Never heard of that, but I live in MD so I'm at around the same temps as you. I wish I had one of those laser temp gauges. For me, there is a VERY noticeable difference in temperature on the pipe and even the rubber couplers. Those are what got extremely hot during the summer. Now, they are almost as cold as the pipe.

About the TB running optimmaly on engine temp, I'm not sure about that but since it's controlled by the ECU (and let's assume that there's some sort of temp reader built into it), I would say that if it "noticed" colder/denser air coming into it, it would adjust the fuel map accordingly to push in more fuel. But again, that's just a theory for me.

 

yeah cant wait to wrap mine too.. hmmm..

 

Friday it's supposed to be a high of 55 and at night I would assume in the mid to high 40s around here. I'm going out driving with my friend and his Cobalt S/C. We're going to have some fun and maybe some vids to post ......that cold air chill is going to be sweet!

 

Hey WEB, got the scan gauge II so im gonna take my wrap off for a couple days and see how the temp is affected. Then when i put the wrap back on, i'll do it up nice with straps and even wraps!! Give me about a week or so.

 

thanks tcizzler, anxious to see your results.

 

Sounds good. I would expect some similar results but not exactly the same due to the difference in intakes and wrap. But yes, a temperature difference from unwrapped to wrapped would be good. Thanks tCizzler!

 

Just an update so far. at constant highway speeds, 45 and up. The intake temp is approx 2-6 degrees above ambient. In cooler temps like 50-60 its close to 2 degrees. And at temps like 80, its more like 5 or 6 degrees. And sitting at an idle it goes up to between 110 and 120 degrees, within 1.5 to 2 minutes.


I will take the wrap off probably this weekend and check then too.

 

bump for updates

 

I don't have the scan gauge, but it was about 55-60 degrees around here the past 2 days and after about 30 minutes at around 80 mph, I pulled over and the rubber coupler on the THROTTLE BODY was cold! The pipe where the MAF sensor is exposed on mine was nice and chilled and the front coupler was very cold. I think it's doing it's job. TCizzler, hoping for some good numbers from you.

 

I want my eBay intake ASAP!!! lol I need to do this mod. Should go nicely with my nitrous I hope.

 

Dry or wet shot?

 

Wet

 

Ok so heres what i got:
All ambient temps were measured with the cars own outside temp reading. And my setup has ram air.

With wrap:
Highways speeds- temps were consistently 2-5 degrees above ambient

City driving- 5 to 15 degrees above ambient, and at a stop it would go to approx 110 after 1.5 to 2 minutes, once moving again it would drop back down to normal very fast

Without wrap:
Highway speeds- temps were consistently the same as ambient or a degree lower

City driving- 15 to 20 degrees above ambient, and at a stop it would go to approx 110 after just 45-60 seconds

On the highway, the wrap seems to have no effect, if anything it keeps the air 2 degrees warmer. However in the city is were this stuff shines. It keeps the intake temps down while in heavy traffic or stopped at lights. I felt no performance gains whatsoever either way. But i did notice a huge difference in engine bay temps.

Without the wrap, i could open the hood and stand back and feel the heat pouring out, but with the wrap i could open the hood and put my face over the engine bay and it was just warm.And also with the wrap on, the piping was COLD, and w/o the wrap it was HOT.

Summary:
Highway: No effect
City: Fantastic
No performance (HP, courtesy of the butt dyno) gains either way. It just ran a lot cooler with the wrap.

Overall: I will put it back on mainly just to keep engine bay temps down, It may prolong the life of some heat sensitive parts.

 

Good research and follow up. Yeah, I've noticed that it's mainly to reduce engine bay temps and it helps the engine run a hair cooler for me. My needle drops as it hits idle just a bit.

So, I guess in an overall look, it's good for engine temp reduction and city driving, but there's no real gain in HP. I wasn't expecting any huge gain, if any, but I WAS expecting maybe 1-3 hp just from the colder air. Nothing noticeable but something I guess. OH well. Looks better wrapped and blacked out in my opinion.

 

Looks good, and this may help the supercharger guys, since some say that beacause the aftermarket header, the heat gets to the S/C seals. THEY SAY! I'm not Saying this! Just read it here.

 

Better idea for those guys would be to jet coat the headers. It is an internal and exterior coating of ceramic spray that retains much more heat than the heat wrap.

 

i have heat wrap around my k&n typhoon, and it works great id be driving highway then get off pop the hood and touch it and it was cool. Highly recomend it, just make sure you keep the wrap closer to the throtle body seeing as its hottest down there...

 

^^I've got the same. Mine's tightly wrapped from TB to filter all the way into the fender. Works great

 

nice research

 

ok yeah, the heat wrap helps to keep the temp down. but there is one problem. Headers get extremely hot. the heat wrap makes the temp on the outside of the header cooler we can all agree on that. but the inside temp of the header with the wrap will be much MUCH MUCH higher, which is a good HP gain but...I said BUT it is bad on the header itself. it is much worse for cast iron manifold. and warrantees will be voided by the manufacture if you wrap your headers. It will get soo hot inside the header that it could turn to molten and bamm a hole in your header. cracks are common too after prolong use of headers.
around the intake and what not good idea though. protecting your other hoses would be good too.
Headers should bet jet coated, inside and out
