thank you for this thread. I was actually just discussing today while lining up about $2000 worth of maintenance on my 2016 340i. my logs look good and besides my jb4, BMW intake, and soon to be catless DP, I can't see needing the fuel pump upgrade in my car at the moment.
saved me hours of research |

I've contacted the admins about it, I recommended they make the official threads for MHD, BM3, this thread, and the log review thread a sticker. Unfortunately I never heard anything back. Maybe if enough people suggest it.

So we tried E45-E50 on the Pure800 with Dorch Engineering Stage 1 HPFP and rail pressure is dropping quite a bit. Look's like i'm gonna be going with the Stage 2 pump sooner than expected. In the meantime i'm gonna drop it down to E30-E35 and see what kind of results we can get.

I highly recommend Dorch's pumps! I'm currently running their Stage 1 HPFP on E40 on my Pure800 and so far no rail pressure loss. We'll see what it does when it gets dialed in.

How does this do on a stock turbo or just an upgraded turbo on pump gas 93, Is it worth it either one?
By me its very hard to find any kind of race fuel to keep it a daily |

Pump fuel and HPFP upgrades seems to be a reoccurring question. I think based on Pure's testing alone, if you will only ever run pump fuel the Supra HPFP is all you need. They ran out of octane before running out of fuel from my understanding.
As soon as you add any E85 you should start looking at the stage 1 pumps, stage 2 if you have an upgraded turbo. |

I have decided to go with the Dorch stage 2 pump. I have a B58tu pump available if anyone wants to take it. I have not installed the pump yet and the connector is already repositioned.

Have someone seen any hp gain with upgrade hpfp only on pump fuel ?
Stage 2 RON 93 Octane for example. I´m running MHD Stage 2 (/93 Octane - 98 Ron i Europe ) I´m thinking getting supra hpfp and go costum tune. |

I don't think we've seen any rail pressure drops with pump fuel on a stock turbo/stock HPFP with a good flash tune. All that being said, custom tune is always going to get you better results than OTS and an upgraded HPFP will give the tuner even more headroom to work with. You might see some gains, but they won't be what you'd get from the upgraded HPFP if you were using an ethanol blend.

If it were me, I'd save up a bit and do a turbo upgrade + hpfp upgrade at the same time. Then the custom tune with pump gas will net some serious gains.
