Sonoma Trackday Video (spinout included)

[orthojoe]

I had great weekend with my buddies at Sonoma this weekend. We did a 2 day event and I took the BRZ out for the first day.

Unfortunately, I did a 360 coming out of turn 6 on the 3rd lap of the first session. My best lap of the day was the 2nd lap of the first session. Only 2:07. I got spooked after the spinout. Too much carnage that day. A totalled Cayman S and after a car to car contact with a spinning F360. Multiple damaged cars that day. :-( I should have treated the stock tires with more respect and waited for the conditions to warm up before running hard. I'm used to NT01s getting sticky after only 1-2 laps. I will return again to try to conquer Sonoma with the BRZ later this fall.

If you listen to the video, you will hear a pop and hiss as I spin. I pulled into the hot pits after the spin and the car stalled. The car wouldn't idle and would stall out. If I kept the revs up, it would run just fine but you could hear a whistling sound. It turns out a PCV line blew off. Interestingly it wasn't clamped down or anything. I reattached the line, put in a ziptie, and the car was perfect again.

Here's the video:

I'll share my video from the following day in my spyder as well. I was able to get 1:55:

Nice spin! So did you spin from going too wide on turn 6 or was it from early throttle? I'm interested to see which hose popped off.

Looks like fun to me!

What software are you using for your vids and lap timing? Been thinking about getting a similar app... Any opinions?

LOL. Thanks. You know, I'm not really sure what caused the spin to tell you the truth. I think my line was fine, and if you watch the video I was already unwinding the steering wheel and was barely on the throttle when the spin occurred. I didn't pinch myself off and I wasn't goosing the throttle. I don't think it should have happened, but it did. The was the first session in the AM, so track conditions were cold and it was only the 3rd lap so the tires were cold too. I'd love to hear any opinions on what happened. Right now I just think I was driving the car too quickly for the cold condition and wasn't talented enough to stop the spin.

Here's a pic of the PCV line that blew off. Its behind the intake manifold near the firewall on the passenger side.

I'm using the AiM solo as my datalogger, gopro cameras to grab video, and then doing the dataoverlay with trackvision software and post processing with adobe premier elements.

love your work on the video!

Your spinout reminded me of the one I had this past weekend at Sows (CW) @ Turn 10..

Wow nice! Strange spin.. you lost traction out of nowhere! What datalogging system do you use in the BRZ vid?

I had a similar spin at thunderhill. I was taking the bypass like I had been doing all day long, nothing new or different except if you look closely at the video, there was some sand that someone left for me from the last session. THat and the RS3's were not warm enough yet.

I remember that video! .. I think these stock primacy HP tires can run pretty loose particularly if track conditions are cold. I'm used to NT01s warming up after only 2 laps. Notice I spun out on the 3rd lap. I incorrectly thought the tires would be ready. Lesson learned.

Ill second that did one track day well ok maybe 1&1/2 and quickly came to the conclusion that they are better suited for the prius

Great driving orthojoe! Kinda odd spin though.

No! I will continue to resist for now! I have smmmurf and Pobst as my benchmark with these tires. These tires only show how much more I need to learn about car control still.

Thanks! Are you saying the spin occurring was odd, or that the actual spin was funny looking?

Of course it was funny looking

Beautiful video - thanks for sharing!

I think most of us in this sub forum have had the cold tires / cold track experience
