Would be nice if you had some lap data going in the video. I've run hundreds, maybe more than a thousand of laps there. Your line looks good, You may be hitting some of the curbs a little hard. My key points and speeds are top of S's at least 125. You should not lift from apex turn 2 to bus stop. Bus Stop enter at 85-90 exit 80. Carasel. to turn six 110 before down shift. +60 turn 9. +85 turn 10. 11 4th gear at footbridge 5th gear start-finish.

I only have a 5 speed. but a 3.6 motor. best lap 2:13.5 average 2:15, 2:16

Very nice, one day I am going to get up to Watkins Glen but it would be a 16 hour drive to get there. I was going to say, check out jsceash but he already posted, he seems to know a lot about that track and is quite fast there...

I just got back from Road Atlanta in my "new" 2009 base Cayman, and during this weekend I was able to learn some of the car, and build up some trust in it, and begin to push a little harder. I got to within a second of my best Boxster laps from last year (low 1:49 in boxster, 1:50.07 Cayman), and feel like next time out I should be a little faster. To compare on the same day a friend/fellow instructor with a 981 Cayman S PDK with mods, exhaust, tune, and Toyo RR could only get a 1:40. It was hot!

Here's a comparison of my fast Cayman lap and one of my 1:49 laps in the Boxster - the Cayman has more grip in the corners (wider tires, Ohlins Road & Track) but I'm not taking advantage if it... yet... only in a couple corners was I faster in the Cayman, I need to work on that...

https://viewsync.net/watch?v=NxGCvwbGCio&t=488&v=IjC6IXl8qbA&t=13&mode=solo

Since the data comes out faster through the OBDII port on the Cayman, I was able to read more data including coolant temp and air intake temp, and still get a good update rate on rpm and throttle. Even with thrashing the car, and only 2 radiators, the coolant never got above around 215F. I think the car might be pulling timing when it gets got to help with temperature? I have the 3rd radiator kit but haven't put it on yet. A surprise was that with an outside temp of 90'ish F during this session, the air intake temp was around 20 degrees higher. I would have thought that the fast air rushing in wouldn't get a chance to heat up that much. That is an area I would like to research more.

I also had an odd thing where on some sessions my Aim SOLO DL only got TPS data from the car instead of RPM, temps, etc. Maybe the wire is getting old but if it failed I would expect to get all or nothing, and not just a single data metric from the car. Weird...

I had a great student with a Camaro SS something (track package but no super charger) - we ended up running in 1 group up from the instructed novice since we weren't able to get any decent laps in the green group. The car was really fast, but he was really fast too, in the intermediate solo group we were in, we were hanging with Corvettes and the supercharged version of his car. I took him and his wife out for a demo ride in the green group and got to play with traffic a little bit which was fun:

yeah, i'm using harry's right now and I can't get the overlays to transfer for some reason.

I should be running 2:15s or so. need to carry more speed into turn 1. Bus stop curbing is an art it seems, some guys like all of it, some like none. I do not lift from apex of turn 1 to busstop. Max speed was like 127 or thereabouts. I enter bus stop at like 80, need to work on that a bit. I was at 89 on turn 10, I did not have to shift into 5th on the front straight.

Not an excuse for my slow time, but it was in the high 80s and the track felt pretty greasy.

I'm also finding with my 5 speed that it wants a 3.5 gear as 3rd is a bit short, and 4th is a bit tall in a few spots.

thanks for posting your vid.
