Do Exhaust Wraps really work?

[Memphis Raines]

It's always been a staple topic at my suking garage mechanics so I'm wondering if they really do work.



I guess it is pretty obvious that it may significantly help reduce heat in the engine bay but what other performance benefits can it possibly offer?

[niky]

Heat yes... performance... not really much... supposedly provides better scavenging, but any gains, from what I've seen, are minimal. It's worth doing for the heat alone, though.

[flakez]

yup, laking tulong against heat. plus mas malinis tignan headers lalo na kung yung headers mo eh kinakalawang. hehehe

IMO, it is better to have your exhaust manifold PnP'd or extrude hone'd first and get a good ceramic coat done altogether. Then if you want to use heat wraps for less underhood temps you can use that as well.

[rion]

what are those wraps made of?

Imo, it doesn't look malinis, parang old engine mummified. hehe...

how about this? do this really work?



or will break instead?

[niky]

I forget.. asbestos, I think?

The intake manifold cooler is only for drag racing... you use it to cool down the intake manifold between runs... by the end of the quarter mile, your manifold is hot again...

Besides, stopping on the road and opening your hood every five minutes just to put a bag of ice in is silly.

Product Description from Design Engineering, Inc.

The first step in controlling under hood temperatures is to use DEI's exhaust wrap. This product is designed to keep heat in the exhaust and evacuate it out of the engine compartment. Wrapping your headers will reduce under hood temperatures by up to 50% while providing additional horsepower, engine protection and passenger comfort. All exhaust and header wraps are not alike! We start with a hi-temp fiberglass composite material then add a proprietary coating to enhance heat retention and expand durability. We are also the only manufacturer to add 1/4" guidelines to the exhaust wrap to ensure proper installation without the guess work.

* Reduce under hood temperatures a realistic 50%
* Improves horsepower
* Only exhaust wrap with installation guide lines
* Added durability and heat retention

hehe... silly nga.

I have no idea, puwede e-apply yung cloth wrap sa fiber glass...

thanks.

My mechanic kept mentioning before that it's made of 'non-asbestos' material. They often refer to it as thermal wrapping. He also claimed that it can reduce at least 50% of engine bay heat and since it lowers intake temps so it can give more Hp.

Yup it does look like a mummified exhaust system but it sure ain't medical gauze bandages hehehe.

Hmmm... possibly health reasons... though having fluffy bits of fiberglass entering your lungs when you clean the engine bay ain't exactly healthy.

Did try copper-based wrap before... but it didn't work as well as the fiber-based ones at capping heat... though we didn't dyno-test it for any effects on scavenging (it might have been better... who knows?)

hehehe that's the time you have to coat it.. no more lung cancer :bwahaha:

I'm tempted. I actually want interior ceramic coating, but I don't know any local shop that can actually do that.

[rion]

come to think of it, I think this is beneficial to vans. some vans do have a very hot seat on the front. I remember a van from a friend, parang niluluto na ang puwet ko.

^^^ That's right :exclaim: No more hot butts and the aircon won't have to work overtime.

while you're at it might as well PnP the exhaust manifold hehe.. that's another trip to the dyno though

i think this one can be helpful too

it's a heat screen radiant matting.

[speedyfix]

thermotec heat wraps are available in the shop copper and black colors and 1 and 2 inch widths available.

[rion]

as I was reading the "Yellow Book"



it includes about thermal wraps.

[daimaoh]

i'm not sure about the performance but definitely yes on heat reduction.

it's a must for modified headers if you don't have a heat shield... unless you want your electricals to fry.

[[archie]]

thermal wraps are more for the stainless steel headers. mabilis kasi maginit stainless kesa sa black iron. the problem naman with black iron, bilis kalawang. hehehe

HTH
