I did a test about a week ago to get some idea of what it takes to turn a Procharger. About the only thing I could test easily is fuel economy differences. This wasn't a perfect test, but I think it still gives some idea of what is involved. I have driven the car to work running around 60 mph on the interstate and the speed limit everywhere else and have gotten around 12.5 mpg as my best - when I play it gets drastically worse. I took off all of the supercharger stuff and put on a Holley 3310 and reduced the size of the idle feed restrictions until I got similar air / fuel ratios as the blower carburetor. They both were running around the high 13's to low to mid 14's while cruising depending on throttle postion, load, etc. This setup got about 1 mpg better not pulling the supercharger. I personally though it would have been more difference than that, but it doesn't appear to be. Clay
