Ok, how about a Nitrous for Noobs thread? I would like to hear about best products, best practices, wet vs. dry, gotchas and no-nos for nitrous on a 3.8L?

Surely some of you here are sprayed, so come share your experience on what works and what should be avoided.

Thanks -- we all should benefit.

Ok, I will start, Maryland Speed advertises this Nitrous Express kit for V6 Camaros:

LMPerformance has a similar Nitrous Express kit:
http://www.LMPerformance.com/3070/13.html

Can anyone critique why this kit might be good or not, and what, if any supporting engine mods should be done to support such a kit?

 

You saw the one in "Nitrous, Super Chargers, & Turbos" section?

 

I prefer bottle rockets taped to the rear bumper cover!

 

Yea, I'm going through Z28Pete's links there, but my preference would be to focus on kits and what needs to be added to them -- more or less plug 'n play...

 

Here is another one.

I have done some other research and the "kits" are just a starting point. I know for my car adding a clutch cutout and and "window" switch (2500-5500 RPMs) better injectors and a better fuel pump seems to be the minimum I need to add to the kit. Again, I think, this Dry kit spray the NO2 into the cold air intake that way it cools the MAF sensor which cause the engine to richen up.

 

^ Gorn, I assume you're talking about your 3.8L '96? I would love to get the details nailed for a 3.8L and assume one of the kits above in this thread. Maybe one of us can do a nice write-up for others to follow.

That Maryland Speed Nitrous Express Kit says "These systems require no engine modifications, operate on stock fuel pumps, and require no timing retards." -- so why do you think your 3.8L needs additional changes?

Are you saying you think the dry is ideal? It seems the wet is most ideal, but when to choose one over the other -- I'm still doing my research...


Here's a nice FAQ, one point worth noticing:
"Q. Is a nitrous system worth the money (horsepower per dollar wise)?
A. No other devise in the world offers such a bargain as nitrous oxide."

http://www.nitrousexpress.com/faq.php

So as much as I never was interested in nitrous, it seems like a good option, especially for V6 Camaros, since super/turbo charger options do not seem to exist unless very custom... The biggest downside to NO2 seems to be just the need to always refill, just like gasoline, as opposed to a SC/TC...

Also:
"Q. Will I need anything else to install the kit properly?
A. To complete the installation a Gen-X package should be ordered with the system. This includes the bottle heater, liquid filled nitrous pressure gauge, low fuel pressure safety switch, and a external bottle vent fitting and plumbing kit.

Q. What comes with a nitrous kit?
A. Most NX systems come complete with a 10 lb nitrous bottle, stainless steel bottle brackets, 16 ft aircraft style supply line, N2O filter, lifetime warranty nitrous and fuel solenoids with mounts, all standard jet settings, an NX patented Shark nozzle (nozzles), or a patented carbureted plate, wide open throttle switch, a complete installation pack that includes all bolts, nuts, washers, wire, wire terminals, lighted arming switch, and complete instructions with pictures.

Q. How does nitrous oxide create more horsepower?
A. Nitrous oxide provides the oxygen that allows an engine to burn more fuel, more burned fuel equals more power.

Q. What is the difference between a wet and a dry system?
A. A "Wet" system introduces a homogenous mixture of nitrous and atomized fuel into the incoming air stream, thus providing a perfect air/fuel ratio for each."

 

Wet system is the best way to go but it is a lot more work. Your basicly are creating a second fuel system. I worked with NO2 before but never on a fuel injected car.
NO2 can and will damage an engine if it used wrong. The kits you can buy are just the bare min needed for the system to work. The reason I say you need to add stuff is to protect the engine. Since NO2 is just oxygen if NO2 gets to your motor with out the right amount of fuel your running lean. Lean = heat. This will fry rings, pistons and valves. This is why I say you need to upgrade injectors and pump. Is you fuel system good enough for 220 HP? yes. Is it good enough for 300HP? Maybe. Maybe is not good enough for me.

Secondly, unlike a a normal NA motor that builds power in a curve it just dumps the power in. Adding 75 HP at 1500 RPM would run cyclinder pressure thru the roof and dumping it in a 5800 RPMs could also be a bad thing. That why I said I need a window switch. Also 75 HP with the clutch pushed in or with the tranny in neutral could blow a motor in seconds.

Many guys run redundent parts just to be sure. I have heard many stories about people going to start their cars in the motor just to get a huge surpise. its a tuff way to find out something failed and filled your intake with 10 lbs of NO2 over night.

I will not be doing the upgrade anytime soon. From what I read the stock head gasket will not last long.
