That looks pretty damn good Mike!! You gunna get it coated?

Gotcha, yea my plan is to do 4" all the way.

Thanks. Agreed. People doing long runner manifolds to "increase torque" amuse me. You know what makes torque down low? Getting into boost quicker

Yea I'll be getting it ceramic coated.

Yeah I always wondered too why people wouldn't want the shortest runners possible. I think mine are either the same length as yours or maybe 1/2" to an inch longer and my spool is ridiculous. It might be due to the turbo, or when I went to a slightly smaller IC, but I start boosting around 2K rpm and I hit full boost probably around 3300-3500. I wouldn't trade it for the world. It's what I've wanted for so long. My only problem is it hits so fast and so hard that I have to turn down the boost duty cycle in first, second and a little bit of third gears. But I figure that's a good problem to have lol.

^ Exactly, with my setup I make 2lbs of boost at 2k RPM stock motor and ports. New motor is HBP and we shall see the change as that motor is being built.

It is a turblown tdx61 with a 1.0 a/r, super short manifold, and short IC piping, and 4" DP.

I too find it comical all the people who want long manifolds to increase torque and spool.

Has anyone else encountered this? My turbo oil feed port is off center, and doesn't line up well with the fitting.

[RXtacy]

Small update.

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

What ECU are you running? Controlling boost via ECU or external boost controller?

Unfortunately he blew two motors in as many months. Not sure when you'll get to see some data on that setup.

Haha no worries, I like talking about rotaries almost as much as building them

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!

[Fendamonky]

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

[RENESISFD]

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

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

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.

[Pete_89T2]

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

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.
