-IrocZ-, dont forget in a sts turbocharged car, the air passing in that turbo has less volume and less pressure. gases tend to have more volume as the temperature increases. have u ever study thermodynamics? if you know what i am talking about, u should be able to understand my point.

I understand perfectly what you're saying even though that theory is backwards, air molecules being compressed creates friction, which creates heat, heat does not compress air, the heat is the result of compression. That's good for high PSI drag cars that only have to last a quarter mile, but for very fast and reliable street cars, it'll ruin pistons every couple of months. To make serious power with daily drivers the key is to go with higher CFM's, not just up the pressure.

heat doesnt compress air? hum!!! in a close system it does! so tell me how steam engines work?? u are heating particles which will take more space bc they vibrate more.

Shadow Z

Seems like you're the one who needs to study up on thermodynamics my friend. Heat alone cannot compress air, in a closed system heat will actually cause most gasses to expand, so you've got it backwards. Compression as I mentioned, usually in the form of mechanical force is what will compress air, a turbo pressurizing air is a decent example.

MFaust89

the gas will expand, but bc it has no room to go, it will create pressure. i think we are looking at different points.. im talking about all the air as CO2 and NO2 from the combustion. i think u are talking about the compressed air that comes from the turbo to the TB.

Shadow Z

Exactly what you just said contradicts your heat compressing air theory, the gasses would be expanding from the heat, but it has nowhere to go, limited space is what's causing the compression.

MFaust89

my view is:
more heat, gas expands, (close system), pressure increases, more potencial energy.

and about the hp number, i belive before a turbo, u should at least do some work on the heads for better flowing and a good HOME MADE (in my case) manifold intake. obvious injectors should be changed, but we cannot compare turbos unless it has been tested on the same engine specs.

PV = nRT

On the compressor side:
The comp. wheel sucks in air and spits it out in a smaller volume. That is, it compresses the air. So, since P went up and V didn't go down the same amount then T must go up. The act of compressing the air causes more heat. Air molecules are smashed into one another causes heat.

Heat goes up and cause HP to go down. Inter/Aftercooling reduces air temp. to increase HP. Latent heat removed via liquids does the same thing.

The comp. side always seems like the boring side to me. Much more going on with the turbine side in terms of HP, spool time, heat loss, back pressure, etc.

I've ran both nitrous and supercharger. If money isn't a problem, go with the Procharger. If money's tight, go with spray.

Personally, I wouldn't trade my Procharger D1 for anything, except maybe an F1.

procharger will be the best cure for the sorry top end prob with the tpi. nitrous aint going to let you push it a little harder. super charger will help get rid of that tunnel ram effect caused by the tpi do to the forced induction.

Naturally aspirated... push the limits.. be different.. any one can make big power with nitrous, turbo or supercharging..








or if you must, supercharge.. you will start to think filling bottles is a hassle.. boost is always there.. who cares about parasitic loss.. you make it back and then some..

i'm not liking this Iroc-Z guy...i'm looking into getting a supercharger (procharger) and it seems this guy is spreading alot of misinformation which he claims to be true no matter what. Maybe he's doing it to get a kick out of people but I don't like it.

Shadow Z

If you mean me, and you don't like what I say, don't read it. I couldn't care less if anyone from a forum likes me, even though I love this forum, and there's a LOT of people probably ten times smarter than me. The fact of the matter is, when EGT's aren't a problem, or you're not restricted by a certain class to use a supercharger, turbochargers are the way to go, nitrous is the most efficient of them all, but sometimes refilling bottles is a pain. The point of power adding is to get as much oxygen in the cylinder as possible right? Right. Nitrous does just that.

some people like superchargers some like turbos some like NO2 to each is own but don't sit here and say that turbos are the greatest thing on earth i don't see turbo's running on top fuel cars or any NHRA class i run a supercharger my bud son runs a garrett 42R on a honda makes 1100 horse on a drag car but like i said each is own

I understand that perfectly, but please tell me you read my whole post. I said "The fact of the matter is, when EGT's aren't a problem, or you're not restricted by a certain class to use a supercharger, turbochargers are the way to go". I honestly don't think top fuel nitromethane cars are allowed to use turbochargers, nor can they physically do it. I don't think there's a single turbo out there that can stand those kind of EGT's. Plus, a top fuel dragster needs the supercharger to make it more than an 1/8th mile. Their spark plugs are actually destroyed by then, they only run that last 1/8th from compression. That supercharger in a sense helps keep it going.
