My old school intercooler is getting hot right at the pipe that passes infront of the intake manifold so I was wondering if exhaust thermal wrap would do the trick in this situation??? The original old school hks kit came with thermal wrap I'm supposing for this exact reason so if anyone could just give me an idea of what to get that would be great. Here is what I'm looking at.

anyone?

 

damn no one??? Anyone use the stuff???

 

I've used the Thermo-Tec Thermoshield heat wrap. Its pretty good. Only problem is I find the adhesive doesn't stick all that well, at least to to smaller things like wire loom right near the downpipe.

Should work pretty well for IC piping though.



I've also contemplated using this : http://www.thermotec.com/products/full/14500/14500.html

I actually prefer the stuff from www.designengineering.com. Looks a little nicer, but costs a bit more.

 

thanks for the input I'll check em out right now! so this stuff will actually keep the contents inside cooler rather than keeping heat from excaping right???

 

Its designed to primarily protect against direct heat. So basically it keeps surrounding heat away from whatever it is protecting.

 

great! Thanks I just emailed them to see what they would recommend for this application. I have a pretty good idea but they are the experts I'll see what they tell me. Oh this is on the http://www.designengineering.com/ website. Thanks again man.

 

I have used the DEI stuff on two downpipes and have been very happy with it. Good stuff. You don't need to spring for the metal exhaust bands to hold the stuff on. Just get some SS hose clamps.

 

i used exhaust wrap on my Ic pies as well as my Dp and cold air setup. Works great. If you want to get mroe into it i tryed some hot water tank reflactant tape then put the other stuff over top. I am sure it didnt make much mroe difference but its the though that counts. i endorse it. i just hope you have a decent cold air intake so that the pipes dont heatsoak

 

Well I do have a pipe I made for cold air intake through where the water bottle was but descided against it because a) people said it wouldn't do much good and b) because I read that the reason the stock tid is bad is because of the s shape and it would be almost an s shape with the added cold air intake part I made. So right now I just have a custome 4" aluminum tid. I was thinking also of doing exactly what you said by putting the tape down first and then the wrap. What do you think??? hum.....starting to think I should at least try it with the cai setup.

I'm seriously looking into wrapping my dp and making getting a heatshield jacket for the turbo. After a drive everything in my engine bay is hot too the touch. I should note I dont have the stock turbo heatshields though.

 

I don't have the heat sheild either, some of it broke when taking it out and since it was such a bitch taking out I got pissed at it and threw the rest away.

 

i almost found ona a few cars that with the stock heat shielding that it felt hotter in the engine bay. wrapping the DP helps a lot with heat. And i would really reccomend a cold air intake for the turbo. I have one in the same place u mentioned. and have seen some sweet intake temps with everything wrapped like -7C and on a mild night boosting it doesnt myabe just barely get into + temps

 

nice! thanks for the info!

 

Is there any solution to the stock headers? I'd like to leave the aluminum heat shield off when I put my engine back in, and wrap the header in something... but it's a square box with a pipe out the side! How'm I supposed to get tape around that?

I'm sure a wrap does a better job of keeping in the heat than that stock thing...

My words exactly.

 

I had my uncle bend me a peice of 14guage Stainless and use it as my heat sheild, only 3 bolts, and my wiring harness thanks me.

 

Here's my deal on the CAI... its value is greatest on an N/A.. The reason being is that the MAIN source of heat to the air in a turbo system is the turbo, and not why you may think at first, yes the turbo is hot from the exhaust gases, but the intake is constantly being cooled from the air being drawn in.. the main source of heat in the system is the compression of the air by the turbocharger. Its not uncommon to see 300F temperatures after the turbocharger when you have 15+ psi of boost...

Yes colder air is denser, and you will be able to pack more air into the turbo system, however, Its my position that the longer, more restrictive intake path of a CAI will dcrease the efficiency of the turbo system to a degree that it offsets the added benifits of the cooler air charge. Just take a look at most high boost turbo guys setups... the filter is slapped right on the turbo. A high efficiency, low pressure drop intercooler will more than offset the het drawn in through the engine bay.

On an N/A, there is no compression of the air charge, therefor, the only heating the air charge should experience is the contact it has with the intake system before it enters the rotor housing (until it gets compressed by the rotor.. then you'r lookin at 700 + degrees inside the cylinder... so you can see why we want the coolest air charge possible going into the engine...

 

I ceramic coated my intake manifold and the IC pipes. After a drag run you could touch both with your hands.

 

For these two reasons right here I didn't put the cai on my car.

1. because the bends in the intake make the air flow more constrictive. I emagined sucking through a straight straw and then sucking through a curved S straw and would think that it would restrict it somewhat (maybe not alot) but if you are just packing in more dense are is this mod just canceling each other out???

2. I'm sure if a cold air intake was that great we would see them on every car out there with a turbo however the truth of the matter is, like you said, everyone with a big *** single turbo has the filter directly on the turbo. Now here is why I think that is though,

a) They have so much h/p anyways what is another 5 hp?
b) They have such big *** intercoolers that really they don't need it.
c) It would be way more constrictive than anything because with those big *** turbos they don't have afm either.

So in conclusion I have no idea what to do

 

I have my Air filter attached directly to my turbo. It's a big filter, about 7" long. I have a little heatshield that stops the hot air from my rad fan from reaching the air filter, that helped intake temps quite a bit.

Due to my FMIC piping I don't really have the room to make a CAI, so this was a good solution.
