26575, S-AFC and fuel pressure
Posted by Dave_FL, Jul-15-02 10:37 AM
I am going to install these 440cc injectors here pretty soon. I already have the s-afc installed. I have the HRC FPR that came with the kit. Do I have to adjust the fuel pressure on the FPR when I start using the s-afc with the new 440's? Wouldnt the fuel pressure be way to high for the 440's?

Yup, you'll have to lower the idle fuel pressure. For 440cc's, you'll probably want to set it about 40 psi, then you could always make minor adjustments from that.

I'm about to tune almost the same setup....415cc injectors with the HRC FPR and S-AFC. The base fuel pressure is set with the vacuum line hooked up, right??

Thanks!

What's a good static pressure for the 30lb mustang injectors and hahn's fpr? Would i actually need a SAFC for that setup (not need, but would it be helpful?). I'm buying a set on ebay right now, if anybody's interested in splitting it.
