Found out the hard way that you can not run a 20 minute road course session with a supercharger and no catch can system...I have A&A with 3.8 pulley making 7.8psi on a z51dry sump and after ten minutes its blowing oil from every tube and misting it out the hood onto the windshield from the blow off valvewhen I let off the throttle from full pulls up to 130mph. This is driving the h*** out of it though on a 2 mile course with 11 turns and 130MPH straights. I had to pit after 3 laps and clean the oil off the motor all day.
Now for the important question-elite stage three kit for z51 is what I'm leaning towards.. Pros and CONS?? Other suggestions?

Sounds like you have an overfilled oil tank. I've ran six 20 minute sessions with my procharger kit without a catch can and zero problems. When I pulled my intake pipe to put on a breather this weekend there was no sign of oil at all.

that's odd I was just barely between the two marks on the bottom side.. last oil change it took 10 qts amsoil exactly to get it there. To check oil I run for a few minutes then shut off for a minute then check. How much boost are you running I was egging over 8lbs out of the corners sometimes. this is my first dry sump engine though.
Also how do you drive during your sessions. Mine pretty much lives on the redline the whole time using 4,3,2, downshifts from 130+ down to 35mph in the tight corners and 4,3 downshifts and steady 6k rmp through most fast corners. Personally I hope I am just overfilled. whats the best way to check the dry sumps.
on a good note the race school instructor drove it for two laps and fell in love with the Z51 set up with mag ride, rev match, elsd rear end and supercharger. He turned the fasted time of the day in my car. besting several exotics and a zr1 with another instructor driving it. And yes I ran race tires....

Fill to 1/4 up the hashes on dip stick and check every now and then, you'll be fine. That is less than 9.5 qt for me. 10 is definitely too much. But yeah, take an engine bay picture and zoom in on drivers side throttle body. Driving ***** to the wall. But you don't need to hold at 6K on turns, just shift.

standard a&A routing.. Runs the .625" hose from the drivers valve cover into the intake and the small line behind the throttle body is split and run to the BOV. THe passenger side hose is plugged on the A&A set up

Bruno,
The course I ran was way more engine strenuous. Lots of high speed pulls down to 35 and back. You do drive it hard like myself but I also had a pro racer in the passenger seat making sure the car stayed wound out to the limit. he believed in downshifts in lie of full braking from high speed which I think over worked the engine spinning so hard all the time..I have some videos but I haven't got them posted yet. Ok watched your video chasing the GTR (godzilla).. good job those thing are beasts to catch on the track.. There was a 2015 modified one with 800hp on slicks on the track that no one could touch. It was ungodly fast. outran the full blown race cars that were there.
well heck how may quarts does this thing hold. I heard from 9.25 to 10.5.. manual said 9.8.. I did 10 exactly

No but the ABS bracket is relocated and if the installer didn't tighten the lines or the lines are not seated perfectly under very high braking pressure it will come out.
I had one brake line on mine that wasn't 100% seated and under normal driving I have no issues at all but after braking hard for about 10 mins on the track it did leak some. My ecs kit has the blow off right near the abs brake lines so if yours is like that I can see why you thought maybe it's oil from blow off.
It could be oil but check into this too.

never even though about that. It was relocated and in a bind for sure. and the blow off valve is inches away from it. I didn't look super close at the track as so much was going on. Just wiped it off and kept going. today will be the first good look. pulling the tubes should tell the tale. This is why this forum is so good for owners. stuff gets looked at form different angles..

Not true. A z51 car should never have more than 9.5 quarts of oil or it will end up everywhere. The OPs car sounds like it is overfilled.

I'd suggest checking the blower head unit oil level. I tracked mine and thought i was blowing engine oil. Turns out the vented brass relief valve on top of the blower was actually the source of the oil. Sustained high rpm's around a long corners can get the head unit to blow some oil. I had an A8 and wasn't using the flappy paddles. Of course the software didn't want to upshift in the middle of a turn so it held the gear longer than i would have liked.
I see in your first post you said oil was coming from everywhere, so maybe your scenario is different; but when it happened to me it misted all over the engine and it was hard to figure out exactly where it came from

This is also a true statement. I know 1st hand this can happen.
