Great video. I think you got too excited when you were close to the Viper and about to make the pass. I think it's a common mistake in races. When we get closer to making a difficult pass (that is going to be a memorable one) we become a little impatient and push it jussst a little too much.
Great video and excellent driving. By the way, you must have had the carpeted engine cover removed as that is the only way we could here the throttle body so clear. I have mine removed also and I enjoy the sound. It saves about lb 8 in weight too  .

Great Video Ken. I too have looked down wondering what the heck was that when the fuel alarm chimes off unexpectedly.

BTW, did you have PSM on?

PSM - Porsche Stability Management
|
 |
While it can’t overcome the laws of physics, the revolutionary Porsche Stability Management (PSM) system does lend an added degree of balance and control to the Cayman’s mid-engine driving dynamics, inspiring surefooted confidence in corners and extreme situations.
A standard feature on the Cayman and Cayman S, PSM continuously monitors steering input, road speed, yaw velocity and lateral acceleration to calculate the actual direction of travel. If the car begins to steer off line, PSM instantly intervenes with precision brake inputs on individual wheels to help bring the car back onto the driver’s intended path.
If braking alone isn’t enough to correct the vehicle’s cornering line, PSM then calls on the Cayman’s engine management system, adjusting engine output as needed to help stabilize handling. PSM can also compensate in an instant for mid-corner changes in load resulting from deceleration or braking. When Sport mode is selected with the optional Sport Chrono Package, PSM’s threshold for intervention is raised, allowing for greater driver involvement. If you prefer driving without automatic PSM assistance, the system can be set to standby at any time. In this case, it will only intervene under heavy braking, where both front wheels exceed the ABS threshold.
For all of its technical ability, PSM goes virtually unnoticed in everyday driving situations, preserving the Cayman’s natural agility. |

Yes, PSM was on, never saw it kick in did you?  Thanks to the TBD/ LSD.... car was in Sport mode.

LSD - Limited Slip Differential
|
 |
A limited slip differential (LSD) is a modified or derived type of differential gear arrangement that allows for some difference in rotational velocity of the output shafts, but does not allow the difference in speed to increase beyond a preset amount. In an automobile, such limited slip differentials are sometimes used in place of a standard differential, where they convey certain dynamic advantages, at the expense of greater complexity.
The main advantage of a limited slip differential is found by considering the case of a standard (or "open") differential where one wheel has no contact with the ground at all. In such a case, the contacting wheel will remain stationary, and the non-contacting wheel will rotate freely– the torque transmitted will be equal at both wheels, but will not exceed the threshold of torque needed to move the vehicle, thus the vehicle will remain stationary. In everyday use on typical roads, such a situation is very unlikely, and so a normal differential suffices. For more demanding use however, such as driving off-road, or for high performance vehicles, such a state of affairs is undesirable, and the LSD can be employed to deal with it. By limiting the velocity difference between a pair of driven wheels, useful torque can be transmitted as long as there is some friction available on at least one of the wheels.

Yeh I guess that would help otherwise when you whip it around the corners the PSM goes off like a brides nighty.

Ken, really nice video, and I'd love to try that track some time!
I'm also a national PCA instructor, and have to agree with previous comments: gotta quite the shifty hands. Take it from a reformed hand-shifter! I paid a healthy body shop bill in June due largely to this all-too-easy bad habit. But I'm fortunate enough to have the coaching services of a very good Grand Am (ST series) pro driver, Aaron Pavolado, who beat me about the head with a stick when he saw my hands in the video prior to and during the spin that caused the damage. Yes, it was during a race, and yes it was raining, and yes I hit standing water, but it would have been catchable if I'd not been shifting my hands, I've since proven that to myself in subsequent skid control clinics.
You mentioned that "your arms aren't long enough" to hold the wheel properly. Two suggestions: a more upright seatback (assuming of course you have the adjustable wheel all the way out), and then if that doesn't work, a wheel extension...they make a variety of them. As the Cayman doesn't come with a sunroof, the more verticle seat back works for nearly everyone, and is clearly the cheaper and easier solution.
But you HAVE to fix this. Trust me, putting a salvage title '93 325is track car back together is a heck of a lot cheaper than a CS! Shifty hand WILL bite come around and bite you in the butt sooner or later.
(BTW, gutta love the radar detector on the windscreen! LOL! How'd that get past tech???!!!)

Hey just to put the hands issue to rest last time out I shifted hands a lot less, a couple of places still require movement because of the greater than 90 degree turn in a short amount of space, but in other areas no problem just keeping them still, thanks for the concern but maybe I should take that video down if people are still concentrating on my hands and not what the car can do.
Oh and that was a G meter, not radar detector.

Dont take it down. It's a good video. As you said it shows what the Cayman can do.
And the shifty hands discussion is helpful to the less experienced drivers.
Im out to the track next week. Running bone stock with only Pagids as the sole mod.
I dont have a camera mount (and if I can get one rigged up I will post a video). I have a mount for my old (now departed e36) that fit on the headrest rails, but dont think that works on the Cayman.

Sorry if I was beating a dead horse, Ken! Please don't take down the video, it's a very good one, and you did great! 
You'll get that Viper next time, I'm sure! Besides, that poor guy has to listen to a motor that sounds like a dumptruck in need of a valve job, while you've got the S mill's symphony playing all day long....

Sorry. Don't know sh&# about tracking my car...yet. But what track was that?

I just had the chance to watch the video and read some of the comments so I'll spare anything that was already said.
I would invite any of you other instructors to come up to Montreal and join in on one of our Instructor days, I think you will be VERY impressed with the speed and quality of my fellow instructors.
hand position, proper heel and toe, head and eye position, proper seat and steering wheel set up are all basics that we require for a student to go from white to blue. Much more is expected of our instructors.
We even have a race (red run only) in which you are NOT allowed to brake, at all. Thsi is a test of control and planning ahead...and beliwve me it's tough once you have 30 guys all going for it....
Anyway, great video. Ken, you have some extra time in there for sure.
Here is a video of one our intructors in his GT3 (997) at calabogie:
