Given the numbers the 6cyl cum ons get I would think that thing should be able to hit 500hp, 1000lb/ft with a bit of work.
Did they make an ISB version of the 4BT? I've heard that the 12V pumps on a 24V ISB can crank some serious HP, like 800HP, 1200 lb/ft easy hands down, with some other mods of course.
