Those in "the Know" are keenly aware that the import or compact industry is technologically driven. Complete stand-alone engine management systems, on-board air/fuel ratio monitors and even data-logging system are a common site on many high-dollar import/sport compact racers. Even street cars are attaining remarkable performance. It is apparent that the more the industry matures the more technologically advanced we become. One area the industry has showed strides in advancement is the use of chassis dynamometers for dyno tuning or product testing.
It is fairly common that any performance product evaluation must come complete with a dyno graph or the evaluation is deemed worthless. Some product packaging even has the company's own dyno testing graph on the box. Unfortunately, much of our dyno usage has revolved around a two-wheel-drive Dynojet making the four-wheel-drive vehicle owners a little left out. With the introduction of the Subaru WRX and hopefully the Mitsubishi Lancer EVO VII turbo next year the cry for four-wheel-drive dyno tuning will be more resounding than ever before. Fortunately, Dynapack USA has released its 2WD and more importantly 4WD dynamometers.
In the past many 4WD owners have relied on the drag strip for performance data. Unfortunately, no driver performs perfectly each time down the drag strip causing an inconsistency in data acquisition. The only accurate way to measure performance is on a chassis or engine dynamometer. With the introduction of the Dynapack 4WD dyno in the U.S. more enthusiasts can benefit from the use of dyno tuning.
One of the biggest benefits of the Dynapack system is the use of full data-logging capabilities, making tuning an engine much simpler. The Dynapack system is capable of monitoring 16 different channels of data acquisition with 8 channels of real-time display at a time. Some of the more important monitoring abilities are air/fuel ratio, boost pressure/vacuum, intake air temperature, EGT, fuel and oil pressure. With the ability to view the graphs of each data acquisition on top of one another, the tuner is able to fine tune the engine safely and more efficiently, cutting overall dyno time which saves money and preventing engine fatigue from over dynoing.
In the past 4WD owners have relied on the drag strip for performance data. With the aid of Dynapack's 4WD chassis dyno, all-wheel-drive car owners now have a new avenue for engine tuning.
