All,
I was on the Auto Speed website (Australia) the other day and they had a series of articles on using an airpressure sensing device to control a whole host of things (air cleaner indicator, intake water injection controller, speed triggered controller.) What I had in mind was a device to shut down the electric fans once the car achieves around 45mph.
Unfortunately, the pressure sensing device is no longer available through Auto Speed. I contacted the manufacturer, but they mainly sell to OEMers. In order to do a direct purchase, I would have to buy 20 of these sensors at around $15/each. The remainder of the circuitry is fairly simple and could probably be purchased at Radio Shack for less than $20 or through Auto Speed for around $5 plus $8 shipping. (This circuitry provides an anti flutter shut off delay and a transistor controlled step up relay so that an automotive rated relay can be triggered.)

The question is would enough people be interested in this to warrant purchasing the minimum quantity of sensors??
