Grand prix de Silverstone 1987 en Superkart (une des épreuves du championnat du monde) remportée par Eric Gassin (sur Nissag/Rotax). Eric Gassin remportera ce championnat du monde 1987 et deviendra ainsi le premier champion du monde français de l'histoire du karting .
@@thethirdman225 Fastest lap times in the dry around the original 2.927 mile lap (without the Woodcote chiicane),was 1min 29 seconds,118mph average. Around 140mph on the Hanger straight.
@@nicholasellis5965 My point was that it's lap times that are importand. Sure, you like to have good speed on the straights but not if it costs you somewhere else so lap times are the ultimate arbiter. So a speedo is unimportant.
@@thethirdman225 Back in the 1980`s gearbox karts had an electronic rev counter only ,no data-loggers back then. (I was directly involved with gearbox karting for 9 years from 1977-`85).My reply was mainly aimed at the people on here who are unfamiliar with karting.I fully understand your comment about consistant lap times,i raced cars myself for 12 years.At Silverstone in the 1970`s/`80`s even in the top 250 International Superkarts, really accurate timing was pretty difficult as no karts carried transponders back then.The timekeepers would often only take lap times of front-runners,with some quick laps invariably getting missed.The karts lap times at Silverstone`s (3 mile lap) were often affected by wind-direction or ambient conditions which did make a difference.Karts did not have the power outputs as seen in the current gearbox 2-stroke engines.Gearing for a long circuit was critical,often needing fine tuning over the weekend as weather,temperature and wind direction altered.Lap times could alter race to race as engines,carburettors,gearing and tyres were adjusted to suit the circuit and conditions,no `sealed` engines back then and all classes were aircooled motors until 250 Int.allowed watercooling in 1981.The aircooled engines were generally less reliable and more affected by ambient conditions which did affect lap times.However the short circuit karting scene was always about a good handling,well set-up chassis which gave the driver confidence allowing corner speed to be carried onto the straights.Long circuits needed plenty of horsepower and a well balanced crank.Often 250 International (Superkarts) top speeds were suprisingly low around 130-140mph probably due to a larger frontal area which compared with a racing motorcycle of the same engine capacity,the bikes top speeds were usually greater.Karts have always had much higher cornering speeds than most bikes and a lot of cars.
Yes, had great times there, karting at it's very best 👍

still miss that place , best races ever
Great Times Lennart
Race doesn’t start until about 16:00
12:00 No idea how fast they go because they have no speedo? How about you carry a phone and use GPS?
Lap times.
