This is who people need to see for B58 quality content. Well done sir!
Thank you for the making of this video I needed some guidance when it came to this
Thank you for the quality content you provide!
Amazing vid, learnt loads, thank you for these in depth vids man!
Thanks again for another in depth, straight to the facts video my good friend ❤️ eagerly waiting for the next one
Excellent video. Very informative. Thanks for producing it!
Well spoken with great details 🔥🔥🚀🚀🚀
Thank you so much for this information... I've been searching like crazy for this info about stock Tü and aftermarket hpfp.. thank you again for sharing this video with us.
Running almost a year on dorch stg2
Great products for bigger turbo
Awesome vid, thanks!
You just helped me answer my question on buying an HPFP. My B58TU handles more than I thought given I will keep the stock turbo. My stage 2 with a catted downpipe, updated air intake, amd MHD should be ok. Now I have to think about the intercooler...
Awesome information.. Very well done. You helped me with my decision for sure.. Thanks a bunch
I really like your videos very informative
Man you are everywhere… I was in the forums yesterday and you popped up, then less than a day later I’m poking around on TH-cam and you’re the first video that pops up… you’re the BMW guru that’s crazy. While I have you here; I want to upgrade a turbo on a m240i, I’m mainly just looking for like stock+, nothing crazy, I’m not trying to wear down my cars components nor am I trying to upgrade every single little part, I feel like you start running into issues doing that. I just want to set it and forget it. Once I’m done I’m done, I don’t want to tinker, I want to have it installed, get it tuned and that be it. I’d like to be around 550hp on 93. I’m okay with adding a fuel pump, a down pipe, and a tune. What is the best option for me? Which is the least fuss and most reliable/OEM feeling of the bunch? Pure 800/850? I would go top mount if that was the best route, money isn’t really the limiting factor, it’s more so I want to remain more stock than not stock. If you say top mount with DP and fuel pump best suits my needs, that’s okay. If you could recommend the FP and DP and tune to go along with it that would be great as well. Thanks Guru!
Great video
Thank you so much for this video. I watched it a while back but am still learning. I came back today and watched it again and know everything you are talking about. I have a 540 and I'll buy the TU pump. I'm not upgrading my turbo and am fine w/ no more than 550hp, but will go w/ a tune, High flow down pipe, high flow intake and this TU pump.... we'll see what that gives me. I'll also buy new Coil packs and new plugs. If anyone here has some recommendations/lessons learned... I'd really - really, appreciate your input.
You should definitely tie it all together with a custome tune
Dunno if it's worth mentioning, but these are just off the shelf GM LT1 (stage1) and LT4 (stage2) pumps. Lingenfelter makes a big bore (+~10% flow over the LT4) version of this pump that should be straight drop-in for either of these kits once you move the lash cap over and rotate the connector. Basically any upgrade made for the GM LTx motors should be direct fit here with Dorch's adapter plate, lash cap, and plumbing, which is pretty cool.
I believe Kevin mentioned this in a previous video explaining why there will probably not be any upgrades for the B58 TU HPFP, as there are no other cars on the market that support >5000 psi currently.
One of these companies could probably talk to Stanadyne (the company that designs/makes these pumps) and see if there are any options for higher pressure relief valves. They primarily do diesel pumps, so they're definitely familiar with higher pressure applications, and they state that their pumps are configurable, though there are probably some MOQ hurdles for aftermarket communities there...
The new Z06 runs at 5000psi....but the hpfp design is very different. We'll see.
Just a heads up. I emailed Dorch about just swapping the HPFP alone and keeping the stage 1 lines and rail (when changing to a stage 2 HPFP) they said I should change all the lines and rails.
you think stage 1 dorch will be fine with a hybrid turbo like Pure Stage 2 and some E30? Goal is to just be 500-550Whp!
Thanks and we’ll done on great content.
Any word at all on a hpfp for the TU engines? I saw your video explains why it’s unlikely but asking anyway.
Not yet but I'm keeping my eye out for any updates
what problems did you run into to decide a fuel pump?
All I have to do is get the tu to run e30 or is there other upgrades needed
Has anyone had a rattle from the b58 tu fuel pump, mine is very noisy ticking
Hi,
I want to get hybrid turbo and get 600crank on 99 ron fuel. I have supra, so allready tu pump but is it enough for this power? What about single turbo and power like 700 crank on pump fuel 99 ron? I don’t want to run E blend as I don’t have where to store it in Europe and we don’t have ethanol at the peteol station.
