Uprate Turbocharger:

Recommended Posts

I've got this 77 R795 and it has an ENDT865 engine which smokes very heavy due to overfueling. I mean somebody's got the fuel delivery really turned up. The engine runs fair when cold, and very well when warmed up. It does pull strong with, and without a load, but needs to clean itself out on off idle acceleration. I've only pulled one loaded trailer with it and that was not really for any distance but I was impressed. I would like to make a little more power with this engine by shoving some more air down it's throat but not hurt it. It appears to have a reman turbocharger, (turbin housing is very lightly rusted) and the compressor side is A/R .55, (small). I have no idea to the turbin side as there is no stamping and I haven't found an ID tag yet. This fit is as factory so I assume it is a like replacement to the original.

I have absolutely no V8 Mack engine experience so I'm asking for suggestions. Would I be out of line to try and acheive 425 horses, (reliable) out of this engine? That is 100 more that factory rated. I know it can be done, but at what cost to service life if driven responsibly?

Thanks,

Rob
