    • Tuning Tech FS developing dual HPFP fuel system upgrade for the BMW F87 M2 N55B30T0 motor

      This is great news for those who do not necessarily want to add supplemental port fuel injection or drown their motors in methanol. Tuning Tech FS (Frank Smith) has tested a dual HPFP (high pressure fuel pump) system on their F87 M2 for close to a year now which will allow much more fueling headroom while retaining the direct injection system.


      It is currently on the TTFS M2 as well as a customer's track car in Texas that has a turbo upgrade from Pure Turbos:

Our customer's M2 in Texas is a road course car.
      The system is working well on the roadcourse.

      As for the power it will support that range is roughly ~600 whp.

      The system itself is a custom retrofit of the S55 dual HPFP system. The kit will include all the necessary hardware with much of it made up of factory BMW parts.

      TTFS is also considering additional platforms for this dual HPFP retrofit in the future.

      Once this product is finalized and released later this year expect a price point around $5k.

        We thoroughly looked into this a year or so ago, regarding N54 Retrofit. BMW Genuine Parts alone were north of $3,500 IIRC not including any other hardware customizations that maybe required along the way (it seemed it would be largely PNP however). Additionally there needs to be a way to control it as well, yet another cost and development time for a piggyback. In short do not expect TOO Much adjustment via market, unless the BMW parts take a large decrease in cost at some point. This all was discussed on another thread here on BimmerBoost at the time.

        Makes sense. Glad to see it happening though especially when some said it wasn't possible or worth it.

        If I had an M2 I'd definitely look into this.

        I heard XDI had a solution for a factory hpfp swap out to a higher flowing one for F series N55, I believe up to 65% more flow. It should be cheaper but I haven't seen any prices yet. But they have stuff for the focus RS and other cars with DI, so its a promising and potentially cheaper alternative to PI or meth.

        That's for for N55 engines from 3-2012 (not the same pump as n54 and early n55). No need for a piggyback, the N55 DME of the M2 (and other F series N55 from 3-2012) is the same as the m4.

        Yeah there was another thread I meant to post that reply in which was specific to installing S55 HPFP's on an N54. Sounds like the N55 (F series from 3-2012) would be a much better candidate for said swap.

        How much adjusting do you think can be done on OEM parts costs? Or maybe some aftermarket player can put something together?

        Basically more competition or sourcing other pumps but OEM parts are easier to be confident in despite the premium.