Thanks a lot
Thanks for another informative video, I had a question that maybe you'll have some insight on. I only have 92Oct local to me so I run MHD STG2 on the 91 tune but was curious to run the 93 tune, is it close enough to run no problem? would throwing octane booster in every tank make it safe? Or is the tune so potentially similar it doesn't matter? Thanks ahead if you have any insight!
I wouldn't run the 93 tune with 92 or octane booster. If you want more power then i recommend a bigger turbo and the TU pump.
@@kern417 Okay noted, Thank you for the reply!
Do not ever run a tune that is designed for a higher octane that is in the fuel tank. That risks catastrophic damage to your expensive engine.
Plus there is no upside to doing so. There is very little gain to be had from going from a 91 tune to a 93 tune. Whatever small gain to be had depends on the 93 fuel in the tank to be high quality.
A 91 tune with high quality 91 or 92 octane in the tank with run smoother and feel more powerful than a 93 tune with weak/poor 93 octane that is forced to do excessive timing adjustments to protect the engine from poor quality fuel.
Hope this helps!
@@johnungvarsky8875 It does thank you!
It’s better to have more than less in a scenario like that.
Hey man what turbo and hpfp you recommend for a 2018 x3 m40i. I have bootmod3, downpipe and chargepipe. Got crappy gas out here. 91oct pretty much all there is
Tu pump is enough
Hi @kern417 massive fan here from the UK. I need to ask. I'm currently running BM3 stage 2+ on my gen 1 b58 M240i with the TU HPFP and loving it. However I would like to flash back to stock for the winter months my question is can I keep the TU HPFP on the car and just select OEM in the map configuration settings so the car thinks the standard pumps on, or would I need to install the stock pump? Cheers, appreciate your continued help. J
Yes you can
@@kern417 thankyou bro 🍻
Hey kern, this video is old but just want to know I have the dorch stage 1 hpfp and want to go flowmax tubo 2.5v+ . Would the dorch stage 1 support a e50 blend or do I need to upgrade? Or which blend would be best with the upgraded turbo
sure. usually e30-e50.
@kern417 Out of curiosity since i dont really know how to flows work i know you put it in the video but to dumb it down for me lol, what mix is achievable with the TU? surely it isnt full e right or is it?
Yes
@kern417 if running stock turbo b58 with stg2+ tune from MG flasher E40 map is there any power benefit from running dorch2 instead of TU pump? Dorch2 makes more flow so power will be bigger with dorch2 or will be the same as with tu pump on E40 stg2+ map ?
No difference
Can I us e a b58 first gen hpfp on a 2013 bmw 135i n55 engine?
One question, Can I go full e85 or e85 mix with premium and upgrade my hpfp to Dorch stg 1? I have stock turbo and cts intake with mhd tune on my b58.
Yes
Good video brother!! I have a cold air intake and high flow catted downpipe on the way for my gen 1 b58 (18’ 540i). Once I install the CAI and DP I want to go stage 1. Do you think I’ll be good w the TU/Supra hpfp?? Thank man!!
You don't need a downpipe or hpfp for stage 1
@@kern417 should I go straight to stage 2 since I already bought the DP? If so am I ok w the TU hpfp?
@@alroza1 pick the tune that you want to run then build your car around that. All of the tunes specify what parts are necessary.
Looking to do a TU pump with PI meth on a pure 800. How much do you think ill make? I think ill go with a E30 blend
You can make 600-700 depending on how hard you push it
Hey Kern, I'm sorry if this is a dumb question. If we were to run a TU pump on our cars would we need a custom tune to run 91 octane, or could we simply use the Stage 2 91 OTS bm3 tune? There isn't a selection for the TU pump in the tune config, only Dorch and Spool. I'm asking because where I'm at ethanol is hard to come by, but I'm moving somewhere where it is more common. I figure I'd install it and run it on 91 and then switch to an E30 tune, but there is no OTS Stage 2+ 91 octane tune. Thanks!!!
TU pump works just like the stock pump so no custom settings are needed.
