Ill know in a couple weeks. When it comes out and go on the dyno b4 I tear it down...

Sorry donzi 27 zx. N/a 632. I'm guessing 850. Previous owner said 93 with an 850 blower motor but said water had to be perfect cause of the ill handling. Not been my experience. She loves rough water. But the again I went from a 24 with 900hp and no trim tabs. So, I'll handling to me might be a little different than most...

I have a VR-1 Velocity 29' I broke triple digits this year , your going to need 800 + hp most likely

A 29 with a 525 will hit an honest 75. Some say faster but 75 for sure. Needing about a 20 hp increase to add 1 m.p.h. you can do the math from there. Seems like it would take 1000 h.p. or so.
I have a 29 Fever. I can imagine going 80 - 85 on flat water. 100+ I would run out of bal@s! Good luck and have a good life jacket on.

I've been told by a few guys with Fountains they straighten out once you get over 90.

that boat will be a hand full in the 80's for sure, not sure about the higher numbers. a friend is running almost 900 hp in his 27 and it runs 84, shorty drive too. you will need all of 1000 hp to go over 100 mph. you will hear a lot of inflated speed numbers on the forums, real numbers are hard to come by lol.. it's not only the hp but the right driver can make all the difference in the world with a good pass. be safe, that boat can get squirlly, some boats make you "drive" them

Sounds awfully slow for 900. Does he know that the anchor needs to be pulled up while running?
