Small update.

Got started on doing hardlines for wastegate coolant. Will also be doing turbo coolant/oil in hardlines as well.

Your setup keeps getting sexier and sexier!!! Loving the hard lines for WG coolant :)

Yeah I didn't think it was that small at the time, but everyone is saying it's kinda small. I'm thinking about trying an 8374 for the next one since this one spools so fast.

I'm just putting in my Adaptronic, still trying to figure out how to set up everything to log EGTs and AFR and use those for running closed loop, well, AFR anyway. I've been using an APEX'i AVC-R, but I've thought about switching to the internal boost controller in the ECU. I really love the peak hold of the AVC-R though, I use it quite often since I try to keep my eyes on the road while in boost instead of watching the boost gauge lol. Although I should probably watch that too.

Yeah it's kinda tough to learn anything about your setup when your tuners keep blowing your engine lol. Poor guy.

What the hell is with that?! I've never seen that before.

That is awesome! I've been wanting to do at least AN fittings and lines on the turbo coolant lines, and do something for the WG coolant lines, but I'm loving these hard lines. Excellent work!

It looks like you are flattening out the tubing when making the bends. What bender and stainless are you using, also what wall thickness?

Thanks for the compliments on my build. I plan to replace the stock hardlines with -8 lines this winter under the car.

Has the wait time on the EFR line gotten better these days?

Adaptronic should be able to log MAP as well right?

Not sure, kinda annoyed by it.

What are you using now?

The supply line to the front wastegate was the first one I did. I think the first 90° bend off the wastegate flattened out a bit. I don't think it's enough to worry about, but good eye. I'm getting better as I go :lol:

I'm using the mastercool bender, and 1/4" .020 wall 316L stainless tubing.

That seems like the only one that flattened out. You can cheat and put it in the vise and squeeze it back into shape. It is best if you have plastic or aluminum jaws so you do not mar the stainless. Sometimes that works.

Nice work on the lines. It takes so much time but is worth it at the end.

Are you going to make a hardline turbo oil drain as well?

That's not a bad idea. I have the aluminum AN jaws that might work. I may give that a shot thanks :icon_tup:

Thanks, yea it does but I totally agree when it's done it looks so good. Maybe it reminds me of my childhood playing with these but who knows :rofl:

Yea I plan to do all the turbo lines in hardlines as well. I need to find a bender that can handle the -10 though.

Yeah I've heard it's gotten much better, don't have to wait near as long. Unfortunately I have to wait for the money though because the price has gone up a bit too lol. I don't know for sure yet if it can log MAP, I'll have to check on that.

Yeah I'd be annoyed too haha.

I'm just using rubber hose for the turbo coolant feed and return lines and have them wrapped in heat barrier, and I'm not running any cooling lines to my wastegates yet.

That hardline setup is sweet, what kind of fittings are you using and how does it seal up at each one, single or double flare?

Maybe the price increase has something to do with the availability :lol:

I would be surprised if it couldn't, and I would definitely want to log MAP.

Steel or aluminum fitting coming off the turbo? I've seen coolant feed lines melt several times now. Using steel fittings instead of aluminum and having it properly clocked for thermal siphoning seemed to alleviate that however.

Thanks. They're AN tube nuts and sleeves. Single 37° flare.

I have aluminum banjo fittings on my turbo, the anodizing is heat faded but they did not melt. I too have a good thermal siphon. I think that is something that is commonly overlooked when installing a turbo. The steel is a helluva lot cheaper though.


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.

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

Maybe lol, I have no idea. Now they offer 1800 degree and 2000 degree coatings as well, so I'll probably pay extra for that when the time comes haha.

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

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 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.

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.

^, yes, I use stainless hardline on the wastegates vacuum lines. I just do not have them pictured. This pic was taken after I blew my motor this year. I had 5k miles on the turbo setup and lines at the time. 70k mi on the stock motor.

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 :lol: 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 :rofl: We swapped the hose end for a steel fitting and it survived the rest of the weekend and drive home no problem.

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.

Not at all.

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 know them feels :lol:

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.

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?

^ This is the best I could find. I wanna redo it and make the lines shorter and use some different fitting to route the lines better and relocate the solenoid. Since I have the engine out this year I will get some pics but hopefully you will have yours done by then. Yes it is a 4 port.

this is a better pic showing the drain. I think it looks a bit crude and will probably try to make something a bit better and more professional looking.
