The HPFP is pretty accessible on the motor, its cam driven a few bolts and you've got it off.

This pump is good for 900 hp at 13.7 volts

This is where I’m lost. I thought the HPFP pump was a positive displacement mechanical pump that there were no upgrades available for.



Are you guys replacing/hot rodding the HPFP pump? Or just feeding the HPFP pump with more fuel from the lift pump(s) which in theory should provide more fuel volume/pressure?



School memy brother. I’m confused.

So do you think with the fuel system upgrades (not the aux injectors) and the bigger turbos there would be enough fuel to make 430+hp on 93 octane? I'm thinking there should be enough fuel. Not sure if 93 would keep from detonating at those boost levels though???

Currently there isn't an upgrade for it. I think there will be one available by the end of the year though. I'm going off Mike's test of upgrading his lift pump which kept the hpfp from dropping athigher rpms.
I think its possible, I have meth injection too as a band aid for fueling and I'm running an e85 mix in with my gas so I'm hoping this pays off. I need to get this thing on the dyno then we'll know for sure.

E85 or straight fuel? i would guess/hope that is a corn measurement but probably straight fuel. that is the e85 walbro you are talking about.

StrawHatShinobi

I'm not positive on the fuel and yeah the e85 walbro

Yes, and I sent a HPFP core off to be upgraded, but I have no idea when it will be available. There is A LOT going on inside that little housing, and it take skills greater than mine to make that happen. I've been given a ETA on the pump, but as Strawhat can confirm, testing new ideas and parts is fun and messy . We will see 500-600 whp EB F150's with just the lift pump and HPFP upgraded in a year or so.

600whp...and who knows how much torque. Damn. These trucks will scoot. Stripped out Tremors will run like supercars down the straight. Lord help you in the corners.

Mats right its been trials and tribulations for sure but I've enjoyed every minute of it.

You can run gas through those Walbro's too.
