In the summertime of 2018 I met the small Danish drag race team who call themselves True Cousins at Mantorp Race Park, Sweden. The Cousins are Hans-Henrik Thomsen and Glenn Ellegaard Nielsen, and at that occasion their electrical doorslammer drag racer TC-X nailed the 1/4 mile electrical world document at 7.98 seconds. Their electrical drag bike Silver Bullitt didn’t meet their objectives on the time and needed to suffice with a 7.78 second 1/4 mile time.
However this yr, their new Silver Lightning has claimed the throne because the quickest electrical drag bike ever, beating the earlier document at 6.94 seconds set in 2012 by Larry “Spiderman” McBride.
Hans-Henrik Thomsen tells the story to Ingeniøren that I’ll translate excerpts from:
Danish electrical motorbike is now the quickest of all electrical automobiles on the earth
The Danish drag racing group, True Cousins, and their electrical motorbike Silver Lightning, have simply returned house after a each nerve-wracking but in addition extraordinarily profitable effort on the English Santa Pod Raceway through the occasion “NOT The Euro Finals.”
Within the third final try (out of 9 attainable) they managed to beat the 8-year-old document over 1/4-mile (402 m) for electrical automobiles, which stood at 6.94 seconds. The motive force was, as at all times, Hans-Henrik Thomsen, whereas it’s Glenn E. Nielsen who has constructed the pace monster on lithium batteries, Silver Lightning.
However there was not a lot to hope that it might flip right into a document after the primary 6 makes an attempt on Friday and Saturday. The most effective time as much as that time was 7.15 seconds, and the traits of the observe have been very totally different from the tracks that the group is used to racing in Sweden. The phenomenon of “tire shake” (the rear wheel deforms and jumps) pushed the Silver Lightning too far to the aspect of the observe whereas there have been violent tremors the primary 200 meters down the observe — each these points have been an impediment to clocking a superb run.
Finally the issues bought sorted out and the primary race on Sunday resulted in a brand new preliminary world document of 6.87 seconds and 307 km/h (191 mph) crossing the road! Silver Lightning steered higher and tire shakes have been lowered a lot that the document run might be accomplished with out drama. The British viewers (“solely” about 5,000 attributable to Corona restrictions) had already proved to be glorious they usually have been elated — particularly after seeing 6 futile makes an attempt in a row — when the document was lastly realized.
By the way, the 1/8 mile at 201 meters was unofficially additionally the most effective on the earth at 4.37 seconds and 0-100 km/h (0-62 mph) was at approx. 0.9 seconds through the first 18 meters (60 ft time of 1.08 seconds).
After a failed try afterwards with elevated energy, which solely became wheel spin attributable to an excessive amount of energy, too excessive tire stress, and lack of grip, it was time for the final try. With one final hope of an enchancment, the ability was dialed down a bit once more and the tire stress was lowered to 9 psi. After a superb begin with roughly 80 meters on the rear wheel, Hans-Henrik by accident slipped a bit on the throttle together with his glove because of the violent vibrations, leading to a interval of 1.5 seconds at 20% wanting full energy. However nonetheless the document was improved fairly a bit to six.86 and a pleasant 314 km/h (195 mph). Knowledge logs subsequently confirmed that the time likelihood might have been round 6.7 seconds, however that is still to be seen within the coming season.
All in all, a superb end result, which once more exhibits that with innovation, technical ingenuity and a substantial amount of perseverance, these cussed Danes can assert themselves on the earth in many alternative methods. True Cousins began 12 years in the past with the primary small motorbike with two 12 volt lead acid batteries and an output of 12 kW — Silver Lightning is roughly 100 instances extra highly effective with its 1.2 MW (1,200 kW) peak output battery pack.
In 7 weeks (over 2 occasions) the group has improved their quickest time by virtually a second from 7.80 to six.86 seconds, which in itself is kind of an achievement. And now this bike is the quickest working on electrical energy on this a part of the universe. Nonetheless, 1.36 seconds stays right down to the quickest bikes with inner combustion engines — Prime Gas Bikes — that holds the document at 5.50 seconds. However time will inform how low you may go …
