671 / 871 Blower Base Gasket

The 671 / 871 Blower Base Gasket from MR. GASKET is a crucial sealing component designed specifically for Roots-type superchargers, particularly the 671 and 871 models. This gasket is essential for high-performance engine builds where positive displacement blowers mount directly to the intake manifold. It is particularly useful for those assembling street engines or dedicated competition vehicles.

Engineered to withstand the extreme pressures and temperature cycles of forced-induction systems, this gasket prevents boost leaks that can undermine tuning efforts and power delivery. The material used in the gasket ensures consistent sealing across repeated heat cycles without degradation, which is vital for maintaining performance. Proper installation is critical; it requires careful bolt torque sequencing and clean mating surfaces to ensure a reliable seal.

Mechanics and engine builders working on Roots-type supercharger installations will recognize this gasket as a necessary consumable. When investing in high-performance blower components, fuel systems, and tuning, replacing the gasket during any blower removal or engine refresh is essential to maintain optimal performance. This gasket is a small but vital part of ensuring your engine runs at its best.
