i recently put a turbo kit on my tc and im having another big problem. my high performance vacuum lines keep getting too hot then flattening!!!! im trying to keep the heat down, so i heat wrapped the manifold, downpipe, and wastegate dump. still no luck. the lines arent even close to the turbo. i bought lines on ebay, the only thing i bought cheap and is the only thing failing! so im wondering what are some good vacuum lines that can withstand a good amount of heat??

they sell this stuff at Advance auto parts

 

go get 3/16" heater hose at advance auto parts

stop using the phrase "high performance"

 

These sound like they are failing due to the vacuum. I have used cheap line before but quickly upgraded to fuel line which works great.

 

This!!! Lol can I see what's so high performance? Lol

 

ive never had this problem

 

silicone hoses= fail!
the vac lines they sell at any local auto store/ hardware store work perfect!

 

well i was just sayin high performance cuz thats what they were called! and thanks for the input

 

Are you running engine management now? If not I'm sure this could be the cause of it, how high are you're EGT's?

 

mount the vac block outside the engine bay

 

Where in the trunk!? Lol. Just reroute the hoses better that they don't touch whatever is melting the hoses.

glove box, under the glove box, etc. did it for this exact reason so ish dont melt

 

The longer the vacuum hoses the less accurate they are. Or so i heard.

under the glove box there's a panel that pops off. my fic is mounted to the outside of that(facing the ground). and the vac block on the reverse side (hides when you attach the panel).

my wastegate is to the turbo, and the blow off is t'd off up by the throttle body. so the ac block is used for boost gauge and fic at the moment
