BIG A CODE INJECTORS?

I am sure you can have 450HP with some A's, but it wont be as easy as you could with a set of Hybrids.

I think we have gotten away from the subject a little. The only point I was trying to make was that if 3000PSI is demanded from your HPOP the HPOP doesn't know or care which injector is in front of it. The HPOP will pump as much volume as it takes to try and maintain that 3000PSI which will be the same as the intensifier pistons are the same. It's the additional oil flow or volume the A code will need to maintain that 3000PSI for a longer time because its barrel is smaller and the plunger must travel farther to inject the same amount of fuel and also taking more time that will hinder it. There by flow not so much as pressure is the problem on high HP engines ,but shouldn't be as much a problem on lower HP engines. Of course if the HPOP can't keep up the pressure will also be low. I was wondering at what point or HP range is the Hybrid truely at an advantage. I know at stock levels the A is best and at 600HP+ Hybrid is better, but where is the split between the two as to which one is better?
