i was wondering if its worth it to heat wrap my cai? cause i notice, at any given moment, the intake tube is very hot to souch and will burn you on touch. will i get any benifits from it?

also, is it better to plug the hole where the line goes from intake to the block? should i but a breather filter and plug that spot on the intake?

Holy $hiZZ, did you just read my comment on the k&n thread, i was looking for someone like you to help me out. YES, try the header heat wrap. I did it to my weapon R SRI and its seemed to make a huge difference, but i dont know if its all in my head, ya know how that goes! But i want some others to try it and see if it helps. I just wrapped mine on saturday so im not sure yet, i'll keep driving til the novelty wears off and see if im still impressed and then i'll know if it actually works. But until then, i wanna see if others will try it too, just to see.

And for your other question, about the oil breather. I would get a filter for it and plug the one on the intake. I've been trying, but its hard to find a filter that will fit there, because its so close to the head. Not sure if there is any true benefit other than looks, but some people say it helps the oil breathe better and last longer, others say it doesn't matter. I would do it just for looks, i personally don't think its a performance option.

didn't see ur post at all. lol. I got the idea from a friend. he had his heat wrapped on his eclipse. lol. I really wanna know though

The oil breather doesn't help more than the tube from the intake. Cooler temps from the intake are better to stablize oil consumption through burning and excessive heating. Continually breathing heated air from the engine bay will break oil down faster. Just keep the inlet tube from the intake to the valve cover.

Wow man you're evrywhere, just like me,lol. Thanks for the tip.

hahaha, that's what happens when you're on conference calls at work and bored. :rofl:

just say no to breather filters..

no. no. no. no. no. no. no. no. no. no. no. NO.

heat wrap cai? sure. :)

heat wrap CAI works...helps the car during long continuous drives, keeps CAI much much cooler....plus it looks kinda cool, expecially when ur intake is as scratched as mine

what do yall suggets to wrap it

Yeah whats good to use? Somebody up there said header wrap but thats like to keep heat in right? Ive seen some in a few car mags that like wrap around it and then you tie it like a shoe lace.

Not necessarily... Its just like any other insulation. It sustains temp. Whether it be hot or cold. Just like a insulated thermos. Hot coffee or cold soda. But anyway, i have header wrap on mine and yesterday i drove all the way home from work, about 35 miles. Which is stop and go, city and highway. And when i got home i immediately popped the hood and grabbed the intake. It was cool to the touch, not even the slightest bit warm,(room temp). So then i pulled back a little bit of insulation, and tada, the metal tubing was just as cool. It used to burn me even after letting it sit for 15-20 minutes. I'm a believer, but please someone else try it too. and maybe try it with other stuff that might work also... here are my pics

did you convert that to a cai?

similar.. its just a couple ram air hoses that i rigged out of dryer hose but work very well! The filter is actually made for ram air, and i ran the intake hose to the bumper where the filter normally goes on a true CAI

So, will this header wrapping work for CAIs during the winter much more efficiently? If it keeps the pipe cool now and it's still not that cold our, could we expect a frost build up on the pipe during the winter time? If so, as long as it's on the outside of the pipe, that would be awesome for highway driving. The engine would run so much more efficiently. How much, on average does this heat wrap cost? I would only wrap the main section of the pipe probobly, since the other half in in the fender.

I bought it online, but i can't remember what site. It was 20 bucks for 25', Or you can get it at some advance auto or auto zone for about 40 bucks. But i am not sure about the frost thing, thats an interesting question, i guess i'll just have to wait and see when the cold weather comes.

Yeah, I've seen actual intake heat shields sold but It's only a 3 foot section. Plus, you'd have to cut it around the MAF sensor and what not. I might just get the heat wrap and do it the hard way. Is yours self adhearing or does it need ties?

I'm going to get the graphite colored heat wrap with the stainless steel clasps. I'm keeping a dark smoke look under the hood and when i get my new header in the spring, i'm getting it jet coated smooth black to blend in. Trying to keep it all on the downlow even with the hood open. May paint the strut bar if I get around to it in the spring too.

Just finished ordering my black fiberglass heat wrap with stainless steel ties. I'll post pics after I'm done.

Mine was 2' wide and 25' long so i just wrapped it around the whole thing and went around the maf sensor. And mine doesn't have/need clamps, i just ran the last loop under the previous one (kinda like an invisible knot) and it holds perfect. Thats how i did it on my headers too.

