Astral Ace Posted September 17, 2007 Share Posted September 17, 2007 I am going to wrap my headers. I know I could spray the silicone stuff, but I got the wrap for cheap. It's high quality, and I trust my friend. Well, I was thinking if I just wrap it with maybe a minimal over lap or just leave a gap of maybe half an inch or an inch... I'm not sure if it would help leaving the gaps or would that cause hot spots or what? I don't think I'll get much moisture around the wrapped headers because it stays dry here. Well, some what. Atleast last year it did... I saw somewhere that you can spray the wrap with a high heat silicone to block out the moisture. (probably the same stuff to just spray right on the headers...) Anyways, I really don't care about these headers that much so... Anyways, just fishing for some opinions. Quote Link to comment Share on other sites More sharing options...

jt1 Posted September 22, 2007 Share Posted September 22, 2007 I wrapped a set of headers once. It seemed to help the car some, although we didn't dyno it. Underhood temp went down, and you didn't burn your hands so easy working on the car when it was hot, so that was positive. I don't think leaving gaps would be a good idea, because the temp along the header would vary so at the wrapped/unwrapped areas. If I didn't have enough to do the whole header, I would divide it up, start wrapping the tubes closest to the head, and stop when I ran out. That where the tubes are hottest and the most heat lost. You are bound to have some overlap around bends, but on straight sections butting the wrap against the previous wrap should be fine. We didn't have a moisture problem, but it was on a pure race car that never saw street use. John Quote Link to comment Share on other sites More sharing options...
Astral Ace Posted September 23, 2007 Author Share Posted September 23, 2007 Having enough is not a problem, I've got 50 feet of it. I just wanted to get some feedback on a new take on a way it could be done. Quote Link to comment Share on other sites More sharing options...
DemonZ Posted September 23, 2007 Share Posted September 23, 2007 If it's mild steel the wrap will shorten it's life. Unlike SS which can take the heat. Quote Link to comment Share on other sites More sharing options...
