Re: Detroit Diesel 2-stroke Power Capability / Mods?

making 1500 hp from a 8v71 block is possible... how much money do you want to spend?

Re: Detroit Diesel 2-stroke Power Capability / Mods?

Gee, when I rebuilt '71's, (about 30 years ago) it was a hundred bucks a hole, after core refund. You got a liner, with a piston in it on a connecting rod, drop it into the hole and bolt up the conn rod with new bearings. That was on fishing boats, not high performance stuff.

Re: Detroit Diesel 2-stroke Power Capability / Mods?

Some trucks ran 12V71 Jimmies in that era...saw one in an early-70's KW cabover last year (though that had no turbos). 1500HP would be POSSIBLE (there are competition sledpullers making that from a 6-71), but certainly not practical for road use!
Optimism is a mental disorder.
