There's a reason I have yet to install it...the heat needs to get under control for track applications. I'm sure for street its "OK" but for track when we are WOT for long periods of time...this is a problem. .
The cast manifold and layout does give you the opportunity to minimise the amount of exhaust heat that makes its way back into the engine bay .... hopefully that will help your situation!
Update :
One of the manifold setups is up and running . Results (virtual dyno) are not as good as I would hope but owner is very happy with how it drives . A few things are holding it back , (EDIT catalytic converter) tired engine, knockoff turbo , lack of EBC being the main ones.
Meanwhile I've discovered an issue with my setup that people need to be aware of. In the cold temps we are having atm (around 10C) there is a tendency for mild boost creep. Was going from 10 to 10.9 at 8000. I've got it under control now by cutting the EBC at around 7000 rpm. For most street setups this is highly unlikely to happen but could when exhaust is large and freeflow. Using the 1.01AR for a race setup should eliminate the possibility in that situation.

Bending plastic sucks (Installing ducting). Haha. I'll let you know what happened this weekend. If the car survives, system is going on and I'll sort out the heat as we go. Those are good numbers! I'll be using non-counterfeit hardware and sticking as close to your recommendations at possible. Cheap parts already cost me once (Counterfeit NGK plugs) which ended with me getting towed off track when the electrode pretended to be an apex seal and exit stage right.
Good news...the ducting actually worked! Really well too! The air temps were about 107F and the car never saw anything above 208F while flogging at COTA.
Then...about a quart of oil flew out of somewhere and that ended my second day for the rest of the weekend. I'm still not sure where it's coming from but the oil definitely sprayed up and out over the windshield thru the hood vents with extreme efficiency...so I suppose I can check off the ducting as tested OK.
As soon as I get over my oil puddles pity party, I'll send off my spare keg to get rebuilt and studded. Then look under the hood to figure out what happened. Followed by fitting up the turbo system and finishing the fab work to get it in. Then swap the current oily mess for the rebuilt keg.
I'm not looking forward to any of it since I don't have a garage to work in and it's hot as hell right now. But the goal is to be back up by a Sept Track Night in America event so I can shake the car down. Next COTA attempt is in November.
Time to get back to margaritas for breakfast and contemplating if I want to unhitch the trailer yet.
After reading that I changed the design of my can and increased the size of the hoses coming to and from it. I've not managed to get any oil in it since!
Catch can? Pfft...I have always vented to atmo and wipe the area down. This was definitely not related to that I believe. Oddly the dipstick was popped out, as if pressure pushed it out. When I revved white smoke came out of the filter that vents. Didn't see any oil squirting, but then I saw some oil dripping from above the eshaft down. Like it's under the intake manifold somewhere.
I suppose I should install a catch can based on your link as boost will need one.

But how big is the vent hose ? Also .... if your dipstick popped out ........ it's definitely related !
Oil coming out of the front seal could be just a symptom of pressurising the sump.

There's no hose, just a filter that goes over the nipple with a clamp. Haha. Raw ******* the engine bay.
Yeah I was thinking it's related. I just replaced the front seal. I don't think that was it. But I suppose I could double check. I was going to pull off the UIM and look around after I hose out the oil. What could have created so much pressure? How?

Blowby creates the pressure and a boosted engine has even more!
Doesn't matter if it was a filter or a hose , you are still tryig to force too much air through a 6mm hole(oil filler vent hole size). Is that where the filter is ?

Yep. That's where the filter is. Oil filler vent hole.

You need a bigger hole! I use two holes ..... that vent hole plus the extra vent hole you get on the 2006 on filler tube. But for a track car you might want to stick a bigger hole in the from cover of the new engine. Re-read that link!
or think it through to do it properly; the vent/oil flange on the middle iron is 1” ID or so. There are any number of better ways to divert to a catch can, including cutting the section to the oil filler cap off and clamping a silicone tee there instead with the tee going to a catch can with a large diameter tube/hose.
small hoses/holes = higher velocity and greatly increases carrying oil where you don’t want it to go.
.
Are you saying the car puked oil out of the vent hole? Because it appears to be from under the UIM and above the front eshaft area considering all the oil.
if it’s not getting out fast enough it could overpressure the sump to blow out somewhere else, but you obviously need to investigate and figure out where it came from and assess for any possible damage or need for repair(s).

This is more like it...I would like to subscribe to this newsletter.
While I'm sure that idea will work ....kinda ugly ?
:facepalm:
how about buying a tee the same color as that section of the manifold, with the tee section facing to the rear, run the hose underneath the UIM back to the firewall, and then over to the catch can? (would need to verify, just by memory).
you know I got rid of that entire underneath part of the UIM on my NA setup, right?
.
there are any number of ways to handle it, but for me to choose the easy way for the average forum bear to address it; a common response when presenting what would be the more elegant or preferred method in my own mind’s eye, is not exactly a shocker.
more than happy to come down and lend a hand or two.

Do you have a picture of what this looks like cleaned up? Thanks!
Just as another thought. I was having a similar issue, dipstick popping, but no significant oil rejection...so perhaps not as bad as yours. I upgraded to a Mishimoto CC w/larger ports and larger venting lines ...from 5/16" IIRC to 10AN. Haven't had an issue since. Pre and post pics below.
Though it sounds like you may need even more venting flow capacity than this.
went back and looked and what I suggested likely won’t work. Because I was thinking the oil fill tube was round the last length of it, but the intake nipple doesn’t go straight in. It runs down the length, and protrudes out from the side, of round fill tube part. There are alternatives, but anyone who wants to discuss it should send me a pm or email.
Largest possible venting line is the answer though.
