SpeedMaster SB and BB 671 kits

The nice thing about Roots supercharging is o plumbing, instant boost, massive low end torque without the extra costs of a hair dryer system, supercharger or turbo. Even more so needed if the pressure and heat rise high enough to demand an inter cooler.

With the Roots supercharger, if cooling is needed, a water cooled system can be set up under the blower and simple plumbing is used. On a turbo or centrifugal, the plumbing to and from the internet cooler can be a big PIA and pricey.

What I like about pressuring an engine is that even at modest low levels of boost, the returns are really good. 9psi is a wonderful thing.
