"Run What You Brung" RacingThis year's Rock Island Grand Prix will feature a full "open" class where engine and chassis rules will be almost non-existent. The race will be for non-shifter 2-stroke karts up to 150cc, using various weights depending on capacity. Virtually all modern karting classes have restrictions on carburettors, tyres, engine timing (ports, ignition), head cc etc. The only things of concern at this event will be bore and stroke (to determine capacity), banning of turbos and Wankel rotaries, and no hydrazine or carcinogenic compounds in the fuel. Everything else is virtually open! “There’s your challenge to start thinking outside the box” organisers said in a statement. “Grab that old motor off the shelf and figure out how you can make it more powerful; how you can make the chassis lighter; who you can get to drive it who will do more than hold on for dear life!” “This race will assign bragging rights – for motor builders and drivers. There is no point in finishing second.” Rock Island Grand Prix president Roger Ruthhart said. The rules are simple – and there aren’t many: * 2-cycle single-cylinder, non-shifter motors only. No Wankels The Rock Island GP takes place in America on September 2-4. |
