okay, we've kinda got an online debate in the regional section....but i figured i'd open it up so everyone can give me the smack down. my question was, "is putting a cold air intake on a turbo car, any more effective than a short ram intake on a turbo car?" i don't see that the cold air part would help, seeing as how the turbo is jamming so much air in as it is. okay, it's up in the air, let me have it

 

If you're satisfied with getting "enough" air in there, then it won't matter, BUT if you are going to all the trouble of a turbocharger, why wouldn't you at least try to optimize it? Why would you spend thousands on a turbo and skimp $100 on the intake?

Turbo or not, the CAI principle is the same. Sure, the turbo's pushing lots of air, but if you can get it pushing colder, denser air, then it will be that much more effective. Theoretically of course, in reality there may not be much difference.

 

I think i just got stupider reading this post. The lack of actual tech here surprises me. With a turbo charger how do you plan on running an intake at all? Do you know the concept of a turbocharger? Obvciously not so lets explain:

1.The motor makes exhaust gas
2.The exhaust gas goes through a exhaust manifold
3. The turbo is connected to the exhaust manifold
4. the exhaust gasses "spools" the turbo compressor
5.This forces air out
6.the air travels down to the FMIC via a Charge pipe
7.the air passes through the FMIC or SMIC
8.The goes up to the intake manifold VIA a up pipe (this is why you can't have an intake with a turbo...the up pipe is there
9.When the throttle body closes the extra air is released VIA a BOV so not to go back into the turbo and caus edamage to it.

This is why you have a "turbo lag" you need time for the exhaust gases to spool the compressor wheel. so with a turbo set up you can't have a CAI or a short ram, you have a up-pipe

 

That's funny, cuz I think I feel like more of an a-hole after reading your reply.


Please explain to me where the turbo gets the air from? Ever hear of an air inlet and an Exhaust gas discharge? The exhaust spins the turbine, but the air exits from there. It will draw air in from the other side through WHAT???? an intake...

 

okay, but doesn't the air heat up going through the turbo anyways? dunno, just don't see how there can be that big of a difference. but, you're right about skimping the 100 if you've already sprung for the turbo....

 

Yes, compressing the air will cause it to heat up, even more reason why a CAI would be beneficial.

 

it's not an intake. it is Ambient Air Inlet, not an Air Intake. It will make no diffrence if you have a pipe comming off of that or not. The air comes from the exhaust gas, that is what pushes the turbine and compressor wheel. The Ambient air intake is providing the air which will be "compressed" to run through the FMIC or SMIC. Whic inturn goes into the Intake manifold. It doesn't provide any performance gains to have a "cold air intake" It just provide the air to be compressed

EDIT: If you pay 100 bucks for a filter and a pipe to come off of a turbo you are dumb. It doesn't matter if you suck in hot air or cold air into the turob, it just provides air to be compressed

 

^^^ you must have had a vw before you box....and own a mac. yeash. its funny how even though the terminology i used might be a little wrong, scionic man got it and answered my question. thanks for sorta answering my question though....

 

actually i had a 480 HP turbocharged Honda, and just recently built a 600+hp turbocharged Honda.....i know a few things about turbocharging

 

i wasn't questioning your knowledge on turbo's, i was refering to the fact that you're ****......

 

What is the point in using the wrong terms. go to a engine builder or a turbo builder and say "i need an intake for my turbo setup" They will laugh. When people think of an intake system they think AEM. Just trying to put the correct termanology and knowledge where it needs to be

 

True it turns the wheel, then the exhaust gas exits



This would be called WHAT???

Cold air compresses better...

Just because you bolted some parts together doesn't make you THE authority...

The fact that you will tell us that the air going in doesn't matter makes me question all your supposed experience.

 

well, now that i think of it, i had a friend with a turbo eclipse, and he had an intake.....a traditional intake. don't remember exactly the layout. anywho....i think if i went to a turbo expert, he'd probably explain to me why my terminology was wrong, and what the right terminology is.....

 

which is what i did. Eclipses are designed diffrently. You can't compare a stock turbo car to a aftermarket turbo car.

 

The air doesn't matter, why do you have a Intercoller, To cool the air while compressing is a bad idea. That is why you run an intercooler, to cool the air before it goes into the intake manifold

Cool air on the turbo side does nothing. Cool air on the intake side going into the intake manifold is where it matters. Because cool air inside the combustion chamber is where it is going to help. Cool air on the exhaust side doe snotrhing

 

maybe you're just coming off as a jerk, so i'm taking offense to your replys.... dunno. thanks for the info though.

 

 

back to the original question.


yes you can put a CAI and gain HP depending on the car and turbo. some turbo's dont need the short ram at all and jus prefer to go straight off a filter. (if that made any sense)

i read that if you put a CAI on the SRT4, you can gain lots of HP. but on high HP cars like a skyline pusing 800+... i dunt tink the CAI is going to make a difference.

get my drift?

 

I'd love to hear why this is bad...

 

it doesn't matter! that is why. It doesn't matter if the air your compressing is cold or not. It is going to get cold when it passes through the intercooler, that is why the intercooler is there, not using an intercooler causes heatsoak. Sucking in cold air to 1500 degree exhaust gas does nothing. How you get cold air to the intake mani is with a good intercooler, not by sucking in 70 degreee ait through a filter getting dumped into a 1500 degree exhaust gas mix