Cool cool.......I'm going to make mine as neat as possible b/c I'm going to try and show my car in a few months after the Spring when I get some suspension work and my new header. I want it to look clean as hell. :P

Awesome, my car isn't much for show, its too hard to keep nice. I live on a gravel dusty road, so as soon as i wash it and drive away its filthy again, so i gave up with giving it the clean look. But definately post them pics when you get it

How long have you had the ram air kit on for. Have you driven through heavy rain yet. I have a ram air kit but do not know wher to put it on my SWR.

I've had it for several months, and yes through very heavy rain. No problems whatsoever. I assume by SWR, you mean secret weapon R, If so the filter has an adapter on the end that i clamped a hose to and ran it down through the fender wall to my front bumper grille insert, look....

Go to Lowe's..


In the pipe insulation area, buy "Frost king pipe insulation wrap"... Which is a roll of sticky insulation wrap that's about 1/4" thick with an aluminum-shielded side. Cost me about $5.

Wrap the CAI in all parts exposed to the engine bay. Voila' ! Now your CAI has an R-value of 2 or more.

I want one that is not sticky, for when I get it off, it will not look like Gum or something like that. Maybe buy one that is with clips.

DEI sells one at advanced auto ...kinda pricey...but its good stuff...keeps it cool....has to add a\few hp for when the enginge gets hot compared to without it

they make a black as well....with Stainless Steel Clamps...pretty

Looking good mpg wise maybe a few more, i dont wanna get too excited til i use the whole tank though.

Would this be effective say on a ZPI stage 0 kit? For the intake and charge pipe?

Probably, as long as the wrap can withstand the temps. It should say on the packaging what temps are ok. And for a little more money, there are website, can't remember where i saw them, but they have insulation wrap for headers with turbos. So that should work, just make sure it can take the heat

Yes, this heat wrap concept was designed for headers and high heat areas, but is almost always recommended for turbo applications. There should be a great increase in operation of the turbo when it is wrapped.

Sweet! So header wrap is ok on the intake pipes right? I did a quick ebay search and found some stuff including a universal turbo wrap which Ive seen on some cars. But yeah, I found that DEI stuff and it looks pretty nice.

I ordered my "header wrap" for my intake off ebay yesterday for 30$ shipped. Graphite black, 1''x 50'

this would be a good idea for a turbo, just like web said.....

smart....gotta give u credit on thinking of that

Thanks, but I can't take credit. It's been out for a while and I have a few friends that did it and could definately tell a difference in engine bay temps. Most are running short rams so any decrease in engine bay temps is a plus.

I actually meant on the turbo

but yeah the wrapping of any pipe is smart

Gottcha. Thanks.

I want to order some but I have neither a turbo or an intake... lol Im just really fascinated by this idea.

:rofl: :rofl:

wow....we both walked into that

Just checked, it was a false alarm. Same MPGs for me. The in take pipe has actually been numbingly cold lately (I pulled a little insulation to the side to check) since the temps have dropped to 50s and 60s

Well, that's good then. At least we know the heat wrap works. It'll probobly show more "improvement" in the winter time in means of a bit more hp. I can't wait for my wrap. Damn USPS sucks for tracking. They never update their tracking site until you receive it! I should get it either today or tomorrow but if they bring it today, i'm sure I'll have a note on my door saying that it has to be signed for and no one's home. That's crap. Just stick it in between the screen door or something! Stupid crap. I got my stainless steel clasps though. They are peerrrty

Finally got the intake wrapped. Just remember, when you work with fiberglass impregnated material, gloves are good but long sleeves would be great too. My arms itch like a b*t*h. Here's some pics.

From the throttle body up...

Engine shot...
http://img1.putfile.com/thumb/9/26513301882.jpg (http://www.putfile.com/pic.php?img=3474824)

It took me about 45 minutes b/c I tried to make it as tight, and bubble free as possible. I used a 2'' X 50' roll and had about 11-12 feet left. I like it better than the silver powder coat myself.

Looks great! Let us know how it feels. And also, wait until the engine is hot, after a long drive and feel the metal piping around the maf sensor that is showing, and see if its cold like mine.

Thanks.

Good deal. I'm going to be driving on the highway tonight for about 40 minutes so that should heat things up a bit.

I'll post back later.

I wish we can do the same to the trottle body, cause that piece is sure a GREAT heat absorbing piece. Touch it and you will see.

