The cooler the air is going in the SC, the cooler it will be when it comes out.

PV = nRT

The cold air that goes in to the SC never makes it to the cylinders as cold air. By the time that the SC heats up the air it negates the fact that you have cool air. That is why all of the intercoolers are made to work AFTER the SC/turbo. If you really want cold air going into your engine, I think zzp or intense has an intercooler for the 3800.
I would work on a SC cooling system before I would worry about ram air going into one of those SCs. It a waste of money and time if you think about it.
PV=nRT is not the correct equation for this topic. PV=nRt is for finding the characteristics of a gas. Try using Charles Law v1/t1=v2/t2, or the combined gas law, p1v1/t1=p2v2/t2. Dont go throwing around equations if you dont know what they do.

Easy macho....I am a senior in engineering at the University of Illinois. I know perfectly well what that equation does, I have seen and manipulated it myself a thousand ways. The two laws you mentioned are adaptations of mine, you just cancelled out the n'* and R'*. One can use PV=nRT to come up with P1V1=P2V2 if you like. It is all based on the Ideal Gas Law. Use the boost pressure, you can find the initial volume from several adaptations of the IGL, and one can find the temp, given one litre of gas is one mole (n) at atmospheric pressure. But I was leaving that up the readers to figure out. Next time, I will be more specific.

I agree, the most effecient way to cool the air is after it has been compressed. But the fact remains, the cooler the air is as it goes in, the cooler it is when it comes out, even though the blower has heated it up significantly.

Macho...

anyway... I was wrong about the ram intake not helping a NA car. I would add considerable hp at higher speeds. I am guessing at highway speeds you could add upwards to 30hp.

Sorry jwikoff99, I got a little carried away...

Kuhl, you should try taking some dryer ducting from a home improvement store and running it down under and behind the radiator. With your intake shield, it would be pretty easy to attach. Some people on this board have already done it into an insulated box around the filter, but I bet you could do it even easier with the shield that you have on yours.

Yep I could, but dont think I will. If i decided to I would use a 4 inch tubing and locate it on the drivers side (Ive thought bout it). I think this would improve fuel economy but I am not totally sure. It would also increase higher speed HP a considerable amount.

While I am sure the engine can take it, the tranny worries me, although it is in beautiful condition I am not sure about its limitations (it wouldnt have to be shifting a lot with that amount of air coming in). From what everyone is always saying the non HD version is pretty puny once you increase HP and torque on a normally NA system.

Okay everyone needs to stop nitpicking everything everyone else says. Its pointless and you are simply trying to make yourselves sound better which doesnt help anyone.
