event: AHDRA Southern Nationals

when: September 17-18, 2021

where: South Carolina Motorplex, Orangeburg, South Carolina, USA

From the U.S. Nationals in Indy to AHDRA’s Southern Nationals in Orangeburg, Ryan Peery is enjoying a streak like few other racers ever. Heat and humidity, cool and dry, quarter mile or South Carolina Motorplex’s eighth—Peery has mastered them all in 2021 as he wins Top Fuel Harley races one after another in multiple sanctions, including AHDRA, NHRA, and just last weekend at AMRA.

Peery could be headed to multiple Top Fuel Harley championships this year, including the AHDRA all-American motorcycle drag racing series. His final round win against Dr. Jimmy “Mack” McMillan at Orangeburg on September 17-18 might have sealed the deal.

Qualifying number one, Peery had the bye while running consistent 4.20’s all weekend, while McMillan had to face Bad Apple Racing’s Tracy Kile—the winner of AHDRA’s Cecil County event.

“Jimmy ran some personal bests and took out Tracy,” said Peery. “He and I paired up for the final, and it looked like he was lined up a little crooked and he crossed center. Jimmy is doing a great job though. He will turn into a tough competitor with a little more seat time.”

Local second generation star Armon Furr won Hawaya Racing Nitro Funnybike, beating points leader Michael Balch in the final. “I appreciate everyone that came out and participated in the event,” Furr said first off. “I hope we can try it again, maybe this time earlier in the year. If we are going to have a race in South Carolina, this is the best track even though it is eighth mile.

“Not really much to tell about my performance because I didn’t really do anything great. Just got lucky.”

Like Furr, South Carolina’s Sam White gave the home crowd what they wanted, taking the Hawaya Racing Pro Fuel final over Rocky Jackson.

Nate Carnahan scored an easy Pingel Modified win when Stoney Westbrook redlit in the final. “Was my first win in Mod, and it was pure luck but I’ll take it!” laughed Carnahan, who was struggling all weekend with tire spin off the line.

John Shotts won Vreeland’s Harley-Davidson Super Gas 6.35 index, beating Robert Willis in the final. Shotts took the tree .039 to .049 and came out on top of the double breakout race.

“We struggled all weekend with the bike,” said Shotts, echoing Carnahan’s path to victory. “Never did figure out the problem but we ran good enough to win! It was our first time at that track and we really had a good time.”

Willis also runner-upped in Top Eliminator, losing the final round to Ken Strauss, but won Mad Monkey Motorsports Eliminator over Jason Leeper.

Jason’s son Jordan Leeper had a Luke Skywalker moment, beating his dad in the Street Eliminator final. “Wasn’t the first time,” laughed Jordan. “He’s good, but my bike was dialed in more than his was. When it came down to it, I got the holeshot and he broke out trying to chase me down.

“I’d just like to thank Universal Fleet & Tire Racing for having me as a team rider, and everyone from the AHDRA for coming out and letting the sport prosper, and a special shout out to Bill Rowe for hosting these amazing races! I’m very pleased with my bike this year, minimal breakdowns while staying consistent. I’m happy with 11.50 wins this year, but we’re on the hunt for the championship.”

Leeper’s teammate “Crazy” won Trophy.

Larry Maynhart hadn’t been to the track in over five years, and came back with a bang—winning Universal Fleet & Tire Pro Eliminator 7.00 index and falling just short in Super Pro 6.60 as the runner-up.

“I did a permanent move to Georgia,” Maynhart says about his absence. “Don’t realize how fast the time goes, but I was determined to get back racing this year.”

Maynhart was sharp on the tree in both finals, putting .040 on Cody Hayward while winning a double breakout Pro Eliminator final. He had .033 on Bob Maier in the Super Pro final, but let Maier win with a sharp 6.609. “Get the light, lose the race. I’m rusty,” concluded Maynhart. “But I had a great weekend.”

John Price won the Zippers Performance Pro Modified final over Shane Pendergrass, and Ryland Mason tamed his wheelies long enough to win Law Tigers Pro Bagger over Justin Demery,

Greg Quinn is another winning wild wheelier, picking up the MTC Bagger trophy. “Been trying to tame my bike,” Quinn said of his Kendall Johnson ProCharged, former Tii Tharpe machine. “Finding the perfect combination is tough for a carbureted bike. Still doing wheelies and climbing the ladders of the field.

