Subject: Re: 3208 power enhancments Author: Jeff Miller [ Next Thread | Previous Thread | Next Message | Previous Message ] Date Posted: 01/ 2/ 03, 9:52pm In reply to: Mike Hipster 's message, "3208 power enhancments" on 01/ 1/ 03, 9:45pm Mike: I'm interested in your upgrades to the FC, had fun upping power in my old '77 FC-na with different injectors/timing/pump/gears. I currently have the 250hp in my '84 FC. I'm told that the 250hp has the roller cam/lifters and is essentially the same engine internally (cam, piston oil sprays, etc.) as the 300hp ATAAC engine. I have considered adding an aftercooler beneath the coach, only place it'll fit, but am not sure the current pump and injectors have the capacity for the fuel flow necessary for 300hp (although a friend at Cat tells me that he believes that they are the same?). I'm also looking for more intake airflow, I can only get around 14psi boost, probably because of the less than favorable intake design which I'll be changing. I'll probably be turning the full-load point up to 2800 soon, will see what that buys me in pulling power. I haven't messed with the rack, I am not a big fan of black smoke, will work on air intake first. The 300hp went into the '87-'89 FC but with a different (ZF) tranny, and the aftercooler is in front of the radiator with a different grille to make the room. I have the '87 grille on my coach, it buys me about 2" more in front of the radiator, not enough for the cooler. I'm also told that the MT-643 can't handle the power, is rated at 250hp, can that be changed or will I need a different trans? Your 225hp has a different torque converter also, matched to the power curve of the 225. The synthetic fluid keeps it cool so far. Also use RedLine Diesel WaterWetter to help keep water temp down, but it probably won't keep it down for long if I add 50hp. Keep me up to date on your thoughts and mods, I'm happy to see someone else here breathing some life into these critters, sounds like you're havng a good time at it and know what you're doing.
