HPFP And LPFP cobb

Boosted_N54 · 12-05-2014, 03:02 PM

Were should the hpfp and lpfp idle on cobb AP when monitoring. I get around 70 idle for Low and about 700 idle for High

LPFP PSI always targets 72.5PSI flat, regardless of load or RPM.

At idle that looks about right for HPFP PSI.

What's the concern?

No concern I just want to make sure what I'm looking at when monitoring hpfp and lpfp is correct . I don't want to be monitoring it and not know if what I'm looking at is good or bad.

Also lpfp does twitch around 72-73

thanks

Sounds fine to me.

LPFP PSI will always vary - my point was just that the DME targets 72.5PSI across the board. Depending on several factors it may be above or below target while driving.

on a WOT i'd never want to see LPFP PSI drop below 50PSI, and i'd never want to see HPFP PSI drop below 1.5K PSI.

Thanks man. at cold start the hpfp idles at above 1200 or around and then it settles down at around low 700

Mine is doing the same thing as yours so I'm guessing that our hpfp's are fine
