Some unsolicited musings.......
I’m not a fan of what Charles did with the square manifold opening.
In my mind, that’s now going to pretty much require some sort of adapter to smoothly transition from the carb throttle bores to that square shape.
Which may not be the hot ticket for keeping the fuel suspended in the air stream as it exits the throttle bores.
I guess time will tell.
As for the loss of flow on the bench with the divider cut down.......
You’re only flowing one side of the manifold, and you took away the radius entry for 25% of the opening for the side your testing. Like if he was testing it before the divider was cut down, and then removed the clay that was on top of the divider.
You’d expect the flow to go down as a result.
It’s a situation where the flow bench is not accurately replicating what’s going on with the running angine....... and that can steer you in the wrong direction.
Imo........Cutting the divider down is not about the “flow”, it’s about giving both sides of the manifold access to both sides of the way under sized carb.
I also feel that at this point, since the squaring of the carb pad has already been done, if that’s in fact the manifold they intend to use......the carb adapter situation should be dealt with sooner rather than later........ and some tests with a carb should be moved up on the testing schedule(if you’re chasing flow).
