Hello,

Just returned from a DE at Mid-Ohio. I've posted some in-car video at:

There was a PCA club race this weekend, and the A-Group was filled with racers doing test-and-tune for the race. I missed one of the instructor runs, so I decided to go out with the A-Group. They kind of messed up the lineup, and they grabbed me to go out in front of the pack. So I got to see most of the big dogs - whizzing by. I cut the video down to just a couple of laps. Fun, but humbling.

I encountered one odd glitch. I switched to a new set of Hoosiers just before this session. I had run Michelin PSC's before, but I think I'm converted. A couple of times as I got on full throttle, the car seemed to cough briefly. I also noticed that the little yellow light with the triangle and exclamation point flickered at the same time. I later found out that means WTF? from the PSM unit. I am pretty sure that what caused it was the rear tire slipping on the rim. Both rears moved about 1/8 turn sometime during the run. I had them rebalanced at the Hoosier truck, and one was off 3 ounces and the other 1.25. That produces some rather noticeable vibration at 150 mph.

One other thing - I bought rear control arms and toe links from Dan at Vivid Racing. They worked out great! I ran with -2.5 deg camber in the rear, and for the first time ever, I saw pretty much even tire wear and temps across the rear tires. Now, if I could only figure out how to get more than -1.8 deg in the front. Camber plates are maxed out.

Wow, that looked like a LOT of fun. I was actually invited to two track events on May 5th, unfortunately I couldn't attend either. I'm going to have to keep in touch with the local Porsche guys so I can find the next event!!!

 

There is a KYPCA event in June at Putnam Park. http://www.kypca.org/info/de.pca

 

Very cool. I ran Mid-Ohio once in a vendor track outing. We weren't running Porsches nor were we running those speeds.

 

KY region runs a very good event.

Here's a photo of my car coming out of the carousel...

 

I'd love to do the KY event in June, but I've got 3 baseball games with the kids that weekend, 2 of which I have to coach. I'll keep my eyes open, though, and make it to something this summer!

 

Central Indiana has an event in September at Putnam Park. Always a very well run affair. A friend and I usually do the classroom for them, but I'll be out of the country for this one.
