SB Speeds @ hp

krakmeup · 02-17-2009, 08:19 AM

I'm considering new power, what horsepower and WOT speed are you seeing on the SB Y2K?
e.g. :
496 MagHO 2005 Hull 72-74mph @ 425 HP

525 HP = ?mph (seen posts of ~82-3 actual with 87 max)
700 HP = ?mph
850 HP = ?mph

At what HP will my "older" hull reach 100mph? (and what are the modifications to today's "newer" hull?)

Thanks!

Keith

keith, glad your keeping the Y2K, and bumping up the HP. My hull, ( same bottom as yours ) was seeing 83-84 with the Merc 600sci. With the Potter 800efi/NA we hit as low as 89, up to 92 ( still playing with props ). I think with the older bottoms somewere around 900 hp will hit the 100mph mark.As for the newer stepped bottom Y2K, speeds will be up, how much, not enough data out there to compare. But in the rough the newer bottom really won't matter. Keith you are seeing 72-74 now, if you get your hull to the upper 80's your going to love the ride. ( in a 2' close chop ) WOW !!!! What brand motor are you looking at ???

Thanks Gary, this is great info.....

I'm all over the place right now.

Options include, listed in oder of suspected cost:
- beefing the 496 + whipple
- build a 540, maybe EFI, locally and then whipple later??
- Merc 700
- Ilmore V-10, Teague or other well known builder

So many choices.......so little time. I may have to wait until after this season, but we'll see

We'll build ya a nice motor Keith

No doubt, ff2, but I'm probably going to stay local unless I pick a manufactured package. Delivery and support to the Texas Gulf Coast area probably is a bit much to ask, unless you get real good frequent flyer perks

hey k...
glad the boat's treating you well since it left the tri-state area...funny how great just isn't enough, eh?

fast...i'm not sure, but i dont think a blown 540 will fit in the overhead bin OR under the seat in front of you!

I had the pleasure of buying a 609CI motor from Ron Potter this winter. I was extremely impressed with everything. He is a really detail oriented guy and truly cares about the customer. He is also very highly respected in the marine engine business (all the way up to NY area)
