MajicBus, your video was the inspiration for this entire project with using a DC controller motor, which I watched a few day's ago.
Have a few questions. In your video comment section, you state that you changed and upgraded the controller unit being used because of the whine, but it didn't state specifics. You've just mentioned in this thread that you used a 3-speed resistor from another car, but what car. Also, I agree with the concept of mounting it in the airbox, but where to cut the hole. Also, where did you mount the dial so as not to make it look obtrusive. I agree that the factory switch settings are not the best and I'd want to duplicate what you've done for it sounds fantastic.
