what to expect from HP upgrades
 
Not givin any details out on the new motors but wondering what i can expect to see out of my setup with 560hp 550tq w/b1's (unsure of what prop ill need to run just yet)

93 dominator with 330's in there now..

Anyone have any experience?

I have a friend with an older 32 500hp and he hits 80gps on a good day...my guess with an honest 550hp at the crank and the right props 83-85 is realistic.

I would make sure to upgrade your drives too otherwise you might have a lot of downtime with B1's.

Agree. XR's at a minimum.

You need Hyd steering,it is a must over 70. Also Drive showers, and see about beefing up the drives. Contact Dominator Scott he can give you all the tricks to do on that hull. If he is not here he is on Sunsation's website and speedwake also. Depending how high you want to spin the motors you will also need props. You have 3 blade (unless someone changed them from wheh I had your boat) now I would think you will want 4 blades at least. You could also contact Joe or Wayne they may have other idels also.

somewhere around 12mph gain. 28 to 30 bravo 4 blade nonlab depending on rpm would be my guess. what prop are you running now? how fast are you running now, high 60s?

yup. 68-69 any day 70.4 best ever (on fumes and just me in the boat).. ya, i usually pick scotts brain anytime i have any questions.. I think ill be ok with my bravos for awhile. they were just rebuilt before i got the boat.. that, and im pretty comfortable behind the sticks and babyin it.. XR's are definately out of the budget for a while. However, hydraulic steering sounds like a good idea!

You'll be fine with bravos and that HP. having twins to share the load pushing the boat helps alot.
