Uhhh.... sorry to say this but PCA SDR was the host so I assume that they cancelled the Club races at Buttonwillow (they kept the TT/DE).
The SDR BW event is this weekend Nov 2/3, not last weekend. The email I got early last week said the Club Race was canceled due to low club racer turnout
????
And yes, the TT was still on and a DE was added to fill the CR sessions

Here is video from the start of last Saturday's PCA race at Sonoma Raceway. Its too bad that we didn't get to race on Sunday as I would have been faster and more aggressive in getting past traffic. Nonetheless, a fun race at a great racetrack! Full screen in HD with sound provides the best viewing experience.

Hey Tom! I'm glad to see the car is sorted and back on the track. It looks like you had a good day.
I've been radio silent lately, but reading every word and watching every video. Keep after it!

Glad you enjoyed Sonoma. We just got back from two days there this last weekend. 1:55 in a SPB is a very good time. My best there in my Boxster as a 1:54. Wasn't quite that quick this weekend - grip was somewhat limited at times. Car had issues Sunday so only got one session in. It's by far my favorite track of the 4 I've been on. Laguna, Thunderhill, and Buttonwillow are the others.
Same race, different video... Made a good start, almost got hit in turn 7 on lap 1. There was interesting action in my rear view mirror on lap 6 in turn 7.... Anyway, finished P5.
Good to see you out there, Tom! Similarly disappointed that Sunday was canceled. In qualifying and race on Saturday I was chasing tire pressures downward -- they got way, way too high in both sessions. Boy did I get that wrong. And in the race I heard & felt a wheel bearing going bad. Very loud vibration in right turns. To get a head start on the fix, I removed the wheel carrier after the race before going home, and then on Sunday morning brought my spare wheel carrier containing a fresh bearing... to find the day canceled. This meant I had to complete the repair before I could load the car on the trailer and go home -- d'oh!

Nice video. Off behind you and back on just ahead of Tom. Looks like if he braked a fraction of a second later you would at least have had some of his paint on your car.

Great video! Glad that weren't caught up in the mess on Lap 6/Turn 7.
Sorry to hear about the wheel bearing and the subsequent Sunday morning repair. I was able to get my stuff packed up pretty quickly but then had the 6-hr drive home.

Since the PCA race at Buttonwillow last weekend was cancelled, I went to Buttonwillow yesterday and spent the day testing an SCCA SRF (Spec Racer Ford). This was my second time in this car.
The SRF is a purpose-built tube frame race car that only weighs 1,640 lbs with the driver. That is 1,000 lbs less than a Spec Boxster! Its amazing how much "stuff" a street car has that a pure race car doesn't need. In terms of lap times, the SRF is definitely faster than a SPB/BSR and most of that advantage is in the cornering capability since it has fairly similar acceleration and top speeds.
My goals for the day were to get used to driving at the limit of those Hoosier race slicks and show competitive speed against the other 4 SRF's who were also testing (including the 2019 SRF Regional (SoCal) Champion, Alex Bermudez).
The #15 car that I drove was used by five time SRF National Champion Mike Miserendino to win his 5th National Championship in 2017. No pressure.
It was an open test day so you could go out whenever you liked and stay out for as long as you wanted (no sessions), so I got almost 4 yours of track time! I was absolutely exhausted at the end of the day. That is probably the most that I have ever driven on a track in a single day.
I spent the morning learning the car - steering inputs, brake modulation, gear selection, how early to go to throttle, what it felt like to slide the car, how to recover the car from a slide, etc, and slowly building speed.
By the afternoon, I was close to being as fast as a couple of SRF regulars and Bermudez slowed a bit, so we did two 45 min sessions racing around and passing each other. It was an absolute blast!
Not a bad way to spend a Friday.

