Go feed 30F air into your turbo and measure the output temperature. Do it again with 130F air.

Let me know how that goes

 

this is florida, where is the air 30 degrees?

CAI can be FAIL because you can hydrolock

intake is only as cool as the intercooler is cooling anyway.

 

I got the impression you were smarter than this from previous posts.

So, because FL doesn't get 30F temps, none of the rules apply?

It doesn't matter what the lowest temperature in FL is. It was an example with a dramatic ambient temperature difference to make a point. If you'd like a more "Florida Realistic" example, go feed 80F into your turbo and measure the output temperature, then do the same at 130F.

Intake air temperature is always relevant. Turbo/super-charging does not negate this. Every degree of temperature from outside your air filter to your combustion chamber counts.

Sure, CAI's fed from near the ground are prone to sucking in water. Where is the rule of law that says a "cold air intake" has to live near the ground? Feed the air from the front of the car to a thermally insulated filter box in the engine bay.

 

dude honestly, i think you and i both know there is no difference between a CAI and a short ram! the heat is still there. Its still gonna be hot as balls if the intake is like 2 inches longer going into the fender!

 

so then enjoy your extra 2 hp

seriously with the way it rains here in the summer i'd be scared of sucking in too much water

my vette has a vararam on it...and its lowered. i do not want to drive it in the water because a big enough puddle and there is a real engine bill for you.

yes cai gets lower temps of course. but seriously how many hp will either intake add to a suby like 3? oh i has dyno graphs of 10-15whp or whatever. most aren't needed unless you are installing an fmic or get above the 300whp level where the stock airbox starts to become restrictive. so yes, im an idiot i just said find me 30 degree air in florida. its impossible. maybe 2 days a year...30 degree air + rain= snow how often do you see that in fl!?

 

You're looking at roughly 1% HP increase with every 10 degrees of temperature you shave.

At 300HP, that's 3HP added for every 10 degrees F.

At 90F ambient temps and 130F in the engine bay where the typical SRI is installed, that's 12 free HP.

Combine it with other similar mods to keep the intake path as cool as possible and you're looking at close to 20HP.

I did not once recommend a CAI jammed near the ground, and I am not saying that now. Did you even read my comment on that topic above?

Your choice of lost HP aside, the topic is whether or not there is a difference, and there sure as hell is. You guys can talk in sidetracking circles all you want about the topic.

Later.

 

Im not trying to side track! how are you figureing numbers for 1% HP increase for every 10 degrees. just curious, no sarcasm!

Im a firm believer that reagardless if you have a SRI or a CAI, the temps are going to be the same! and by the time the air travels thru the filter into the intake tube, then thru the inlet hose! its still gonna be HOT!

 

get a blow thru and short ram/cai doesnt matter because the air temps change from using a fmic like josh stated my intake temps are 1-3~ off of w.e the outside temps are once the car starts moving... yea having the maf on the intake can effect the cars hp gains because a short rams going to read hotter temps then a cai but thats not the actual air temps that are entering the throttle body.... so technically both sides are correct but depending on the setup the car has

 

Not a chance I am continuing this conversation.

You folks believe what you want.

If you want to figure it out, study and learn instead of theorizing, accepting word of mouth, or just blindly telling yourself something in order to feel okay with what you've purchased.

The information is out there.

Be sure to let OEM ECU calibrators and tuners around the world know when you have proven that IAT fuel orrection maps and measurement of IATs at the intake... are completely unnecessary.

there is an actaul equation somewhere which i can't seem to find right now that explains it, but its a general saying.

here's a small article on how temps effect hp.
