7GPM is a $hit load of flow....your talking a bucket a minute - I've never seen that.
Johnson CM30 manual states:
- 6.9 GPM with 3.3ft of Head Pressure
- 5.2 GPM with 6.6ft of Head Pressure
Bosch #10 manual states: 3.7 GPM (1400 dm3 / 0,3 bar)
Awfully close to what I stated straight from the mfg mouths!
Many drag/racers/sl55/s600 boys opt for the Meziere WP136S rating at 20 GPM.
