This will be my first go on Shenandoah...I printed out a copy of the map so I can keep my head down at my desk and look busy while studying the track
Here's some more track study--a youtube video of one of the last time's I ran at Shenandoah: http://www.youtube.com/watch?v=ZktmhDC_75Y

My best lap around Shenandoah occurred during the 2009 SCCA time trials, a 1:40.5.
People tend to use corner names on the Shenandoah Circuit. Turns 3,4 and 5 are called "the Hook." As you can see in the video, I like to enter the 3,4,5 loop near Turn 3's inside curb. The outside is bumpy so the normal wide entry isn't needed. Staying inside also shortens the track by about 20 feet too. There's lots of positive camber in the corner and it's uphill so I carry extra speed and trail brake very heavily.
I end up in the middle of the track between Turn 3 and 4. I like to run my inside tires over the black patch at the apex of Turn 4 which will put me about 10 feet from the apex curb. This leads to the car being near the center of the track as I crest the hill (be ready for a little over steer correction) and kiss the apex curb for Turn 5 ( late apex--this is the ultimate goal of Turn 3 and 4), smoothly go to full throttle and in one smooth motion of the steering wheel transition from the left loop to the right turn to hit the Turn 6 apex curb. Don't take too much curb here cause it can upset the car and you can end up in the outside wall. The sooner you can get to full throttle after Turn 5 the better. You can accelerate quickly going downhill in Turn 5 and you gain a lot of grip at the bottom of the hill (the gravity cavity). I typically make up a lot of ground on other cars in this turn complex.
Another area on the track where I usually make up some time is from the exit of the Karussel through the Corkscrew.

So. Whats everyones experience with burning oil on track? More specifically ap1s. I understand the officials are not afraid to blackflag you if youre spreading blue smoke around. I just switched from a hfc to tp since the hfc was rattling and now its obvious its burning. I used 2 qts through my last 4k mile oil change, which yes isn't that bad, but its obviously directly related to my right foot. If i'm sitting at a stop and rev the car out I get a nice blue plume of smoke, otherwise under normal driving conditions nada. I've got a catch can on the way and just picked up a new pcv valve and grommet from honda. Any suggestions or insight are greatly appreciated guys.
