Contact Eric. You've got me curious. He woulda had to gone bigger to handle E85.

Well Eric said no chips burned for 160's ................ I wonder why 120's but not 160's ?? Not sure what I'm going to do . I'm only going to need the equivalent of 140's max and still have a cushion . Can this be "cheated" with a higher base fuel pressure setting , as long as the pumps can keep up , or will there be drivability issues at low speed / idle ??
Shouldn't be. Higher base psi will help with the fuel atomization.

I assume Sam is using E 85 and needs bigger injectors.

Everything is in my signature .
Twin racetronix 340's , -8 feed -6 return , Caspers Voltbooster ( 15vdc to the pumps ) 6.1 chip Powerlogger .
E85 , logging FP , 10.8 target AFR ( rock steady , chip controlled ) , 80% duty cycle .
I'm working with Mr Spool and adding my Alky injection back on to supplement the fuel system and increasing base fuel pressure .

How much alky are you going to introduce with e85?

Not sure yet . Uncharted territory for me , that's why I'm going to work with Mr Spool to get it dialed in . That guy sprays a whole lot of alky and has been for a very long time !!

120's are much easier to get to idle with pump gas and even they will many times be at under 1% duty cycle at idle. Also, if fuel psi is raised then the DC at idle will need to be dropped even more due to more fuel being produced . Have you logged Fuel PSI at WOT? If its low it will cause high duty cycle at WFO

Post a screen shot of the second pump coming on fuel psi wise

I only have a few logs from BG last year and my Powerlogger had defaulted to " base " settings in which my wideband O2 wasn't AEM inline and my aux inputs #1 & #2 defaulted to voltage ( from the sensor ) instead of pressures . I can say that the second pump would be turning on in under .5 seconds at 15psi . Do you think the second pump isn't coming on ?? In past logs when fuel pressure was recording I never saw a jump from the other pump but boost was rising very fast to 30psi and FP rose right with it . The BG logs were not very helpful .
