Message: [QUOTE="Zeb, post: 1528672, member: 30304"] If you look strictly at the intensifier/plunger ratio hybrids do have a lower nozzle pressure, but there are several things that factor in. Fuel in time as The Brad mentioned. You can only get the intensifier to move so fast so therefore you can only get the plunger to travel so fast. If you have too large a nozzle, pressure can actually drop at the nozzle because the orifice can unload fuel faster than the plunger can travel down to keep pressure on it. When that happens, actual nozzle pressure tanks, smoke and egt increase, and power starts to drop. Properly sized, and up to a certain point, conventionals can have more nozzle pressure, and make a little more power per cc than a hybrid. But, a hybrid can move a greater quantity of fuel per the same amount of plunger travel, so even tho it has a slightly lower (calculated) pressure, there is a more consistent pressure at the nozzle, and a greater quantity of fuel available in the same injection window, so therefore often a cleaner burn, less smoke and egt issues, and more power.