“My first time running at this track and the prep was good.

“I’m blessed to be part of a history making time frame. It really started in Nahunta, North Carolina—Wood Cycles put a race on. My racing life has been blessed, and out-of-pocket is hard. Hope to keep doing just as I did in South Carolina, and somebody will surprise me with sponsorship.

“I’m just grateful for my travels, and that AHDRA has Mike Davis and Tim Hailey around for capturing the moments I don’t get to see.”

Kevin Campbell won GMS Racing Pro Open

And now Bill Rowe, his family, and the AHDRA community turn their attention to making the World Finals at Gainesville Raceway the biggest, baddest, and best ever! Be there November 6-7 to cap off a great 2021 and set the stage for a historic 2022.

Motorcycle Vibrations Can Damage iPhone cameras as per Apple

Motorcycle vibrations can degrade iPhone camera performance, Apple says

High amplitude vibrations can cause problems for the cameras’ gyroscopes

A new post on Apple’s Support forum https://support.apple.com/en-us/HT212803 says exposing iPhones to high-amplitude vibrations, “specifically those generated by high-power motorcycle engines” could degrade the devices’ camera system. The company recommends against mounting an iPhone on a motorcycle, as the vibrations may be transmitted via the bike’s handlebars and chassis.

Here’s the technical explanation from Apple:

If you accidentally move a camera when you take a picture, the resulting image can be blurry. To prevent this, some iPhone models have optical image stabilization (OIS).1 OIS lets you take sharp photos even if you accidentally move the camera. With OIS, a gyroscope senses that the camera moved. To reduce image motion, and the resulting blur, the lens moves according to the angle of the gyroscope.

Additionally, some iPhone models have closed-loop autofocus (AF).2 Closed-loop AF resists the effects of gravity and vibration to preserve sharp focus in stills, videos, and panoramas. With closed-loop AF, on-board magnetic sensors measure gravity and vibration effects and determine the lens position so that the compensating motion can be set accurately.

The OIS and closed-loop AF systems in iPhone are designed for durability. However, as is the case with many consumer electronics that include systems like OIS, long-term direct exposure to high-amplitude vibrations within certain frequency ranges may degrade the performance of these systems and lead to reduced image quality for photos and videos. It is recommended to avoid exposing your iPhone to extended high-amplitude vibrations.

The iPhone 6s, iPhone 6s Plus, and all iPhones since the iPhone 7 have both optical image stabilization and closed-loop autofocus (as noted by MacRumors, the first outlet to spot the Apple support post). Both features are also vulnerable to magnetic interference from some iPhone accessories, Apple warned earlier this year, but removing the accessories should take care of that issue.

Additionally in the new post, Apple says if you’re planning to mount your iPhone to a scooter or a moped, it recommends using a vibration-dampening mount to lessen the risk to the phone and its camera system. And avoiding prolonged regular use of an iPhone mounted to a vehicle that produces lower-amplitude vibrations is also a good idea.

Apple says iPhone cameras can be hurt by motorcycle vibrations

High-power or high-volume motorcycle engines produce potentially damaging high-amplitude vibrations, so the company says don’t attach your phone to your hawg.

If you’ve been rockin’ down the highway with an iPhone mounted on your motorcycle, you might want to think again. On Friday, Apple said certain motorcycle engines can give your iPhone’s camera bad vibes.

“Exposing your iPhone to high amplitude vibrations within certain frequency ranges, specifically those generated by high-power motorcycle engines, can degrade the performance of the camera system,” the company said in a post on its support site.

The vibes are channeled through the chassis and handlebars, so you shouldn’t attach your phone to motorcycles with high-power or high-volume engines, the company said. It said mopeds and scooters, which tend to have small-volume or electric engines, are less of a concern but that you should use a vibration dampening mount and “avoid regular use for prolonged periods.”

The problem has to do with high-tech gyroscope- and magnet-based camera systems designed to compensate for shaky shots. Such systems, like optical image stabilization and closed-loop autofocus, make automatic adjustments if you accidentally move while taking a picture.

“The OIS and closed-loop AF systems in iPhone are designed for durability,” Apple said. But “long-term direct exposure to high-amplitude vibrations … may degrade the performance of these systems and lead to reduced image quality for photos and videos.”
