i was thinking of trying to see if brake lines would be a better way for a better vacuum flow than hoses, especially the one from the wastegate to the turbo compressor. that hose runs hot , and i think with brake lines might do the trick since they wont flex and expand under high boost.

I use steel braided fuel lines for my vac lines. Works great and looks cool, just more expensive than the rubber crap.

no i'm talking about the hard bendable alumminum brake lines that you connect with fittings. but i know what you mean, those are as good as well.

that should work.......

It'd look nice, but its probably more trouble than its worth. I agree silicone isnt the best, so if i was you i would just use fuel hose or similar and common vac t's with small metal fastners, easy if you need to replace a section, and you dont have to bend pipe :-)

i use 5/16 fuel hose for most of my important vacuum lines. works pretty well, and it's a lot shiner and better looking than dull old sillicon vacuum hoses. if the 5/16 is too big, i just clamp it down good and tight. works for most stuff in my engine.

oh i as well have 5/16 fuel lines on all my vacuum lines, it's that i would think having alluminum brake lines will have a smoother flow than rubber hoses as like alluminum piping to an intercooler. it probably have a better effect. i for one could get these lines for cheap since i work at an auto parts store, if no one has tried this, i guess i'll be a 1st here. i'll give it a try and see if makes a difference.

Make sure whever you put this it won't be suseptible to bending or over time you will kink and break the line.

Russel, Aeroquip, and a company or two, make SS braided hose for vaccum, which would be your best bet I say.

Hey whats up. Ive been running 4an stainless lines for a couple of months now. Reason being is because my wastegate line got brittle and exploded. It is a little pricy and not all the fittings need real(compression) fittings(ie your boost controller box) But i have changed all my vac lines to stainless cause i could not trust the whole wire tie bull shit. true fit , positive pressure, no leaks, I would not go with the nylon lined hoses but actual rubber stainless 4an from earls is what i use. late mike
