heat wrapping intakes?

edub370 · 10-02-2012, 11:20 AM

so i know we can all tell after we've been driving the z for a while. it gets hot under the hood, our cars pull timing, and sh!t gets sluggish. so why has nobody tried throwing some header wrap on their long tubes to prevent that metal from getting hot? idk if anyone has ever tried grabbing their long tube intakes after driving a while, but they are hot as hell. at least my injen is.

so what would prevent someone from throwing some header wrap on the intake piping to keep the hot air out and cold air in. or is header wrap unidirectional? i.e. header wrap is designed to keep the headers heat in, whereas we want to keep heat out? would it be worth looking in to....?

another random idea...

I actually have seen this done on other cars. I’m pretty sure somebody has done this to their Z.

My understanding is the main reason is to prevent corrosion, water can stay underneath the wrap which will start the pipe to corrode.....

im not sure at all tho..... i have this debate with myself regularly on my Z and my 11" sti stage 2 with dump tub plumbed back it...

in the end im mostly likely going to take my pipes Z, swaintech coated and wrapped when boosted and get the sti just coated. Most likely it's just a Band-Aid, not really fixing the real problem of the heat in our engine bays.

Its the wrong type of heat control for the application. The header wrap is meant to retain heat in the manifolds. You do not want to keep heat in your intake system. Most companies have come to the market with reflective tape that helps prevent the piping from getting heat soaked from the engine bay temperatures. You can see some reflective heat tape HERE. This would be the right stuff to wrap an intake with!

Heat wrap (or insulating wrap) is what you use on the exhaust to keep heat IN. You would want exactly the opposite on the intake side, which is to keep heat OUT.

For that you would use heat shielding, typically gold foil. See the picture below.

thanks for the responses. thats what i was kinda wondering. man if only that reflective stuff wasnt so ugly lol.

any intake temp charts available that shows the delta between using this stuff and not

I used this wrap on our Jeep and it worked rather well. I used the non-tape type as I didn't want the tube all sticky if I decided to remove it, I attached it using reflective tape.

edub370 · 10-02-2012, 01:52 PM

anyone have the torque app for their andriod that can display air inlet temps (maybe i can use my laptop and uprev?) to see if this would have any real world benefit

Thermal insulation is "omnidirectional." It impedes the transfer of heat in all directions.

I'm no expert, but it seems to me that a combination of reflective (reject as much as possible) and insulation (slow down any energy not reflected) would work best.

Looks great! Heatshield Products is definitely offers some of the highest quality heat control products on the market. I sell their products to industrial manufacturing companies that use specific products to help protect wiring etc. around their robotic TIG welders.

I'm not familiar with the UpRev software, but Inlet Air Temp (IAT) is part of the standard data that most cars have available. If IAT display is not a standard option in UpRev, let me know and I can provide the PID and scaling for manual configuration (assuming UpRev allows such).

-Edit-
Mode: 01
PID: 0F
Data: 1 hex byte
Data Range: 0-255 (dec)
Data Units: degrees C
Scaling: data - 40

Not sure what all this means. i'm more confused than a chameleon in a bag of skittles.

Wait until you find out how much it costs.

DR_ · 10-02-2012, 06:59 PM

I watch the IAT on my Dashhawk all the time. If you are moving and at WOT the temps with the Stillen G3 are pretty close to ambient. Even after a cool down lap on partial throttle at a track last weekend I still saw close to ambient.

I have dei reflect a gold wrap on my stillen intakes. I can't comment on the performance gain if any, I figured it certainly wouldn't hurt
