Hey all,
Wanted to gauge interest in this as I've been contacted a couple times recently about LPFP setups for big numbers.
I've been running a return style system for about 8 months now and frankly for those that are going to want to be pushing big numbers without meth...I think this is going to be the direction to go. Especially if you want to push big numbers and E85. Now that there is a lot of work being done on the HPFP side, talk about port injection, big singles being installed...a robust LPFP setup is going to be key.
A couple of advantages to a return style system.
1. Your potential fuel supply ceiling is substantially improved. (more info on that to come)
2. You can run around in stock mode with the DME happy but the minute you go WOT...:scared-eek:... the DME no longer cares what the LPFP sensor sees as long as it's not diving. Then once you let off the gas...back to stock mode :eusa-clap:
3. All in tank systems remain 100% functional with 1 minor difference...no internal POS regulator!
4. Everything becomes plug and play and returning to stock isn't an issue if you save those parts.
5. No trying to get (and control) another pump in the tank.
6. JB4 can very easily control this or you can do it by other means...I've done both. :happy-partydance:
While it seems like it would be a huge PITA...it really isn't that bad especially if it's done right and everything is provided for you. :music-rockout: Having done this and given all the work I'm doing on the LPFP side, it seems it would be the natural progression for me.
I already have a couple things going on LPFP in tank side...adding this would make for a system that is potentially capable of 1000+ horsepower. :awesome: (Based on pump specs...will be verifying flows and then one of you guys with the big guns will have to verify on the street)
Just curious to see what the interest is before I start gathering information and documenting things.
As an example...here is a screen shot of my LPFP system in action....
The LPFP side of things on E82

The HPFP (I target 2500 psi and have supplemental injection which is starting to be talked about more these days) Also notice on shifts...the HPFP pressures don't dive :naughty: I spend the majority of my time above target.

Now...all that said..it's not going to be the cheapest setup.
Estimated costs to do it RIGHT is right at $1500 but:
1. It's done right
2. You can return to stock
3. It'll support big numbers.
Now...of course there are ways to get the costs down if I can work with vendors (providing there is enough interest) less quality parts (not really interested in that so that's not going to happen) or you don't care about returning to stock and want to save a couple hundred bucks via core charges and refunds.
Again, just gauging interest...not offering anything for sale or making any promises.
