Hmm, I'll have to print out these dyno runs and take them to some friends to see what they can glean from them.
What did I expect? (I don't think that I ever let anyone know what my opinions were on this device).
I expected it to work - somewhat at least. I had a strong feeling that it would not drain on the car while running, enough to counter the effects of it's added boost. The fan is a very compact, high-powered fan that is not like the CPU cooler fans. Mark was telling me that it was the only motor that could support their application, and that only one manufacturer made it (somewhere in Europe, I believe). This was one of the reasons why he had supply problems.
It is an interesting question, as to how much extra boost can you give without draining any extra power from the alternator. In theory, you would want to carry around an extra battery to power the device so that it doesn't load the alternator, but that, of course would add extra weight.
There's a reason that we haven't sold these on the website - I really didn't know if they worked. Even with the low HP increases that Thom found, I'm not sure if the $300 cost is worth it.
