Caterpillar 3208 Solutions This sub-forum is hosted by Mike Hohnstein who has been at this kind of thing for 50+ years now, guess I'm addicted. The saga has been all about progressively larger shop space since then. Honestly, never wanted to get into the CAT 3208's that were originally considered to be a throwaway engine but that's all that works in a FC in my world. Same thing with my Ford toter, that came with a NA, too much effort to hang in a 6, so been at it with the CAT V-8 for 20 years now. In reality you can get excellent life out of a CAT 3208 if it's built correctly. Post your questions about the CAT 3208 engines here and Mike will try to help you out.

Default 250HP vs 300HP

Hello,

Does anyone know the difference between the 250 and 300HP versions of the 3208? Did Caterpillar simply add an ATACC and a fuel pump setting to gain the extra 50HP, or was there more to it?

Roller camshaft & lifters, 3-ring pistons, larger oil cooler and numerous other changes. Many parts will not interchange; that's a reason the Arrangement number is needed when ordering parts. Bill Pape or Mike H. can give a better answer to your question.

I see the turbo and fuel pump are also different. Good to know.

Use .110 stepper pumps in injection pump, turn fuel screw out to limit, verify the 250 hp turbo is sound, add CAC and you'll be plenty close to a 300 with out the need to spin it up to 2800 rpm, 2500 is safe high limit, 2300 is a good cruise speed.
The International medium duty radiator and Bluebird CAC I applied to the 31 works stellar. Search around, posted the pics a numbers a while ago.
