Dual in tank fuel pump arrived!

[EcoBrick Bob]

I understand... perhaps a LONG LONG LONG time...  But I can dream... and wish and hope...

If our drive shaft design for DI pump could be incorporated into a bigger Bosch,  wouldn't that be nice.  Are our injectors unique?  Could larger DI injectors be combined with ours so that they would fit?  Assuming not... but there are some really great innovators out there.

Do we know what our injectors max flow is. I am sure it has been posted somewhere I'm just to lazy to look. But in the mazdaspeed world the aftermarket pump internals made a huge difference allowing the car (speed 3 in this case) to go from a little below 300 whp to over 400whp. I would say that is a considerable jump.

If our injectors have similar flow capacity and they find a way to get similar improvement out of the hpfp as they did then we are looking at a much higher power gain then them seeing  as we have 2 more injectors. If are injector flow is crap then ignore my rant

I'm betting that the injectors are able to flow quite a bit.  Seems like many DI systems (diesel or gas) are limited by the HPFP and a drop in rail pressure...injectors are somewhat simple in how they work on a common rail type DI motor in that they are told to open at a certain time for a certain amount of time (pulse width).  E85 could put them past their limit pretty easy, but that won't be known until a HPFP comes out...

I have some super exciting news coming out because of this work, just waiting for everything to be finalized.

How long are we going to have to wait for this epic news its only been about 45min since your post and I am already going insane :biggrin: lol. Does if have to do with hpfp or your dual pump system?

 

[4DRHTRD]

Probably about a week or so until everything is finalized. I should be able to offer a fuel system to support around 600WHP on pump gas for around $1K. No aux injectors required, just need to do some continued testing and verification and some parts are still being developed.
We're also working to make it as plug and play as possible, it will require running a new power line from front to back but hopefully that will be all.

If what you say is true that is truly epic. The simpler it is the more appealing it is to the masses. Can't wait exciting times. You rock 4dr

4dr been 2weeks any update ?

Soon, just waiting for the final parts and pieces to come together.

Anxiously waiting to know what I will be sending my money on

600rwhp on pump gas would be about 420rwhp on E85.  It would be nice to be able to get to 500rwhp on E85, but that sounds like it might take some upgrades to HPFP or injectors.  If the HPFP was oil driven like older HEUI diesel fuel injection systems High pressure oil pumps then we could turn to someone like Stealth Industries and get something like this little bad boy that my Dad has on his 2000 Excursion Powerstroke which he has tuned up to somewhere between 500 and 600rwhp.

In fact we might end up in the long rung looking at a manufacturer like Stealth industries to build up a from the ground up Billet version of the stock pump built to provide higher volumes and acceptable pressures.

Is that pump electric or driven by belt?

 

[05yellowgt]

It is gear driven.  Actually, the more I think about it, there isn't MUCH difference between the HPOP from a 7.3 Diesel and an HPFP from the 3.5 ecoboost.  The HPOP is driven by the timing gear set (the HPOP sits in the valley of the 7.3 at the front of the motor) and the HPFP is driven by one of the Cams in the OHC design of the 3.5.  The only other differences are that the HPOP pressurizes engine oil to drive the hydraulically actuated HEUI DI fuel injectors and the HPFP pressurizes the fuel itself on the ecoboost to be injected by the electronically actuated DI injectors.

Provided that the HPFP can be improved in it's ability to provide addtional volume, while fitting into the same general footprint as the stock HPFP, it could prove to be a quite interesting option (though by no means cheap).
