Message: [QUOTE="Charles, post: 1566458, member: 103"] Old thread.... but close to a topic I am working through right now so I will respond in case it may be useful down the line. IIRC.... with larger nozzles, like a 200 or 400 for instance, the Hybrid flows more fuel with the same pw and icp on the bench and in the truck. The only way that is possible is if it achieves a higher injection pressure behind that nozzle. If we could graph actual injection pressure vs icp for a B-code and a hybrid with both running say a 200 EDM and plot ICP on the X-axis and actual injection pressure on the Y-axis, I expect that you would see the B-code graph start off and climb as icp increased but start to lay down and just barely be increasing at some point, my hunch being, beyond 2100 to 2500 or so psi. I expect you would see the hybrid start lower but climb and continue to climb right on past 2500 and 2800 to 3000 or so and then lay down again. So basically... the B-code is less dynamic. You can achieve the B-code injection pressure down low by writing your programming to call for more icp to pw ratio. But the B-code can never keep up on the top, no matter what you do. Now VOP..... that's an entirely different topic... And lastly..... B-code is a 6:1 and it outflows the A-code, which is a 7:1. Hybrid is a 5:1 and it outflows the 6:1 B-code..... anybody want to guess what will happen with an overbored body, bushed down to a machined intensifier piston atop a B-code plunger in a 4:1.... or a 3:1 ratio..... YEP.... It will happen again... but maybe from 3000 - 3500psi, or 3500 - 4000psi.... [/QUOTE]
