You'll need a power inverter, probably a high amp alternator, a switch connected to your throttle so that it will only activate at full throttle and of course......A Kirby vacuum.

Install the inverter and switch, strip the Kirby including the handle and wheels, mount the Kirby on almost any current port fuel injection engines' intake tubing. Make sure you have some way of regulating the amount of pressure from the vacuum. I envision cutting a square hole in the intake tubing and placing some type of butterfly or sliding device to close the opening for more pressure. You'll need to get on a dyno and play with it to get it just right. And the best part is that when you go camping, you can use the built in extension cord on the Kirby to power common household devices!
