On a procharger D1 or F1 will this injector size be good for 700RWHP? I have twin walbros , high flow fuel rails , and upgraded fuel lines will this be enough or do I need 72lbs? I made 560RWHP on 50lbs almost maxing them out on low comp 408 stroker on a P1.

In theory 60lb will support about 750 rwhp.

That should be plenty..

I heard only with a turbo that this could be done because of parisitic loss from the having to drive belts for the blower

The type of until making the boost has no bearing on the injector's ability to deliver fuel.

I was looking thru your build and it looks awesome. When are you getting numbers on that bad boy.

Those injectors are 72 pounders at 58 psi. They will be more than enough with a good boost ref regulator set at no less than 58 psi base.

Hopefully, those are what I went with for my my new setup. When I did the calculating on the RC Eng. site they came up fine. I'm shooting for 700rwhp also. Pretty much the same fuel setup you have also.

Are you talking about from the 60lbs are 72lbs at 58 psi?

Pretty much, because it's industry standard to rate them at 43.5psi.

Those injectors will go over 800rwhp. Mightymouse made 852rwhp with them at a higher than stock base pressure. Their design makes them quite stable and consistent at higher rail pressures...

I'm spraying meth too, but my injector duty cycle is around 85% with my 60lbers see sig for power level.

forgot to mention that my fuel pressure regulator is boost referenced also and I have 60psi at idle with the line connected.

Mr.Big

No issue here!!! Mototron 60lbers at 60lbs also...

Thanks for all the info guys.

My fuel pressure shoots up to 70psi when I am at WOT off the wastegate spring, but I also have a return style fuel system. I am using 60lb injectors.

me too 60 lbrs are plenty good to over 850whp with a return style system and fpr.
