The Big Bertha series is our largest pump and is available in a 6-stage configuration as standard. It’s ideal for larger drag racing engines such as Pro Mod and PS mountain motors. The Hemi version mounts directly to the original Hemi pump location and is available in 1–5 stages. It’s widely used in Pro Mod, Funny Cars, and Top Fuel applications.
It’s available with V-band mounts in 1–6 stage setups with left or right rotation. It’s also compatible with sprint car engines for achieving maximum vacuum levels. Pressure sections range from 21–32 mm (0,826–1,102”), while scavenge rotors feature 43 mm (1,693”).
