Blow through on BBD carb?

I tried both the BBD and a 2280....the BBD seems to handle boost better initially but has a brass float that will crush under boost pressure.
The 2280 seems to be better as far as tuning is concerned, HOWEVER, you need to understand the hanger 18 mods and how to accomplish the same things with the 2280. I butchered mine beyond repair before I was able to make sense of what was going on. I had too many variables that I was working on and didn't understand exactly how they corresponded to each other... :(
I have no idea how to setup the BBD for boost...
What I did learn about the 2280 is that there are 2 enrichment circuits ( mech and vac ) and it is possible to richen it up by "turning" the enrichment pins ( like shaving them down, not screw "turning" ) to have them come in sooner and making the passages underneath them larger to deliver more fuel.
A little goes a loooong way.... I hosed mine up and was so rich it would almost stall...no good.
If you don't care about ruining the 2280 or spending months tinkering, then try it, otherwise pick up a 2300.
Plenty of advice and articles about tuning it.

On my slant, I'm using the 2300 with the stock jets, pink accelerator pump cam, vent tube extensions and it runs well at 6psi...except for the heat soak because I don't have the intercooler installed yet ( and I'm starting to lean it back to regain some of the fuel mileage...
