What are the limits of the 8.1M injectors?
I still have a set and was just wondering how far they can be pushed.
Im running a Bosch 044 pump so i have enough there to raise the Fuel pressure.
Just kinda curious how much more they would flow if the FP was raised to say 80psi base pressure or so.

Gonna end up goin with the borg warner 72mm with the large T6 and 1.1AR exhaust or something similar.

I wish i had my formulas that were on my old laptop for the injectors. Could figure it out from that.

If they are rated at 43.8 at 60psi they should be around 55 at 80psi?

 

They are rated at 43lbs/hr at 58psi. My experience with them and a return system, stock pressures, I make 505rwhp at 11psi with my 4.8 and a single M15 meth nozzle and the injectors where at 105% DC.

 

I have a aeromotive 1:1 regulator. And i think a returnless fuel rail somewhere. I wonder what they would be capable of at 80psi base? 90psi @ 10# boost

 

If I figured it right, they will act like 54lbs, injectors at 80 psi of fuel pressure.

 

I'm pretty sure you could also have FIC make them bigger for $20 each.

 

I need to look up FIC. Ha.
I wish i wouldnt have sold my 73# injecotrs now dangit.
