Header Wrap [Merged 3-8] thermal DEI headers exhaust

[c5chris]

Just use the stock heat shield if possible.

Heat wraps absorb condensation and keeps it in contact with your manifold. If you really want to do it right, have it ceramic coated.

EDIT: Since you have the wraps, might as well use it. Good luck

 

[TheClaw]

Yeah, I already spent $60 on wrap and ties I Mainly wanted it to wrap my WG dump tube, and to make sort of a sock to put over my oil filter since the dump tube dumps fairly close to it. Figured since I'd have extra I'd do the mani. The mani get's glowing hot after normal driving - can't be good for other stuff under the hood..

I'll try it and see how it goes.

 

[SinaiTSi]

I was told that if you wrap a cast exhaust manifold, it is more prone to cracking. I'd just put your heat shield on.

 

[TheClaw]

yeah, I'm not going to wrap it.. I will search for a heat shield.

I did wrap the dump tube, and upper part of the DP. I also made a "sleeve" for my oil filter since the dump tube exits fairly close to it.. Better safe than sorry.

Sounds like you're right on track.

Love where your head is at!

sorry to bring this back from the dead, but after installing my fmic, my tb elbow is HOT to the touch after driving..

congradulations would you like a cookie WTF

a cookie would be nice, but i was looking for something more along the lines of advice on how to remedy the problem..

ah now that you ask But seriously what i/c setup do you have? I know with mine my lower i/c pipe is super hot and my upper I can just grap and sit there for ever with it.

 

[RiceKiller_TSi]

Wrap your throttle body elbow with cool tape.

Definitely do not wrap your lower IC pipe as the heat you feel is the byproduct of the turbos' compression of the intake air which can easily exceed 300F . You'd want some of that heat to partially dissipate prior to the FMIC for maximum efficiency.

The upper pipes I'd insulate with material to reflect radiant heat (the shiney stuff) and maybe throw a phenolic spacer on the intake (proven to reduce heat transfer from the head to the manifold)

Yeah I don't have anything taped off on my car. I would rather wrap my manifold and turbo or whatever before I do that. I guess I should have been clearer. A good fmic should cool the charge enough to make the uicp semi warm but not hot enough to burn your skin.

well i have the agp setup.. even sometimes after the car has been sitting for a while the pipes are really hot.. its weird because before even after driving the piss out of the car the upper pipe would be cool to the touch.. now even after letting it sit its really hot.. i am pretty sure it has to do with under hood temps and not with any cooling problems with the front mount.. or could i be wrong?

 

[bytheway]

Yeah if no air is going through your FMIC, than your pipes are gonna start to get really hot from the engine bay temps. That's why you have to put a huge ass fan on your car when you dyno.

so has anyone actually done the 'cool tape' mod? any pics?

No, and for obvious reasons. Stuff that doesn't work doesn't get used.

 

[Defiant]

What would be more benificial, wrapping my fmic pipes with exhaust wrap (to hold in constant temperature),

You'll never have any such thing on a supercharged intake stream. The temps from the compressor will be all over the place, regardless what turns the compressor.

or "Cool Tape" (to reflect heat from engine off it)?

If any part of your motor's letting off enough heat to actually affect the intake stream, you have many more serious issues than intake temps.

how about the turbo that heats up to 1200*F? or the exhaust manifold that gets hot enough to melt off 1500*F paint? or the o2 housing? or the downpipe?

Those are why the heat shields were put on by the factory. The stock intake doesn't go near them, only another reason the car was built with a sidemount intercooler.

likely cause when not at WOT, the intake charge doesnt get cooled off enough by the slow air running through the fmic as opposed to 90mph winds. even worse with idle, since theres no air moving in the engine bay(or just the little bit provided by the fans) plus the fact metals transfer heat, and the tb is connected to the manifold which is bolted to the block.

even my ebay fmic made my upper ic piping ice cold after a nice boosting on I5 late night. after 20psi of goodness, pulled off and grabbed the piping after the fmic, cold as hell. popped the hood, grabbed the tb elbow pipe, cold. grabbed the tb, and it was starting to warm back up. within minutes all the fmic piping was warm again.

hmm.. that makes me think the cool tape would be a good idea ### most of my driving is stop light to stop light

 

[spoold]

I have a short routed FMIC and the LICP is less than 1.5" away from the downpipe. I wrapped the LICP in heat reflect tape. Whether its a benefit or a negative, i can not comment. I can only say that having my LIPC nearly inch away from the downpipe, heat reflect tape seemed to be an answer.

If i could do it over again i would not waste my time with it, i doubt the heatsoak from my downpipe/02 housing are enough to actually soak the already ambient charge from the compressor housing.

No, and for obvious reasons. Stuff that doesn't work doesn't get used.

Actually, Cool Tape works really well if you use it as it was intended. To reflect heat. A good use would be on a lower intercooler pipe that crosses right in front of the downpipe. And if you take a look under many race cars hoods, you will see heat shielding and tape and wrap galore. Heat is good in some areas (turbine housing) and bad in others (Alternator, IC pipes), so shielding or tape or whatever else is good when something that likes heat is really close to something that doesn't.

So to just say that it doesn't work with no real basis behind that is basically a shot in the dark assumption.
