On-Board With The 1991 Mazda RX-7 IMSA GTO

SEMA2011-30a_MazdaRX7_FC_IMSA-GTO-1 via JapaneseNostalgicCar.comThis is on-board footage from the 1991 Mazda RX-7 IMSA GTO race car as it laps Laguna Seca during this year’s Rolex Monterey Motorsports Reunion. Mazda won the 1991 season with this car. The GTO class of IMSA racing was for engines above 3 liters in tube frame cars that had production car silhouettes. Motivation for this car comes from a 26b 4-rotor engine that makes 600 hp at 8500 rpm and 390 ft-lbs of torque at 7000 rpm putting power down through a Hewland 5-speed transmission. You can see two of the three other 4-rotor cars that Mazda had at the event racing on track with this RX-7.

5-Time Hot Rod Drag Week Champion Larry Larson

Brian Lohnes of Hot Rod Magazine and BANGshift.com takes us for a tour through the shop of 5-time Hot Rod Drag Week champion Larry Larson. Drag Week is a brilliant concept that tours four different tracks over 1200 miles in five days. The winner has the fastest average time over the entire event. It’s amazing that Larry has won five times in a row in his 2500 horsepower Chevy Nova II, but his success is even more endearing because of his philosophy towards Drag Week. He races in a steel bodied car without towing a trailer full of spare parts because he believes that to be the original spirit of the competition. That’s how weekend warriors approach drag racing so that’s how he’s going to do it, too. Larry didn’t end up winning a sixth title this year, but he was beat by a tube chassis, fiberglass body car that was purpose built for Drag Week. He’s still a champion in my book.

3D Printing a 1927 Miller 91 Race Car

The CIDEA company released this fascinating video documenting the build of a quarter scale model of a 1927 Miller 91 Race Car. They showcase the four currently used methods of 3D printing plastic parts from CAD models. There’s definitely a lot more out there than just a desktop MakerBot (they are awesome, too). This is what the future of manufacturing and innovation is going to look like. It’s going to be awesome for people who like to make things.

Keiichi Tsuchiya’s Touge Monster AE86 2013 Test and Tune

Hot Version just released this video of a test and tune session of Keiichi Tsuchiya’s personal AE86 which is used as the 200 horsepower class Touge Monster on Hot Version’s Touge Challenge series. The car used to be tuned exclusively by Sakurai-san of Toyota Racing Development who unfortunately passed away recently. Now Tec-Arts has taken over working on the car. They have plenty of experience from regularly campaigning a successful car in the revived AE86 N2 racing series. Tsuchiya-san wanted more displacement so they built him a 20v 7AG using a 7AG crank, custom rods and AE101 silvertop pistons. They also sourced some custom camshafts after discovering Sakurai-san had been making power on the stock cams. The first three minutes of this video is from the Tec-Arts shop during the tear-down:


Between S-Tires and added engine power, Tsuchiya-san was able to set an outright sector time record on the Gunsai Touge beating out cars like the Amuse S2000 and the RE Amemiya FD RX-7. It’s about time I got my AE86 back on the road.

Building the Nissan ZEOD RC – Chapter 1

Nissan is documenting the construction of the Zero Emissions On-Demand Race Car (ZEOD RC) that’s scheduled to occupy the Garage 56 Technical Exhibition spot for the 2014 24-Hours of Le Mans. The last time we checked in with this car, Nissan had announced that it was going to be a pure battery electric vehicle and we discussed what it would take to make that happen. It seems that since that article was written, Nissan has come to the same conclusion as almost all of the other automakers trying to produce green supercars: hybrid is the way to go. The cost, weight and range of current battery technology is still not good enough to be the foundation of a performance oriented car. Electric power specs mentioned in the video are prefaced with “when running in pure electric mode” which probably means the ZEOD RC will be a series hybrid. I will update with more information as it becomes available.

In this first chapter of the ZEOD RC build, the Nissan engineers showcase the carbon fiber main tub. They talk about some of its unique features which mainly revolve around driver safety. Nine months is all the time that Nissan will have to complete the construction and testing of the car. Spaniard Lucas Ordóñez, the winner of the first Gran Turismo Academy competition, will be the ZEOD RC’s test driver. The official public debut is scheduled to occur at the World Endurance Championship race at Fuji Speedway with Michael Krumm behind the wheel. Lets hope the Deltawing based ZEOD RC will usher in a new era of green race cars. We will be following these build videos very closely.
