Question: to all your tech guys/gals...from the looks of it...the blitz and the powerenterprise S/C both have a short ram intake...and i guess that how all S/C and tubros have...right? well my question is...i have the SPFR CAI...is there any way to combine the two...i mean have the CAI intake work w/ the S/C...anyone?

 

With a supercharger I'm not sure if the intakes goes where the throttle body still is. It make be blocked or moved. As far as turbo's go. Intakes would be attached on the compressor side of the turbo, so where ever the turbo goes, is where the intake goes. In a turbo's case, you wouldn't be able to use any intake designed for a NA car.

 

you can't use a CAI or short ram intake in conjunction with a turbo or s/c

turbo and s/c's are forced induction - meaning they use a turbine to force air into the intake at a higher pressure. so a passive system like a cai would have to be removed.

Not True. I have seen CAI on turbo that route piping to under fenderwells and what not. There's just more piping.

 

NOT TRUE! The san diego dealer car has the blitz S/C with the AEM CAI! check yo facts

 

ok, guess i was wrong - but i don't think it's going to add anything powerwise, especially on a turbo car, which uses hot exhaust gasses to pressurize the air going into the intake...

 

the hot exauhst gasses don't mix with the intake gases.

most of the heat added to the air in a turbocharged car is from compression heat, and superchargers will do the same thing.

Some argue that the air will get heated by the compression regardless, so that it doesn't matter if you suck in cold air or hot. I don't know if this is true or not.

you can use whatever kind of intake you want, turbo or SC, it just depends if the kit has the clearance for it, and you may have to custom make some attachments etc.

 

Actually, turbo cars benefit from CAI a lot. I suppose i'm going to start war with this,
but.. even with the SUPER LONG piping, the colder air HELPS. And it does make more power than conventional intakes. Just think of how hot the engine bay gets with FI. Then think of how much colder the fenderwells are.

 

yea but if you have an IC it really doesnt matter too much but i have seen small gains with a cold air intake on my wrx.

 

I remembered that Drew saw the Blitz intake on another (?) SC set-up?

 

I'm not completely sure but that pic shows looks like the CAI is still hooked up to the Throttle body. OR what was the TB, Which is ....


OH nevermind this comment , I looked and I am really impressed.

If only I could get one.

PS Does the s/c use a new intake manifold?

 

do you have anything to substantiate this assertion?

the 700-900hp supras usually just have a filter sitting there in the engine bay.

 

I've seen dyno graphs from a 2g DSM w/ 50 trim turbo that made more power with a cold air intake that was routed into the fenderwell, compared to a intake where the filter was several inches from the blazing hot compressor housing.

There's a formula that shows how it works, i just can't put my finger on it. it's something like for every X amount of degrees colder (denser) air equals roughly
X of power increase.

Someone help a brotha out.

 

First, let me say that this is a great forum. I'm going to be buying an xA in about 2 mos. and I can't believe the amount of information already available.

Ok, now the reason for the reply (this might get long-I'm sorry if it does). A cold air intake, one that will pull ambient temperature air, is near a must for any charged application.

Temperature is the average kenetic (motion) energy of the molecules of a substance. This is HEAT. The best way to think about this is that heat is energy, or the actual energy possesed by any molecule of air....it's motion. As you compress any vapor, the molecules get closer together, but still have same amount of energy(motion) they had before they were crammed into your intake like sardines. This means that the air will have more heat or energy per cubic foot-inch-centimeter of space than it did before, because there is more of it.

That being said, lets say the ambient temp was 50 deg, and your under hood temp was 100 deg(purely hypothetical most are probably higher, but I've never tested). If you decided to pull the air from the engine bay the intake air would have many times the energy per volume then if you had pulled from outside the car. You would think twice as much energy when compressed, but that's not correct because it's directly related to the volume. I would like to give you all exact numbers, but I don't have the formulas in front of me.

Having a colder intake charge won't necessarily make more power, but it will give you more reliability and longevity. Also if you want to make big power with any charged engine you'll need to be pulling in cold air, because the colder the intake charge the less the chance of detonation, or the higher the compression before detonation.

That's my buck fifty(I never give just 2 cents). Run with it

with forced induction set up, cooler intake temps mean the world. It dosent matter if the air gets heated during compression in the wheel and it dosent matter if you have an intercooler. But running hoter air through the intercooler you lower its efficiency.
Remember, its all about air mass. The cooler the air, the more dense. The more dense the more you can fit in a given space.

If the air being drawn into the turbo/SC is cooler, it will in turn be MORE air. Air quanity is what makes power. And air quanity if directly related to air temp.
