Melting Wastegate Lines??

[Girvin]

Lately I've been having some problems with the vacuum/boost lines to my Tial 44mm. The lines dry out from the heat of the wastegate and eventually crack causing obvious boost leaks.


Just looking for some ideas from other external wastegate users out there that might help permanently fix the problem????

Use high quality silicone vacuum lines. Heat will have no effect on them.
The walls of silicone line should be twice as thick as the i.d., so it will not collapse under vacuum. The stuff they sell at autozone is junk.

If you get desperate you can always use this to wrap the lines in:
Design Engineering, Inc. - Cool-Tape

Stainless braided, teflon brake lines. They're cheap, easy to come by, and easy to use.

Paul, every time I see your vacuum setup I smile. On the compressor side is it an 1/8 NPT to -4AN fitting, then -4AN banjo's on the wastegates?

Yup, those are the size fitting and hose that I use. The banjo fitting and hoses are all made by Allstar Performance. I'm using the supplied Tial banjo bolts. And the 90* fitting on the compressor cover is by Aeroquip, but all fitting manufacturers have those (XRP, Earls, Russell, A1, etc).

I always have found Aeropquip to be better than Earl's, just my experience. I may have to copy you on that setup, minus the blingy manifold and extra wastegate.

A high quality silicone vacuum hose, will defently make a difference (as posted above, don't pick up the crap line they sell at your local auto parts store). Now to protect the the line further, a product I use that works great is the "heat sheath" from companies such as DEI, as seen below:

Design Engineering, Inc. - Heat Sheath - Hose/Line Sleeve

It's very lightweight, very flexable & supposed to prevent 90% of the radient heat. There are a couple other companies that make the same thing & they are all around the same price (believe the other brand I have is Heatshield Products).

I've had the same vacuum line on both my Tial44 ports (EBC) for the past 2 summers & they are still just as new looking/flexible as the day I installed them. I also use it on my coolent lines & oil feed & even being right beside the CHRA, it still doesn't show any signs of wear (the outer coating on the previous "fire sleeve" I used in this area did dry out & crack in this area).

Where can I get vacuum lines like that is what I meant.

You can get them from Summit Racing. You'll need to know which one you want, though.

Like I said in my post above, I got my lines from Allstar Performance. (page 5 of the Brake Systems & Accessories subsection)

-4 should work well for anyone - just measure to determine which lengths you need.

This? Brake hose kit is what you used?
hmm
Allstar Performance

Nope, right here -----> https://allstarperformance.com/16in-4-line-4-str-4-90-deg-all46402-16/

And the part number on the banjo fittings is an ALL50068.

Just did this setup which also includes hoses and T- fittings for the top ports (not shown) and everything cost me no more than 150.00 Love it! Thanks Paul!
