Official B58 HPFP Options Thread

There's a lot of talk on HPFP upgrades recently and I think it'd be worth making a dedicated thread to discuss them and also show everyone what is currently available and where you can buy them from.

HDP5 Evo (Stock B58 HPFP)

The HDP5 Evo is the HPFP the B58 comes with stock. It's an upgraded version of the N55 HPFP (HDP5). The stock HPFP isn't capable of maxing out the stock turbo without supplemental fueling such as WMI, CPI, PI, etc.

1. HDP6 (B58TU "Supra" HPFP)

The HDP6 is the stock B58TU (Supra) and it flows a lot more fuel than the stock pump. So far there is about a dozen people (that I know of) running it including Pure Turbo, they have tested their new Pure 800 turbo up to 603whp/702wtq on 93oct.

PNP: Somewhat. Requires extending the wiring harness to reach the connector.

Possible Concerns/Drawbacks:

1. This Pump Is Designed To Operate At Double Ours (5000+PSI): This has also been told to me from Frank @ TTFS/XDI.

Originally Posted by OzBMR

I think it's important to include that the pressure relief valve (pressure regulator) for HDP6 is fixed at 400 bar and although the tuning of the fuel quantity control valve via PWM signal can target 200 bar (2900 PSI) there may be instances where pressure far exceeds that, potentially over 5800 PSI.

Our HDEV 5.2 injectors are designed for 200 bar

Both XDI-35 and Dorch Stage 1 have a 2900 PSI design and matched pressure relief valve

Is this True? Yes; but I have not heard of anyone's pumps failing or causing damage to their B58. Will update if anything changes.

2. Can Cause Damage To Cam Follower: There is a Facebook user on B58 Enthusiasts saying that after 2000km his B58TU pump caused damage to his cam follower and resulted in metal in the oil pan.

Is This True? Unknown, but doubtful. He has not provided any proof of this or any further details to back up his claims. The only reason I am mentioning it is I feel as if everyone should have information available so they can draw their own conclusions. I personally do not think this will be an issue as i've heard nothing but success stories from people who have been running this pump.

Dorch Engineering has released their Stage 1/2 HPFP’s for the B58 (as well as N55) at very affordable pricing. Based on the data they have provided their Stage 1 pump will offer similar performance to the B58TU pump, while their Stage 2 will offer people who are looking for even more power a great option.

Logs:

These are my personal logs after installing the DE Stage 1 HPFP, this is a custom E50 Tune by Wedge, Dyno’d at 470WHP/520WTQ

Wedge E50 V6 3rd Gear (Dorch HPFP)
Wedge E50 V6 5th Gear Dyno

Logs on Pure800:

These are also some logs of my current progress on the Pure 800 on E40.

**I will update when more information becomes available**

PNP: Yes - Dorch provides a wiring harness extension that just plugs right in and MHD/BM3 both provide a Flash Option that loads the pump calibration.

Where To Buy:
1. Dorch Engineering Stage 1 HPFP
2. Dorch Engineering Stage 2 HPFP

My Personal Thoughts:

My thoughts on the Dorch Stage 1 HPFP so far:

I would highly recommend this pump to anyone who is looking to get more power out of their stock turbo or upgraded turbo. We were able to push my stock turbo 340i to 470WHP/520WTQ using this pump, which I believe we could have pushed more if it weren’t for the fact my spark plugs were messed up (which I discovered a week after the dyno session).

I’d highly recommend the Stage 1 HPFP to anyone planning to use pump gas on upgraded turbo (I have the Pure800), but if you plan to run heavy E85 Mix’s (E40,E50,E60+) i’d recommend the Stage 2 pump which I am waiting to be delivered.



Dyno Results:

Here are my dyno results from using the DE Stage 1 on E50. Pump still had plenty of headroom.

XDI is a well known player in the HPFP game, they offered the XDI-35 for the N55 with great results. They now have a B58 XDI-35 that is currently in development and hasn't been released yet, but if you contact them directly you can purchase a pre-release pump.

PNP: Yes. MHD/BM3(?) Flash Option for XDI HPFP.

Where To Buy:
1. Contact XDI/TTFS via E-Mail

4. Spool Performance HPFP

From Spools Website:

The FX-150 is an upgraded high-pressure fuel pump for the F series N55 and B58 motors. The pump features a bigger bore size than stock that translates into roughly 50% more flow when compared to stock. The pump is completely E85 compatible and fully plug and play with no cutting or splicing of any kind required. The added flow will let you run much higher ethanol concentrations and also allow fueling for bigger turbos.

PNP: No - Requires a custom tune to load pump calibration.

Where To Buy:
1. Spool FX-150

I will be updating this thread as more options become available. If I left anything out or you feel like I should add something, feel free to post or shoot me a private message. I'll be happy to add more information.

