So I am in the process of building a compound setup for my 2v E6 Mack I believe there much tougher then given credit.... just gotta keep it up in rpm and not lug it ..... so I’m going to use a k31 as my high pressure turbo comes off a Detroit series 60 and a s480 as my low pressure turbo I have my fuel setup figured Out so my plan is run it till it quits if it does quit then swap out for a e7 mech engine. Mack truck are what I love but!!! Coming from building quite a few performance Diesel engines I can tell you this Mack’s air flow research has always been behind a k31 will much more air and move it much more Efficiently aka faster spook up so it should be much more snappier and cooler running and and on the big end the s480 will take care I will take pictures when I start and give you a update how it performs
