Dear Zcarblog readers, it’s been a busy year and we are catching up on blog posts, so please enjoy our belated race report from November 2021.

WE LOVE RACING! On November 11-14 we attended the Velocity Invitational at Weathertech Raceway Laguna Seca. Z Car Garage had a blast racing and supporting several client’s IMSA GTU Z cars running in Group 7A (1966-1977 IMSA GT). This vintage racing event was just as fun for spectators with a friendly, immersive vibe. Enjoy our report from the weekend with photos and in-car video of the action.

Z Car Garage IMSA Race Car Support!

 

If you missed our earlier post, we prepared and supported three IMSA race cars for the Velocity Invitational (VI). Here’s a quick review:

#49 IMSA Joel Anderson GTU Z

#47 Brad Frisselle IMSA GTU Z

We supported our client Randy Jaffe who recently acquired the Transcendental Racing Datsun 240Z. This famous 1976 IMSA-GTU Championship-winning 240z will be driven by ex-driver Brad Frisselle’s son, Brian Frisselle. Randy recently had the Z re-painted by William with correct graphics and hand-applied livery by the Real Ralph.

 
 

#93 Different Drummer Racing Datsun 260Z

Race car driver, restorer and Datsun Historian Glenn Chiou raced his  Ex-Greg Sorrentino IMSA 260Z. Glenn built and prepared this race car by himself, ZCG simply dyno-tuned it prior to race week.

 
 

Ready for some L-series music from these historic race cars on the dyno? Check out the video below and turn those speakers up!

 

We also prepared our client Kelvin Tse’s Porsche 911 RSR, because if it’s not the Z-car, it’s the P-car!

 

Epic Racing With Group 7

Group 7’s IMSA GT and FIA race cars (1966 and 1977) was dominated by big-power Porsche 911 RSRs with a few BMS CSLs and 4 S30 Datsuns. Speaking of powerful Porsche’s, the organizers did not allow turbocharged cars to run so we thought an NA motor race would make things interesting. Read more about Group 7 here with driver Jeff Francis in Larry Oka’s 1970 Ex-Glemik IMSA Datsun 240Z (#54):

 

Friday’s qualifying race was eventful. Rob and Brian Frisselle were doing well and putting down some great lap times. Unfortunately, a Porsche oiled down the track between turns 4 and 5 and both Z cars skidded off the track. They recovered under their own power but the Frisselle Z sustained minor body damage from hitting the tire barrier. Good news: Glenn, Jeff and John Murray avoided the mess and Rob Fuller qualified on Pole Position!

Racing in to the Night

 

Saturday’s Group 7 would start at dusk, a rare exhibition for both drivers and spectators. I zipped up to my favorite vantage point at Turn 6 to catch the sunset. Auxillary lights were placed at each apex and few cars had headlights of their own to navigate the evening’s race. It was magical to watch. Here is Rob Fuller re-capping his sessions from the #49 Joel Anderson IMSA GTU 240Z:

 

“We had a great first session, made some adjustments to the cars and clicked-off good times. The qualifier was pretty scary as I lost control from a Porsche’s oil spill but I made it out ok. Brian Frisselle is an ex-IMSA professional driver and he safely negotiated the oil slick, avoiding a potentially severe impact with the sitting Porsche and softly hitting the tire barrier. I was surprised to make Pole-Position. Saturday’s evening race was intense. Though I started on Pole, by Turn 2 the Porsche gapped me 3-4 car lengths…

…We were racing our Datsuns with skilled drivers like Ned Bacon, Alan Terpins, and Martin Lauber in their multi-million $ Porsches. I was able to hold on to 2nd place, trying hard to reel Ned in but caution struck again, another Porsche had oiled down the track between Turn 5-6. Now its really dark and I’m trying to stay with Ned then I see these lights coming up hard on me and I know it’s Terpins. Tried to defend but he got around me. Honored to be amongst these guys who never let up. We finished the race in 3rd place.”

Enjoy this video we made highlighting the Group 7 races with in-car, Turn 6 and Goodwood livestream footage mixed in. Volume up!

You can see full, in-car footage from Rob in  the#49 Joel Anderson IMSA 240Z over on his YouTube Channel, check out the Qualifying and Saturday Evening sessions. Here is Rob recapping the Sunday race from Group 7:

“Final race was midday with plenty of sunshine. Frisselle started 4th. Three lead Porsches took off,  while Brian and I battled for P4. He then got around me and we both enjoyed the magic of driving our IMSA cars. Drivers around me were in expensive machines giving it 100%. Really happy to see 4 Datsuns in top 10 places. Honorable mention to John Murray (narrow body 260Z), Glenn Chiou did a really good job (Greg Sorrentino IMSA 260Z) and Jeff Francis (Ex-Glenn Klemik IMSA Z).

