Broken records dominate 5th Speed Championships
Summer 1979, p. 1
Ontario Motor Speedway was, this year, the scene of both numerous traffic citations and long awaited jubilation. Interestinly enough, however, the most jubilant of all were the cited themselves. The reason? The citations were strictly ceremonial; issued to honor the first purely human powered vehicles ever to break the national speed limit of 55 mph. The occasion was the Fifth International Human Powered Speed Championships, held by the IHPVA and sponsored by BIKE WORLD Magazine.
First to earn the coveted citation and, thus, winners of the $3,000 Abbott Prize, were Butch Stinton and Jan Russell who powered Northrup University’s “White Lightning,” to a speed of 55.85 mph over the 200 meter timing traps on the very first official run of the event. White Lightning was not the fastest machine at the competition, however. The highest speed of the day was recorded by a brand new supine triple driven by Leonard Nitz, Scott Andrews and Dave Grylls. Together, these three scorched to a 57.07 mph run late Sunday. Also earning a ceremonial speeding ticket was the Phil Norton/Tom Nysether tandem that topped out at 56.56 mph.
200 Meters, Multiple Rider Vehicles
In keeping with a trend established some three years ago, multiple rider vehicles dominated the ‘79 competition in the 200 meter event. Only two single rider vehicles out of about 32 entered were able to approach the 50 mph mark. In the multiple rider category, on the other hand, four of the 10 or so machines broke 50 — each several times. Aside from the three over 55 mph machines, a new vehicle dubbed “Thurgood” built by Norm Ogle and piloted by Norm and his brother Charlie, topped the 50 mph mark with a final recording of 50.61 mph. Also in the ballpark was Tom Rightmyer’s handsome aluminum monocoque tandem that reached 48.74 mph with Adam Speth and Glen Baldwin providing power.
The winning of the $3,000 Abbott Prize was the weekend’s major accomplishment. First offered by Dr. Allan Abbott after his retirement from competition at the 1977 I HPSC, the prize was originally intended for single rider vehicles. Later it was changed to accommodate both single and multiples considerably broadening its chance of being captured. Singles were given a 1 mph handicap at 54 mph, while multiples had to achieve the full 55 mph. Despite the change it was Abbott’s hope that it would be won by a single after several years of competition.
Perhaps due to the swiftness with which the prize was won, the feat was not greeted with overwhelming enthusiasm. It seemed that everyone was well aware that it would be accomplished; it was just a matter of when. Perhaps adding to the fait accompli atmosphere, first run of the event by special arrangement with the promoters, whereby the team agreed to wait until the ‘79 IHPSC to make an official run at the prize, rather than do it on their own. Also contributing to an almost blase feeling was the fact that many believed that 55 mph had been broken at the ’78 championships. At that time during an almost flawless run that saw White Lightning’s speedometer hovering above 55, the track’s timing mechanism failed, leaving the Stinton/Russell team without an official clocking. The news of the timing failure was greeted with disbelief, for the team was sure they had won the prize.
The official 55+ mph run of this year was made in the thick fog that plagued the hour record vehicles and was actually accomplished in a slight head wind. The pricewinning White Lightning vehicle of this year was basically the same supine tandem Tricycle run in 1978 with the addition of hand cranks for the stroker and covers for the wheels. These refinements plus the accumulated experience of the pilots put the Chris Dreike, Tim Brummer, Don Guichard creation over the top and into the money.
Stroker Butch Stinton commented after the Abbott Prize winning run, “I feel great; especially after we had to wait a year to get it.” Pilot Jan Russell was ready for more. “I feel we can go taster,” he said, “we were accelerating all the way through the traps.” And faster they did go, posting a top speed of 56.92 mph by the event’s end. The Abbott Prize will be split five ways among riders and builders.
Almost upstaging White Lightning was a three rider vehicle dubbed “Vector.” Vector took first place over-all with speed of 57.67 mph. A product of General Dynamics engineers Al Voight, Steve Wojcik, John Speicher, and Doug Unkrey, Vector was brand new to the IHPSC competition. Propelling the vehicle was a powerhouse trio consisting of pursuiters Dave Grylls, Scott Andrew and Leonard Nitz.
