Upping the Ante – JFC Racing Dials in v8 Power for Its Wolf Chassis at the 25 Hours of Thunderhill

JFC Racing has been bringing its Wolf chassis to Thunderhill for a couple of years now, and it’s usually one of the fastest ESR cars on the track. Last year the car was equipped with a Honda K20 engine, which was good for 240 horsepower and a fast lap of 1:41.819. But the engine didn’t make it through the night after spiking oil pressures necessitated an engine swap.
For 2016, JFC Racing upped the ante by fitting the car with a Hartley V8. At 2.8 liters, the Hartley V8 dyno-tested at 430 horsepower with “conservative” camshafts. Splayed at 90 degrees, the Hartley V8 block is machined from one piece of billet and topped with cylinder heads from a 1340 cc Suzuki Hayabusa motorcycle engine.

Corvette Takes on Thunderhill

The last time a Corvette raced in the 25 Hours of Thunderhill presented by Hawk Performance, George W. Bush was still in office and C6 Corvettes were barely a year old. That seems like a long time ago.
NASA SoCal’s T.C. McNett was the crew chief of that team. He said they only raced it one year, because they had clutch problems and some issues with the fuel cell, and dropped out before the checkers flew.
Obviously, the Chevrolet Corvette is a perennial favorite in Super Touring classes and the platform has proven itself a winner, but making it last 25 hours is a challenge.

Brothers in Arms – Team Diamond Level Motorsports Assembles a Crew of Veterans to Raise Awareness for Recreational Therapy for Those With Post Traumatic Stress Disorder

When U.S. Army veteran Tom Woods wanted to get back into racing, he also wanted to do something positive. Woods then partnered with Diamond Level Motorsports and Fisher House to bring together a group of five veterans, and himself, on a team that would take on the toughest endurance race in North  America.
“The thought process for me was that if we had a group of veterans who had all been in combat together, they could support another veteran through the trials and tribulations of a 25-hour endurance race” Woods said. “So, they’re getting recreational therapy, but they’re also a team once again, they have that brotherhood once again, and that’s something that a lot of veterans are missing when they come back home.

ESR Class – Thunderhill 2016

The front row for the start of the race was a pair of Ryno Racing Ginettas, which were large — in a literal and figurative sense. These brutes loomed over everything in the ESR class and dwarfed some of the smaller production vehicles in the numbered classes. Powered by General Motors’ LS V8s, the Ginettas were proverbial guns in a knife fight. They were in a strong position for outright victory.
The Ginettas came out swinging, leading by two laps two hours in, four laps four hours in and so forth over the Flying Lizard team, its main competition for the overall win. By sunrise the next morning, the Ginettas were six laps up on both the Lizard cars, showing no signs of slowing. Then, within a couple of hours of each other, both cars suffered right rear hub failures.

ES Class – Thunderhill 2016

For the last several years, the overall winner has gridded in ES class. ES cars don’t usually have the pace that ESR cars do, but they compensate for what they lack in comparative speed with greater durability.
That was true in 2015 when the Toyo Tires/Flying Lizard Motorsports Audi R8 cranked out 690 laps during a rain-soaked race that was one of the more challenging in recent memory. In 2016, the Lizard team faced off against two LS-powered Ginettas from Ryno Racing, which had the speed, running times upward of 4 seconds faster per lap faster.
The Ginettas also looked durable, and they held the overall lead all of Saturday and throughout the night. Twenty-three hours into the race, the Ginettas were running first and third overall.

E3 Class – Thunderhill 2016

Back in 2012, 25 E3 cars gridded for the 25 Hours of Thunderhill. Over the last four years, the class has witnessed a slow, steady decline in numbers. In 2016, six cars took the green flag.
RA Motorsports fielded two teams, and team owner and 25 Hour veteran Ron Gayman knows how to prep car to win here. His team won E3 last year. Also in the hunt for E3 glory was RJ Racing, which has two wins in the 25 and podium finishes, too.
Of course, one of the more interesting teams is A+ Racing, whose car was built and crewed by high-school students in a vocational class. This isn’t their first year. Last year the team finished fourth and in 2013 they finished third.

E2 Class – Thunderhill 2016

If you look up and down the grid before the start at Thunderhill, you notice that most of the hardware is pretty new. This isn’t a race that lends itself to vintage tin. Don’t tell that to KD Motorsports, which took a car built when Ronald Reagan was president, and took home all the marbles in E2.
Their BMW E30 didn’t have the quickest pace in E2. That mantle belonged to Team RDR Racing in the No. 34 RX-8 known as “Kermit.” Yeah, it’s green. The RX-8 was running laps 3 seconds quicker than KD Motorsports, but this is Thunderhill, where anything can happen — and often does. During an extended caution period, the RX-8 ran low on fuel and had to come in and sit because rules forbid refueling while the yellows are out. They sat for 10 minutes.
