Three hour tow from portland, two mile gravel road to track from Grass Valley- no gas or services at track, but I was excited to get the "zonk" out on the track for the first time!

ORP is still a work in progress, but from my point of view, the track is challenging and quick. The videos DO NOT give justice to the elevation changes nor the blind apexes. The track is a blast to drive but will take some time to find the really quick line around.
There are a couple of areas that I found particularly challenging - the braking zone into the barn turn, and the last uphill off camber turn with a blind apex at a K barrier onto the front straight.
Honestly, it is the most physically demanding track I've driven in a while. I feel like I was in a shifter kart! Sore and tired from being used and abused.... But in a good way.
The gearbox I have in the car is pretty good for this track. (A GA M Q V) Third gear in most areas with second only once (when I messed up) fourth and fifth on the two straights when running about 7/10's. Front sway bar set at mid stiff, shocks (koni yellows) set at two clicks (mid between full hard and full soft). I am not running a limited slip nor am I running a rear bar. The setup was very neutral and predicable. Tires were at 32 all around (cold) and headed to 36 all around after the quicker second session. Oil temp was a problem as it didn't get over 150! Trans temp was 155 with no cooler.
I only ran the first two sessions as I set off my extinguisher system (by accident!) and didn't think it prudent to push the car any harder without a fire suit and a functioning fire suppression system! Besides, it was my first "test" track day and I didn't need to do anything stupid!
If the economy cooperates, I will do more this summer at ORP. Next time, I won't forget the DV camera!
