Not saying it aint for all just aint for most is all My carb is a good deal bigger CFM wise but with a more favorable blade booster sizing. Looking like my pair for the Predator will flow more cfm than 1250 as well.

IMO if it picked up that much over the 1150 it likely needed some more work, would be my opinion anytime an OOTB carb picks up from a previous carb of that size that was dialed in unless it was simply the worng carb to begin with. A tenth and 3.5MPH is a TON. Just sayin.
