Pete,

I'm always skeptical whenever an AfterMarket Company throws Dyno Testing into the Mix. I mean there's Dyno Testing and then there's Dyno Testing.

One Company's product was tested on a Dyno, and they did get the Readout they wanted for Advertising purposes - they did however leave out the fact that the Engine needed a total rebuild once they were done - but the Truth in Abvertising Guidelines were met.

There are so many variables on a Dyno that a repeatable, verifyable result is frequently unachievable. If they don't publish the Methodology, it's all bunk!

People put Great Faith (read Too Much Faith) in someone else's Dyno results. I just read an article about the Guy from Wisc. who invented the Rolling Dyno. He Tried to market it to AfterMarket manufacturers. At $25k/copy, it was a tough sell. One Major Manufacturer flat out told him, why would I spend $25k, when I can market junk by placing a $5k Ad in a Car Mag and get $50k worth of Sales from it..??

But, the Dyno gain popularity and the Faith of the Average Joe. So today, Dyno Testing has become De Rigeur for anybody with a Fancy, New, Widget. But, there is a wide degree of accuracy in Dyno results, often greater than the increases boasted by the Manufacturer. If say the Super were Free-Wheeling, then that much boost may be attainable, but in real life, I doubt it.

It takes a lot of energy to produce 18PSI of Boost. The impellor needs to be very precise, not to mention the torque and power of the electric motor. These things have great inefficiencies - they do not transfer Energy well due to Mechanical Loss. It is fairly simple Mathermatics - there is only so much usable Work to be derived from 1 Horsepower. Take away Mechanical inefficiencies and a Unit has to draw waay more power than the actual work it's producing. The Blower is not an innovative technology - it is no more efficient than a Blower powered by another means. The Electric Drive Motor isn't innovative - no more powerful than any other, so I'm not convinced.

But, if I ever do find a way to make more from less, I'll have a Car Collection which puts Seinfeld, Leno, and Ralph Lauren to shame...

Happy Motoring!... Jim'99
