Heat Wrapping Intake Tubes - Does Work!! (Supporting Data and Pictures)
Do you all share space with motorwerks, I go there a lot.
The Best of Mercedes & AMG
What about the thought that at W.O.T, the air passing through the intake tubes is moving at such a velocity, that the couple of degrees that you gain at idle, have no effect on performance when you're running flat out?
Discuss.
this can help keep temps down at the track if you are not moving with your car on i would imagine while in the staging lanes.
a data logger is really needed to confirm all of this with the hood down and under driving conditions.

The thing I wonder about, though - once everything in the engine bay gets up to temp equilibrium... will the insulating wrap slow down how quickly the tubes cool off? Logically, it would seem to... but IDK. Datalog FTW!
the exhaust wraps act as a barrier for heat to transfer from the engine bay to the intake, but does it also trap heat in the intake once there and preventing its dissipation? after all, this is the purpose of wrapping the exhaust with exhaust wrap, is it not?
also, perhaps the insulation works so well, the tubes and boxes don't get that hot and the heat to be lost is little to negligible?
this, again, would be something interesting to monitor with a data logger. i'll hopefully be getting mine soon and can do some tests why i buy material. JustPete already has his intake wrapped and will be getting data logging too, so he might do some tests and beat me to it!
Might not have much of an effect at WOT but might be decent while driving around town or when in traffic and you decide to use the beast to get away from traffic.

Anyone run Redline's Water Wetter or a coolant additive to make the intercooler more effective?
Given that the tubes are pretty short, and plastic, a minor temp change is simply not going to have much, if any effect on power production.
Cool-Tape (which would be a lot better than the velcro thing they offer, since our tubes aren't perfectly rounded)- http://www.designengineering.com/pro...p&pid=30&tid=1

I was at the Grand-Am races recently and was amazed at some of the components that the teams were wrapping in the the gold tape to keep heat out. I personally have portions of my cold air intake in my 996 wrapped in this stuff as it tends to heat soak durring long sessions at the track.

picture from the races afew weeks back as exmaple. Many of the teams had the entire intake tract including manifold wrapped.

...say they can handle up to 1500-2000F? The first link is "1 mil aluminized material bonded to a light weight, woven fiberglass" and the second link is "aluminized Heat Barriers are made up of woven silica with a flexible aluminized finish".
And what makes all of these better to use to wrap than exhaust wrap? Is it that while they reflect heat and prevent the heat from being taken up by the intake, they do not prevent the intake from dissipating the heat like the exhaust wrap might do?

good questions...the gold stuff says 850 deg and the aluminized woven says 1500 deg and the other link posted 2000 deg!!! I've seen the gold stuff from Grand Am cars quite often, both DP and GT cars use it...
I'm subscribed to this thread I think there is a best solution out there; we just need to find out what it is!

What you're looking for is how effective the material is at REFLECTING heat away from the item you're trying to protect against heat soak. I find it funny they don't publish a number stating exactly how much heat any of the chrome or wraps will keep out...just that they won't fall apart at XXX temp. They Do however publish the gold will reflect 80% of all radiant heat.
Header wrap is actually meant to keep heat IN the header and move the heat release further downstream in the exhaust system. While it does insulate some...it's still going to heat soak itself eventually as it doesn't have the reflective properties like the chrome or gold. That's why the intake sleeves are made of the chrome. It's the best balance of reflective properties without a huge price. The gold isn't cheap but it does the best job of reflecting heat away from the surface that it's on of any of them.

I'd bet my life the difference for a long duration is less than 2 degrees while looking 10x better.
Now ... having said that ... you wanna do some racing ... wet the wraps. You lose bigtime.
