Message: [QUOTE="Charles, post: 1566087, member: 103"] MEUI technology was before CR and some applications exceed 36k psi, stock.... as a reference for how down to party this tech is from the factory. The EUP setup on the Macks injects enough fuel for 1650 ish ft/lbs on the E7... stock.... but keep in mind, that's a stock program. Think about a stock program on a set of AD's in a 7.3 vs what a HEUI is capable of..... Lastly, the 1650ft/lbs is the stock injection quantity times SIX units..... we have 8 units.... So on stock program pw and timing, assuming similar BSFC, which is a good assumption for most DI diesel engines, 2 more unit pumps and injectors is an easy 2000ft/lb of available fuel at the factory pw and rpm.... The faster you spin it, the harder it injects and pressure rises, in fact, care would have to be taken not to get way high on pressure and rip the pump apart or blow lines or nozzles at high rpm. I assure you, those cam driven plungers won't lay down on you up top, just the opposite. And, as rpm climbs, the available injection stroke INCREASES.... as timing is advanced and activates sooner and sooner into the stroke. Max late generation CR pressure, but with EIGHT pumping units, each flowing around 400cc STOCK..... So, imagine, 30k+ psi Commonrail, with 3200cc worth of pump displacement available.... STOCK.... that's what we're talking about. That's factory settings. That ain't on your grandpa's new CR dodge... Is anybody out there following? [/QUOTE]