With a squat profile of just 25″ in height and 22 feet in length, the triplex was constructed of steel tubing covered by Kelvar plastic shell. All three riders assumed the prone position with the two rear riders pedaling with both feet and hands via handles attached to the pedals of the rider in front of them. A 195-inch gear was pushed by the riders. Vector rolled upon four 18″ sew-up tires.
Nitz, the pilot, commented that “it handles perfectly … I had plans to ride a single, but then when I saw this machine I said forget the single; I said this is a good machine. I’m not going to waste my energy on anything else.”
News that the Vector team had exceeded 57 mph and nudged out White Lightning for first place greeted the riders upon their return to the pits. The scene was pure jubilation. “We kicked it a little sooner,” said Nitz, “because we discovered we were hitting top speed right at the end of the run … it takes hardly anything to keep it rolling after you’re up to speed.”
Decked out in a clear mylar fairing, the Phil Norton/Tom Nysether vehicle was the third machine to exceed 55 mph. Like White Lightning, an official 55 mph had eluded them in ’78 and they came prepared to correct this situation in ’79. To accomplish this, changes were made to both the human and aerodynamic aspects of the vehicle.
To begin with, an alternate team was assembled consisting of Jeffry Ash and Leigh 8arczewski. With a silver medal in the World Tandem Sprint Championships, this team seemed the best bet for shoving the Norton Machine over the top. The familiarity of Nysether and Norton with the machine proved more important, however, as Ash and Barczewski could not top Norton and Nysether’s runs. It also showed the importance of engineering over muscle power in the realms of streamlined vehicles. Ash and Barczewski only made runs on Saturday, however.
Aerodynamically, the vehicle was improved with a new laminar flow fairing. Made of clear Mylar instead of Dacron as used last year, the fairing was designed to operate under an entirely different aerodynamic principle than the old one. Rather than reducing frontal area to slice through the wind, the new fairing was designed to produce the effect of laminar, or “attached” air-flow, whereby a layer of air remains on the skin of the fairing and serves as the surface over which the air being pierced, flows. Also altered was the gearing, up from 172” to 187”.
200 Meter, Single Rider Vehicles
Gardner Martin and Nathan Dean put five years of refinement plus Fred Markham to work to become the first machine to break 50 miles per hour (50.84 mph) through the 200 meter traps. In the process they nipped Therio/Van Valkenburgh out of first place by 1.07 mph, and broke the latter’s two year grip on the single rider championship.
When the Martin/Dean vehicle first ran in the early years of I HPSC, it suffered badly from stability problems and was the victim of more than one crash. With greater experience, changes have been made, such that for the past two events it has earned a respectable place in the IHPSC competition. “One of the most critical improvements” said Martin at this year’s event, “was learning how to make it handle.” Ten major changes were made to the front end of the two-wheel prone vehicle before it was discovered that the rear wheel was in the wrong place. “We moved the rear wheel behind the crank — instant stability,” said Martin. Guided by a 24” front wheel and powered by a 27” rear wheel, the machine stands 30” high and is 20 feet long.
A challenge on the 50.84 mph record by Ralph Therrio was abruptly ended when he crashed into a camera tripod. Therrio had relaxed his grip on the hand and foot powered Van Valkenburg creation and suddenly found himself off the course and headed toward the tripod. The result of the 45 to 50 mph impact was a damaged fairing, crushed front wheel and broken front end. The camera didn’t fare much better. Therrio only sustained a bruised hip and chin.
While the Martin/Dean and Van Valkenburgh/Terrio vehicles were the only truly competitive single rider machines, innovations in this class were strongly present. Also evident was a much larger number of entrants: 29 singles listed in the program, to only 8 multiple rider machines.
