Hi John, the machine was a standard pro 400 custom using the enforcer sd/hd setup.
I then mounted in parallel to give me an AO configuration. Albeit Un matched motors- perhaps upgrading to two hd electros should have been first port of call.
I was enquiring about matt adapting it to a twin cord 2x6.6 or even the 1850w electros as they seem to have better lift with a little less airflow then the 6.6, as the booster came upon offer at 299+vat it was a much cheaper option.
Ran it today between jobs with 100' 2" and the wand was whistling at least the same if not more then it did at 50' with 2vacs. Also the lift is achieved very quickly compared to the twin vac. I believe the motors would produce around 350cfm with 130" lift, but obviously there is restrictions on the system itself, such as the 1" orifice where the ball cage is
In summary- so far so good
