Is our hpfp used in any other di?

Is our 3.5 hpfp specific to ford or is it an off the shelf delphi unit? Like the Mazda speeds or vw/audi? Any commonality in displacement of the pumps?
 
I thought it was a rather common bosch...ask fomocosho he reads about our hpfp for fun and in his spare time lol
 
I was just seeing that there are rebuild services and kits to upgrade most other cars/trucks hpfp. So it got me thinking there might be some commonality with one of these kits
 
People aren't willing to put in R&D because of our limited market which I can't blame businesses for.  The fuel system limits are kind of a let down for the platform and will probably be why I go a different direction in the future.

Actually for an oem system it allows for quite a bit of power increase over stock....people simply see that the system is maxxed out but thats at about at least 500 ftlbs of torque at the flywheel...not too shabby for stock fuel system...
 
Just a note... bpd is putting down 617 AWHP with factory fuel pumps.. He does have meth injection... That is the equivalent of almost 800 CHP in an all wheel drive train.
 
So is there a possibility of some of those pump build kits having some commonality? Would you happen to know the pump model number and I will do some Google fu
 
HPD-5

The problem is it's not as simple as slapping on a bigger pump. (which exist)

These pumps are cam driven so we may be maxed by our cam profile and there also may be unknown tuning aspects involved.

Our current pump is capable of generating 3000 PSI but only creates 2150 from the factory.

I may have found somebody who can get us answers but I haven't heard back...yet.



 
According to Geoff@Full-Race they were developing a pump for the truck but after only about 20-30% increase in output it broke the camshaft....
The cost was going to be around $1500 from my understanding, not enough to do E85 so IMHO not worth it.
 
Do you know what specific design changes FullRace made for the truck pump?  Off the top of my head, one would think gearing and materials change would be needed.

It wasn't Full-Race it was Bosch or somebody, the pressure from the pump trying to squeeze the fuel broke the cam in half...
 
That's sad that Ford did not use stronger parts on these engines, knowing that people mod their other models like mustang and focus... they should have assumed same would be done on these turbo cars. They should have left consumers some room to play.

You are kidding right cro?..so what kind of parts should ford have used?..with just a tune the sho can run mid 12's and have 450hp and over 500ftlbs of tq at the crank
 
No, I'm not kidding. Just saying, that camshaft should not snap just like that.

Maybe it had nothing to do with the cam, maybe they altered the spring rate or length and caused the cam to snap. You can't compress fluids. Modifying these pumps isn't a simple proposition, if it was, we wouldn't be having these conversations.
 
So it seems like more displacement would be more reasonable compared to higher pressures for worry of the cam. He's a random idea what about the cam eccentric that operates the pump? Maybe change ramp of it or lift?