Latest Update: 02/06/2020 @ 5:47PM
- Dorch pumps are now fully Plug N Play, MHD/BM3 both have flash options.
- Fixed link to Spool HPFP (Accidently linked to N55 pump, fixed now)

In regards to Spool I got the following info.

we will be releasing in about a month but we can get you a unit pre release if you like. The FX-150 which is 50% over stock would be $1400 and the FX-180 which is 78% over stock would be $2000. There is a 2 week lead time for pre release orders.

I have a XDI pump on the way.
Will see how it goes with a Pure Stage 2 on e85.

Those are some impressive numbers. I look forward to seeing results from people who get them.

As for your XDI order, be sure to keep us updated on it. I personally purchased the DE Stage 1 pump to use for my Pure 800 turbo I just ordered.

Great idea for this thread.

I think it's important to include that the pressure relief valve (pressure regulator) for HDP6 is fixed at 400 bar and although the tuning of the fuel quantity control valve via PWM signal can target 200 bar (2900 PSI) there may be instances where pressure far exceeds that, potentially over 5800 PSI.

Our HDEV 5.2 injectors are designed for 200 bar

Both XDI-35 and Dorch Stage 1 have a 2900 PSI design and matched pressure relief valve

Subscribed - great thread!

[kern417]

I have a TU pump on the way. Paid $650 for it used on eBay.de. Look out for used pumps from wrecked vehicles and it becomes a much better value.

Draw a straight line for me on this--what are the potential results of an excessive pressure event and what conditions would likely trigger it? (tracking the car, extended WOT pulls, long highway cruising, etc?)

Since these are actuated by the crankshaft, I think the controller's role can't be over-emphasized especially at high RPM. If it can't relieve the pressure, the injectors are eventually toast.
I am eyeing XDI since they have the experience in this space but probably the most expensive.

Thread Updated: Added possible concerns/drawbacks section under the B58TU HPFP.

They are. I was told their new pump is just north of $1600 when I called Frank last night.

BMW/Bosch changed the fuel injector design for the B58 TU with different materials, coatings, seat size (nozzles) and injection patterns to accommodate the higher design pressures. Apart from potential physical damage to the injector the distribution of fuel into the combustion chamber would not be optimized, potentially fuel washing cylinder walls etc

As far as under what conditions it may occur, I've included a couple of data log links from from drag strip runs with stock HPFP and E30 mix on a MHD Stage 2 95_102 map. In these two runs rail pressure seems to spike around WOT gear changes, possibly due to there being a boost spike with our EWG/lack of diverter valve? As the stock pump has what appears to be a 250 bar relief valve pressure can get up to about 3500 PSI.

So just confirm in plain English, the Dorch and xdi pumps should not require upgrading anything else because of the relief valve matching stock pump. So this may make them better options?

Correct. I also think there's little benefit in upgrading the pump unless you're also upgrading the turbo

I think that's correct, from what I understand you might be able to squeeze out a little more power with a custom tune but not worth it unless you upgrade the turbo.

Unless you disliked mixing fuels and wanted to run straight e85.

This isn't necessarily true, upgrading the HPFP would be beneficial even on stock turbo. I was capped around 420-430whp (guessing based on my track times and cars I raced in mexico) on my custom E30 map. I was capped at pretty low boost (16-17psi) until 5000RPM's when the HPFP could provide more fuel. I decided to throw a meth kit on and I immediately saw and felt a big difference. My track times went from 7.6-7.7 to consistent 7.4's.

Even with the meth my rail pressure was still dipping quite a bit, the car still has a lot more potential, I just need the fueling to support it. As far as I know, there are a couple people maxing their stock turbos around 500whp with upgraded HPFP/Supplemental fueling.

[OzBMR]

It's a big investment for the extra hp from the stock turbo though. Cost of the pump, install, plus custom tune.

[SC_B5X]

Indeed. Still a pretty decent bump in power for relatively low cost ($1000 for DE Stage 1/TU Pump + $100 for install give or take + $500 for tune give or take) for people who aren't ready to go full send with a turbo. I was doing this route before I saw Pure's Black Friday Sale on their Pure 800.

It's actually a better investment than meth considering a decent meth setup will run you north of $700, then you also have to maintain it. Compared to a HPFP you will constantly need maintenance (filling tank, cleaning nozzles/filter every so often, etc), where the HPFP is just install it and you can forget it. The main reason I got it was so I could push more power on my stock turbo and also ditch the meth because it's a pain in the arse.

Everyone has different needs and preferences, that is just my personal take on the matter.

Checked my camfollower today after running the b58tu pump for a couple of months at 485whp with e30,
The camfollower looks fine, no damage. I think the damage this guy had was caused by a install error.
I can confirm I never had a single problem with the pump, it always performed like expected.

The b58tu pump works at around 3200psi taper to 2900psi. This is on e30. It just follows the target provided by the ecu. It never goes higher.

I also view it as staging for the eventual turbo upgrade. Max the stock turbo now by adding additional fueling capability, then I'm ready for the turbo upgrade later.
