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??

You really need to find another 2 mph...
98mph is rockin! But if I was that close I would need to see 100. |

I KNOW 98 IS NICE BUT LIFE BEGINS AT 100. BUT THE OWNER OF THE BOAT IS HAPPY FOR NOW WITH 98. AS FOR COST WITH THE DRIVE UPGRADE $45,000. THE VORTECH KITS COST AROUND $7,000 A PIECE.

Just a few more pounds of boost!

Yes the drives were 2 inch shorter drives. We ran a 36 Gladiator the week before withe the 2 inch shorter IMCO drives and we lost 4 mph. So we knew we needed the spacer for the 38. |
