After a winter spent in training, bike preparation, and anxiously awaiting the new racing season, K&N-sponsored flat track racer Cory Texter is back in the saddle. The 2017 season has started with a flurry of warm-up, regional, and specialty races, as well as the first round of the American Pro Flat Track series. Here is a rundown of Texter’s early season racing.

Savannah All-Star Half Mile

Texter will pilot his Kawasaki 750 in the Expert Twins class in the 2017 Pro Flat Track season

“A lot of fast guys come to this race and I was eager to see where I stacked up after a long off-season,” Texter said. “I felt good all day on both my Kawasaki 750 and Honda 450.”

The Super Singles class is open to any size engine as long as it is a single cylinder machine. Texter rode his Honda in the class. “I didn't get the best start, but I passed a couple guys and chased down the leader who was riding a super fast big bore 450,” said Texter. “I was close, but no cigar and finished 2nd.”

The Expert Twins class main event proved to be another fast-and-furious contest with the results more to Texter’s liking. “I pulled the holeshot and put in some solid laps the first half of the race.” said Texter. “When I saw I had a large gap over the rest of the field, I put it on cruise control and sailed her home for the win. I have won a couple of races here in the fall, but this was the first spring All-Star main event I have won here.”

Volusia All-Star Half Mile

The early season is all about sorting out bike set up and preparing for the season ahead

“This track is extremely tough to pass on and a good start is crucial,” Texter said. “Unfortunately, in the Expert Twins heat race, I had a terrible jump and found myself in third place. I was trying all I could to make a pass for second, but the bike wasn't working the way I wanted it to. I ended up getting passed on the last lap and finished 4th in my heat race.”

Getting a similar start in the Super Singles race, Texter’s competitive nature kicked in to full gear. “In the Super Singles class, I again got a terrible start, but I wasn't going to be denied twice, so I ended up [passing] five riders in my heat race to take the win,” said Texter.

“We made some changes to my Kawasaki Twin and I was really eager to redeem myself in the main event, but Mother Nature decided she wanted it to rain and we were scored by the heat races,” Texter said. “I ended up 7th on the twin, but I had the fastest heat race time on the 450 and won the Super Singles class. I was bummed with the final result on the twin and not being able to try the changes we made to the bike for the main event, but it felt good to get a win on my 450.”

American Flat Track Series Round 1 - Daytona TT

Texter was frustrated that a shift lever led to a Daytona DNF

“I have never been to a race in my life where there were more unknowns than the Daytona TT,” said Texter. “I prepared myself and my bikes as best I could with the budget I had, but I still wasn't sure what to expect. The track was basic, but fast and technical. To be honest, I have only raced a couple of TT events over the past few years. I ride a lot of motocross, but it's still a different animal. I qualified 21st, which I wasn't pleased with.”

There is a new knockout format to the qualifying in American Pro Flat Track this year, and Texter made the cut with a gutsy qualifying ride. “I battled hard and finished in 8th, which was good enough for a transfer to the main,” Texter said. “I train hard and I was really looking forward to a hard, long 25 laps.”

For Texter, the Daytona TT was clear and powerful evidence that the smallest mechanical part can be the difference between a successful race effort and a DNF.

“One of the biggest issues I was having all day was with my shifter. My bike was missing shifts all night long,” said Texter. “After the semi, we noticed my shifter was loose, so we swapped in a new shifter. Unfortunately on lap five in the main event, my shifter came off completely causing me to DNF.”

“I was credited with 17th,” Texter said. “I was bummed about the whole deal because I was confident I could have had a solid finish, but a mechanical like that is out of my control, so it's something I can't dwell on. We learned a lot of things that will better us for the additional TT races on the schedule. On the positive, I kept it on two wheels and came out of there with a couple of points heading into a couple of race tracks I am really excited for.”

Clash of the Concrete Indoor Race

Texter's Daytona week ended on a high note with a concrete oval win at Daytona Bike Week

“I was tired from the National the night before, but racing motorcycles is my job, so I got my bike ready and went to work,” Texter said. “There were some good riders in attendance with a good purse on the line. Harley-Davidson broadcasted the whole event on their Facebook page, which was pretty neat. I do well on these concrete indoors. I ended up winning my heat race and the main event. Although it wasn't a Grand National, it felt good to redeem myself from the night before and grab another win for my sponsors during Daytona Bike Week.”

Texter is primed and ready for round two of the American Pro Flat Track season. The Georgia Short Track will be held at Dixie Speedway in Woodstock, Georgia. “Thanks to all of my sponsors for all of the support this season,” Texter said. “I know that is a cliché statement, but without all of the support, I wouldn't be able to call this my job and I am truly blessed to have a great group of supporters behind me this year.”

K&N filters are mounted inside custom covers on both ends of the motor

Initially designed for powerboat applications, the crew at XVI Power said that they’d love to see the engine mounted in a few street rods or custom cars. Despite the fact that the engine has four more cylinders, it’s only a foot longer than a Viper V10

The concept behind the motor is that as high-end boat V8 engines are beginning to reach 1,600 horsepower, they’ve become near-race motors with all the maintenance and durability issues related to developing over 200 horsepower per cylinder. And while race teams understand and plan for the kind of abuse a race engine sees, boat owners, perhaps a tad unrealistically, expect these heavily-tweaked motors to provide reliable, long-term service.

The alternative, as XVI Power saw it, was to reduce the load on any single cylinder by increasing the total number of cylinders. Therefore, a cylinder that was expected to produce the stressful 200 horsepower now delivers a more rational 100 horsepower per cylinder, according to XVI team member, Tom Robinson.

The V16 engine in all its glory, the LS design basis is clear even from this view

That gap in the cylinder bore allows for the use of Chevrolet LS cylinder heads, from mild to wild, at the owner’s discretion. In fact, many parts come directly from the LS design, with the only major parts coming from XVI Power being the engine block, crankshaft (supported by ten main caps machined into the oil pan and using big block bearings), the oil pan itself, and the gun-drilled single piece camshaft. Duramax bearings are an option for supercharged or turbo applications. Valves, lifters, rockers, manifolds, many fittings, gaskets, and seals, are all standard Chevrolet items so when any maintenance is required, the parts are close by the marine repair shop.

Here you can get a good view of the piping on the water-cooled headers

Performance is staggering. The basic engine runs with the ignition firing every 45 degree, making for a very smooth running engine regardless of output. And that range of output starts at the basic 900 horsepower and moves up through to a 1,400 horsepower model, all normally-aspirated. Forced induction will be offered latter with a 1,600 horsepower supercharged version and 2,000 horsepower with a quad turbocharger setup. We can’t wait to see the first show car with an XVI engine.
