MS-75 Regular Location: Adelaide Registered: June 2002	Re: Supercrown-1, Dynapack Dyno-NIL Mon, 31 October 2005 09:16 Mick-prior to the day I called the workshop running the comp to check what the program was, and the owner specifically warned me that with the latest version shootout software they were using that the numbers would be down 15-20kw. True to his word, on my first run before the BFG's went up in smoke it went 361kw, 20kw down on one dyno I've used and 30 down on another (all using the same ramp rate and similar atmospheric conditions). It took another 1.7 pounds to pick up the 30kw. Most others that were used to running on chassis dyno's noticed it as well(including the Supra)-but as I said before, it was a level playing field. As for 2.3 big HP motors not maxing out dynos, I'm not at all surprised. Although rated in HP, the limiting factor in dynos is their ability to register torque-power just comes with torque at revs-which I'm sure you already know. Although the 4.5L may be down on power to these smaller displacement engines, it will be making far more torque-unless these motors are running in excess of 45-50 pounds boost. The crown may not have been in the running to hit the HP ceiling of the Dynapack units due to it's low revving nature, but it was capable of exceeding the max torque limit with apparrent ease.(well in excess of 1000nm by around 3000rpm, with max at 3600rpm or so) The Dynapack system uses a single type of mechanical unit, and the different levels of torque handling ability (and hence max power rating) are goverened by differing levels of software-for which they charge increasing amounts.(very smart method as far as R&D goes as it means the mechanical development cost is greatly reduced) As for how much the blue whale is ACTUALLY making-it's anyones guess, but crunching the numbers from the 130mph trap speed and race weight, at 19psi it's around 600hp at the flex plate. Once I pull it out and mod the motor internally I'll engine dyno it for an accurate number-but for now, a 1/4 mile trap speed doesn't lie. If the dyno was 25% over, there's no way a vehicle with this kerb weight (including me, well over 1600kg/3500lbs wet) would even come close to 130mph with only 400hp.
