Highest temperature at the start of the headers shold be about half that, so competent in that respect. DOH, just noticed it is only 2000F not C.

I need enough to wrap a set of headers trying to remember if it was 25ft x 2 or 50ft x 2. Cool it Thermotek was what I used, but there is no temperature data on it.

DEI stuff fell apart - it is only rated to 1500F it seems.

T-uk will find out the lengths.

This is the stuff I used - got it from Falkland, think I'll continue with it since it is 2000F also.

The DEI stuff was the stuff that fell apart and was 1500 so maybe this will be OK.

I was just speaking with someone regarding heat wrap, and they told me that it isn't really designed for turbo charged cars as the exhaust runs a lot hotter.

I was told that this might break the wrap down etc.

Anyone had any longterm breakdown of the wrap?

My stuff on the uppipe became very brittle indeed.

Any suggestion of alternatives?

John,

I'm looking around at the moment, and have found http://www.agriemach.com/product_inf...24b0dfe22dbacc, which is apparently guaranteed to be ok up to 2000 degrees, so that might be better.

What do you think?



Iain

The cooltek stuff can bear up to 750 degrees C, and this other one will handle prolonged temps up to 1090 degrees C (2000F)

I am probably gonna order 50ft of the stuff, but i only need 25ft of it.

Mail me off line if interested.

Cheers



Iain

I will pick up your mail a bit later on if you decide to send one

John... i believe the Thermotec stuff you have is the same stuff as on the Agriemach website that Iain posted anyway. They are listed on the Thermotec site as a distributer.... may be wrong tho.

That cool-it stuff seems to work OK. Had some on headers for a year or so, stayed in good condition (EGT boss in the collector & EGTs persuaded to go up to 840C sustained & 930ish peak with no obvious side effects. Well, not to the wrap anyway )

Does it matter if you use:

1" x 50ft or 2"x50ft?

I know obviously the 2" is thicker, but could you wrap the headers to much?!

nom

Depends on the headers, but 2" might get a bit tricky around the twisty bits!
Here's the state of cool-tech wrap after around 8,000 miles on a set of headers - .
I should point out I purposefully left the slip-joint out, because as John points out, this stuff is brittle, so the slip joint would ruin it pretty quick! But that should mean it's fine on a DP... I think the wrapping method used is very important. I took ages over it, all of it went on damp, & it was carefully 'stretched' into place (no wrinkles, etc). Seems to have done the job.
I just checked & it looks suspiciously like the same stuff that other companies use for turbo tea-cosys. And smells the same too when it gets hot the first time
