Chuckwalla Valley Raceway Lap Times?

Amigos,

I had the pleasure of taking the my 2004 986 2.7L to Chuckwalla this weekend. When I got there I found that the other drivers in my group were much more capable that I was, and were lapping in dedicated track cars with 50% more horsepower and r-compound tires. This made it pretty hard to judge whether or not I was turning respectable times for the car setup that I brought, or if I was leaving time on the table.

I did take solace in passing a 2018 Cayman S, but as you can see in video, I got myself offline, into the sandy part of the track, and promptly spun out! hahaha.

Video of Lap Here

Anywho. I managed a best lap of 2:16:59 in a base Boxster with street tires and no mods. Does anyone have any data to suggest if this is decent or not? Any insight into the best lap to expect from a stock Boxster in a street configuration?

I checked out fastestlaps.com and saw that Randy Pobst did a 2:04:53 in a 306hp Audi TT-S, which made me feel pretty good.

Thanks!

Comparing times is a bit superfluous since chances are it will be an apples and oranges comparison. Tires, tire pressures, suspension mods, engine mods, driver experience, and weather conditions, to name a few, all influence lap times and it will be nearly impossible to get a true apples to apples comparison. It's best to work on safely improving your times. That is enough of a chase in itself as there's always something that could be better. Videoing your sessions is a great way to find places to improve.

Your lines thru the corners generally look good. However, there were a few corners where you missed the apex by quite a bit. While there are very few "perfect" laps, if you're missing an apex by a car width or more, try backing up your entry brake point. That should allow you to dive to the apex. Missing an apex by a car width will cost you, so that's a way cut time.

The Cayman was late in giving you the point by (you were entering the brake zone). It's up to you to decide IF you should take the point by and can safely execute the pass. It's perfectly acceptable to wait for a better place to pass. Or if you do pass, you must carefully execute the corner, usually on a different line. That may mean going slower to make it safely thru. A lot to consider in a split second. This time it wasn't a costly learning experience. Have fun and bring all 4 corners home safely.

Thanks for the thoughtful reply. Very much appreciated. I was certainly pushing myself and blowing apexes as I learned the track and the limits.

I was just hoping that someone here would be able to provide some anecdotal information that would give me a best case target to aim for. Something like, "my buddy Sebastian Vettel (haha) ran a 2:07 last week."

I've driven Chuckie a bunch of times with PCA SDR and a 2:16 in a stock 04 base is respectable
You had a pretty good line as well


BTW, if you are into tracking, you should look at PCASDR, we do a lot of track events and 2-3 weekends a year at Chuckwalla

Also, I have 2 sets of track wheels in 17" for a Boxster I need to sell. I'm moving out of state and done want to move them
