wait isnt the intake on the left and it goes right into the exhaust?

wtf you know i know which is which, dont be an ass. its just the look i prefer instead of a bunch of tubes running all over the place. u like tubes, get tubes.

 

Actually, that's a great thought. This way you're less likely to put the air filter on the wrong pipe.

 

I really hope your kidding....

 

That cold air will start expanding as its heated before it reaches the charger. When it goes through the charger, it might as well have been from an SRI because the engine and you are not going to know the difference between the air coming from a CAI or an SRI. Most likely you'll get the same power output.

In an N/A motor the cold air will be quickly inject straight into the motor where it will expand. In a Turbo motor, that air has to first past through the gates of hell, known as turbo, before reaching the engine.

 

At the risk of starting a pissing match here I have a question. What you're saying is the temp of the air ENTERING the turbo has little or no effect on the OUTPUT of the turbo? Seems more logical to me that if the underhood temp is close to, or more than, 150 degrees and the temp near the front wheel is 90 degrees (I live in FL) the air LEAVING the turbo will be substantially cooler if drawn from outside the underhood area. I don't have any real DATA on underhood temps but I do know it gets hot under there. The cooling effect on the pipes leading to the turbo from the wheel well would help to keep the heat transfer down while passing through the engine compartment. JMHO

 

I think what he is saying is the air incoming to the turbo and out of the turbo has little effect on what the engine air temp is because it still goes through the intercooler before the engine. I guess some IAT2 recordings would be required to really compare this, but I'm of the same opinion, that SRI is good enough for a intercooled turbo car...The turbo is going generate the most heat, and it doesnt matter if it is cold air or hot air it receives, its going to heat it up...The IC is then going to cool it down as as best as it can (trying to take it back to the outside temps)

 

As long as you have a more efficient than stock IC your IAT2 should be within a couple degrees with an SRI or a CAI. That is the air temp the engine sees. Your IAT1s will be higher with a SRI but that does not matter at all as long as your IAT2s are close to ambient you are fine.

 

What about heat wrapping your cold side?? If you get the thermo wrap that you use on your DP/ Exhaust to keep the internal air hot, shouldnt it have the same effect on keeping the hot air where it belongs... OUTSIDE the CA side of your IC piping?? It should, to an extent, reduce expansion, improve flow, and keep your IAT2s at or below ambient...

All this without the addition of a SRI or CAI...which honestly seems trivial when you have a turbo tucked away in the back of an engine....IMO?

But the cold side is down low and in front of the engine where the air should be cooler to begin with. I still believe the turbo is going to develop X amount of heat. That temp should be reduced by some measure of the differential between underhood temps and outside temps. There are good arguments both ways I think. Testing with a couple of air temp guages would definitely answer the question.

 

thats a good point however, removing heat from the turbine intake is trivial. There is not a whole lot you can do to make the air entering the turbo that much cooler unfortunately. A CAI on a front mount turbo produces a better chance of bringing cooler air into the turbo without heat soak, BUT in our case, and IMO the better of the two (and like how you mentioned) the cold side of the IC goes directly into the low port intake. Which is what you really need to worry about.... IF you want to run the turbo itself at a lower temp, then you need to lower the boost or throw a larger turbo on...

 

Dan,

Any update on the SRI yet?

 

Hey all! Just so you know, I will be out of town starting tomorrow thru Monday. I'll be back in at 9 a.m. PST on Tuesday.

Have a great Memorial weekend, don't get too crazy!

 

i have an SRI, but im sure if you have a CAI it is a little more benificial in maybe cooling down your turbo lol. which in turb would slightly make the air through your chargepiping cooler which in turn leads to cooler air in your engine. not by much, and not at all above liek 30 mph, but at idle. yes.

 

How many times do we have to beat this topic dead?

 

im just saying i came in the thread and saw people still bitching. figured id throw in my final jab

 

Congrats you just won a "Fortunato Prize".

 

Intake sale is being posted now in the vendors section.

 

woot
