525 efi stock fuel system capabilities
 
525 efi stock fuel system. How much hp can the stock pumps and injectors support?

700 HP plus on stock injectors. But intake will not allow enough air anything after 600hp even with larger throttle body.

Thanks. I am replacing the intake with a better flowing setup.

What Intake? Keep in mind, a 525 uses honda/keihan style injectors ( 22 MM grommet seal on bottom/ 11.5/12mm upper feed) so there are very few intakes that would use those injectors beside early 454/502 mags, 525s and hondas, Smitty

So they aren’t one off unicorn piss molded into a custom injector made on the USA for one and only one guy that repairs 120 ecms a day yet has enough time to be on here all day?
just a Honda based injector. That’s cool
