Gas engine and Diesel of same specs.Pull the same.

lol this threads funny.

Caterpillar Develops Industry-Leading Supercharged Diesel Engine
Cat® C12.9 to Deliver Superb Performance in Compact Package

With the specter of increased fuel prices and stringent emissions regulations on the horizon, Caterpillar has joined forces with Fiat Powertrain Technologies (FPT Industrial, S.p.A.) to deliver a solution for its pleasure craft customers seeking a high performance, fuel efficient marine diesel engine – the Cat® C12.9. Expected to be available in 2014, the C12.9 will be available in both 850 mhp @ 2300 rpm and 1000 mhp @ 2300 rpm iterations, with the latter making the C12.9 an industry leader in power density.

The new power plant utilizes innovative fuel and air management techniques to comply with United States EPA Tier 3, IMO II, and CCNR Stage II emission regulations while offering incredible performance at the simple touch of the throttle or joystick.

Bob Hallengren, product director for Caterpillar Marine Power Systems, stated, “The C12.9 provides our customers with industry-leading engine performance characteristics for power density and vessel performance while meeting all present and future environmental regulations. Most importantly, this outstanding product is backed by the global Cat dealer network.”

While owners may opt for conventional Cat controls, the design of the C12.9 is conducive to the seamless integration of the newly-announced Cat pod drives. Furthermore, they may prefer the installation of the Cat proprietary Three60 Precision Control featuring joystick maneuverability. With the installation of this trifecta of power, propulsion, and control, the vessel’s operator is afforded an unparalleled level of low-end torque and maneuverability.

In its turbocharged variant, the new C12.9 offers a commendable 850 mhp made possible by FPT Industrial’s advancements in second-generation common rail technology as well as an expertly designed air management system; the engine’s small envelope and high power output make it the ideal choice for the discerning yachtsman who seeks performance in a compact

Discerning yachtsman.

:C

Pass the Grey Poupon.

Here's a 1000 hp engine that will run for 10's of thousands of hours. Look at the torque this motor has also.

lol 800 hp gas motor will likely be torn down after running prolonged periods. even a built diesel motor pushin 1000 hp will likely only see so much run time at that level before needing a tear down.

That is a boat motor and it is capable of turning WAAAY more than 5500 rpm's. It is governed at that for many reasons, warranty is one of them.

Even detuned, let's see if it will hold up for 15,000 hours.;)

At what rpm do the valves begin to float and the engine start to self destruct? Facts, not opinion. And why only 15,000 hours? Why not 60,000 hours?

There are gas motors that turn in the 9-11,000 range all the time and that's just 800 hp engines. I would think a motor with that hp should turn 10,000 easy.

Show me a gasoline engine with 60,000 hrs on it. That would be like 2,000,000 miles.

Since we are talking about turbo gassers now how about a 9.0 liter turbo gas v8. How about 1325 ft lb at 2300 rpm, then it revs out to 1350 hp at 5500 rpm. This engine also comes with a factory warranty and is made to run full throttle for long periods of time.



Turbo gasser

Diesel is chosen for fuel mileage not for power. It has big low rpm torque because of the turbo. A non turbo diesel is a turd. A turbo gas engine makes just as much torque as a diesel.

Do a little tuning on the diesel and then there is no comparison,none, notta. And yes it will hold up to it with no problems.

Not quite. I have an Audi with a 2 liter turbo direct injection gas engine. Stock it puts out 211 hp and 258 lb torque. The peak torque is between 1500 and 4200 rpm. To match that torque and hp per liter displacement, the latest DM, PS or Cummins would need to put out over 700 HP and 860 lb torque. I can go to an Audi dealer and get a Stassis ECM program and exhaust with full factory backed warranty and boost the output to 270 hp and 328 lb torque. To match that output per liter the diesels would need to produce 900 hp and 1100 lb torque.

Yes, I completely agree diesels make for better towing and I love my Cummins but today's gassers aren't your grandpa's gassers.

well you dont have a typical gas motor, you have a turbo motor. little different than the motors in the trucks people tow with. basicall you can just up the boost n fuel til she pops. not so easy on natural aspirated motors.

So, naturaly aspirated diesels are also slugs in comparison to turbo diesels

X2.

Everyone loves to conveniently forget that when trumpeting the virtues of diesel over gas. I'd love to see a turbo'd Ford V10 or GM 8.1L go head-to-head with a modern diesel.

Full disclosure, that turbo'd gas motor would get about 4-5mpg (LOL) but the power would be there.

The fuel mileage would probably improve but you would have to really feed it to get the torque of the diesels and then they wouldn't hold up. Plus you are comparing 8+ liters to 6.7 and 6.6 liters. Thank an 8.1 liter turbo diesel and hook them up. Yes the gas would be faster but the diesel would out pull it day in and day out.

True, the GM 8.1L would have a displacement advantage but at 6.8L the V10 would make for a level playing field as displacement goes.

Completely agree that reliability would likely be an issue if one bolted a turbo to the existing gasser block without tearing down & strengthening the internals. But until it exploded it would be fun :W
