I'm not going to run any carbs, its fuel injected. Individual TBs should have better driveability than single large throttle body. Same goes with fuel injection. Max power probably isn't any better than with carb, but i bet mileage, driveability, midrange etc are better. It's not going to be a race car, more like weekend cruiser that can beat bigblocks. And I like to think out of the box :) This one is made more like european turbo builds here. There was a 2,6 litre Volvo build with pretty same specs and they dynoed 560hp/660nm. We'll see what this little larger slant can do :D