True true.


Just drove it for about 2 hours and the pipe feels cooler compared to what it would be otherwise. It was a lot of stop and go city traffic, so it wasn't cold, but definately not scalding hot. Hopefully Fall gets here soon so the temp drops to around 40-50 for highs. That will be great.

Well the temp went back up to about 80 for a couple days, really got me sick for a while, and the intake pipe was no longer cold, just cooler. So yeah i can't wait until fall when the highs are near 50-60 and see how it works then.

that black looks better then the other one...might have to go change now...

good job wrapping it...looks rather nice...

Thanks. I rewrapped it about 3-4 times b/c a bubble kept forming. But, the main pipe was the most hastle.

Nice temperature drop from just the intake wrap but I still had about 10 feet left. SSSoooo......I did my upper radiator hose and valve cover vent tube to the intake. Have you ever felt the radiator hose after driving for about 1 hour? That damn thing is fire hot. I wrapped it and the temperature in the engine was drastically cooler. The header was still pumping out some heat, but in the area around the intake , it was definately cooler. The coolant temperature was a little cooler as well. The needle dropped about 1/8 of an inch. I'm assuming close to 5 degrees. Here's some pics.

ok so could you tell me this..
1. any significant hp gains due to the resolution of the heat soak issues??
2. best product to wrap w/

Aight, horsepower gains I can't really say b/c I don't have it dynoed. Never have and might after I get my car completely finished next summer. I am assuming during the winter months the gain could be around 5-8 hp due to colder charges in the motor from the intake. Summer months I would say maybe 3-5 due to ambient heat already being an issue.

Best product:
I got mine off of ebay. I got a 2'' X 50' roll for 25$ shipped and I went to Advanced Auto to see if it was the same as the DEI (i think that's the company name) product......EXACTLY. I didn't want the cream colored one due to the fact that I'm trying to keep the car nice and dark inside and out.

Rules for working with heat wrap or any type of material impregnated with fiberglass:
#1...WEAR GLOVES
#2...WEAR LONG SLEEVES AND PANTS
#3...DUST MASK OR COMPERABLE PROTECTION FOR YOUR LUNGS (I have been coughing since yesterday b/c it itches.)

Here's an option off of ebay if you wish to buy it:

Here's the ties I used for the intake:

For the radiator hose and vent tube, I just got some thin wire, that comes in a roll. It's probobly about 18-20 gauge and comes in a spool. Probobly for about 3$ from Home Depot or something. Just tighten it enough to hold the wrap nice and snug, don't crush the hose.

Here's a site I went to, to see exactly how to wrap the pipes. I just didn't use the water techniqe b/c I figure the ties will be fine. I got a damp cloth and padded the intake wrap a bit, but nothing like they do in here. Mine works and is nice and tight.

**The girl at the end is quite hot too!!


Hope this helps anyone trying to do this. Good luck.

^ thanks for the help.. would def look into this...

Drove to work today, all highway, and cruising around 80. Intake pipe was COLD (it's about 63 here in the morning), radiator hose was hot, but not scalding, overall engine temp was cooler from an ambient feel, and temp gauge was running a hair cooler like yesterday. Overall, the heat wrap is working great.

Coolant Hose will get hot since the coolant running thru there is the one that passes the inside of the engine, and since you are beating on it, it's gonna be hot. The only thing that the wrap in the coolant hose is doing, is preventing the heat from the hose escape. So, yhea, it will be hot.

Yes I understand that, and the other advantage of the heat wrap on the upper hose is the fact that it shields it from the header. The ambient heat from the header will dryrot the out portion of the rubber hose much faster when exposed rather than wrapped. The inside of the hose will always be hot, even at idle, but the exterior portion of the rubber will be much cooler than it would when left exposed.

Update:

60 degrees according to the tC.

Rubber coupling on throttle body is cold and coupler near the fender was even colder. Aluminum pipe exposed (small section) was very cold. Radiator hose was hot but still able to be handled. Overall engine bay temp.......definately cooler.

^ wow it really works good then.. will try this next spring.. i guess since it;s gonna be cold already..

maybe someone with a scangauge or similar that reports Intake Air temp can take some readings before and after wrapping the intake. The other day mine read 100 degrees Farenheit (but it's hot and humid now in the 808 ;P)

^ here in nj its about in the 60's yeah the intakes dont get too hot not like last summer.. i felt my intake after driving for an hour and it;s not even hot at all (i have no heat wrap)

also i read somewhere that the TB oprimally runs on engine temp.. so i dunno if too much cold air (esp when it gets on the 30's here) would affect it.. can anyone comment on this??

