Nitrous

Ieatcamaros · 06-29-2002, 10:20 PM

Hey guys, I am looking at adding a 75-100 shot of N2O this winter. I would like your opinions and suggestions.

First of all, what is the difference in a wet kit and a dry kit?

Secondly, my motor has 145k on it. I am probably going to rebuild it this winter also. But if I don't, is it a good idea to put nitrous on a motor with this many miles on it?

A wet kit is one that adds both nitrous and fuel to the intake manifold, a place where liquid fuel was never intended to be. A dry kit just adds the nitrous in the intake, and lets the injectors add the fuel. A wet kit is much more dangerous for the nitrous rookie because if anything goes wrong (valve float, valves incorrectly adjusted, timing off, etc.), you can have a very explosive situation. Your intake will now be full of a very flammable mixture when you use a wet kit. A dry kit never adds anything other than nitrous to the intake, and nitrous by itself is not flammable.

Take care,
-Chris

You should be fine with that many miles as long as you keep the shot to 75 horses. I'm adding a 75 shot to my car in a few days and its got just over 100k on it. From what I've heard the engine can almost always handle that small of a shot without a problem, its when you get into the 150+ range that people start complaining about broken engines. Plus with anything over 75, you should probably go to bigger injectors and fuel pump. With the 75 you should be okay by just retarting the timing some and putting in some colder plugs.

Oopps, I forgot about that part of the question!

Agent is pretty much correct, but it depends on what kind of condition your engine is in. Mileage isn't really relevant, it's condition that counts. Do a compression test, both wet and dry, and see what the difference is. The single most important factor in deciding if your engine can handle it is how good a seal your rings have.

Take care,

Ieatcamaros · 06-30-2002, 07:28 AM

Thanks guys. Will a 190 pump and 24#'s be enough for a 75 shot?

PKRWUD · 06-30-2002, 08:00 AM

Plenty!

tarmon8r · 07-01-2002, 11:29 AM

just make sure you have a good tune on your motor also. at 145k miles, some people don't keep their ride in a very good state of tune. ex. good plugs, wires, cap, rotor, coil. etc. you dont burn any oil or smoke during start up do ya? like the previous poster said, make sure your rings are good so you dont have any blow by and your valve seals are good. cause when you spray you dont want any oil in the cylinder that my cause pre-ignition or detontation.

Ieatcamaros · 07-01-2002, 05:21 PM

My motor ain't in the worst shape. I have to add about a half quart every 6-7 weeks of driving. But it is not that I am burning oil, both vavle covers are leaking. I just ain't fixed them yet. I am going to do what Chris said, check compression. If that checks out okay, then I am probably going to add that nitrous here real soon.

spray and pray, baby

good luck

The last time I said that, I had told my buddy that before he and his girlfriend went on a date. Of course, we were talking about him gettin some. It was actually about two weeks later, be got it on. He is a daddy now. So, I don't give those words as advice anymore. I wish I'd told him to jerk and squirt. That was pretty good though. It sounds good with nitrous.

tarmon8r · 07-01-2002, 09:15 PM

jerk and squirt

LOL

hehehehe

I run a two stage wet system on my Viper. My Mustang uses a Dry shot for intercooling. Just two different setups for two different reasons.

On the Viper, I am running 175HP shot on the WOT switch. I use it mainly in first gear once I squeeze out of the hole. Once shifted into second gear, I hit the second stage for another 200hp boost. So far I have never had any hiccups or scares. I can pull 142 mph in the quarter mile with radials.

On the Saleen, I am using a simple 25-50 shot jet, but on the dyno it really makes a 100hp difference because of its intercooling effect at high boost levels.

I do have to suggest you use a spark plug one to two heat ranges cooler, and possibly find a MSD nitrous retard controller or just retard your timing 1-2 degrees for best performance.

Best of Luck!!

Ieatcamaros · 07-02-2002, 04:13 PM

When you guys say retard timing a few degrees, are you saying retard from zero, or from the 14 degrees I am running now?

If I retard the timing to say, -2deg, then I would have retarded mustang. LOL!!

PKRWUD · 07-02-2002, 06:00 PM

Retard it from where you normally run it.

Take care,
