boxes and more prop with 1" shortys will help ya, my buddy (Lake Effect) 98' 353 Formula has 509's 7 lbs boost, 1" shortys with 36 labbed 4 blades best of 107@6000 now with safer tune easily went 103 with a loose bonnet down 2 lbs boost, prochargers are bad azz.....


he can give ya advice if needed... smart dude

awesome!!!!!

Wonder how long stock 502's would last with prochargers

impressive how accurate is your regular speedo compared to your GPS !!! How many HP does that engine recipe gives you?

congrats

Congratulations Mike..

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

well, They were on these 502's from 2000-2011.... First cpl of years only issues were head Gaskets and drives .... He O'ringed the heads and went to Imco Drives .... after that ran 8-9 years with no issues ....m

if you are making that much HP, I am gonna say with proper setup that would be easily 108 mph boat.....

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
