Not to turn this into an ice-out thread, but it seems pretty clear from the recent weather that the lake will easily be open and ready by then.

For us with foolish imaginations!!!Here's a link of the Cat. C32's underway at full throttle. I almost fell outta' my chair laughing with images of a planed out 'Mount in the broards headed for Alton.

Once Winnfabs get a hold of this video, The Mt will be outlawed forever!

GREAT VIDEO , yup that'll leave one heck of a wake.

[OCDACTIVE]

Very nice! Beautiful engines. Given those were Jet Drives in that video on a Cat boat but definately a lot of power....

Those must be the 1600 HP variants. They trade HP for longevity.

Speaking of variants, I was looking at the Caterpillar engine brochure upthread http://marine.cat.com/cda/files/9627...ngine.pdf?mode and see that they go from 660 hp all the way to 1300 hp, holding RPMs constant at 1800, then up to 1600 hp @ 2300 RPM. This, all on the same displacement, with twin turbochargers?

Either the engines at the lower end, such as the 660s or the 750s in the Mount are going to last forever, or the 1600 hp units are really being pushed hard.

Question to those with experience with larger diesels such as these: Would the lubrication systems, internal parts such as pistons etc. be the same, or would things like the alloys used for identical-looking parts be different? Is the main difference simply in the injectors, turbo dump gates, and engine controls, plus a beefed up component list better able to take the heat and pressure or is it simply all done via engine controls and injection and turbo settings?

The Enterprise units did about 615 hp on something like 7 times the displacement of these new engines, though the former didn't have turbos I gather. That comparison, plus the differences in the C32 family itself, make for quite a range of power per unit displacement variations!

[Dave R]

I'm pretty sure that above a certain HP range, CAT puts 4 turbos on the C32.

My gut says they'd have to modify the cooling and oiling systems on the high HP engines, just to keep them cool. You can't run a 1900 HP cooling system on a 600 HP engine or it'll never get to the corrrect operating temperature and that hurts longevity more than higher turbo pressure or RPM. I think it would be safe to assume they'd use different pistons and valves in the high HP variants, and you can be sure the fuel system is different. I bet the rods, crank and block are the same.

The Electronic Control Module (ECM) is the "brain" or center of the C32 ACERTengine control system.

The ECM uses the information
gathered by the sensors
which are located throughout
the engine and transmission
to monitor all aspects of
engine operation.
Connected to the ECM by the
wiring harness, the sensors
detect and convert changes in
pressure, temperature or
mechanical movement into
electrical signals. The electrical
signals are sent to the ECM.
The ECM uses information such
as desired engine speed, and
load to determine the fuel
injection pressure, timing and
duration. Based on sensor
inputs, the ECM actuates the
individual unit injectors to
control engine speed.
The customer connector allows
the engine’s ECM to interface
with Caterpillar monitoring
systems or other manufacturer’s
monitoring systems. These
systems display engineoperating
parameters such as
speed, load, fuel consumption,
temperature, pressure,
maintenance and diagnostic
information, as well as trip
and historical data. Additional
switches, lamps, and optional
components can be installed
and linked to the customer
connector.
The service technician
communicates with the ECM by
means of computer, cable, and
service tool connector, to
perform diagnostic tests and

modify operating parameters.

I know she's an old girl, but wouldn't it have been great to go with the twin turbos! Maybe a little propane injection to quickly get up on plane, and yank the props for a couple of jet drives...

OR, how about a couple of Arneson surface-piercing drives?? I wonder if they make a drive big enough for the Mount's needs?

The ASD 15 will handle a 2200 HP diesel engine. The ASD 16 and ASD 18 will handle lots more than that. I don't think the mount would ever do much better than 20.25 knots, regardless of power though.
