Ok this is what I'm going to end up doing:
-new internals to handle the supercharger
-a Whipple
-if I still have money left, a Raylar kit.
Sounds awesome.

Good Luck and let us know how the build goes.

You know what saturday is??? Donzi time!

Yea man! Can't wait to get it in. Maybe, just maybe, I'll let you drive it for a little.

bro you have a little donzi...

It's an awesome little donzi!!

I don't think I'll need to supercharge it, it's crazy fast as it is for a 22'. 80mph! I'll porbably just go with some forged internals and a basic raylar kit. Only thing I'd like is faster acceleration.

After a lot of boat driving, I'll admit that I was wrong. I had maximum throttle going and the boat handled any bumps perfectly fine. "That bump" I was talking about for high speeds is no longer something I'm worried about, so now that it's not an issue, here are some upgrades for boat performance I was looking into.

For the boat's performance as a whole, I am going to get the following items:
-Mercury K-Planes
-If I have room to mount it, my friend offered me his old Mercury VesselView
-Raylar 103 BigPower Engine Kit
Engine kit consists of:
• BigPower aluminum cylinder heads (pair)
• BP 103 High Performance camshaft designed to work with 496-8.1 engines fitted with stock pistons. Marine and HiPo
• R-INTK "CoolGap" intake manifold
• R170SS1-1.7 ratio SS roller rockers with nuts
• R-ARP1 re-torqueable high strength head bolts
• RCM-SS1 Cometic special MLS head gasket set
That should give me 525+HP.

Or, if not the 103, then the 106.
The 106 is:
• BigPower aluminum cylinder heads (pair)
• BP 106 High lift / big duration camshaft ***(must only be used with forged aftermarket pistons with deep valve relief)
• R-INTK "CoolGap" intake manifold
• R170SS1-1.7 ratio SS roller rockers with nuts
• R-ARP1 re-torqueable high strength head bolts
• RCM-SS1 Cometic special MLS head gasket set
• New Billet Throttle Body
• Reprogram on your ECM
That would give me 550+HP.

Decisions, decisions...

Go with the BCK-106 with forged internals and headers....mine just dyno'd at 660HP @ 5400 RPM and still making power!!