What's an SRF worth? Any exotica in the drivetrain?
Pricing is very similar to Spec Boxster's: Brand new build runs ~$55K. A nice ready-to-race car is ~$35K. A car that needs some updates or a bit of refreshing is typically in the high $20K's.
The engine is a Ford Sigma 1.6L, fuel-injected, DOHC 16-valve, inline 4-cylinder (derived from Ford Fiesta). They are built by Ford Performance and dynamometer tested for parity. It only puts out 135hp but remember, the car is 1,000 lbs lighter than a Spec Boxster. Engines last 3+ seasons, rebuilds are $2,500.
ECU is a Performance Electronics unit running a custom race tune. ECU is sealed.
Transmission is a Ford 5-speed manual.
Inboard Penske adjustable racing shocks.
The Hoosier slicks are about the same price as a set of Spec Boxster Toyo RR's but have a lot more grip and have a bit more life in them.
The suspension is pure race car with rocker-arm-actuated springs and shocks and adjustable front and rear swaybars. If you look closely at the second photo with the rear bodywork removed, you can see the inboard shocks/springs behind the muffler. This design puts the Boxster MacPherson strut suspension to shame.
There are three areas where an SRF really outshines a Spec Boxster - light weight, cornering grip, and all of the major components (engine, trans, ECU, shocks, body panels, suspension, etc) are sealed and/or numbered by the SCCA to eliminate cheating.
The downsides are that the car is bit wonky looking, its not a Porsche (for those who are brand-minded), and the cars can feel very old school (no power steering, no power brakes, no traction control, no stability control, etc).

I put the cost of tires, engine, fuel, brake pads, and gearbox at $351 per hour for Spec Boxster, and $263 per hour for SRF3. So about 25% less to run SRF3.

Built in the US by Elan, which builds professional-level formula and prototype cars.
Advantages:
Top-notch design and construction.
Toyo RR tires, which you're familiar with.
Some downforce.
A very safe, enclosed car.
Operational costs are very low at $194 per hour: long-lasting reliable engine, uses pump gas, 20 HC tires.
They have their own class with NASA.
Disadvantages:
Purchase cost: $73,000 used.
About the same speed as Formula F.
Heavy for a purpose-built car (1725 lbs with driver).
Not competitive in any other organization.
Relatively few built, so the fields aren't very big.
I think the reason more haven't been bought is that the crowd that has the money for an $86,000 car (new), expect to go a lot faster. For that kind of money, you can buy an SCCA P1 car and go REALLY fast. Too fast for me personally (I've watched their videos, and it's scary!)--I'd be happy with FF or NP01 speed. I just don't have the $86,000!
I'd be curious what an NP01 costs to rent, given that the operational costs are so low.

And of course, if you have an incident, you'll spend a LOT more to fix the Boxster (as you know!).
Lap times are about 4 seconds per lap faster in SRF3 for laps around 2:00.
On the other hand, you can't drive the SRF3 to the track!
Greg
Great info, thanks Greg.
I have been eyeing Formula First or Formula 600 as a nice track playtoy. I not planning on heavy SCCA or ??? Running, just something for fun 6 or 7 times a year with PCA

I've seen quite a few different makes of cars run in PCA "Driving Education" events, but I've never seen a purpose-built car (formula or sports racer/prototype). Check with them, but I don't think they would allow such a low, light-weight car on track with the 3000# street cars for safety reasons. Also very different performance: the street cars would hold you up in the corners, then blow by you on the straights.
Maybe you could run an FST or F600 with NASA. Although even their unlimited class for purpose-built cars is all covered-wheel, as far as I've seen.
A place that's a little lower-stress place to race a formula car would be with the vintage organizations. There's been quite a resurgence in vintage Formula Ford lately.
There are lots of fun purpose-built track toys around with covered wheels that you could probably run with PCA, NASA, etc. Radical, Ariel Atom, Diaso, Exocet, etc. You might look on racingjunk.com, race-cars.com, or bringatrailer.com
I finally got around to reading the Sept issue of PCA Club Racing magazine and was listed as a Hard Charger in the Laguna Seca race back in July where i picked up 6 spots in Race #1...
