I currently have RC 550's and was wondering if my fuel rail needs to be modded or bored to fit the 750's, also how much HP can 750's support?

 

750's will fit just like your 550's... I think there good up to 500hp +/-.

 

i personally hate those injectors. everyone will have their own opinion but id go with a peak and hold injector if u plan to go bigger than a 550

but they do fit the same

I have a set of RC 750 sat. on a stock rail/fpr. Boosted for 15k and I didn't have to do anything special to use them.

 

Alright thanks for the quick responses guys

Is there a reason you hate them? Is there advantages in getting peak and hold compared to the saturated?

Why do you hate them? I have ran those injectors in my car for almost 2 years without any issues. They tune out fine and run great at any pulsewidth. *shrug*

 

i've just had mixed results in getting a good idle with them. some work great others idle very lumpy, havent figured out exactly why yet
