit more dangerous as far as nitrous backfires and such are concerned.

I wouldnt go over a 125 shot until you upgrade your fuel pump then you can go with a 150 shot.

Have fun,

So a 100 shot of dry should work on my stock fuel pump, cause thats what i'm looking at

Yep...That should work fine.

Thanks alot for your help

I never recommend Nitrous without adding a high flow fuel pump, reason being that the fuel pump degrades with age and abuse, Sooooooooo, unless your pump is brand new, I wouldn't try it, I mean how much more would it cost to add the pump?, you care about your motor I'm sure, do it right, make sure you got enough gas BEFORE you add Nitrous...........

get a inline pump from MSD yes MSD they make a EFI inline pump and its liek $75 and supporots over 500 horse and get a nitrous express nitrous in a bag its like $349 and installs in less than 1 hour

pump
 

You must get the high flow in tank pump FIRST, at 100 horse spray level that will be fine, any more, then get the inline..........

get the plate system from NOS. Its bad *****. Its a wet system, without the problems accociated with them due to fuel being introduced into the lower manifold only. and you get a free intake spacer to boot...:)

If you are serious about using nitrous, then get a plate system. Anything else you are asking for trouble. Also, a stock (88lph) pump will not suffice for a 100 shot, you will go lean and burn piston(s). When dealing with Nitrous, your motor gets its power from the extra fuel NOT the nitrous. Nitrous only helps to facilitate the burn of the extra fuel. What I mean is, Nitrous breaks down chemically at roughly 550 degrees f, which releases the base elements of Nitrogen and Oxygen into the combustion chamber. More Oxygen+more fuel=more power. Nitrous without the extra fuel... Well, (extreme lean) temps inside the combustion chamber will spike dramatically causing a whole host of bad things to happen to your internals. Yes, it's the best bang for your buck. However, if you don't set it up right all you will get is a bang and spend alot more bucks. Sorry, that phrase way lame but I had to say it!

A 100 shot is a breeze for the stock fuel system. I sprayed mine for a good while.

I called NOS when I bought my kit and they said "go for it"

I'm gonna be installing the NOS 5115 dry kit in my car soon and run about a 100hp but have a stock fuel system, I have a brand new replacment fuel pump installed and gonna install brand new 19# injecotors so i'll keep you posted as to how it works out.

NOS also advised me that the stock fuel system was sufficient on thier "big shot" plate sytem, which shoots a 150 HP shot.

The benefits of a wet system is that your smaller injectors can do the job, as they arent tasked with adding the extra fuel

well i'm only gonna be spraying at the track and thats only gonna be maybe a few times a year so I was hoping on my dry system the stock pump and injectors would be fine for that with the extra 100hp kick in the ***

Do yourself a favor and run on slicks. Street tires are a bad idea for drag racing especially when spraying nitrous.

Good luck,

Actually, guys, a direct port fogger setup "works best" LOL :p ...but it's a bit more involved than the more common 'bolt-on' systems that the aftermarket is literally flooded with these days.

I started w/ an NX single nozzle wet kit (50->150hp) in '98 and the only problem I ever encountered was the one time I bounced off the rev-limiter on stock rubber in 1st gear with a 150hp shot. ;) That started my learning curve w/ nitrous....

Last year I ran a single nozzle (mounted in the TB) NX EFI Race kit (100->250hp) jetted @ 200hp and never had any 'fuel puddling' issues. As long as the system is tuned properly, you won't have any problems. It's when you start running the system excessively rich or lean is where the problems start.

If you want to 'plug and play' then I'd recommend the ZEX dry kit, as it's the safest kit available, that I'm aware of. It adjusts fuel delivery according to bottle pressure. That is one aspect of nitrous tuning that most beginners overlook.... maintaining the proper bottle pressure is critical to a 'good tune' and safe power.

As far as fuel systems go, the majority of the entry level nitrous kits are designed w/ the stock fuel system in mind (and stock motor as well). If you have modified the motor w/ induction/exhaust components, then you should consider upgrading the fuel pump to create a margin of safety. An adj. fuel pressure regulator is a good idea, or at the very least a good fuel pressure gauge that can be monitored while going down the track. It's the supporting components that are sold separately that make a basic nitrous system consistent and reliable.... bottle heater, nitrous and fuel pressure gauges, MSD window switch, etc., allow you to have the best experience while using nitrous oxide. ;) It's all the little stuff! :)

HAHA thats what they all say!:p

I said it too, and kept my word for about ummmmm 2 hours:D

You are taking a big risk with your motor. The 88lph pump can BARELY support 300 HP on it's best day, especially with the 19#er's
NOS's "Big Shot" uses the factory schrader valve (87-93) to supply the extra fuel to the engine. 200 shot and above you must get an in-line adapter to the main fuel supply to be safe, according to NOS. The schrader valve (87-93) is to small to support anything larger than a 150 shot, according to NOS. If you want to do it right, get a bigger fuel pump. Running rich never hurt anything but ET's...running lean..with juice..will get you Cherynoble. Anyway, it's your motor, you do whatever you want with it. My advice is, don't believe everything you hear. Do the research. Mistakes cost lots of money. Juice is lots of fun just don't get to greedy.

about how long does a 10 lb bottle last, spraying a 75 shot?

nitrous
 

With only a 75hp shot...I'd guess around 15-20 full 1/4 mile runs.
