Someday we'll do LS together Jack. ( I doubt I'll be able to make the date coming in a couple weeks.) You just need to be there when I finally decide to drive all the way to Willow Springs.

Nice laps at laguna! However, we are going to tape your hands to the wheel Jack!! There is at least 1 second right there. Thunderhill is more forgiving, as your 2:01 would be more like a 1:41 at laguna. Laguna requires on the edge driving at every turn.
Love the car, its beautiful!!
Did you just go to laguna recently? I heard they repaved it, yet again.
were the birms as harsh as they are on my video from the last race of the SCCA season, last Nov? the track i thought was grippy, and not as bumpy as the Grand Am guys were saying, but they are going so much faster in the Rolex groups.

I hadn't been there in four years, so I treated 2 as a throwaway, pretty much. I'm sure I could finesse it better, and double-apexing it would probably be worth trying (although my car is heavy). I also definitely wasn't getting as much as I could out of 5, 6 or 9. My best lap time was a 1:42.35, and my data logger said I could do a 1:40.8 just with the good segments I ran in that same session -- so I still had a lot of progress to make.
I think I could be sub-1:40 with another couple of days to fine tune things and build up my comfort level. A ridealong with someone who knows the track better than me would also help.

Thanks, Mark. I was there Monday and Tuesday of last week. I understand they're about to pave it again, believe it or not.
It might be that my suspension is too compliant to notice the bumpiness. I liked the surface and I liked the berms, although I miss the old braking zone for the corkscrew and I suppose I also miss being able to see the really big black mark on the wall out of 9 where I totaled my car in 2003. They've moved the wall and covered my mark with tires.
I was instructing and giving a lot of rides, so I wasn't able to focus as much on re-learning the track as I would have liked. I was also was on Toyo RA1s that hadn't been shaved and were on their first event -- so I knew my lap times wouldn't be spectacular no matter what.
Them's my excuses, and I'm stickin' to 'em. Next time, I hope to be sub-1:40. (Although who knows what the next paving job will be like?)
I'm also gunning for a sub-2:00 lap at Thunderhill in April. Any tips?

funny, you and i have one thing in common. the dubious honor of a post corkscrew screw up! mine was 2002, and not too many race laguna more than i do, and i think about how i screwed up on turn 10 almost every lap!
I too liked the brake zone before the big change last year, but its nice having all that more room and a straighter shot to entrance of the corkscrew. the pavement was better, but they have played with the birms several times . i see they still have the extra birm to help stop the offroading corner cutting! now my evo friend has to keep the 4x4 on the track. (otherwise you loose a rim and probably the tire too!)
I think the only thing you need to do is grab that wheel at 2-10, and really work every single corner. the track is about 1 second faster for us 1:39+ guys for some reason vs the track config earlier last year. speed GT and the faster crowd seem to run 2 seconds faster now!
as far as thunderhill. there is a lot of time made up running really deep and trail braking into turn 2 . your video shows the bypass, which we never run anymore. so the only other place to make up time is turn 8, where there happens to be a lot more run off now. think road america kink, without a wall!
whats that 993 motor have as far as hp? seems like it runs really strong!
i know my brothers stock DE 911 3.2 puts down 210rwhp, i have to imagine that that your motor is better prepared and should be stronger. If you dont have near 260-280rwhp, you are still driving the wheels off it. whats the weight again?even though i race one of those front engine porsches, I still like the looks of the widened older 911 racers with fat tires. very cool!

I had a student once who had been taught a really deep line into 2 at Thunderhill where he came in basically very late and to the inside, rather than the traditional right side and earlier entrance. He'd been taught the line by a racer, and I assumed the guy had just taught him a defensive line into 2. But maybe it's worth playing with a little -- to go in a lot deeper and then rotate the car like it's less of a sweeper and more of a harder turn that leads to a sweeper.
I won't go below 2:00 without the bypass, though. I'd be shooting for a 2:01 or 2:02 with the cyclone.
In any case, thanks a lot. (And my apologies to the original poster for the thread hijacking.) It sounds like I'm doing all right, laptime-wise. But you're right: it's a track that rewards technical skill and consistency and I'm still leaving a lot of time out there.
My car is 2515 pounds with gas -- over 2700 with the driver. It's got a 964 motor, not a 993. It's never been modified or opened, although I've got B&B headers on it, which helps its stock 247 crank hp a little -- it dyno'd at 228 hp at the wheels, although I suspect that was an optimistic dyno. It sounds good because it's got a Camaro Flowmaster muffler and short gears.
And I agree: nothing looks quite as sweet as a widebody 911. I stopped at the James Dean Memorial on the drive up on Sunday, and snapped this picture at the cafe, there:

jack, you were doing great considering your 4 year absence. i was the exige behind you when you twitched sideways at T2 ;-)
the lap i waved you by i was doing 1:46 ish. with your car on a good day, you should be at 1:40 so so. i got to 143 at some point in the exige, full tread RA1, otherwise stock.

Here is a 2:01.xx in traffic using the cyclone. (like a 1:59 or so without it)
This was the free practice day SCCA held at the end of dec. thats mike Cortney in the SSF BMW. we had fun dicing around as i was out there to finally fix my big push by finally adding a real splitter and removing some cup car wing angle!
Going deep and narrow into turn 2 saves quite a bit of time.
Turn 8 is a big deal too, but you dont want to bite off too much!
I think you should run with us in ITE. Its a great crowd and you would fit right in. But then you would steal or share the honors of racing one of the only street licenced cars out there.
