Subject: RE:Do I need an AFPR? by dan0617 on 2008/2/29 3:26:09 I think you do need one at this point. I have a Holley adjustable regulator that came on the fuel rails with the HSR intake and so far I don't like it. I hate the tiny little adjustment screw that you have to pull the vac line off to adjust. I'd rather have a big knob. More importantly, my car pulls 12 inches of vacuum at 850 rpm idle. I think that is decent vacuum, but it doesn't pull the fuel pressure down much. If I hold the throttle at about 1300 or so rpms it holds more vacuum and pulls the fuel pressure down more. I'm running a little rich at idle and I think it is because the regulator doesn't let the vacuum pull the pressure down far enough. Don't know how to fix it yet, luckily it isn't too bad. Smells rich and blinks a rich flag on and off while datalogging but no smoke out the exhaust and it will idle all day without loading up and dropping the rpms so maybe it isn't that big a deal. |
