The proper set up for thermal siphon definitely seems to make a big difference. If that's properly set up steel vs aluminum probably doesn't matter. Although I couldn't find any black or silver aluminum banjo fittings which does matter so I went with steel.

On Brian's car we didn't have the turbo clocked enough and were using aluminum hose ends/banjo fittings. It ended up actually melting the rubber inside the braided hose. This happened at DGRR last year after pulling 24+ hrs to finish the car and tuning it the morning before leaving We swapped the hose end for a steel fitting and it survived the rest of the weekend and drive home no problem.

I could not find a -10 bender that would do a tight radius and allow me to make a hardline turbo drain that way. I ended up purchasing a -10 adapter to bolt to the bottom on the turbo then bought a -10 fitting with the pipe coming out of it and welded the flex joint from the stock turbo drain to it and modified a few other things as well. It was a PITA, especially with the engine in the car. I may remake it so it is a bit cleaner than what I have.

I am interested to see what you come up with.

What was the tightest you found? I've been looking at this one, but it's not a super tight radius.

If I can't make it work, I'll do a braided/fire sleeved flex line.

Here is a pic to show what I am talking about. Hope you don't mind me posting it here...

Not at all.

I never thought of logging MAP. I'll look into that. Maybe a stupid question, but what are the benefits of that?

Manifold air pressure (MAP) is the boost the engine is seeing. Would serve similarly to your peak hold, but a log of the entire run or however long you have logging set up for. It would especially be useful if you had some sort of catastrophic failure. You could also plot it vs rpm and show off how quickly your turbo spools

I have aluminum banjo fittings right now, it's the only thing I could use since I have very little clearance on the turbo to LIM and turbo to strut tower.

I know them feels

I haven't had any issues with anything melting. The EFR has two coolant ports on each side, and they tell you to hook the feed line on the lower port on one side and the return line on the top port of the opposite side, I assume that's what you're talking about with thermal siphoning.

Yea exactly. After the water pump is off the thermal affects will continue to pull coolant through the turbo if your supply port is lower than your return port.

That's a cool setup also. Are you going to use hard lines for the vacuum lines too? Right now I'm using nylon braided lines with AN fittings for my vacuum lines on the WGs, also wrapped in heat barrier.

Do you know if your lines are rated for vacuum? A lot of braided lines aren't, might not be a bad idea to check with a mitty vac.

Do you have a pic of that? I'd be interested to see how you have it set up. Are you using a 4 port solenoid for boost control? Using a vacuum manifold?

Hmmmm, that does sound like a good idea. I'll check on that to see if it has that capability. I've also thought about getting a turbo speed sensor.

I've thought about redoing the manifold, maybe in Schedule 40 next time and more evenly like yours and to fix the slant (the current mani has a 5 degree slant down towards the front of the car), but with the way this turbo is made I'm not sure I'd have much luck. If I do though, I'm going to see if I can get enough room to use either hard lines or AN.

OK I think my turbo has good thermal siphoning then.

I have no idea if they're rated for vacuum, I didn't even think to check.
