bill
you hit the nail head dead on,,,,
here we race the tri hull class,,,100ci crossflow only
the best motor is the omc for the class

and these guys have tried everything,,,,,,,,,,,
the 1s that are staying running and winning are just hitting up on the normal items and better parts and clean work

as i stated and others just deburing intake tracks,,,and leaving as much metal as possible and epoxy filling where you can increases the crankcase pressure,,,,better running,,,
i call it D porting ,,,leaving the sides and bottoms alone,,,,on the ports
cutting out the bridge is even more flow at same timing,,,,a big factor
gives the motor dock and turning power,,,,

hey bill
what would be cool is for you to do your guru stuff on a crossflow motor,,,,
send it down here,,,,,,,
ill put it on a boat,,,,you come down and drive it
1st race at highlands is a 1 day event,,and i have a motor home for you to stay in at the track
if it runs anything like the 2.5 you did for chris in kankakee,,,,,look out tri hullers
