Does anyone know whats the fastest and safest speed on a 29 world class is. Im building a 29 world class mid cuddy with a 850 horse 572. Any ides how fast.

The mid cuddys are heavier boats. So I would say with a real 850 you should see 90. That would be all other thing being right ie shorty and big prop.
A full race boat like mine with real big power has run 110 but I heard it was a crazy ride and boat was all over the place. I think big Scotty tried setting the kilo record in it. Wasn't fun.

If you dont mind me asking what are you running, and what kind of drive, imjust asking so i can get some ideas

572 all billet. Well not the block lol. About 750 I can hit 90/91.
I run a x drive with a 2in shorty. My boat is a f1 build so pretty light. Blue printed bottom etc.

Mine ran 88 with stock 500 efi. It was a race boat built light. I believe it weighed around 4000 lbs ready to race.

Thanks for all the post. I was just going to sell mine and get something different but after doing research on WARLOCK I think im just going to fix mine up, Its pretty nice as it is now but i just want to update some things.Im going to post some pics as i schange things. Im bout to buy a scoop for the hatch so the blower will fit i havent measured the new blown 572 yet, but any idea how big of a scoop i might need. I was just going to go with the hardin marine low pro one.

That's pretty amazing every 29wc race boat I have seen would only run about 75/77 with that set up. mines a little heavier now since I added rear bolsters and a big stereo.

There was one in MD a few years back running a big 700 cubic inch motor in it. It was sick fast. I think is some info on the boat posted here way back.

Mine was an EFI and light. I would spin a 30 pitch bravo 1 on the limiter. The boat won the world championship in key west in 99. Spanked everything there. Second place was over a min behind. I wish I could find it. A pro hockey player who was retired bought it. He lived in Maryland.
