yep--my 1st thought was the s.c--but it was full.
it was engine oil and it was in the blow by valve, in the upper intake etc and actually dripping out the filter--all over the air box--coils and the maf of course.
i was meatballed off the track as they saw a little smoke--glad they did.
now i was thinking OK it has puked back through the crankcase vent tube that runs to the intake --right --but soon realized it didnt--heck that tube was dry and patent.
the only way engine oil can get into the combustion chamber is a side seal right?
i still have not figured out how this has happenedd. Clean since that time.

Intresting, did you track down were it came from yet? Did you say your putting vac to your crankcase vent?? Ive never herd of puking a 1/2 quart. Ive herd of it foaming, were is your T at on the oil fill, you might have it to high, you should have the T as low as you can get it then run your vent hose as high as you can. As for cleaning your IC out, you might have to bite the bullet and pull it apart. You might also have oil puddeld in the lower half of the blower, I wouldnt try blasting it out with meth either, spraying as much as it would take might wash out your seals and cause premature wear and tear. If it is puddled in your blower its gona be a big head ack and maybe cause more problems. To much oil is better then not enough in this case but im curios were it came from.

Denny:....it's kinda weird..but mine did it once on the track NA before the turbo
Never did figure out what it was...and it never did it again.......Wonder if something stuck up a side seal for a few minutes and it blew by enough to pressurize the crankcase....puke the oil..and then it unstuck??
I think you will have to pull the IC out to clean it up as well...you don't want to cook all that oil into sludge in the IC and blower

never did figure out where it came from--hasnt done it anymore---drove for a few sessions after i cleaned it up and cracked the dipstick(has been fully inserted ever since)
i cant get the intake air temps down even with the water meth--on track on 78F degree day engine temp 185--intake air temp 170 WITH water meth going. Still going 50 over ambient everyday driving now. Making boost OK.
Yep I have the regular crankcase vent setup and never have had this happen before
gremlins?
I do NOT want to take the s.c/ intercooler apart--i have 2 days of track at Road Atlanta this w/e!!!!! Have to work etc etc etc. What should I watch for?--i got a cleaner--rag and various wiggly medical instruments..... cant i do it that way?
intake temps on street around 115-125F without w/m.

Idea, try the rag on the end of a coat hanger and go fishing for oil through were the throttlebody mounts. Maybe you high temps migh be from the oil sump you might have going.

Trust me on this one.
Do not try for oil-wings......

well--golly gee--i ended up spring cleaning--plus found out my w/m solenoid was working only sometimes
vented the crankcase a little differently per "The Man" suggestion(Juan)
i now have one of those cute little valve cover vent filter things inserted into the oil filter cap--does look kinda cool---plugged the air intake vacuum hose that WAS going to the crankcase, vented the s.c. down the back of the engine, rechecked my solenoid and it is NOW working--- so now i am tired and I quit
Enough already gremlins--enough

thats going to be a sweet set up--suggestions?
make the air scoops taper toward the back a little, turn the coolers around so that the hoses are up front and in a cooler area--not next/close to the a/c condensor or radiator.
make sure that the air damn belly pan can still vent enough at high speed that you dont get air pressure build up--tapering the back of the scoop will help with that.
do they need to be that tall? the vacuum under the car while it is moving will pull air through them--shorter scoops will also unblock the airflow some and maybe give room for a fan?
That a great set up--kinda like it better than my own.
i have heard that the 09 thermostat is different--earlier opening etc--anyone know for sure the specs?

The scoops are only between 2 and 3 inches tall and they do taper. Not much extra weight, they dont even sag the belly pan. Id say there well worth it vs problems overheating.

I had that happen before and resulted in a bad case of detonation under heavy load. I would highly recommend switching to a metal type check valve instead. I have been running one for the last 6 months with no issues whatsoever.

understand man---one is on order--great minds think alike
`BUT--BIGGGGG track event this w/e and it doesnt have time to get here. Seems snow has updated their solenoid also and SUmmit racing has one which i will pick up on the way to road atlanta. I will also have a connector available if that doesnt work out. The car will run great without a solenoid(actually it will cool much better) and that will be OK for the track I will just have to readjust the maf settings some because it flows more. Call it insurance. Meanwhile I just needed some street ability that so far--is working.
Alabama gas was crappy.
I need to get a pic of the crankcase vent filter mounted in the oil cap---does look pretty good.
The s/c vent doesnt need suction does it?

I just replaced my OEM P2 380cc yellow fuel injectors for a new pair of 2009 P1 390cc green fuel injectors. 
As you can see (attachments) the fuel spray patter is different from the 2004-2008 injectors. They deliver a better fuel spray/atomization pattern. The same goes with the 2009 P2 brown fuel injectors which I’m currently running in my Auxiliary Port (outside left and right of the fuel rail) position. Check out the a quick log I took right after installation. The car seems to accelerate faster and whp will be determined next month on the 5th at Delirium Motorsports Dyno Day in Kissimmee, Florida.
