I was wondering if anyone know how safe it was to have a downpipe near your fuel lines as long as there wraped up in exhaust wrap and heat shileding.

thanks.

my downpipe is close to my fuel lines... my downpipe is not wrapped but my fuel lines have a heat sheild around them, i have not had any problems...that and i pushed them as far away from the downpipe as possible (along with some heater hoses i replaced for longer ones to relocate as well), i have pics somewhere, i'll post later...

My downpipe is wrapped and my fuel lines are ss braided. I haven't had a problem yet. I have some other wires wrapped some other lines near it and all I can say is, the wrap doesn't hold too well. I think that is, because the turbo is very hot, because the downpipe stays pretty cool. However, it is holding up for now. I need to rewrap them, soon.

Yet another reason why I went remote turbo....

Just remember that heat in general toward anything rubber or plastic is very bad. Be sure to keep everything away from the heat AND try to use header wrap where necessary.

I have heat wrap but the down pipe is about a half inch from the black box box. (yes I forgot what it was my eyes go into tunnel vison while im working) but the collant lines are also close. does anyone know of a way to keep the heat down. (besides wrap)?

umm, you could try wiring up one of those mini computer fans. like the 4--5 in ones.they may be small but they can push some air around. Just a thought but it might actually work really well. I just might try it.

Tin or aluminum can be used with excellent results. Old license plates can actually make great heat shields. Ever notice how many of the Asian cars have tin shielding welded to the OE exhaust pipes? It works. All you need to do is leave a slight gap between the shield and the pipe and you can reduce temps around the pipe significantly.

Heated fuel line isn't such a problem if the line you're heating is metal, and your vapor purge system (charcoal can) is intact. The biggest problem with hot fuel is the loss of density, and that the ecm doesn't actually know how to compensate for changes in fuel temp. I'd be more worried about the coolant hoses since I've seen them bake and crack from heat on non turbo cars.

Ceramic coating is probably the best and most proper way to stop heat without using some sort of rigged up heat shielding. Might cost a bit but will also help the turbo spool up and keep the heat in the exhaust up to temp for higher flow.

thanks for the imput guys
