BDL's new monster, all billet, is the Top Fuel Street Drive belt drive. The all new 14mm x 85mm wide (3 3/8 inch) belt is the same as the top fuel racers use on the 600 plus horsepower machines. The all newly designed kevlar clutch consists of nine 6 3/8 inch diamter friction plates and 11 steels. The special pressure plate uses up to 9 springs for varying spring pressure to accomodate any size motor on the market.
