Anyone have any ways to gain easy horse power? If so please direct me to it.

nitrous. easy and cheap.

99cavguy

running cheater juice through a stock system isnt exactly what id recommend.. if i were you i'd go with a cold air intake, new exhaust, or even a supercharger... they aren't as complicated or expensive as you would think.. but yeah there are many more but im not gonna sit here all day if you want me to send you a list of the things im putting on my cav for ideas just pm me.. l8a

No such animal as an easy (or cheap) HP gain.
Cold air intakes only work if they're sucking air from OUTSIDE the engine room beside or in front of the radiator.
New exhaust doesn't do crap but waste money unless it's got the performance mods to make it matter.
Nitrous (in any real proportions on a stock motor without the extra fuel delivery capability and timing mods is also a waste and will actually rob performance. (Nitrous Oxide is a NON-flammable gas, dig? The only reason people use it to develop more power is because at 565 degrees F (like in a combustion chamber) it breaks down into what it's made of (Nitrogen and OXYGEN=the part you want) With that extra oxygen-you can dump even more fuel into the combustion chamber=developing more power in the same space) But ya better have forged pistons and a hard-ass crankshaft and valves and some heavy duty head gasketing to handle the extra presssures.)

Nitrous by itself is non flammable and will only make you laugh if you inhale it due to oxygen deprivation.

Your best bet would be to upgrade your head gasket and add the turbo setup from a similar engine-don't forget to reprogram/swap the ECM so it knows how it's supposed to work.
Turbos do exactly what nitrous does-same HP gains as nitrous.
Except turbos work on demand more or less so pressure builds as it's needed instead of before it's needed.

Actually, nitrous is not the same stuff you would get at a dentist office. Nitrous is flammable, since it is a mixture of nitrogen and oxygen. If you were to say the nitrogen in nitrous oxide is not not flammable then that would be true.

I do not know how you could recommend running FI on a stock motor and not nitrous. If you crank the boost to 20psi with an FI setup on a stock motor your going to blow the motor, just like if you spray 125shot of nitrous, you are going to blow the motor. Nitrous is the cheapest way to make a lot of power compared to other things, sure you can spray all the time, but who needs that constant power 24/7?

But you wouldn't Crank it up to 20 psi. Depending on the engine it can easily run 9-12 PSI without a problem. Maybe more if you add an intercooler and water injection (too cool the combustion temps.) Run that with regular pump gas. There shouldn't be a problem.

just like you wouldnt run a 125shot of nitrous, you would run more like 35-50shot. also i wouldnt recomend running 9-12psi alot, with out an intercooler. but at those levels of boost you would want to atleast you did some internal work

Yes, it IS the same stuff you get at the dentist..these aren't "different atoms". The stuff you get at the dentist is just sweetened so it's not objectionable to breathe. Your engine on the other hand doesn't care what it tastes like.
Like I said. Nitrous oxide is a NON-flammable gas. True, there is oxygen in there, but in combination with the inert gas nitrogen-it just ain't gonna burn like it is. Water has hydrogen and oxygen in it which by themselves are flammable as hell-but I ain't gonna try to hold my breath while you try to light some water on fire, dig?
You can separate water into it's basic elements- and those separate elements will burn very nicely, but in it's natural state, it ain't a happenin' thing.
If oxygen was that flammable in it's natural state-you couldn't have an open flame anywheres for fear of immolating yourself. Yes. It SUPPORTS combustion.

That damned FnF movie-all it did was warp people's minds.
That car blowing up 'cause it got shot just can't happen. Period.
I got a bottle of nitrous sitting outside my shop. I could fire up my torch and hold it in front of the outlet on that bottle and open the valve wide and all's it'd do is blow out the torch flame. Try it. You'll see. I could shoot that bottle but it wouldn't explode-it might take off like a rocket or just fall over because of the sudden uncontrolled pressure release thru the bullet hole, but there'd be no flames-just the action/equal and opposite reaction thing. Bullet pierces vessel/pressure escapes violently/vessel takes off in opposite direction until pressure release subsides. Pure physics.
The reason it works in an internal combustion engine is because the heat in side that engine is in excess of the 565 degrees necessary to chemically break down nitrous oxide into it's basic parts-one of which is oxygen-which by itself won't do diddly squat to increase power output any more than sticking a cold air intake and a fart can on your car will increase HP.
The whole idea is to maintain as close to that 14.7:1 stoichometric
fuel/air mixture that enables an internal combustion engine to produce it's maximum potential output.
By injecting the nitrous-you are in effect injecting even more oxygen into the same combustion space-thereby enabling you to inject a proportionate amount of more fuel into that same space as well at the same time-effectively increasing the volume of the fuel/air charge enabling the engine to output more power from the same displacement.
This can be hard on a stock engine.
What's even worse is that people who don't understand the theory behind nitrous injection just shoot the stuff in there and LEAN out the mixture severely enough to cause really bad detonations which will blow holes in pistons and effectively trash the engine in a very short time.
You get the exact same benefit from a turbo or a blower as you would get from nitrous except on the turbo/blower systems-it works on engine DEMAND (using plain, old atmospheric oxygen which is the same stuff that nitrous produces)-which while still a bit harder on the engine's structure is not nearly as harmful as increasing the fuel/air charge before it's really necessary or in the wrong proportions.

German piston-engined fighter planes were some of the first to use this nitrous injection-then they figured out how to make more reliable turbos.

The crux of the matter is: Nitrous only leans out the mixture unless you also add the extra fuel at the same time to keep that 14.7:1 air/fuel ratio-just in greater volume.
A bomb is just a really hot fire burning very quickly in a confined space.
Your engine just does this many thousand times per minute.
If you put more bomb in the same space-the result is a bigger explosion and more power output.
Fire needs three things to burn efficiently:
Heat, air, and fuel.
If even one of those is absent or in the wrong proportions-one of two things happens.
Either there will be no fire or combustion will not be complete resulting in an inefficient burn and power loss.

Nitrous oxide is not magic. There is a chemical reaction process going on there. Nothing more-nothing less.

actually n2o is flamable. and it is not exactly the same thing that a dentist has. In a basic sense it is but not nearly as pure.

Uh, huh. You guys seen that damned movie too many times.
