Well, today put another great Spring HMSA event at Laguna Seca Raceway into the books. I attended as a spectator, not as a driver or crew, so I had lots of time to visit with friends, take pictures, and watch some great racing. This year’s featured race group was the 2.5 Trans Am class, resurrecting the epic small bore battles at Laguna Seca during the early 70’s. There were dozens of Datsun 510s, Alfa GTVs, and BMW 2002s on hand to give the fans a real thrill, and a big Congratulations goes to Mark Boen for driving his Moore Speed prepped Datsun 510 to the group win.
Lots of beautiful machinery was on display making the pits “the place to be” on this sunny Sunday afternoon.
This is what makes America great: the creativity, the ability, and the lunacy to fabricate an airplane themed race car! Kudos to Jeff Bloch for an awesome build.
The Trans-Am B-Sedan (T.A.B.S.) 2.5 Challenge – West racing series is officially up and running! The series is an extension of the T.A.B.S. Midwest series that has been successfully running for a few years. The Challenge series runs with different clubs on different tracks, and includes cars from the SCCA B-Sedan/Trans Am U-2 series, and the IMSA Trans-Am 2.5 series, that raced from the mid 1960s through the late 1970s. The Challenge rules are pretty simple and inclusive – period vintage prep, cars must weigh one pound per cc (e.g., a 1800cc car must weigh 1800 lbs), and use a 7″ wide wheel with a 205 DOT race tire. Sounds good to me, count me in. The first race of the 2013 series will be run with VARA at Willow Springs Int’l Raceway April 4-5.
It’s hard to bitch about having too many racing opportunities, but geez, do they have to all be the same weekend?!? All three of California’s vintage race organizations are competing for small bore attention the first weekend of April. VARA is running the T.A.B.S. 2.5-West Series at Willow Springs Int’l Raceway, SVRA-West is running their 2.5 Challenge at Thunderhill Raceway, and CSRG is running the VSRG 2.5 Challenge at Sonoma Raceway. Hopefully there are enough 510s, 2002s, and Alfas to go around… It’s a great time to racing a small bore racer out West, I just wish I could make them all!
The dyno day at Z Car Garage went well for the wagon, a few jetting and timing adjustments later and the new motor is running like a champ. We even discovered a second small muffler actually added a little horsepower as the motor liked the extra backpressure. The break-in oil has now been replaced with the good stuff, the head re-torqued, valves reset, and it’s time for a test day.
Sharing garage time with the wagon has been my Honda cb450 resto-mod project. I finally got the ‘Green Hornet’ out for its maiden voyage this week and while there are a few small projects left on it, its really nice having it back on the road.
Well, after 2 1/2 years of racing the wagon, it’s time for a rebuild. While I’ve been tweaking and tuning all along since build completion in 2010, there were a few tasks awaiting a full tear down. Mike at Malone Motorsports helped me with the L20b rebuild and the guys at Nissan Parts Warehouse supplied some parts, Paul at The Moore Speed Co. helped with the drivetrain mods and swap, and John at IEM Racing helped with a fresh chassis set-up and rewiring. I’m blessed that all these guys are my buddies, and that they don’t charge me double for working on my car along side me…
The fresh L20b has a little more compression and a little more cam than the motor that came out, and a new clutch with a freshened Z tranny should make rowing the gears a little nicer. A day of bumpsteering, stringing, and corner-weighting should make the handling a little sharper, and the taming of my rat’s nest wiring will make troubleshooting future issues so much easier. Next week should see a little dyno time and a test day at the track 😉
