Ok everyone I was thinking about it....we all try and try to get colder air into our engines but what about just rerouting the heater line going into the throttle body??? Has anyone ever thought of this....or tried it??? Just a thought though...I'm thinking about doing it if I still go turbo...that line is going to be my turbo coolant line anyways.

Thanks Jesse I had a feeling you would chime in on that...I believe I'm going to do that since I'm going to use that line for the turbo coolant I would rather not run it through a boiling turbo center section to warm up my throttle body so I will bypass and let the coolant go back into the works instead of the throttle.

you know on a side note, I was wondering about using compressed air like N2O. I mean if you were to fill up your N2O tank with just compressed air and ran it like N2O would it hurt anything? I would think that the compressed air would be like Forced induction and add quite a jolt, but would using your N2O kit affect anything like air/fuel mixture? This is just something I might play with. What do you guys think?

That's an interesting idea actually. I think N2O has a cooling effect that standard compressed air, or CO2 lacks. Also, the different gasses probably have different properties when it comes to flamablilty. Where's Chemchild? My knowledge of gas properties is very faint...

now someone correct me, but NO2 simply has a higher combustibility rate and provides more pack for punch then standard air, which is why it imporves HP, now are theier other gases that also do this

Nitrous oxide is made up of 2 parts nitrogen and one part oxygen (36% oxygen by weight). During the combustion process in an engine, at about 572 degrees F, nitrous breaks down and releases oxygen. This extra oxygen creates additional power by allowing more fuel to be burned. Nitrogen acts to buffer, or dampen the increased cylinder pressures helping to control the combustion process. Nitrous also has a tremendous "intercooling" effect by reducing intake charge temperatures by 60 to 75 degrees F.

Not CO2, CO2 is carbon dioxide, that is not the same as Compreesed air that you would get out of an air compressor. If I wanted CO2 I would get it from work because that is what we use in our Coca-cola Fountains. Now would just compressed air work?
I'm talking about putting compressed air in the nitrous tank(that I already have) and using it as a forced induction system. Is this what you are thinking? Because it would cost nothing to refill your tank if you have an air compressor and there would be no venting N2O into the atmosphere.
I mean this would be like having a ram air hood affect I would think, and the only thing I'm wondering is if the ZEX Kit I have would read the Compressed air as N2O and add extra fuel. If it did add extra fuel would it hurt anything and could I just change the jets to restrict the fuel flow? Hmm....this sounds like it would work to me but I

So whats the point of a "Ram Air" Hood? I mean why get a "Ram Air" hood if the extra air "Forced" into the intake does nothing for HP? And compressed air is not CO2.

Filling your existing ZEX system with compressed air, and triggering the system, would cause the ZEX control module to increase the fuel pressure in the fuel rail. That means more fuel. Changing nozzles only effects the amount of gas in the bottle being released. The extra fuel is delivered via the stock injectors by the ZEX control model adjusting the vacuum to the stock fuel pressure regulator. There are two differences I can think of between forced induction or ram air and a N2O system. The first is the added pressure is being generated at the beginning of the intake system, not in the middle. If you released enough air through the N2O system to actually create positive pressure in the intake system, what is there to stop it from reversing direction and flowing out the intake system? Second, the N2O system releases the gas after the mass air flow sensor, so the PCM isn't compensating for it, only the N2O kit's control module is. As I said, it was an interesting idea, but I think Don668 answered this with the quote from Holley's website. Nitrous has properties that are conducive to use in an engine.

Eric is right about the pressure bleeding out the intake system in the reverse (past the throttle plate). The Nitrous systems use the Nitrogen/Oxygen combo to deliver the charge to the intake system where it then is burned. The Nitrous follows the air entering the motor (Vacuum - pushed in by the air outside) but if you had pressure in the intake system higher than the surrounding environment, the air would choose the easiest route and your gains would be minimal if any. You have to remeber that an increase in intake manifold pressure is created by a turbo or supercharger and it's packing more air behind that. N2O systems don't increase the intake manifolds pressure it's still the same as a stock car. To crate a substantial gain in power you would also need a lot of extra compressed air I don't think an old NOS bottle would hold enough for much more than 1 good blast!
You would see better gains from a water injection system...and all that does is allows you to run more advance in the timing department.
