15 Mph Gain 38 Cigarette T/s Top Gun
WE GAINED 15 MPH WITH THE ADDICTION OF VORTECH SUPERCHARGERS. BOAT HAD MERC 500EFI'S WITH STOCK BRAVO DRIVES. INSTALLED THE VOTECHS AND UPGRADED THE DRIVE TO IMCO XTREME ADVANTAGE DRIVES WITH 1 INCH SPACERS. GAINED 15MPH AT WOT (83-98) GAINED 10MPH AT 4000 AND THE BOAT IS A HOT ROD TO DRIVE.
NOTE -- WHEN WE INSTALLED THE IMCO DRIVE THEY HAVE A BIGGER WATER INTAKE ON THE NOSE CONE, WHICH ALLOWS MORE WATER PSI. THAT WAS A BIG PROBLEM WE HAD 40PSI ++ ON THE GAUGE. HAD TO INSTALL GRIMES WATER DUMPS TO FIX PROBLEM. HAS ANYONE ELSE HAD THIS PROBLEM WITH THE IMCO DRIVE

Alright!! Thats it, I'm buying some blowers!!! Screw this 82 mph crap........98 mph sounds just about right. What mods did you have to do to the EFI's??? Do you have any pics? What did it end up costing and is it a bolt on kit or does it require tweeking??

Were they standard length drives before the spacers? So now they are 1" lower than stock? Or were they 2" shorties reduced to 1"?
