1997 5.9L Magnum Roots Supercharging and Fitment

Just catching up on this thread. I'm pretty well versed in 6-71/8-71 builds from "back in the day". With an intercooler you would be damn lucky to push 10psi on pump gas. Without you're probably safe in the 6psi range. Old school roots blowers generate crazy heat. Truthfully after 6-8psi it's a waste. You hardly make any more power. Most people aren't familiar with these anymore. A roots build is usually in the 6-7 CR range coupled with a cam that bleeds cylinder pressure. The crank snout deal is real too.

They look cool, but they are not in the same ballpark as centrifugals, helix, or turbos.
