Pressurise the float bowl, and raise your fuel pressure on a 1:1 ratio to your boost.

At an idle fuel pressure of 4 psi, you will need 9 psi of fuel pressure to the carb at 5 psi of boost.

It's either that, or you suck through the 750, into each of the twin turbos---which isn't hard to replumb either.

V8 forum?
