280 with 630hp speed
 

Can anyone tell me how fast a 280 would be with 630hp?

Just doing some winter dreaming.

Thanks

I would estimate 82-84 GPS

I have a friend with a older 26, that he says is around 600-625 Hp. He says it runs 90. But I have never seen it :blahblah:

I would agree more with Revd up

I seen a video with Kenny that the 290 with a 525 should do 85. I thought/hoped it would be closer to 90 but I'm only in the dreaming stages now lol.

My concern is that damn bravo drive. Has any one got an arneson drive to work on a smaller Velocity?

Put a imco on it. You will be much happier

Agree on the 82 - 84 MPH. The 290/VR-1 hull is faster no question. If you throttle it properly you should be just fine running a Bravo with 625 HP on a 280. My 280 has 615 HP and reliably ran a STANDARD Bravo X for many years. Bravo XR's are rated for 600 HP and the Velocities are more Bravo drive friendly then step hulls so I'd go that way first. If you're still concerned I'd look into the Bravo Drive Guardian system which Saris Racing has used very successfully for a couple of OPA racing seasons. There's no Velocity single arneson set-ups that I'm aware and probably for good reason. Besides being a very expensive proposition for likely a 10 year old plus 280, the performance outcome is uncertain and there are other practical drawbacks as well.

Thanks for the info everyone.

How is the 29 different than the 280? I'm talking about the weekender, not the vr. I always thought they were very close.

I agree with Revd Up, I've got 798hp , has run honest 96 couple times on gps and gps speedo, but will run 93 anytime with bravo. Any faster would need imco lower or more power it would need imco upper.

It should run 90 to 95

The 28 is a 26 with a swim platform. I think the 29 is a bit different. I believe the VR is a stripped down version, makes it lighter. I'm sure someone will chime in on the VR29

As I understand it, the VR1 and the VR29 weekender share the same Hull profiles with the top deck moulding raised for the weekender to allow more headroom in the cabin. This will probably add a little weight penalty over the VR1.

Correct. The VR1 comes in at 4300lbs. 290SC roughly 400 lbs heavier. Both 22* deadrise, conventional lifting strakes with a 3" high notched transom. 1' wide pad. Pad is offset 6.5" to port of keel and 5.5" to starboard to offset the right hand turning prop. It is a very fast hull. Mine runs 73-75 with 425hp.

Thanks for all the info.

FWIW I like Kenny's mph. :)

I had a 1998 260 26' with 720 HP and B-Max drive and it would run right at 94.8 GPS

I have a 280 with a stock 502 and a whipple, bravo drive and a labed 29. It has run 78 gps full of fuel and coolers. I just got it but I really think it will run 82-83 in the right conditions.