Velovity Invitational Datsun 240 Z
 

Joel Would Be Proud

 
 

You might recall the story behind this special, 1972 IMSA GTU 240z as it was owned, built and raced in the 70’s by none other than Joel Anderson.  ZCG restored #49 back to its former glory and it debuted at RMMR 2014. John Morton would drive #49 at RMMR 2015. Rob Fuller would drive #49 for the first time at the RMMR 2018. Joel was present at all of those events but sadly passed away March 2021 and we miss him dearly.

“This was unbelievable…driving the Z without Joel around was so emotional. Thinking about the fact that all of the vintage race support and seat time we have is all because we met Joel. He taught us how to be racers. His memory was shared by us all at the race.”

 

Privateer Spirit

Our friend and Datsun Historian Glenn Chiou raced his Ex-Greg Sorrentino IMSA 260Z. It’s worth noting that not unlike privateers of the period, Glenn builds his Z cars, maintains and manages his racing efforts himself. Not an easy task so we applaud his work ethic.

 

A Fan-Friendly Race Event

Velocity Invitational Historic Racing Laguna Seca

Photo by Kevin Ehrlich

Formerly known as the Sonoma Speed Festival (2019), the Velocity Invitational re-imagined the vintage race experience with a Goodwood-inspired vibe. One of the best experiences for spectators is the paddock and organizers made access to drivers and their machines seamless. Fans could get up close and personal with race cars without the typical ropes or 45-foot RVs in the way. It was a dream come true for me to share vintage racing with my family, they loved it!

 

The hot pit area where all run groups stage before heading out to the track is an amazing place to be. Typically, access is only granted to pit crews and media. At the Velocity Invitational however, organizers staged a “false grid” where any spectator could walk amongst the race cars. Our family loved the artificial turf and hay bale seating lining the grid:

Velocity Invitational Historic Racing Laguna Seca
 

Though the fresh format was immediately enjoyable for spectators, it did come as a surprise to drivers and race teams. Rob’s initial reaction was met with eventual praise:

“Upon arrival to ‘Seca we knew this was going to be a different kind of event. All race cars were displayed together under white tents in the paddock for a Goodwood-like experience. It allowed spectators to see all cars within each race group but it was challenging for the team as our tools and support vehicles are usually near us. Initially we were intimidated but got the hang of it with just our essentials.  The layout encouraged interaction and it was super fun to meet other racers, new folks and see old friends. Kudos to the organizers for doing something new and absolutely knocking it out of the park!”

Enjoy this video we made showcasing the sights and sounds of the Velocity Invitational. Rob Fuller gets interviewed by the Goodwood Livestream just before the evening race, and I included the lineup from my favorite vintage race group (other than IMSA), the Trans Am cars!

Paddock Finds

At each corner there was something special in the paddock to see like exotics, Muscle Cars, personal sports cars and even Ragtime racers. The paddock never disappoints. Here’s a few of my favorites, more in the gallery! Where else can you see a brace of McLaren Speedtails, Lamborghini Mirua, Mercedes Benz 300 SLR and Lotus Cortina in one place!

 

Exotics abound with Bugatti and McLaren hypercars:

 

Really excited to spot this Datsun 240Z in the car corral…it is Z Car Garage client Matt K. Full report soon on this pretty Z car that features our Z Car Garage Big-Brakes (for small wheels) and Z Car Garage CV Axles!

The Transcendental Racing Datsun 240Z

The iconic, 1976 IMSA GTU Championship-winning Transcendental Racing Z is at Z Car Garage! This early 1970 production 240Z has an exciting history battling against factory-backed teams with names like Jack Scoville, Brad Frisselle and John Morton behind the wheel.

 

The chassis was also highly-developed by a team of All-Stars including Joe Cavaglieri (Crew Chief), John Knepp (engine), Trevor Harris, Mac Tilton (suspension) and Yoshi Suzuka (chassis, roll cage and body). Current owner Randy Jaffe has commissioned Z Car Garage to bring this Z back to period livery, refresh the chassis and drivetrain components, and re-assemble the interior before traveling to its new home in Atlanta.

 

The Z came with many spares, period photos and even original molds for the bodywork!

 

Getting the livery sorted has begun, with a proper “Frisselle” windshield banner (left) based on period photographs (right)

 

Here is a short video of the Z as it arrived to the shop early this week. Dyno testing with video coming soon!

 

Always Meet Your Heroes

 

The “Frisselle” car captivated us for many years. We watched it race locally and and eventually shared track time with previous owner David Martin (RIP) at major historic events. (Below, Left) David Martin and Rob Fuller (#49 Joel Anderson car) in the Corkscrew and (Right) Rob with David and Brad Frisselle at the RMMR 2018.

