I doubt you will be able to heat wrap a std manifold ? Just buy a roll see how far it goes ? |

I think i used 20 metres of 2 inch wide wrap.... there wasnt much left at the end. I THINK it was 20 metres.. bare in mind how much you need varies greatly depending how wide it is. |

Is it worth heat wraping a decat if my manifold isnt heat wraped? And also what are the benefits from heat wraping, sorry for the steal________________________________________ cherry p1.....SOLD (regreting this)blaze p2.....why did i buy this SOLD Black p3 ![]() |

Not a lot of benefits really. I've done a standard manifold, and also a de-cat. The wrap on a standard manifold needed a lot of steel ties to hold it in place, because its so twisty its hard to get a nice tight wrap all the way round. I did the de-cat because the exhaust tunnel used to get red hot in my track car with the heat that came off of it. I would't bother doing it again, not for what the stuff costs. If it was cheaper I would consider it, but its pretty expensive stuff. There are also arguments for it keeping the heat in the engine which is believeable, as the manifold acts as a good radiator to get rid of the heat. ________________________________________ Oulton Park in a BTCC 306 vid 1Oulton Park in a BTCC 306 vid 2 Lap of the 'ring |

Its really not worth it, it can rust the manifold or catch fire and for not much benefit.Try here > http://www.camcoat.u-net.com/Exhausts.htm Cars like Aston Martin etc use these types of coatings and i know its more expensive the im sure the gains from it are much better. ________________________________________ Pug fee`ver,Pick a Bogey, buy a Pug.

Personally, I wouldn't wrap an exhaust manifold.There is evidence to suggest (as Pete points out) that the manifold does indeed act as a radiator and remove heat from the cylinder head. By wrapping it, you have insulated it and the heat stays in the cylinder head. This has been known to burn exhaust valves out prematurely. ![]() ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone ![]() |

There is also a lot of evidence showing reduced manifold life.Cracking can happen very quickly especially on SS manifolds. Also there is a risk of fire if the slightest of gaps appear in the wrap as the intense heat acts like a magnifying glass consentrating a spot of heat on what every it may be in the engine bay! I have looked into various heat wraps and plasma coatings etc and came across a lot of negatives on the heat wraps! ________________________________________ V6 Power!Faster I can go the better!

If it is so wrong then these coatings must be wrong too because they keep the temps in there? Why do so many ppl do it if it's so wrong ? Formula1 cars have the coatings an I consider my car on a par with one lol.________________________________________ 230bhp 205 gti6 |

coatings are a little different, they don't keep the heat in the metal as much, nor do they promote corrosion or fires.________________________________________ need a part number? get on here - http://public.servicebox.peugeot.comBring on the Trumpets. |

Q37. I have been told that I should not use exhaust wrap with my stainless steel manifold because it might corrode or even crack. Is this also true for your coating? - Here at Zircotec we have coated a significant number of stainless steel manifolds and exhaust parts without experiencing any problem. Our technical specialists confirm that stainless steel can corrode (very) quickly under certain conditions, though Zircotec's coatings serve to protect against this type of corrosion and cracking. Unprotected stainless steel can suffer very rapid intergranular corrosion in poorly controlled welds or where the material of construction is poor quality. There is also a little known phenomena called chloride stress corrosion cracking by which highly stressed parts, including those made of stainless steel (such as stainless steel exhaust manifolds) can undergo extremely rapid attack by chloride. This effect can be so pronounced that the stainless steel parts will appear to have just rotted away. The worry here is that the materials used in exhaust wrap can often contain chlorides, and these can be released when the exhaust wrap gets hot. Furthermore, many chemical cleaners and road contaminants that might get trapped in exhaust wrap do also contain chloride materials. In view of this, our technical specialists advise that exhaust wrap should not be used on stainless steel manifolds or exhaust systems. Whats very interesting is the last sentence. ________________________________________ |

If you can be bothered with the f**k on of getting the nanifold off and stuff then do it. I think its too much if a hassle on to notice no difference at all. I have a heat wrapped gti6 in my shead never been fitted since i wrapped it. I will hunt it out!________________________________________ Clicky: [url =http://www.306gti6.com]click here[/url] remove the space between [url & = |

Worth every penny u get wat u pay for. imo bearing in mind this is for proper motorsport and it is one of the best ways of keeping the exhaust cool. ________________________________________ |

I've done mine, because I didn't have a heatshield as standard (on the 1.8 with gti mani) so needed to protect the rest from the heat somehow![]() ![]() Big pain in the ass to do though, if you do it, wear protection, the fibre is extremely unhealthy, and apply it wet! ________________________________________ Team WheelwhoreTeam Limited Edition Astor 306 Francorchamps RIP Virtual Blue 208 GTi quote: I ![]() ![]() |

How are you keeping the exhaust cool? By wrapping it you are insulating it meaning that it will stay hotter. Also, if you wrap a manifold, then the downpipe will get hotter as a result due to the gases passing through the manifold are not releasing heat to the outside. In my humble opinion, I don't believe exhaust wrap is a good idea. ![]() ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone ![]() |
