Chassis Dyno question
Does anyone have any good information about chassis dyno's (DynoJet) and wheter they are hard on the motor. I have been told that they put a lot of undue stress on the crank, rods, etc due to "free-wheeling". However, if you read articles about DynoJet they actually state that thier Free-wheeling design put 75% less stress on components, so I'm not sure what to believe. I just put a 383 in my 68 Chevelle about 2000 miles ago. Our target was 500 hp at the crank and I would like to see what the bph is. But I don't want to risk damaging it if dynos aren't good on the motor. Any advise? Thanks!!!!

If you're comfortable doing untold numbers of full throttle pulls down the dragstrip or your local back streets, you shouldn't have a big problem putting your car on a dyno (provided, of course, that the shop is well equipped with cooling fans for the engine AND tires, good straps, etc).
