crankcase is stuffed like the thanksgiving turkey, lol! you can never have enough power, so a lil more torque never hurts. i'm not running a bleed system, this engine was patterned after the 2.5/260/280 and they don't run a bleed system, alot of it has to do w/ where the fuel is injected, and this thing doesn't have any fuel going thru the reeds, so there shouldn't be any puddling issues w/ fuel. they typically use the bleed system to help improve the idle by getting rid of pudled fuel in the intake tract.
