lets say you run your vacuum lines to your wastegate and such...do you cover them with anything? zip tie them out of the way...what? im looking for ideas to PREVENT melting and popping my motor due to a overboost..

 

I recently replaced one of my age old stainless braided lines that came with my greddy wastegate because it developed a leak (bullet proof my *** ) I used some good silicon/viton hose I purchased a while back from speedmachine and wrapped it with an adhesive fiberglass insulation with aluminum coating. Its the stuff that comes in a sheet.

If I were to buy something for the purpose of covering lines, I'd get some of that thermal sleeving stuff. What I used works, but its hard to get the hose to bend after wards.

I also tie-wired it on. zip ties will get (and have gotten) brittle and cracked after only 3,000kms.


sheeting i used (similar to this prodcut, not this exact one however):

what I would probably use were I to buy it with this purpose in mind:

Not saying I'd buy them from speedmahince either. Just trying to show you what I mean
