Re: [DML] Carburetors suck.

[Cecil Longwisch <dmc8182@xxxxxxxxx>]

Again you did not answer my question, "has anyone had this on a dyno"? Seat
of the pants is not a scientific judgement.
I am more familar with the horsepower output of corvettes as they offered
in vintage years several carb configurations and always (yes always) the
fuel injected offered the highest horsepower output out of the same engine.
Even multiple carbs produced less horsepower.

Unless there is some magic here you will sacrifice horsepower.
Show the forum the data.
