Just read that there will be new CAT C32B that will be the 2,400hp MTU competitor but haven’t seen much more as of yet. Any news on the supposed 3,000HP MTUs?
CAT came out with an engine to rival the 16v2000's with the proper weight and size a while back. They built and tested like 6 sets. They asked the heavy machinery division if they could use it, the generator division, they said no. It never got approved, so the project was canned.
They are going to produce the motor in 2000, 2200 and 2400 hp versions. The larger hp will have sequential turbos. Supposedly will be ready for installs in January. The up graded motors cat was going to produce a few years back were on the trucks ready to deliver when they pulled the plug. They really hurt a few builds waiting for them. Yes construction dictates the motors they build, marine is just a tiny fraction the size.
All the engine manufacturers have larger for construction or commercial, just a matter of tuning for yachts and also just the physical size issue.
No the larger are too heavy for the HP output, so only suited to displacement yachts (mega yachts). CAT came out with a motor above C32, that was compact and light weight, but since the marine industry (yachts) comprises 5% of their sales, and nobody cares about weight in an earth mover, it never got passed.
The first engine has been officially announced. Will the 2200 and 2400hp variants be based on the same 12 cylinder design? Should have a nice pickup having 2025hp in the same size package as the C32.
Yes same package as c32 with additional turbo. The 2025 is same dimensions as current, drop in ready. The 2200 and 2400 are dimensionally larger but don't know exactly how big. Spencer and scarbrough are each building a new boat specially for these new motors.
With this kind of horse power, what could the duty & service cycles be? How often can you actually use up that much HP and how often between rebuilds?
Makes one wonder if, while they were at that, they also thought to fit some half decent intercoolers...
Interesting to hear that... "Sea water system is electrically bonded, so there is no longer zinc anodes to replace." I always wondered why they never followed the route the Germans took 30+years ago. It's a bit disappointing to hear now that they simply needed so much time to learn. Maybe they should have moved engines design to PRC, to speed up development...
No, they are supposedly much better. Multiple injections of fuel per cycle to help with noise per cat rep up to 1200 rpm.
