And by debating, he means he is debating on which "meat" he'll bring for us

The crew sent me a pic from testing this morning at WSIR:

Superlap front end received some spray paint.
Only difference otherwise is the new ginormo wing endplates from Singular Motorsports.

Underneath, it received a slew up upgrades from our previous Time Attack setup:
ID 1700cc injectors, DW300 pump on a standalone circuit.
LSx ignition coils
The above, give us the headroom for over 400whp on e85 out of the same EFR6258 turbo and Trackspeed Engineering hardware we run in Supermiata S1.

Xida Race Triple adjustable. 1400/600lb
Quaife QBE60G Sequential
3.6 or 3.3 Supermiata tuned OsGiken LSD depending on the track.
We're going to test a staggered setup since these front fenders don't clear 15x11" wheels: 245/275 Hoosier A7 on 15x10 and 15x11 949 Racing 6UL wheels.

Testing at WSIR yesterday we had trouble controlling PCV. Our previous setup was capped cold side, hot side vented to a Moroso catch can. Worked fine at 300whp/15psi with the 4W head. At ~24psi/400whp on the 6D head though, it would blow heavy oil laden vapor right through the separator and out the breather on the catch can. Lots of it. We played with a few different routing configs, restrictors, flipping sides. We only succeeded in covering the engine bay and left side of car (nice hood vents) in Amsoil 10W30. So today we tapped a -10 into the cold side of the pan, up front in the non-submerged portion. Ran that through a -10 hose to the Radium separator on the pax side firewall. Plugged both ports on the valve cover. Tapped new -10 port right behind oil filler cap and routed that to the separator. It seems that if you make enough boost even on a fresh engine, the slight positive positive crankcase pressure blows any vapor out the path of least resistance at fairly high velocity. So it never drops out of suspension despite several bust stop chicanes in the catch can. We measured 0/0/0/1% leakdown so the motor is bitchin. The strategy now is to let it blow the vapor through but make it lowest resistance path a big hose back to the front of the sump and not the breather. We have an alternate drain hose plumbed with a zero cracking pressure roll over valve made for off road fuel systems. We'll try it first without the check valve. Through all this, the engine never burned a drop or smoked, but it did pump about 2 qts through the vent in the catch can in maybe 15 laps.

Oh and good god is it fast. It makes Willow Springs feel like an autocross and that isn't hyperbole. I actually noted my head sharply slamming against the seat sharply enough to momentarily disorient me, when I rolled on the power in 4th going up the hill into the Omega. Must repect the torques..

So no complete laps yesterday at WSIR. New PCV system is in. Going back to Streets of Willow tomorrow to see if it works. Fingers crossed. If it doesn't, we'll pull another all nighter to put the 4W (spare) back in. Load up Monday am and off to UTCC.
Think happy thoughts..

Creative venting solution! Sounds like you need a dry sump system that pulls vacuum in the future. Keeping my fingers crossed for you guys.

400whp + Streets of Willows =

Flailing around trying to come to adjust to the power. Still did a 1:18.17 with a solid push everywhere, missing apexes and basically not using all the available grip. Windy today. Probably a 1:15 in it once we get handling dialed in and comfortable with it on a less windy day.

PCV issue 90% resolved I think. Still blowing a tiny bit out the breather but only after 4-5 hard laps. Friday it would send 1/4 qt per lap. We will add a catch can to the vent and see if that manages it completely.

Is this with coolant routed to the AOS?

Not yet. That's mostly to burn off water vapor which is not a problem yet.

Something to consider is your fuel. I was filling up my catch can most of the day during my last outing. The next day I went all day within emptying once after moving to another batch of fuel. I surmise it was water in the fuel causing excess vapor blowby. It could have been moisture in the oil but that level never changed.

Just food for thought.

So it's still blowing more oil out the Breather than we would so we are going to put a check valve in the drain line. It's a separate line that we assembled last night so just swap in the new one with a rollover valve in it. Needs to have basically zero cracking pressure so the oil Mass draining out of the separator can open it and flow into the pan. Any positive pressure in the crankcase will close it so any oil in the line cannot be pushed back up the tube, which is what we think is happening.

We really don't like how long that assembly is and all the new failure points but it is what we could build with parts that we were able to purchase on Saturday with such short notice. If the check valve makes our PCV work 100% then we will build a new one that is much simpler.

Check valve was the ticket. Zero oil out the vent, everything running back to drain. Staggered 245/275 didn't work. Wouldn't rotate. Couldn't fit the 275's under the front fenders, so we went back to 245's all around. Raised rear a bunch and finally got it to rotate. Going to install the Small Fortune 5/8" 3pc rear sway bar and see if that gets our balance dialed.
Managed a 1:17.9 with about a 25mph wind blowing. I think we are ready.

Wow. That is nuts.

I think the fastest a time attack car has gone there during an event was FXMD NSX in 2009 at RTA, which was a 1:18.555. The fastest GTA record is a 1:19.397 by Jeff Westphal in the GST Subaru "L" in 2011. That car has progressed a ton since then and never been back but still, impressive.


Edit: NVM thought you were still at big Willow. But pretty close to SOW Unlimited AWD record by Lyfe GTR. Only 0.9 seconds off.

I did a breather in the same place on the oil pan, but hot side. At PIR (all right turns) with way less power and grip I puked a quart of oil into my engine bay. There is a cast flat spot on the blocks right above that that used to have a breather on the gtx wrc cars. That might be a better place (and it's where bbundy has his tapped)

Sounds like it worked for you on a test day though, so maybe I just had bad luck.

Or you didn't read the part about the check valve?

I read it, but my understanding was there was another drain line with a check valve, might have just been me misreading though.
