Hi zthians..

Just wondering, would it be better to thermal wrap the extractor or thermal paint it..
Know where and what price would the range be for both?

tanks in advance... :)

I think thermal paint is neater, but it can get worn after a while.

This paint reduces heat from getting released to the engine bay, but it is still hot. Anyway, it is not the same as heat resistant paint.

How about getting paint+wrap combo? :lol:

yeah.. planning to thermal wrap too currently.. not gonna do both soulfly.. hahaha.. too much i think..

maverick warned me about taking into account that the extractor ("chap muk" brand) might crack having to withstand too much heat after thermal wrapping.. any comments on that?

not only the chap ayam. i even heard ppl commenting the same thing for the hotbits extractor.

else y not try heat shielding it like the mivec extractor concept. ;)

Or u can custom-make a piece of insulator and secure it above your extractor. Standard Proton engine got this insulator to cover the stock exhaust manifold, so when I changed to aftermarket extractor, I modded the original cover to fit with the new extractor.

is this cover really2 can 'cover' up the engine bay from the heat or not ?

by looking at it.. mivec thermal cover will not 100% shield the heat from extractor.. but i think its a good concept..

some says thermal wrappping extractor can cause it to crack coz heat is not released..
and a known fact is without over.. 100% heat will be release to engine bay which makes hot air will be sucked in air ram..

so.. mivec shield will at least do 50-50 for both lor... reduce risk of extractor cracking and reduce hot air in engine bay..

well.. unless u want to create a racing car off course.. :)

my thoughts exactly... dont really need to get those with high-end brands.. as long as it blocks (to a certain extent) then it should be ok....

i dont think the mivec concept (using the original extractor cover right?) works to block the heat from the extractor... I think it just "deflect" the heat away from the radiotor and air-cond compressor... it will still enter an open pod filter...

not for a race car purpose... Just hand itchy.. hahahaha... :P

I don't think OEM extractor cover will totally shield the engine area from extractor heat, but it's simple & keeps heat away from aircond compressor. Well, I don't feel any amount of heat insulation work can save ur open-pod airfilter from getting hot air, without endangering the engine heat getting trapped. If u really wanna a good & cheap way of dissipating heat from ur engine, the most crude way would be removing ur front grille & bumper, or if really crazy, remove ur front bonnet :lol:

don't buy at car accesories shop

better buy at hardware stores, much much cheaper i believe

I went asking around... RM80 for Arospeed thermal wrap... everywhere i go is the same...
RM60+- for installation (dont want to mention shop name) :blink: More expensive than I thought.. Or everyone is trying to potong me.. hahaha.. lazy to DIY ler...

Yeah.. I think Hardware store would be cheaper too.. must go rounding and look for hardware stores.. :)

it has always been said that heat from your extractor will kill your compressor fan... but then again.. 50% says yes... 50% says no... so some cars are ok where as other cars suffer problems..

I guess it must depend on cars.. some cars have wider gap between the extractor and compressor fan...

Hahaha... RM200 is just too crazy! Actually i think you can just go to any exhaust shop and ask them to take out the extractor for you... you balut yourself and then ask them to reinstall the extractor... cost should be a minimum then...

I will most propably be thermal wrapping it... but i think heatshield is better... too bad I cant find a heat shield for my car... and my original one doesnt suit the aftermarket extractor...

can DIY the heat shield... also, my mechanic says it is better to thermal wrap it until your exhaust muffler...

wow... then I will need quite a lot.. RM80 was for 7 meters of Arospeed Thermal Wraps.. Saw another brand which was RM40 or 50 for 4 meters of Hurricane Thermal Wraps..

But I cant wrap all the way.. need to do my piping first.. :P so for the time being I will only balut the extractor.. :)

I tried DIY the heatshield before.. failed.. hahaha.. the metal piece i cut was too small..

anyone know if powerzone extractors can be wrapped? It looks like regular galvanized steel...or what shops call piping putih...

will it crack or anyting if wrapped? can we DIY this...cuz my extractor is relatively easy to remove...Does the Thermal Wrap come with all the required clips to install it?

i remember reading from somewhere here that piping putih should be able to withstand heat better than those shiny ones.. (cant remember what its called)

and yes.. thermal wrap should come with all the clips required.. 4 or 5 i believe.. unless you are getting them from hardware shop or something.. :)

thermal wrapping your exhaust is not for the sake of shielding heat away from your open pods, radiators.. whatnots..
it's to keep the exhaust gas temperature as constant as possible throughout your exhaust system. this is to ensure there's no drop in exhaust gas velocity when it's exiting the system; you don't want to induce unnecessary backpressure, neither do you want to screw up the functions of the properly calculated extractor lengths that was designed to help 'suck' out exhaust gas from another cylinder.

the normal mild steel extractors would crack if thermal wrapped, just switch to stainless steel extractors and you'll be safe.


don't get confused between thermal wrapping and heat shielding guys
:)

he is correct guys

thermal wrapping the extractor does help prevent heat from released to the engine bay, but not that much. heatshield is still the best way to reduce the heat.

ooo... nice pointer there... get us back on track on the main purpose of thermal wrapping.. the difference of thermal wrapping and heat shielding differs greatly based on your explanation.. thermal wrapping for maintaining consistency IN exhaust system.. heat shielding to "separate" hot air from the extractor from filter.. so i guess probably should just do both.. :P

I am not DIY'ing on my extractor.. :) hate to say this but too plain lazy too... i feel bad but it is the truth..

alas.. this "should" be the end of my extractor story.. drove by a few shops today and everyone who looked at it says it is better not to thermal wrap my extractor (which looks a little "stainless steel" by the way) as it would most probably crack..

However.. ended up talking with one shop about changing the whole exhaust system (another el cheapo system for me) from extractor (one which can be wrapped) to the muffler and everything in between.. muHAhahAHAHhahahahaHAHah... NO! I must refrain!...

Pardon the final uncalled for laughter... its the 1-day Holiday kicking in.. :blink:
