Cold air intake vs. cone filter on MAF...

[turbo nasty]

Good point...Cant lie Ive taken my CAI off at the track and ran with te MAF open before ..No difference...LOL

 

[scot w.]

Interesting!

So what everyone is saying is all "The Cold Air Intakes" are a Hoax?

They do not do Anything for performance?

 

[garyk1970]

I'm not sure what if anything (what the computer does to compensate for incoming air temps)is based off the intake temp sensor(i use my sm2 to monitor)......my car averaged from 125* driving around,now with my k&n moved to behind my headlight now averages 90*.......

 

[notacarlo]

colder air and plus velocity would assist as well.

Velocity from what? Ram air is useless on these cars. I got a $1200 air rammer under the hood that doesn't care how the air gets to it.

CAI is for that only. Supplying cooler air than what's under the hood.If it's advertised as "ram air" it's for some foreign jobby.

Gary good point on teh ecm recognizing the IAT...

There is a point to where underhood air temps get stupid hot with the filter under hood after sitting/idling/creeping in traffic and then once the car is at X speed where the engine bay gets evacuated of the hot air from the wind due to the speed of the vehicle.

Vs.

CAI where the air is at ambient or close from the get go

I still say the CAI will have the edge over all around Temps being closer to ambient.
But its splitting hairs as its probably only 10 degrees once oother is at speed.

At what speed the under hood filter gets closest to amb? Good question

I never liked the HOT flashing on the SM with the under hood air filter inthe summer in traffic.

But the filter does stay cleaner under the hood ill give it that

Age old debate that will never be settled! You know how I voted
though. :smile:

This is sort of like the other thread running right now about front mounts vs SLIC's. Personal preference on both subjects. One other thing not mentioned about running the filter under the hood is how it gets all buggered up by the AC hoses. Just about every TR I have seen around with a K&N under the hood has the filter all gouged up by the covering on the hoses.

 

[Pronto]

I never liked the filter all dinged up either.

 

[notacarlo]

I agree, so I removed my AC to combat the issue.:biggrin:

On the street, on a hot day when you are running the A/C, a car will most definately be faster than an identical car with a K&N on the MAF. Not by too much, but by some.

At the track, with proper cool down, its very hard to notice a difference.

+1 This makes the car not only lighter, easier to work on, and doesnt ding up the air filter

So what your saying is that guys like Don Cruz, Adam C, Jason Cramer and others that race TSM that are running Cold Air Intakes "THEY ARE NOT ADDING ANYTHING PEFORMANCE WISE?"

They get proper cool down too!


Just wanting to know why a TON of people have them and why the TSM racers are using them if there is no difference!

In the game of feet its all about inches. The inches they crave have nothing to do with real street car results. On a street car the filter will be like a giant hoover sucking all the dirt of the road.. clogging the filter sooner than latter. Something that is not an issue with a race car that is seldom if never street driven.

The first time you lose performance and pull your hair out for weeks trying to figure where your lost MPH went.. and you come to find out it was a clogged K&N.. you'll rethink your stance.

Been there.. got the T-shirt and had the clogged K&N cost me 4 MPH trap speed decrease

I have a K+N filter cleaner kit, I clean it 3 times a year at most.

Driven daily including salty sandy roads and in the winter.

And my scammaster ain't stuck on HOT anymore all summer.

On the street it's a no brainer.

Most people here only drive their cars on the internet even with no A/C.

I replace the K+N at 5 year intervals instead of 10 now so you really have to think hard whether or not cold air kits are a good idea cost wise. :biggrin:

Oh and you can ding them up under the bumper too if facts are really important in this discussion.

Under the hood the radiator fan causes a giant vortex just like a tornado messing up the air flow, hey it's as good as that Hoover theory. :biggrin:

A Front Mount will make the MAF mounted K&N much hotter than a stock location intercooler will, maybe enough to make a measurable difference.

.05 seconds on a 9 second car is huge, especially if it runs 9.04. On a 12.8 second car, not so much.

 

[Mr.Spool]

okay i will jump in i ran a cold air kit for years as well as the cone off the maf,i see no performance difference at the track on a low 11 second car.the filter does get dirty faster with it outside the car vs in.people always believe they are getting cool air outside the car like an artic blast,newsflash that road is getting nice and toasty out in the sun and that heat rises well above the cold air intake and that temp is far from ambient mine currently is inside the car.

No special stance here, Just simply trying to figure out why!

Well i'm running a front mount on this car for the first time and I can tell you one thing your right on the under the hood temps being higher with a FMIC!

Now i'm in quite a bit of stop and go traffic and I made my own CAI and the IAT has been ALOT lower due to it being relocated.

Just wanted to know if this CAI stuff was considered a hoax or not..

If the scanmaster says "HOT" while cruising.. no big deal. Most engines run at least 130-150 degree's for IAT while cruising and driving around. If you dont like it to say "HOT" then put on a CAI or move the IAT sensor to behind the bumper. A lot of weight is being given to a sensor which does nothing to the ecm as far as performance, measuring air temperature which has nothing to do with true temperature going into the engine.

Meaning if the IAT(MAT) sensor is mounted inside the plenum, you would then see true temperature inside the engine. After all, it is where we want to really see whats going on. At that point, turbo, IC, plumbing, etc all get packaged neatly into figuring whats truly going on. Simply reading a thermistor mounted behind the core support...

On aftermarket ECU's the IAT can be used to affect timing and functions. Some use it for alky failsafe's.

So will a CAI make a difference?? install it at the track after you've done two baseline runs without it. You will then have your particular results. I wont even get into whose CAI system.. as there are quite a few.

FWIW I dont run one. Thats just my prefernence.

 

[challengermike]

Doesnt everybodys car pickup when its cooler out?Thats got to be the colder air,so i would think pulling cooler air has to help some.Im pretty sure that you would run faster if it was 60 out and not 100.I know the temp difference on mine was drastic,130 to what ever the outside temp is.Only rises a few degrees when sitting in traffic.For an allout race car things might be different due to inner fenders maybe missing and what ever else has been taken off to lighten the car,i would think it would have alot of air flowing around in there.
