Congrats John! You and Mark put on a clinic this week in T2.
Unfortunately that probably means my "new" T2 996 will now need more weight next year .. oh well.
Thanks, really appreciate it. I really had to work for this one bc Mark was ready to capitalize on any mistake, but fortunately, I didn’t make any big ones. Sonoma is a great track and where I got my SCCA license back when the Russell school was still going. Fun to come back and go flag to flag.
Regarding the weight, this was the ideal track for Porsche’s when compared to the other cars, where as VIR will be a much different story next year. Oh well, that’s club racing. Happy to be flying the Porsche flag at the end of the day!
I'm so happy to put my 5th Runoffs in a row is behind me. It was the most painful worst 2 races I have ever had period. I had more fun at Indy Runoffs chasing cars then having my motor blow up. At Sonoma My car was unusually slow and lack grip all week. Both T1 and T2 were at the same time of day and both days ambient temp were near the same. I started on new tires in both races and exactly 30 miles into the race I would get this massive rubber pick-up in T5 and T9 and I was on the standard line and my car would feel like I was doing 4 wheel drifts pitching all over the place. It was so undriveable in T1 I quit the racing thinking there must be something wrong, a broken swaybar link or something. The car was fine. In T2 I finished the race but I could have lapped faster in my diesel pickup truck! I had to tiptoe though 10 to stay off that wall and brake super early for T11. Aggressively turning out of T11 & T7 were my tire cleaning turns. It was painful! WFT! I have never experienced anything like that.

really sorry to hear that .... and also sorry i didnt get a chance to say hello. i was up the hill in the upper garages and only got stuck in tech one long time.
That is really odd.. our cars are similar in many ways, and i know, even when its a complete mess, i can put on good tires and at least have fun. can you give me a link of your video, or send me a drop box link to see it? maybe there is something i can see. too much pressure? i know you have a lot of weight, but ive taking folks for rides in my car many times and only cost me a second or two.
do you change the weight between T1 and T2? I forgot , you have the C4 Zo6 405hp model, no?
Coming from the Midwest and having raced against Andrew A a number of times, I was very impressed by Kip in the GT2 race. The same with Olson in the T1 race. Those NSX’s were quick.
I’m out here racing in T2 in a 2003 Porsche CS. Qualified on pole by 0.2 seconds. Should be a fun race.
Congrats on your win! I don't know much about T2 - it looks like your car is a 3.6L C2 996 non GT3? Does the car get modifications like a dog bog, etc or is it more stock? Curious what a car like yours would weigh as well.
Cheers
Mark

looked like a fast package, but didnt the 2005 911 (997v1) come with the 3.8 liter , 355hp engine ? if not, what do the T2 911s make as far as rear wheel hp when you build to the limits of the spec. maybe, do they make their flywheel ratings, but at the wheels? or more?
thanks
I think my car dyno’d around 290 whp on a Mustang dyno when it was originally built (car has been racing in the Fall-Line camp since 2011 or so).
Impressive times for 290rwhp and 3000lbs .... How did Boden's car stack up, after all, he has a 997-2 and the c5 and c6 vets? (still hard to believe they can class them in T2.. but i guess weight equalizes)
