miko_supra Posted June 9, 2010 Share Posted June 9, 2010 I'm going to be wrapping my tubular manifold this weekend and could do with some pics so I can basically copy what others have successfully done! Mike Quote Link to comment Share on other sites More sharing options...

sdistc Posted June 9, 2010 Share Posted June 9, 2010 (edited) A little writeup from my efforts http://www.supraforums.com.au/forum/showpost.php?p=836719&postcount=337 I've been meaning to do this for some time now - I thought the benefits of insulating as many exhaust parts as possible was an excellent idea for a couple of reasons: 1) massive reductions in underbonnet temperatures (which without a vented bonnet have already resulted in some plastic parts melting!) 2) some increase in turbine spool speed. There has been a lot of conjecture and anecdotal suggestion that heat-wrapping leads to manifold cracking and/or faster deterioration of exhaust components. However, I have dealt with this possibility by initially purchasing a high quality thick stainless steel HKS manifold, then high-temperature ceramic coating it, then wrapping with 1" fibreglass-based heat-wrap, and finally sealing the cured wrap with high- temperature engine enamel.

Did you coat it yourself? If so what did you use? Edited June 9, 2010 by miko_supra (see edit history) Quote Link to comment Share on other sites More sharing options...
jevansio Posted June 9, 2010 Share Posted June 9, 2010 Couple of pics I took, I used both 1" & 2" thick wrap (just as I already had it), but in hindsight would use 1" all over as the manifold is quite a complicated shape Quote Link to comment Share on other sites More sharing options...

Did you wet yours when wrapping it? I've bought a load of 1" stuff to do it with. Quote Link to comment Share on other sites More sharing options...
sdistc Posted June 9, 2010 Share Posted June 9, 2010 Very nice, thanks! Did you coat it yourself? If so what did you use? Nope, I got the tuning shop to get it done. Can't recall what it is, but probably some generic high-temp coating. Quote Link to comment Share on other sites More sharing options...
sdistc Posted June 9, 2010 Share Posted June 9, 2010 Thanks Jay. Did you wet yours when wrapping it? I've bought a load of 1" stuff to do it with. You need to wet it to activate the fibreglass resin. Just don't rub your eyes. Quote Link to comment Share on other sites More sharing options...

TLicense Posted June 9, 2010 Share Posted June 9, 2010 You need to wet it to activate the fibreglass resin. Just don't rub your eyes. Hmmm, I'm pretty sure it doesn't have any resin in it. Certainly not the stuff I've been using anyway. Quote Link to comment Share on other sites More sharing options...
sdistc Posted June 9, 2010 Share Posted June 9, 2010 Hmmm, I'm pretty sure it doesn't have any resin in it. Certainly not the stuff I've been using anyway. haha yeah I had a quick check online and I now think I was totally talking out of my arse. Thanks for correcting my faulty understanding - wetting the wrap and stretching it while applying it simply means that it tightens when it dries.
