Clifford,
I was given to understand that a CV style carb did not require the same hassles as a normal-style with regards to the "pressurized box". I understand what happens if you try and blow-through a normal carb, it pressurizes the bowl and blows fuel everywhere. OR, since this is gonna be one carb it would be possible to modify the 4-1 turbo intake to actually enclose a single sporty CV carb, which eliminates pretty much all hassles. I could even tune that one NA, slap the turbo on and run 'er.

I might be interested in the seca carbs as well. There's a guy on the SOHC board who's working up a blow-through setup off a set of CB650 carbs right now too.
