Adrenaline HPOP Mileage increase?

Re: Adrenaline HPOP Mileage increase?

I would like to get one. They have only been available for maybe 60 days. Talk is 2MPG when towing, but I haven't seen an actual log.

Re: Adrenaline HPOP Mileage increase?

Someone posted on another site that they saw about a .5 mpg increase. It's going to vary from person to person, probably depending on how bad your injectors actually need the extra oil pressure.

It's not a pressure increase, it's a volume increase. That's something that makes the Adrenalin different.

Yes, but if you run out of volume your pressure drops and the pressure is what makes sure it all gets in there and atomized correctly. The main reason for bigger HPOP's is because as your RPM or injector plunger volume increases your will not have enough volume to keep up the pressure. So volume = pressure in this instance.

Not as I understand it. If you have questions, probably good to talk to Bob Riley.
