It would be cheaper to port the -1's


Chris..

Do you think they will make 50 to 100 more HP then what they are making now ?




Not sure about hp numbers, but I think that a ported -1 would out flow an ootb 572-13..

Check these ported numbers.. The 572-13 barely out flows the -1's both ported..

Check Modern and Porter to compare.. I believe they're both about 375 @ .700 lift..

Like I said, I would just port the -1's.. On a 572" with stock 440-1's, you are giving up quite a bit of power. So 50-100hp I would guess is possible.
