Strip- the PB Mag article mentions the torque curve - at 3,000 rpm it makes 500 ft pounds of tq- it also says "with electronic variable cam timing, we can build a torque curve that's almost like a diesel engine, but with a much wider rpm range.

Strange thing about that boat - I wonder if it actually exists. If you look at the pictures on that site, every pic appears to be a different boat - Paint scheme doesn't match in any of the 2 pictures...

Maybe 'if you buy it, they will build it'...

Mercury's (Noah's?) formula for speed is:

Hull efficiency (Assume 250 for a late model V-hull)
______________________ (divided by)

Square root of:

total weight
________________________
HP

As a base line, an 8500 vee hull with fuel and 2 passengers with twin 525 EFI (really 540HP ea +/-) with a "250" hull efficiency = 89.1 MPH (hull efficiency is a constant)

The same twin engine "Rayar powered" boat (assumes right balance) with same 1080 HP but 1000 lbs less (7500 lbs) total weight = 94.9 MPH

Maybe Raylar just needs a better marketing program...

nice, where is raylar located?

Yes, that is what I suspect as well. I would love to open one of the performance magazines and see a detailed write-up on that very combination (and I'm sure you would too!) I would think if Raylar provided a sweet deal to one of the big Formula dealers, and the combintation lives up to the performance we anticipate, that would really create more interest and drive new business.

I have been talking about these motors on here in a couple different threads...they are awesome!!
If Raylar wanted some excellent exposure they would rig my 28 Active Thunder with twins and some Imco drives and I could demo for as many customers as they wanted!!
That would be a perfect application for those 550's!

pretty good TQ for a sb,so it would be close to a big block

Now that would be a nice package and should really fly! What does a 28 AT weigh in at? A 292 is heavy at 7500 lbs dry, although it does have twin steps...

You're in the perfect situation! oink oink lol

Unless they're making them entirely from depleted uranium, those numbers are way high. A pan-to-carb BBC weighs about 600 lbs.

Those numbers have to be drives, gimbals, and a fully-dressed engine, from exhaust manifolds to coolers, pumps, alternator, etc.
