Yours and mine also. Just curious if anyone went through with their diesel projects or did they hit a brick wall and gave up. Does anyone know if any diesel packages came out since last year besides the 480hp Yanmar. Thanks Jeff

you have to hit Marine diesel, go to Tigershark. 400hp @4000rpm and 948tq. It looks smaller than a Yanmar and appears it is the appr same size as a big block. Any one have any info, thanks Jeff

Jeff, I spoke to the guys who run this co a couple of years back.
They were on the R&D team for mercs 525.
This is a direct plug and play replacement for a chevy big block.
I'd give them a call, and check on their dealer/service network, probably not as extensive as yanmar/cummins/cat.
But diesel is the wave of the future.... w/ audi winning at Sebring w/ one.

btw, i posted the link to marine diesel usa on page 8 of this thread and i'm sure i discussed it other places. I think it may be a smart way to go. These guys are putting their power into many test applications overseas.

The problem with the Duramax is, whilst capable of making huge power for a diesel, it revs pretty low, around 3k I think, so the torque is massive, and will eat any regular drives.
What's needed is a motor that revs in excess of 4/4.5k, and preferably light alloy, then we'd be cooking with gas.

My GM 6.5s are in their 6th season this year, and i've not broken a drive yet (Bravo1's), that's with 325 hp and circa 3900 rpm.

Why don't you get a stronger outdrive and you can use the Duramax to its fullest potential?
