Mark my words. There will come a time when a Murf car will become "the official chassis of NHRA drag racing" Much like the official fuel. You will not be permitted an alternative. It will have more to do with political clout and potential litigation than safety. The fact that Don Long, Davie Uyehara, Bob Meyer and Marc Rowe were asked to leave the chassis committee sickens me. Just because a builder uses FEA or ANSYS does not impress me. I suggest you read a book "
To Engineer is human." A computer wont tell you where to place a particular wall thickness or diameter tube. it will simply show you the results of placing that tube in a perfect world that can not possibly take into consideration inertia, engine torque, vibration, wing load, Side wind load on body panels and wing spill plates, Chassis twisting load as a result of mid course steering correction. CG change as a result of chassis arch and tire growth. All combined. Don Long's record speaks for itself. How many have been killed in Murf cars in the past? How many of Don Long, Davie Uyehara, Bob Meyer and Marc Rowe's cars have been ripped in half at chute deployment? I rest my case.
