What is the maximum power that someone has acheived with a single GRA carb on a I6 turbo motor before it has run out of flow? Also What would be the advantage of running twin carbs on a I6 turbo if there is any advantage?

I know. Theres an XE ESP turbo with a 480CFM carb making 550 rw HP. I think that is the biggest carb in the range and I'm wondering how much more flow can that carb support before another is needed?

So GRA would recomend 2 smaller carbs then? Come to think about it, that may make the car more drivable under boost and maybe the 2 smaller carbs could out flow the big single up top. It would be a b**ch to setup though.
