torque CURVE is what is important, not just plain torque. Torque is what all motors produce. Some more, some less, some at higher revs, some at lower revs, some have flat curves, some have peaky curves. A marine motor is a pure loading environment. No gears to run thru, no manual clutch to control the slip, no custom torque converter to let it get the revs up. Marine motors require a pretty flat torque curve else you never get the boat to plane with any authority.Originally Posted by kickin32
Can a Viper motor make big numbers? Sure.
But sustained extreme loading at high revs is the norm in a marine application. I've already been told by a reputable source that the V10 crankshaft and bearing sizes are not a good choice for a big blower pulley on the snout. High revs, a fairly long crankshaft and the harmonics that go along with it give you a situation where adding a 70 horsepower torsion load and a 300 pound vertical thrust load on the snout of the crank (from the blower drive) is creating a situation that might not be a great idea.
Turbo marine motors are a little more esoteric and out of the mainstream than blower motors, but would indeed be an option.
Back to the discussion here, the current state of the V10 development cycle gives you a platform that will yield around 800 horses before you get into some territory that causes you some financial pain.
5 years may be a different story.
We've had since the early 60's to develop the BBC.
So, yeah, go ahead and put a couple of fat cammed blown 1200 horse V10's in a Cig Tiger and turn it loose for a couple of hard running days. I'm as interested in the next guy to see what breaks first.
All this talking is making me hungry to see some broken crank snouts and holes in oil pans. Nothing like a 40 pound balancer and blower pulley ricocheting around the bilge at 5500 rpm.