 

You can imagine how excited we are to have this iconic race car at Z Car Garage. Big thanks to Randy for always believing in us. More photos from my brief visit:

 

 

Enjoy these videos we’ve captured over the years racing with David Martin piloting the Transcendental Racing 240z:

 

In a moment of sheer happiness, Rob Fuller can be seen driving the #47 Brad Frisselle Z through the paddock back in 2015!

 

A David Vs. Goliath History

Ever wonder about the history behind this famous 1976 IMSA-GTU Championship-winning 240z? Check out www.my240z.com. Our friend Glenn Chiou created this website to document the racing provenance for previous owner David Martin (RIP):

 

Glenn’s impressive knowledge of historic Nissan/Datsun racing is bolstered by hundreds of scanned photos, some never seen before along with stories from ex-drivers Brad Frisselle, Jack Scoville and John Morton. We are even given new insight on the R&D effort that went into the Frisselle car making it by far, “the best race engineered 240z in its period”.

LONG LIVE THE Z!




TUNING: Glenn’s 1974 IMSA GTU Datsun 260Z

Filed under: 240z,Automotive History,Performance,Racing
by Alvin G @ 5:10 pm on July 21, 2021

 

Race car driver, restorer and Datsun Historian Glenn Chiou visited Z Car Garage today for dyno tuning on his IMSA GTU 260z race car! You might remember our previous blog post highlighting the ZCG CV Axles Glenn installed himself:

   
 

Glenn is preparing for the upcoming Rolex Monterey Motorsports Reunion at Laguna Seca and we specialize in dyno tuning vintage race cars for the event. Listen to that triple-Mikuni fed L-Series roar on the dyno…Glenn is dialed-in and ready to race!

 

 

The Different Drummer Z

 

Glenn Chiou is our client, fellow racer and friend. He was one of the first to run our Z Car Garage Big-Brakes on his RHD 240Z and actively vintage races both 510 and Z cars. You may have seen Glenn’s FAR Performance 240Z in VIPS Restaurant livery as raced in the 70’s by Loren St. Lawrence. Glenn restored this race car himself and it is now going back to Bay Area Datsun Dealers livery as raced by FAR Performance privateer Walt Maas. Glenn’s got a passion for re-telling the stories of legendary privateer Z car racers and his current restoration project is the Different Drummer Racing Z raced by Greg Sorrentino. This is a really cool race car with great history and build details behind it.

 

Chassis # RLS30-000024 is a July 1973 pre-production Datsun 260Z chassis that was sold by the factory for one dollar in 1975 to Different Drummer Racing, owned by Greg Sorrentino of Troy, Michigan. It was one of the very first Datsun 260Z chassis and was built by the legendary American fabricator, Ron Fournier. This Z car has been consistently raced for the last 40+ years in IMSA GTU, SCCA Trans-Am, and C-Production/GT-2 classes. You can see more history and details of the build HERE.

 

Thanks for your support Glenn! We we will be rooting for you at the Monterey event!

 

 

 

 





 

We love to see our parts installed and used on client’s cars. Race car driver, restorer and Datsun Historian Glenn Chiou is running our ZCG CV Axles in this IMSA GTU 260z race car!

 

Glenn is preparing for the upcoming Rolex Monterey Motorsports Reunion event at Laguna Seca. A half shaft failure is not something he wanted to worry about while racing so he replaced them with ZCG CV Axles. Glenn installed set #367 himself with ease:

In 1975, the Datsun Competition Department agreed to support Greg Sorrentino’s IMSA GTU racing efforts by providing him a pre-production Datsun 260Z. Once in Sorrentino’s hands, it was left to his all-star lineup of builders to help him build a frighteningly fast IMSA GTU car:

  • Chassis preparation was to the skilled hands of legendary metal fabricator, Ron Fournier
  • Suspension duties were left to Mac Tilton
  • John Knepp of Electramotive Engineering built the motors for Different Drummer Racing

 

 

The DDR Z in action at Portland International Raceway in 1979:

 

You can read more about the official history on this Z as documented by Glenn here:

1974 IMSA GTU 260Z – Official History

 

 

As usual, Glenn’s painstaking efforts and diligence result in a faithful restoration…where parts are not available he has gone to extraordinary lengths to re-create pieces from historical photos…all from his garage at home.

 

Thanks for your support Glenn! We we will be rooting for you at the Monterey event!

 

Z Car Garage CV Axles

Over 130 sets of our ZCG CV Axles are installed in client’s cars all over the world. For more information please visit our detailed post our HERE. Below are just a few examples of race cars running out CV Axles:
