Need help with melting wastegate lines

[16TT]

Hellion twin turbo setup with a boostleash. I'm having an ongoing problem with the nylon pushlock tubing in the wastegates (came with the boostleash) melting during dragstrip outings. I've wrapped the lines in high temperature tape, put high temp silicone over that and then wrapped all of the nearby exhaust with lavawrap. These lines continue to melt at the entry point to the wastegate (this is the 3rd time). Only happens at the dragstrip after successive runs. I'm now wondering if they could be melting from the inside? Anyone have this happen? I was thinking of some type of hardline, but don't know how difficult it would be. I searched for previous posts on this but couldn't locate anything. Any suggestions appreciated.

Look into this companies products. Select your size and material. Or zip tie lines away from hotside and headers. Mine melted as well when I first installed the kit as I have seen others with same problem. Been running kit for year and a half. https://www.amazon.com/Design-Engin...=automotive&sprefix=dei,automotive,162&sr=1-5

Been running my kit almost four years. Rubber vacuum lines wrapped in heat tape. Not one issue.

Not just you brother. I am currently experiencing melting lines with my top mount kit. I have the pushlock lines wrapped in a msd heat sleeve and the heat wrap...they melt quick. I also run a c02 tank for boost control. I am going to try ptfe lines now..I will let u know what happens.

Thanks for the responses. Dennis, what type of rubber hose is it? Are they running extremely close to the exhaust or O2 sensors? How are they secured to the wastegates? Thanks in advance.

I ran into that same issue and switched to 4an braided stainless steel.

Summit sells the 4an adapters and I used fast-turbo for the lines. Just measure your existing lines to see what lengths you need.

Thanks for that info. That looks like a solid setup and what I was picturing for hardlines. I'm thinking I could use something like that right off the wastegates and tie it into the rest of the nylon lines further away where they aren't affected by the heat.

My hard lines go all the way to the solenoid.

Standard vacuum line hoses from auto parts store wrapped in heat tape. I’ll see if i can’t get some pics.

if the lines are only melting where they are connected to the wastegate then it sounds like the wastegate is getting hot.

Ive always run auto parts store rubber lines without any issue, but boy those sure are nice! I might have to check that out.

Added dumps on the wastegate and hard lines throughout for my c02 tank and vacuum...had some serious melting issues.
