XVI Power Introduces V-16 LS Marine Engine in Miami


Now Steve Morris is building a V-16 monster of his own for a supercar maker from Dubai. I don't know about the supercar, but a detuned version in a big cat...maybe a plausible turbine alternative. Both are out of Michigan, but Morris does have lots of marine history too from what I remember.

Edit: sorry, YT links don't seem to work for me? Pull up youtube, copy & paste /watch?v=8jdh-Psq3Ec to see the 4515 hp quad turbo engine dyno run.

The Devel products are crazy ( in a good way) if you can afford it
OSO isn't allowing links to Youtube??? so if anyone is interested, quick search in youtube for

The Crazy 5,000hp Devel Sixteen is REAL! FIRST LOOK

has the prototypes (incl. 6x6) and the "production cars"

Problem developing a v-16 for marine is someone has to dig deep, stay loyal to the development over the long haul time-frame and basically fund the trial and errors of the engine builder the develop their product
