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!:cool:) 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...:drink:

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.
