Many years ago I had an original Mini (before BMW bought them) fitted with a FISH carb in place of the standard SU.
According to the seller this was the ultimate in racing gear and know to a "select few" as "the winning edge" !
Great stuff but a real shame it didn't do as promised!
Easy to set up and virtually no parts inside either. Kind of like a lawnmower carb in a lot of ways. Basic and simple.
Fuel economy was about the same as the SU's , power was lower and torque was lower (I had the car dyno tested since at the time I was part owner in an operation which had access to one) and that was about it.
One flaw was it was either set up for a limited speed range (flow) so any other speed range it didn't perform as well as the original SU.
A "miracle" it was not and "super efficient" was something to dream about.
Eventually I sold it to someone who saw it on the bench and wanted to buy it despite my warnings.
Got what I paid for it so I was happy and I reverted to the standard SU.
As an aside David Vizard gives them a review in some of his books if that is a help.