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. :P

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 :clap: :clap:

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

Yeah, I think I said that somewhere in here but not sure. It's been argued and I've been on your side about the header and how it is not safe for the metal to be heated that hot for differenent intervals of time and then cooled. Needless to say, water being absorded from the wrap can cause pits and rust spots weakening the header in those areas and causing a blowout.

And yes, Jet Coat is the best way.................I'm with you 100%

where can u get ur header jet coated??? What kind of shop would do that, and how much would it usually cost??

So how is this working out for everybody?


^^^I just came back from El Paso. You ever hit up the Dezert Demonz racing?

http://www.hpcoatings.com/services/pricelist.aspx

http://www.thermaltechcoatings.com/pricing.htm

try any of those. Jet Hot is the pretty well known one. they dont list prices like the other links. there may be more out there but you get the idea

I was told by them when I asked for an estimate that it would run 165$ for a brand new header and their 3 year warranty. That's a great price and it's nothing compared to just spraying a ceramic heat paint on them. The use aluminum oxide on the inside and out to make the surface completely free of any debris. Then they spray it inside and out and bake the paint onto the headers so that it chemical bonds to the metal. Very good process.

Well its official for me too... Header wrap ruined my car. The headers got so hot that they melted my first cat from the inside out, I'm currently in discussions with the dealer as to whether they will cover it under warranty, they don't know about the heat wrap because i took it off before i took it to the dealer. They are trying to figure out the cause. If they think it was something i did they won't cover it. I doubt they can prove it was me but hopefully i don't have any problems, im going back in about an hour to talk the service manager as to what will be done. They think its because i took the heat shield off and that caused it to get really hot, but thats just BS so i'm gonna go argue. The heat shield i thought is just to prevent personal burns from a hot engine. Plus i only took the one off of the headers, not the one off the actual cat.

My advice to anyone with the wrap on the headers is to take it off ASAP to prevent possible damage, and expensive if not under warranty, (about $800).

WAIT... u had the stock header on with the wrap?

yep

Wow, now I know those catalitycs are weak. Better remove them , unless u have a BIG smog check near.

I really hope others read this and take the wrap off. Wrapping the intake pipe and radiator hoses is all that header wrap is good for b/c it won't damage them. It works great for them and won't damage them b/c it's repelling the heat and not working on keeping it in. Even aftermarket headers are damaged by heat wrap and it's not just a stock header problem.

Sorry to hear bro. Good luck with the replacements.

tCizzler: What was the outcome of the dealer visit? Good hopefully?

No!! they haven't called me back yet, Its total BS, i'm gonna give it til tomorrow, because that'll be a week. And then i'm gonna raise hell if they don't call me by then. I'll keep everyone up to date

Well they finally called me yesterday and decided to replace it for me. They even did it this morning within about an hour of dropping it off but i have to wait til i'm done at work to pick it up. Also i have to replace the spark plugs because they are chalk white from running so hot. Oh well atleast i didn't have to pay for the cat. Not sure if you guys knew but the header exhaust manifold and the cat are the same piece. So basically i got new "factory" headers too!!

Yeah, well....the preCAT is on the header.........main CAT is under car.

At least they changed it all up for you. NO MORE HEAT WRAP ON HEADERS!....Jet Coat them.

^^ No thanks, i learned my lesson, jet coating does the same thing, it sends the heat through the pipes and thats what burnt up my cat. I'm just leaving well enough alone.

The jet coat is good because it doesn't cause excess moisture and heat to break down the metal and cause cracks and other damage to the manifold, but it still puts ALL the extra heat into the rest of the system.

Not really though. The jet coating is inside AND outside. It heat coats and seals the inside of the pipes as well as the outside. The header wrap only traps the heat on the outside. Jet coated headers last longer and even give you a 3 year warranty against cracking and damage to the header if you send it to them to coat brand new. I talked to them and they sent out the brochures and all was stated in there.

You wouldn't coat a stock manifold though............only an after market CAT-delete header.

jet hot coatings are designed for cat-less exhaust manifold/headers

the heat placed inside the exhaust manifold from it being so thick walled, and having wrapping, would easily fry a cat....

Ahh.. Gotcha. Web and 3min3m2
