250hp to 300hp part-time
« on: March 09, 2007, 08:27:02 PM »

i hope this is the right catagory...
i'm hoping someone here has a little insite of the boost setup in my mh:

in 91 my cummins 8.3 was offered in 250 hp, whats the difference in the 300hp engine in the next few years? is it more boost? i have turbo experience but want to know a little before i just add more boost which actually will be only when i need it situations. the rest of the time it would remain at the stock 250 level...
at times i may be flat pulling my f250 (8000lbs) in the mountains is why im asking. the rest of the time will be a jeep wrangler on a trailer.

also, is this fuel system able to handle the little bump in boost?
