Yes Shaun i could do that ... i kid a bit about getting ever thing from B&Q , the connections etc came from ebay mostly ... buy nothing really difficult , you would need a holesaw a few bit also .
Yes i have tested it ... i have not got figures but there is extreme violence at the hose cuff
The two vacs inside the Enforcer on their own measure18HG ( about 244" lift ) cfm would be around 130 ...
With the booster plugged in the airflow is noticeably better , should be around 250+ and 17HG
I did get a cheap CFM anemometer but it lacks an accurate calibration ... i do have a lift gauge .
The tank does not flex because of the design and the plastic is 10mm thick .
That was one of my biggest concerns .... drilling a hole in the waste tank without knowing the structural implications . Once you drill there is no going back .... but its all good .. I did intend to do connect the booster port internally , but when i saw the internal design , to get a custom manifold made and relocate the motor was a hassle against just rilling an external hole .
Yes i have screw cap that fits in seconds to block the port hole .