Among the innovators were four lineardrive vehicles. One built by Steve Ball and ridden by Mario Eskabido was operated by a push-pull linear drive utilizing both hands and feet from the prone position. The three wheels on the machine were made of a honeycomb material with a thin bead of molded-in-place solid cast polyurethane tread for tires. Wrist motion at the front handles steered the vehicle. A cluster, chain and two toe clips were the only standard cycle parts. An additional entry in the hands-and-feet linear drive category was a vehicle built by Alex Brooks. Unfortunately, Brooks’ vehicle snapped a cable during an early run and did not compete. Another linear drive machine was built and entered by Peter Johnson.
Johnson’s machine utilized a supine position and operated off of foot power only. The fourth linear drive vehicle was named Loco-Motion and featured hand and foot power via an intricate arrangement of springs, pulleys, tiny sprockets and cables. A low profile of 23 inches was achieved through the use of the prone position and tiny 12 inch soapbox derby wheels. A “breadboard prototype,” builder Willmot White built it primarily with practicality and the one hour event in mind.
Constructed of a maze of small diameter tubing, an entry by Riverside Bicycle Club builders Blaine Rawdon and Dave Blanding brought back memories of the old “Bird Cage” Maserati racing car of the early 60’s in its framework. The four 20” sew-up tire wheels were canted inward for added stability and the entire fairing was made of custom formed styrofoam covered with ultra-thin fiberglass. An hour record entry, it suffered from a number of complications including a late start and lack of rider training for pilot Jerry MacAulay.
Despite this display of innovation, only the Van Val ken burgh and Martin/ Dean machines were successful at the 200 meter timing traps. Recalling the abysmal beginnings of the Martin/Dean vehicle, however, it is clear that any one of these singles would be record setting prizewinners at future speed championships.
One Hour Record
The 55 mph barrier was not the only goal to be reached at this year’s event. Saturday’s first event was an hour record attempt. Pedaling through “pea-soup” fog aboard the Kyle/Teledyne streamliner, Ron Skarin set a new hour distance record of 31.88 miles.
Conditions for the hour run were extremely poor. Ensconsed in a heavy fog, all of the enclosed vehicles had to grope their way around the oval auto racing circuit, never sure of what lay ahead or behind.
These conditions necessitated an unscheduled stop on Skarin’s run, during which he punched out his windshield and donned a pair of undershorts over his head to keep condensation from blinding him.
Despite the trials and tribulations of fog, Skarin found his hour run to be relatively easy. Commenting on the recordbreaking effort afterward, he said, “It went by unbelievably fast … it was like an hour of riding (a standard bicycle) at 15 mph; that’s what the effort felt like.” Clearly, without the pit stop much more could have been accomplished.
The fog also resulted in the first two-vehicle crash of the IHPSC’s five year history. This occurred during the hour record run when Mark Capron, piloting his and Alec Brooks’ “Bun-Burner” — one of the original I HPSC machines — crashed into the back of a much lower new creation called “Locomotion.” The altercation sliced a large gash in Capron’s hand and created a massive hole in his vehicle’s fairing. Locomotion’s plexiglass fairing was shattered at the rear. Capron was moving at 10 to 15 miles per hour faster that Locomotion upon impact according to team members. Raphael and Vincente Gomez earned second place aboard a standard fairing covered tandem. Their distance was 31.33 miles. Third place fell to Gerry MacAulay, who rode a supine single built by Blaine Rawden and Dave Blanding of Riverside.
35 km Road Race
For the second year, another LeMans style start road race was run, this one for a distance of 21.6 miles (35 km). Utilizing the 2.7 mile (4.3 km) road circuit, Fred Tatch won the event averaging 29.88 mph (48 kph). As expected, the standard bicycles with only front fairings got off first, but within a lap the full fairing machines were in the lead, Tatch well out in front.
The road race is the favorite event of Dr. Allan Abbott, who looks to the IHPSC as a means for encouraging the development of human powered vehicles that are practical for daily transportation. Tatch’s victory was a major advancement in this regard, inasmuch as he uses the same vehicle for his daily commute to work in Eugene, Oregon.
