how long do you want the motor to last? i would go with 50 at the most if you want the motor to last any lenth of time.

Yea, 50 tops is all I would go.

What are you trying to do with the car? That would be neat to see a newer impala going down the dragstrip.

I remember seeing a newer suburban at the dragstrip that had nitrous on it. Actually ran pretty good to be how big it was.

Before You get involved with nitrous oxide, You need to understand what it does and how it works. NITROUS OXIDE is an oxygen carrier. It supplies the engine with extra oxygen to create more power. Understand that an engine runs on a proper blend of fuel and air. If You supply it with more air without mixing the additional proper amount of fuel, You have an extreme lean condition and piston melt occurs because the cylinder temperatures exceed the melting point of the aluminum piston. It can also do the same to an aluminum cylinder head and/or block. Now it will create tremendous power gains ( usually the horsepower rating of the nitrous kit is pretty accurate for Dyno tests I've done ) and at the same time stress the engine parts to the horsepower levels it's being subjected to. In other words, if an engine is designed to handle the stress levels of 300 horsepower and You subject it to a 200 HP increase with Nitrous, It being stressed by 500 horsepower. That is why special nitrous pistons, head gaskets etc. have been designed by the aftermarket to handle these excessive increase in stress levels. Now, if You have decided to use nitrous, do it right. Keep a small system in place with all the pieces recommended for the kit chosen. You hear the term " wet or dry " when referring to a kit. That simply means that either the kit will supply the extra fuel " wet " or the engine's computer will sense the increased oxygen level and the cars fuel system will supply the extra needed fuel via the computer richening the fuel mixture " dry " Most modern cars with electronic fuel injection can use a dry kit up to about 75 horsepower increase. Above that, extra fuel should be supplied via an extra fuel system complete with fuel pump, fuel lines from the tank to the intake manifold and it's own solenoid to supply the fuel when needed. Many people call nitrous users " cheaters " but there is no cheating in heads up street style racing. Keep your racing at the track and not on the streets. Don't endanger You life or anyone elses. thanks for listening.

UNCLE BILL!!! You're on this site too! I would personally go with a 75 wet shot.

That's when N2O and fuel are injected through the nozel to help keep the air fuel ratio constant.

If I wanted to run a 25 dry shot on my Colorado would I install the jet before or after the MAF? If I ran it before the MAF, wouldn't the computer since the extra oxygen and richen the mix?

I agree with a 50 hp kit its safe. Anything more is kinda of a waste (IMO) cause I am assuming the car still sees DD duty so, no since in hurtin' the engine. Just my .02 cents.

Dont forget tuning the pcm, it is so critical! rule of thumb is for every 25hp gain one should retard the timing by 1 degree.
