Re: Basic supercharging questions.... (garagedweller2)
6-71 is for a 6 cylinder engine with 71 cubic inches per cylinder. So it would be for an engine with around 426 cubic inches.
8-71(what I'm going to be using) is for a 8 cylinder engine with 71 cubic inches per cylinder. So it would be for an engine with around 568 cubic inches
10-71 is for a 10 cylinder engine with 71 cubic inches per cylinder. So it would be for an engine with around 710 cubic inches.
That doesn't mean that I couldn't use a 10-71 on my motor though.
Also 8-71s originally came on Detroit Deisel motors. With the 8-71 removed form these motors they would not function at all.

Re: Basic supercharging questions.... (Schmucker)
The faster a blower us spun the more heat it generates so you are bette to install a larger blower and spin it undrive or slower then take a small supercharger and overdrive it.
This said I spin my 8-71 15% overdrive to get 12 pounds of boost. The overdrive also shows up on the low speed where just normal pulling away yields about 5 psi without even trying
