16v96

Hi,

You have posted 16v96 in the title and 19v96 in the thread.

I do not know of any DD with this model designation.

There is an older MTU Engine that is a 16V396 which was popular a few years ago.

It's most likely a 16v92 with increased capacity. Heres a link to a company who replace the 16v92 crankshaft to do this, and call it a 16v96.

Pretty interesting link there, thanks for sharing it.

2475 RPM??? How common are parts for these V96 series motors?

It doesnt seem realistic.

Well with a stronger crankshaft, there is no reason you couldn't turn the engine more RPM's as long as the other components are strong enough such as piston rods, pistons, rocker arms and such. They do it with gasoline engines all of the time by stroking them and/or boring them. I don't know how long term durability is.

Hi,

Not an unknown phenomenon in the aircraft industry

It is not so much a stronger crank it is the throw that is altered to increase the stroke from what I understand.

As for parts commonality- Why not ask the dude who builds them and get the answers from source.

Increased power, increased torque (presumably) and increased RPM....all have a knock on effect on gearbox ratios / torque rating, shaft diameter / props.

Hi,

I am pretty sure that they would have to come out and probably go to these guys workshop to get that conversion.

More horsepower? With more displacement, seems likely.
But less fuel consumption? Ooookaaaayyy.....

Less engine wear/longer engine life? Lessee....the pistons travel a longer stroke (twice) per each revolution and turn the same rpm (or more? 2475?) which means that there is a higher piston speed at work here which should equal more heat & wear. Hmmm.

I would suspicion omission of a ringset or two (a hotrodder's trick) and/or additional modifications to the fuel/air delivery systems (modded chip in the DDEC ecu, maybe).

Not purely a 'stroker', but with some pixie dust mixed in as regards the builder's claims?

Actually, Jackie Bivens took some 92 series Detroits and bored them to 96's. He did it with 8's, 12's and 16's. He then used a different custom cam and pistons. They developed more HP and seemed to stay to gether quite well. I'm pretty sure Jackie is still around. I had a client that surveyed a Rybovich with the 8V96's several years ago and Jackie did the engine survey. (Not my choice).

According to Mr. Biven's own website, a replacement crankshaft results in the additional cubes...plus, these are linered bores which would obviate the possibility/need to bore them out, IMHO.

Wasn't aware of that. I just know that the 92 and 96 represents cu inch/cyl. in the Detroits. I guess the longer stroke got the xtra cubes. Oh well.

The V96 engines are modified to 96 cubic inches per cylinder by
All World Power Corporation,www.jackbivens.com, located in Stuart, FL.

Mr. Bivens passed away on 12 May of this year. His son continues to run the business.

I spoke with Jack's son who is running the business. It's headquartered next to ACY in Stuart, FL. They have a set of 16-96's ready to be installed in a vessel now. It's quicker to remove and replace than to rebuild/change inside the engine room. It's normal in many applications to see a reduction in fuel usage at the same speed when you alter the HP of the original diesel engine. On road this is expected- no reason you'd see anything different here so the claim of less fuel used sounds reasonable.

This may be true. But if I was going to go through the trouble of changing engines, I'd end up putting new engines with modern technology rather then modified dinosaurs.
