Charles replied to the thread Heui Injection.I think with the reality that ports don't flow into open air and that there is a piston in the way, as air pumps, the 7.3 and the 12v... -
Charles replied to the thread Heui Injection.The beauty is..... it's tied to crank.... So no matter what speed you spin it, the fuel goes in the hole in the same degrees crank for...
-
Charles replied to the thread Heui Injection.Try some orifice size vs pressure calculations for how much pressure will move 300cc of diesel in 3ms across a 7 x 12 nozzle. The...
-
Charles replied to the thread Heui Injection.I just suggested that a HEUI with a 200 nozzle could easily be running injection pressures in the sub 9k psi range... A 200 nozzle can...
-
Charles replied to the thread Heui Injection.The only reason we were fighting the IDM before was because the plunger travel was not tied to the crankshaft rotation. With HEUI the...

Charles replied to the thread Heui Injection.You size your nozzle for your intended rpm and fueling.
-
Charles replied to the thread Heui Injection.No, the MEUI system is tied to crank rotation, just like a P-pump, so pw keeps dropping as rpm increases for the same fuel quantity to...
-
Charles replied to the thread Heui Injection.I was doing some blunt pressure vs flow calculations as a reality check for a second, and if you imagined a 7 holer with 0.012"...
-
Charles replied to the thread Heui Injection.I have talked to Joe at Scheid and Ron at Hypermax and everyone else I could think of.... it should work. I have a couple Mack E7 Unit...
-
Charles replied to the thread Heui Injection.I think a pump body to hold the unit pumps together exactly like P&B's on an inline P7100. Hell, the Mack EUP's even have staggered two...
-
Charles replied to the thread Heui Injection.Yeah...... F... common rail. Not interested in playing electrical gymnastics to run a system the truck is NOT already built for, in...
-
Charles replied to the thread Heui Injection.I cannot express how exciting this concept is.... I have checked, rechecked and checked my math again....MEUI technology IS GOING TO...
-
Charles replied to the thread Heui Injection.If you injected the full quantity that the stock E7 produces 1650ft/lbs with but sized your nozzle flow to keep it from overpressurizing...
-
Charles replied to the thread Heui Injection.To add..... ever DRIVEN a MEUI truck? MEUI is one of the reasons the Cat 3406E is one of the greatest engines ever. Drive one.... it...
-
Charles replied to the thread Heui Injection.Injection pressure is a function of plunger travel speed (cam rpm, cam lobe profile) and plunger diameter, vs nozzle orifice flowable...
