and before allt eh 25o/l owners jump on my case, i disnt say it isnt possible for one to run 72 on gps with a 425.. i know it is possible and i also know it has been discussed here many times. im just saying it seems the average is more like 68-70.

Should be faster... Tell your customer to drop the sink, stove, microwave and tv...

There is absolutley no reason (IMO) a true 640HP isn't pushing that rig near to 80.

he may be running even less boost most of the time to be honest with you, just going off what i have been told. i know he runs a labbed 28 most of the time with his wife and 2 kids on board. it is possible that with a prop change it coud run 80.

my brothers 2002 25 outlaw with a 496 ho ran 64.7 before labbing the prop and 66.7 after.

Need to be careful to really evaluate the horsepower on 496"s with superchargers. Remember the supercharger itself uses 50-75 horsepower at full boost to make its power. Some manufacturers are overstating horsepower at the crank. If you have 650HP advertised less 50-75HP for a 575HP net then the speeds expected will have to be based on this "real" number. Just a thought for your planning.

I highly doubt a 25 o.l. w/ H.O. will hit the low 70's,, maybe on fumes in cold air temp, cold water, running down river w/ a tail wind..

maybe on the trailer

I take offence to your comments. I owned a 25 Outlaw and no longer do, so what do you think my motivation would be to lie? I have a tight friend that owns, still, a 2003 Fountain 27 fever with an HO. No matter the condition I could creep away from him.

If you have owned a 25 Outlaw I take back my comments. I have never owned an "open bow" 28' (including swim platform) Sunsation, so you will never hear me comment on the speed, performance, etc. that it lacks.

Im just curious. I believe you but I wonder why my brother cant break 67 with a labbed prop by bblades? It wouldnt break 65 with a stock prop. I cant figure out why it would be slower?? I told him it was cuz he couldnt drive

Neil,, I fail to see where I quoted your post ?? I certainly didn't insinuate you were a liar. The speeds of 25 O.L.'s w/ H.O. has been beaten to death over the years, thats what I was referring to. I personally know 2 people w/ 25 outlaws, w/ H.O.'s and they see 65-66 with half fuel and 2 people.. Fumes in the spring or fall they may see 68-69.. low 70's,, fine,, if thats what you say... Owned, driven, Been around, and demo'ed enough Baja's to know their speeds.. I don't own an " open bow " Sunsation 288...
