OK, maybe. If you turned it pretty fast by using a real small pulley on the smog pump. My experience has been with pumps on engines we were fooling with, and with the standard pulleys, there was not much volume when we took off the output plumbing. I would be concerned about heat buildup turning a pump fast. The heat transferred to the air would increase chances of detonation problems. And I would really worry about smog pump durability at high RPM's. The ones I have seen don't have any oil connections to circulate cooling oil like most real superchargers. And don't they have plastic vanes?

Before I spent a lot of money and time fabricating a pressure box and other stuff needed to make one work, I would do a test on long term durability of a smog pump at high speeds.

But you are right, it might be fun. And at least the smog pump itself would be a cheap start to the project. I can see big expenditures to make it all work right. OK on a play toy, I would not try it on something I was really going to use to do work.

I have mused about adding a very small turbocharger to my 641Diesel to up the power some. A friend of mine has a track hoe with a smaller diesel than my Ford, but with one of the smallest turbos I have ever seen. It has serious power and the hoe will do amazing things. It seems easier to get a turbo to work right on a diesel than a gas engine.

Now I have something else to think about. What do you think about using a smog pump to pressurize the air intake of a small diesel?
