jakeep82 Posted June 5, 2012 Share Posted June 5, 2012 Well ive seen a few starlets and other jap cars with heat wrapping around manifold and the whole exhaust system ! Now my question is what are your pros and cons to heat wrapping or just leaving it ?ive read a few things on line people saying it is bad some saying it adds HP? If so where is best place to get it as there is thousands of different ones on line ? Cheers for any help ! Quote Link to post Share on other sites
The Toffinator Posted June 5, 2012 Share Posted June 5, 2012 Supposedly get better spool etc due to the increased velocity of exhaust gases, hot gases flow faster... Car will also be quieter inside and less "Droney" as there is less vibration.Downside are If not wrapped properly, hot spots can be created and parts can break, especially if cheap steel.I have personally never had a problem on an N/A, But turbo cars r are a lot hotter running, so make sure its good heatwrap!

td04 glanza Posted June 5, 2012 Share Posted June 5, 2012 Im also looking at this just now would be good to good one big thread with loads of views on this, Also would i be able to wrap it now after its been on for over a year and has some surface rust, but its a high quality zizco set-up i have.Thanks,allan Quote Link to post Share on other sites
jakeep82 Posted June 5, 2012 Author Share Posted June 5, 2012 I also have a zisco manifold thinking of doing my mani and full exhaust system ! What quality heat wrap can you get as there is loads online !! Has anybody had any problems with heat wrapping? Quote Link to post Share on other sites
The Toffinator Posted June 5, 2012 Share Posted June 5, 2012 Should be fine mate, but if i was you i would go over it all with scotchbrite to clean it off. Quote Link to post Share on other sites
The Toffinator Posted June 5, 2012 Share Posted June 5, 2012 (edited) And i have always used textile technoligies stuff, the g-force wrap on my n/a. Going for the magmawrap on the glanza.

jakeep82 Posted June 5, 2012 Author Share Posted June 5, 2012 ideal mate thats great help ! do you literally wrap it on and start your engine or do you have to get like a paste type thing ? Quote Link to post Share on other sites
morgey Posted June 5, 2012 Share Posted June 5, 2012 (edited) im in the process of wrapping my hks manifold for my 4age, I've heard you get better throttle responce, but the main reason im doing mine is you reduce under bonnet temperatures as i have itb's at the back of the bay and any air going to them passes directly over the manifold.it is a pain to do, but im getting there. got another roll on order from fensport. figured that they should have some fairly desent stuff since they mostly run turbo'd cars so should be fine for my n/aany tips for wrapping hit up youtube aswel ;) like soak it in water when wrapping it as it stretches when wet then shrinks and tightens when it drys Edited June 5, 2012 by morgey Quote Link to post Share on other sites
jakeep82 Posted June 5, 2012 Author Share Posted June 5, 2012 think ill have do a little bit of video watching on youtube and decide whether to do it or not ! how many meters do you think it would take to do mani decat and all exhaust etc !? Quote Link to post Share on other sites
Asad Posted June 5, 2012 Share Posted June 5, 2012 from what i understand it goes something like this...mani off...clean it up...unroll it and throw the heat wrap in a bucket of water...scratch your noggin and decide whats the best to start the wrap and which way your going to go (all manis vary)...start wrapping tightly and use tie clips to hold it down then the metal ties when your sure youve done it right....put the mani on start the car...the amount/length of smoke/steam varies but it will eventually wear off Quote Link to post Share on other sites
jakeep82 Posted June 5, 2012 Author Share Posted June 5, 2012 anyone managed to do the heat wrapping while the mani is still on the car or is it to fiddly to work around ? Quote Link to post Share on other sites
The Toffinator Posted June 5, 2012 Share Posted June 5, 2012 Would be a pain to do it on the car mate. I did my exhaust on the car and wish i didnt. i wont be this time around.I bought 30metres last time and i had loads left after doing my downpipe back. Quote Link to post Share on other sites
jakeep82 Posted June 5, 2012 Author Share Posted June 5, 2012 yeah looking at a few videos now think it would definatley be a lot less stressful and easier off the car !! Quote Link to post Share on other sites
morgey Posted June 5, 2012 Share Posted June 5, 2012 I've used about 7-8meters doing 2 runs on my mani, but its a lot longer than a turbo. heres a pic of mine.unfortunately the runners are so close together you can fit the wrap between them so i had to go past it and then come back over and now I've got the uneven wrapping on the 2nd runner. but theres nothing i can do about it :/ Quote Link to post Share on other sites
jakeep82 Posted June 5, 2012 Author Share Posted June 5, 2012 suppose would be best to get new gaskets when you take your mani off to ? Not looking to bad there mate is it back on your car yet? noticed any difference ? Quote Link to post Share on other sites
morgey Posted June 5, 2012 Share Posted June 5, 2012 cheers fellaits worth getting new ones just incase they get damaged etc on removing them, and not yet im waiting on some more wrap to get delivered hopefully on thursday i think. but this is a better manifold than my old one so ther'll be a big difference between them anyway so wont be able to comment on the wrap itself im affraid Quote Link to post Share on other sites
jakeep82 Posted June 5, 2012 Author Share Posted June 5, 2012 fair play mate was just reading on another forum about turbo blankets few people saying they can drop spool times by up to 250/500rpms !!Also a few others saying that they have done it to the whole of there exhaust underneath and as with driving in rain some times it ends out just falling off and shredding so had to wrip it off !

Banbury Glanza Posted June 5, 2012 Share Posted June 5, 2012 How many layers/times do you wrap it around the mani/exhaust ?? Quote Link to post Share on other sites
The Toffinator Posted June 5, 2012 Share Posted June 5, 2012 Once usually mate. And jake they must have wrapped it in kitchen roll as the stuff i used wasnt affected by anything for well over a year. Snow/Mud etc. Never looked much different or came off! Quote Link to post Share on other sites
jakeep82 Posted June 6, 2012 Author Share Posted June 6, 2012 suppose they were probably using cheap budget stuff so did flake off in the end!! Quote Link to post Share on other sites
jakeep82 Posted June 6, 2012 Author Share Posted June 6, 2012 Think i may buy all new gaskets for my mani some heat wrapping tape get it all off weld up the internal wastegate replace all gaskets and get rapping my manifold and exhaust ;) ! Quote Link to post Share on other sites
Amjad Posted June 9, 2012 Share Posted June 9, 2012 I used cheap ebay stuff and it's held up fine. About 30m on my Japspeed exhaust, rolled it on covering the previous roll around by 50% (see youtube videos)Make sure you use gloves and cover sleeves/legs as the fibreglass is a bitchMine pops like a mofo Quote Link to post Share on other sites
Flaminsam Posted June 9, 2012 Share Posted June 9, 2012 I use thermotec copper impregnated wrap at work. Use it on the wagons going to afgan. According the the packaging it increases scavenging in the cylinders by preventing the gas from cooling down and therfore slowing down.I can second that when fitting this stuff its itchy as hell and not nice stuff to work with. Also don't soak the wrap, it will go brittle when its cured and snap. Also best to use lock wire to secure it at equal intervals. One of the cons Is its expensive, one of the pro's it works. Probably better for N/A engines or wrapping after the turbo. The turbine in the turbo will slow the exhaust gasses anyway. Quote Link to post Share on other sites
Asad Posted June 9, 2012 Share Posted June 9, 2012 interesting, never heard of not soaking it..... Quote Link to post Share on other sites
Flaminsam Posted June 9, 2012 Share Posted June 9, 2012 yup specifically says it on the packaging. il see if i can find a pic of it somewhere. Quote Link to post Share on other sites
