I see in your sig you have a C&L Mass air meter. I believe they do not recommend using their meter with any cold air kit. I would just keep what you have.stanggt00 said:Anyone out there using the densecharger system? What are peoples inputs on it?
Do you work for Densecharger? Cuz thats a bunch of crap.... I've got a 4"/3.5" steel pipe that I built and right after driving you can easily hold your hand on it, only fairly warm and plastic would be about the same. The incoming air keeps the pipe cool, the only time steel might get significantly hotter is if you let it sit and heat soak with the hood closed after running, but it would cool back down shortly after startup anyway.Ryan98GT said:Just do this simple test if you are debating between the densecharger and something like the BBK or MAC kit.......Drive the car for 15 minutes with each kit on there....open the hood and grab the inlet tube with your hand.......I bet you don't hold the MAC or BBK kits very long!!! It will burn your hand off!!
Now try the densecharger.....AHHH....nice and cool.
aaaaaarrrrgggghhhhhh!!! Why can't people read anything before replying to a thread? I'll quote myself from just a few replies ago....twokingsracer said:Here is my question regarding the steel CAI's...is the air cooling off the metal or staying cool as it goes into the intake. Think abou this for just a second...heat transfer.
aaaaaarrrrgggghhhhhh!!! Why can't people read anything before replying to a thread? I'll quote myself from just a few replies ago....
I did read it. How much do I think its picking up? You tell me...your doing the mathmatical calculations. Its still picking up heat from the metal. How the hell else is it cooling it off? Magic? Nice formula though. As for your setup, it sounds very good, the length of the straight pipe in front of the meter is what makes the difference I would guess. Some of the CAI setups I have seen dont have that...its more like two to four inches. I have read and been told that the optimal distance for tubing is 7 to 8 times the diameter of the MAF on either side, but 4 to 5 times will work just fine.Just how much heat do you think that air will pick up in .015 seconds?
Riiiggghhhtt..... *IF* the inlet tube were hot, car were not running, and you physically closed off both ends of the tube that might be a somewhat valid comparison....however compared to a dynamic environment where the air is moving through at very high velocity its meaningless. Why don't you go put a big fan in that car to exchange the air a few times every second and see how hot it gets inside then....twokingsracer said:Liken in to the ambient temp of air in a closed up car on a summer day.
First of all the inlet tube is going to be HOT from the engine that is RUNNING. How ****ing hard is this to understand? The STEEL is hot because it is setting next to a HOT RUNNING MOTOR, it IS enclosed with that HOT RUNNING MOTOR. And since IT IS MADE OF STEEL, its going to retain the heat from the AMBIENT TEMP UNDER THE HOOD. The temp under the hood is EXTREMELY high, which heats the metal, which inturn heats the interior of the tube. That is what Im saying. So, the cool air comes in and cools (to a minor extent) the metal tube...how, heat transfer to the air. So, that being said, the incoming air will rise in temp to some degree. THAT IS ALL I WAS TRYING TO SAY!! I dont know how many times I have read where guys state that they cant lay their hands on the steel tubing of a CAI after running the car for some time. I have not read any posts where guys have said, "You know what? I ran my car six passes today and drove home...and soon as I got there I could put my hand on that CAI." The heat from the engine makes it hot...just like it does a lot of other metal parts. Thats all Im pointing out. I wouldnt buy a steel CAI if I had the money in my pocket...I would put one on if it were given to me. I have however done like you, and made a straight flowing air intake tube with PVC, and yes...I can lay my hand on it after running it, it will be warm from the heat produced by the engine, but that is it. I stated earlier that plastic was a more efficient material than steel did I not? I never ****ing endorsed steel CAI's.TurboX2 said:ambient = outside temp

I will admit that was a bad comparison in terms of syntax. I should have expounded on it and further stated that the ambient air in the car would raise the temperature of cooler air that comes in. Since there was a constant heat source, in this case a running engine, even though the air would cool the pipe...it is still picking up heat that is retained by the tubing, which is caused by the running engine. I am not trying to say the air is going to be that hot, just hotter than when it was in the fender well.Liken in to the ambient temp of air in a closed up car on a summer day.
