Heat wrap?

[30psi 4agte]

mick can you get that stuff cheap????? what size are the sheets?

Im after some

[30psi 4agte]

this is just a pick of that new black / graphite heat wrap

mick can you get that stuff cheap????? what size are the sheets?

Im after some

sheet sizes are 700mm X 290MM or you can order 700mm X 580mm.
prices ill have to find the invoices, ill get back to you on it.

my old dump pipe was 316 grade and coated but not wrapped.

the new one is 304 grade and has been migged together. the reason i chose 304 is cause i didnt have much of a choice as 3,5 inch pipe and bends i couldnt get in 316 grade.

we work with stainless steel fabrication every day and 304 should ALWAYS be used for exhausts as 316 will work harden with heat and crack every time

stainless steel or ceramic coating first is the only way to use the wrap as it will hold condensation and steel components will last about 6 months and fall to pieces with RUST!

My experience is that the wrap works much better than the coating my engine sees prolonged periods of verry high load and underbonnet temps is a real issue melting many components along the way

i have wrapped stainless steel pipes and seems to work verry well, i also use basic aluminium shields all over the place too simple yet efective

other way round! coating works better than wrap. ive only used wrap if we didnt have time to get it coated before a race etc. if the alloy coating is done properly it works very well! hahaha as i get a bit done i get a good rate. my parents have one of the big hooded 6 burners BBQ's and the enamel was getting so so. i got them to strip it and coat inside and out of hood and base and then i changed all the bolts and screews to stainless and the heating and grill bars to stainless and made a stainless tube opening handle!lol
instead of needing 3 burners on full to get it to hold max temp, it only uses 2 buners on half to do the same thing and saves a shit load on gas and looks hot!
all up it cost me a grand total of $300 which i reckon is good money for a top BBQ.

hahaha just thought id share!

i dont know from a performance or internal gas flow point of view or exactly what coating was used for this comparison but as far as heat radiation goes i can hold my hand an inch away from my wrapped dump pipe and tube manifold while the car is at full noise on the dyno

when i used to play with V8's i got all my headders coated and thay used to poke out a lot more heat .... couldent get your hand anywhere near them at full noise

so just going off real observations

[kingmick]

the coating keeps more heat inside as thermal energy. the radiated heat dosnt really matter unless you have a restriced flow engine bay so the heat cant get out, then the glass lagging helps.

You can get sheets of that ALC heat sheld for $45 off ebay. $10-15 delivery if i remember rightly.

Think i might get some of the heat sheilding to protect the area and later some coating for dumps and perhaps manifolds. I got a quote form jet-hot. They said $66 per 30cm of tubing on the dumbs and 2-300 for the manifolds. Just so every one else has an idea of what they're up for

[ReQuieM]

Also forgot to mention you need the 'extreme' or what ever its called if your running about 8PSI as the aluminum in the coating has a tendency to melt/oxidise in 'high' boost applications.

I was told this heat wrap stuff isn't that good an idea as they absorb oil fumes and dirt etc..after a while...catching on fire.

THats why you spray them with a hi temp paint to seal them.

I tend to agree that the wrap will fall apart and become very brittle with sustained high temps 600+ degrees cel.

Yet on a mid 20 degree day and giving my car a bootfull for a decent time frame, i havent seen a reading above 400 degrees cel. from the turbine housing.

So even for a full house street car it would be fine. I'd say different story on the track though.

most cases its fine! main prob is when you spill oil on it or it gets squirted with oil! trick is to paint it with high temp paint after you put it on and it dry's, then the oil cant get in.

p.s sorry blacksupra just saw you wrote that!

Kingmick: I LOVE that your sig. I think I start laughing every time I read it! lol

ReQuiem,
I have the ACL heat shielding on my manifold and dump pipe. Its not that easy to bend but if you take your time you can still get it pretty neat. Its the best heat shield I've seen.
In my opinion, ceramic coating together with this heat shield is the answer, well it was for me at least....

This is the pic of it on my 3T GTE

anyone know a price for this stuff ??????????????????
