So I was thinking about the remote IPR
setup on twin pumps, (and the stock pump now that I think about it) and how it is plumbed straight off the pumps.
Then I started thinking about how the flow through design of the regulated return on the fuel system works better than the stock setup.
Here is my question...
Would there be any benefit to removing/ blocking the IPR
from the pump, Feeding the heads from the front ports w the stock feed lines, then using a return line from the back of each head to a block w 1 or 2 IPRs, then dumping back down the front cover to the crank case?
How would using a setup like this affect the pump/s and injectors?
Would this type of IPR
return provide better flow and more consistent pressure to the HPO system?
I know that many times a HPOX line smooths the idle and balances the system. This would basically do the same thing by connecting both heads to the remote IPR
I would like to hear thoughts on this concept from others that have more knowledge on the HPOP
system then I do.
