Food for thought since you like the mag tests so much......POWERBOAT tested a 28 with a 496HO in CA at sea level in salt water and got 70.9 MPH. What is your elevation in Salt Lake City ?

Sorry LIOPA, don’t mean to sound negative; Just friendly conversing
I know personally what hp it takes to run anywhere remotely near 90 at Havasu and it won’t be found in a naturally aspirated Ilmor. I also know Lonnie
Great run on the 496HO at sea level and on salt. Neither Steve (INDY) nor others have been able to duplicate it nor will a mere100 hp add 10 mph to that impressive number.
We live at 4500 feet and boat between 4500-6200 feet. Your customers Heat would do good to approach 70 in these parts. It’s quite a humbling experience when boaters come here. Note though, all the test I have listed in this and other threads do not include any high altitude numbers for obvious reasons.
Also, I’m not totally unfamiliar with saltwater…see below

Understood Dave,
All I can say and post is what these guys are getting on GPS.
....and yes have seen it on board myself.
I am truly surprised others have seen such low numbers.
The offer is always open for anyone to come out for a ride if you visit this area. We are trying a new prop on that 28/525 boat this weekend. I'll let you know what happens.

NICE 25 BTW....what was in it?

Hey Dave,
The 525 BTW is very under rated by Mercury Racing. They DYNO higher out of the box than the stated 525 HP....more like 540-545. The 496 HO is on the money at 425 HP...so the gain is closer to 120 HP. On the Nordic, Ultra, and Velocity 28's 12-13 HP = 1 MPH in these parts. Which makes more sense on the speeds being seen here.
