the front tires have to be strapped down or the damn thing will wheelie and come off the dyno. i use to build high end sand cars with 1100 hp LS1 twin turbo's. Dyno time was FUN!!!. had a few times where we couldnt keep the car hooked up on the dyno drum and it would start smokin the tires and throwin chunks of rubber. good times man, good times!
