Lightbulb Cai?!? Yea Right!!!!

Ever wonder why the factory uses plastic/rubber for the air intake tube?

Could it be that heat soaks in faster to metal then it does to plastic or rubber??

With that said im sitting at a light yesterday and im sitting there watching the Dashhawk IAT sensor creep up 130, 135, 145!!!!!!!!

You know happened when I hit the throttle when the light changed green? (WOT) It felt like there were 5 people in the car with me, I was disgusted.

The CAI tube is metal or aluminum (very thin) and it has the worst case of heatsoak I have ever seen, its hindering my PERFORMANCE!!!!!!!!
But on the highway when the CAI tube has air passing thru it constantly from a 30 mph roll the damn thing is an ANIMAL NOW!!!!!!!

So now im thinking this is where I take it in the ass at the track, waiting to stage.

Here is my idea, and everyone feel free to chime in if you think its a bad one.

I want to get the high temp silicone, the orange stuff and line the entire inside of the CAI tube with it, put a nice 1/8 to 1/4 inch bead on it to preven the heat soak from kicking the sh*t out om my IAT sensor.

Thoughts Gentlemen?

Re: Cai?!? Yea Right!!!!

Go to your local refrigeration supply wholesaler and pick up a tube of 1/2" wall armaflex insulation. Measure the outside diameter of your tube first so that you get a snug fit. Then just slide it on. I may not be pretty, but it's a cheep effective way to test your theory. And if it works, you could just install it at the track and remove it on your daily drives.

Re: Cai?!? Yea Right!!!!

As soon as my S/C arrives i will have a volant that I will not need. It is all ABS plastic. You can try to wrap your CAI in header heat wrap or get it ceramic coated.

Your best bet is a plastic intake tube like the Volant

make sure you start Icing your intake down at the track!!!

Another great idea, let me know about the Volant, I may take it off your hands for track use.

Re: Cai?!? Yea Right!!!!

Here's an even better idea. Have a small evaporator custom made to fit around the outside of you intake tube and tie it into your AC. Run your AC when you are at the track. The humidity should condense and freeze on your intake tube. When you get ready to race, turn off the AC so you don't loose any HP in the process and you will have a carry over effect with a cold intake.

Now that may be a tad overkill!
