Mach 5-6 Injectors with HO Pump?

[GO 4LO]

Hey, guys,

I've seen on a few posts that it's not recommended to run any bigger than a Mach 4 with the HO VP44. Why is this? I understand the HO pump reaches its fueling limit in the 550hp range, but will running bigger injectors cause problems of some kind, or is it just not recommended because you get no more performance for your money with M6's than M4's? TIA.

I've wondered about this also. How do you get an HO over 500hp if you can't run injectors bigger than Mach 4's?
