I don't like the fact that is sucking air from inside the engine compartment. I guess that is why it is a "AI" instead of of a "CAI".

Agreed. Looks nice, however.
One of these days, someone needs to place a few temperature probes around the engine bay, outside, etc., and really see what the temperature differences are.
It won't tell us about airflow, however.

Good points, but we know it gets hot under there!

Chris,
Go to www.m5board.com and do a search on air intake temp sensor, the author is greg. He has a very nicely done study of temps under the hood, in the airbox at the MAFS etc at various speeds and throttle openings.

If the valve cover are going to buble up again, I not sure it is worth the trouble. It seems to be a problem that we all have.

The version 142.52.39.105
Cold Air Intake E39 540 (http://www.racdyn-usa.com/Merchant2/merchant.mv?Screen=PROD&Product_Code=142.52.39.105) doesn't suck in air from inside the engine compartment.
The heat sheild is designed to stop from pulling in air from the inside of the engine compartment, pulling cooler air from outside of the car, however not droppping the filter behind the bumper where there is not much air flowing and the risk of pulling in water.

Ahh, checked out the link, in those pictures one can see the side shield, and I am guessing that the hood insulation closes off and insulates the area from excess heat. Any tests to see how much of horsepower difference one gets by using "just" your CAI?

That is correct. The shield mates up to the insulation of the hood to insulate the air from the heat of the rest of the engine compartment. This is a new product, the heat shielded version, and we have yet to dyno test it. So for, we have only been able to "seat dyno" it, the feel which you get from driving it. On open roads it provides more throttle response than our original version and feels as if added about 2 or 3 hp over the original. The should is not changed. Sitting in traffic, there is little difference of the two, it is mostly once that fresh air from the front in starts to rush in.

A couple of comments:
1) "over the orignal" is that OEM?
2) How can you not have dynoed? I have bought mods and go dyno as soon as possible. Your company does this for a living and you test for maximum results don't you?

I don't think you will, you "may" get more throttle response but what I think you will get is more sound, so you will "hear" the throttle response.

As in feels like. I wasn't trying to miss inform you. As I stated, it has yet to be on the dyno. You can feel hp normally. Well, an increase or a decrease, and you can estimate from the way the car feels in comparison to how it "felt" before. We are in current development of a few other shields for other models, and once completed, we should be testing them all.

There is certainly an increase of sound than the stock system, or even a system with the drop in filters. I stated earlier that the sound between our two versions, with or without heat shield there is not much sound difference, meaning within the two, not over the stock setup.

Thats cool. I was just asking because I myself find it quite hard to feel a 5hp or less increase. But i'm no expert.

Thanks for your response.
It seems to me if you test the car without the heat shield it could be worse than OEM, because OEM tries to bring in cooler air althought it through a smaller hole.
So, if you compare the non shield to the shield you would hope that there would be a difference although it may not be that much over OEM.
Is that a logical way to look at it?

Good way of thinking. However, with the version without the heatshield, we don't block of any of the OEM pathing for cooler air. Those paths are no longer directed to the box that gets removed, but are in the path way of where the intake recieve air. That air does mix with the warm air of the engine compartment, however the air flow is increased so much with the smother piper and open air filter that the warm air mixture is still an improvement from OE.
The point of having colder air is that it is more condense, meaning more air can be consentrated into the engine. By using the orginal intake, you accomplish this because of the open air filter and piping, as well as it is still pulling in that cooler air from the OE locations.
So, there is the improvement overstock.
The next step -heat shield. Lets block off that warm air mixing in, so not only is there now more air flow, it is even cooler and more condense = MORE AIR! More Power!
The orginal non heat shield version did make 5-6 hp as it was tested.
We are expecting now 7-9hp from the new version (not tested yet).

Will the intake be CARB exempt? (California Air Resource Board) - Smog legal.

Thanks for clarifying that, very good response :thumbup:
5-6 HP is more that I expected from the Original set up. I am glad you guys are willing to quantify your products.
Thanks again.

Must have a very sensative ass to feel 2-3HP. :bareass:
CAIs are the biggest scam in the aftermarket industry.

If this does provide 5+ HP and improved trottle response, the price is certainly right.

In virtually any context in which you wish to put it.
They charge enormous prices for virtually no verifiable improvement.
I am not raining on anyones parade I just think there are better ways to spend that money. Like a driving school.
