pretty much dead on the same ..... both are GPS ...... they both dynode @ over 840 each ..... Bob Madara's numbers called for ez 900hp but the dyno we used has a history of being 8-10% short on the numbers ... meaning his motors are usually stronger than other motors that showed bigger numbers somewhere else .... Bobs usually pretty conservative on his numbers and pretty much always right ..Cant ask for a more knowledgeable or Friendly guy ......m

Key is "Proper Setup" ..... deep drives, stock 32's and over 10K lbs .... I'm happy .... Using the Bam Calculator 1800hp with High Drives, boxes, notched transom, good bottom .... calculates 104mph .... Also shows 20% Slip .... (101) .... But at this point Slip is my Friend (drives) ......m
