Your top speed is kind of strange. I was reading a Hot Boats test (Feb. 2001 issue)article recently where a 28' Howard Bullet V that went 74 mph. In another mag , an Eliminator 25' V went 80 with a 500hp. I would have thought a tunnel would be much more efficient than the V hulls when compared with the same power. At any rate, If your looking for more speed , put a procharger or any of the other aftermarket blowers.I have heard of people getting 5-10 mph from this mod.I would think it would be in the $5000 range for this upgrade. Much less than the new motor your looking at not counting the labor cost involed.