@@kern417 thanks kern!!
would I benefit at all from running a TU pump if I am only intake+jb4 (map3)? I get the occasional lean fuel code
You can add more boost/ethanol with a TU pump but i believe you need a backend flash to take advantage of it
Besides price, is there any reason to go with dorch stage 1 vs stage 2? Like fuel economy? I plan on eventually going bigger turbo but not for a while, would I benefit from sticking with stage 1 for now until going bigger turbo and then go with stage 2?
Nope just price. If you don't need the extra flow then there's no reason to go stage 2.
@@kern417 thanks for the info. One last question: if I'm using MHD and I install a dorch HPFP will I be required to stick to 93 octane maps or higher? Having the ability to use 91 octane maps is very helpful for long road trips where high quality gas is hard to find
You should be able to check the dorch option in any map. Double check the settings
@kern417 so I installed the TU pump, and ran into the issue of the fuel lines not lining up seamlessly with the rail and pump etc. I too had to man handle the rails into place. I’m kind of concerned about leakage though, the flared ends are off to the side, and I tightened tf out of them. Was leaking a concern for you? I drove it, got on it a little and brought it back to the garage. I don’t see any leaking. But I’m curious as to how it’s going to handle on an e40 map with higher pressure. Thoughts?
Maps don't run higher pressure. To make it easier you can loosen the pump, line up the hardlines, then tighten it down again.
@@kern417 good to know, I’ll do that.
@@kern417 will there be any way to tell if there’s an issue with the alignments through data logging? Mine were pretty off, even backing out the pump and redoing it. It’s got me a little worried ngl.
If you tightened it then it's fine.
@@kern417 I appreciate the response, and I apologize for the million questions. Learning as I go, and you’ve been extremely helpful. I got your shirt on today for the test runs, it’s going to bring me luck.😂
Stage 2.5 now.
I just had dorch 2 installed with the base map from mhd to run while I wait for my custom tune. That should be okay with no issues right ?
Yes, it’s fine. A lot of people run a upgraded HPFP with a MHD OTS / Base map
Yes
Have u upgraded Tu pump ? Did u get any codes or check engine light ?
If you’ve installed your DE stg2 already, did you get your nut that couples the rail and pump together to thread all the way on? Other two go all the way down by hand when I installed how the manual says but the one that goes to the pump won’t go all the way down. Is that normal or should I keep messing with the alignment?
I posted a DIY last week. Check it out. It's normal. As long as it threads on smoothly (no cross threading) it's good.
@@kern417 I’ll check it out. I followed along with kies and noclutch and couldn’t really make that out
@@kaboom1717 I think even if you just look at the thumbnail I used for my video, you can see it's only threaded about halfway on.
Can you use the TU pump without ethanol ? Just on stock turbo stage 2 93 octane?
Yes
Can I use the stock fuel pump with my BM3 stage 2 tune? Everything is stock on my G30 except the downpipe.
yes
thoughts on going with a dorche stage 2 on a stock gen1 b58 engine/turbo?
works great
How much power will the stage 1 support? Do you think it can support 675whp or even closer to 700whp on a e40-5-0 mix?
No. It will support around 600-620 on E30. Higher ethanol content will limit how much power it can support.
@@kern417 is that the most I can get out the pump period? Or you think I can make more power on race gas?
Yes race gas will make more power. Sorry I'm so used to people jumping straight to ethanol I didn't think to mention that
@B58 it's the absolute limit. 550 is safer. And well within it's capabilities
@@kern417 so if I want 650 wheel horsepower with upgraded turbos and full e85 I need dorshe stage 2 right ?? Will it be able to support full e85 ?
Is it risky for the cam to run aftermarket pumps on a gen 1 b58? I have a downpipe and tune and i just want to prevent any catastrophic failures. I also like to run a bm3 standard 91 octane tune to make about 400 whp
No it is not
I’d say if you were worried about it to just replace the cam follower when you upgrade the fuel pump. I replaced my follower and gasket when I installed mine just for a piece of mind. The old follower had almost 50k miles on it and still looked pretty good.
What’s the max E blend I can run with the flex fuel kit from BM3 on the stock Gen 1 pump?
Do you think I could run full e85 with the tu pump on Mhd stage 2 hpfp ?
Also wondering this. I'm not going higher than MHD Stage2 but do want to run full E85
Ever since I changed out to the TU fuel pump, I can not get my tune to give me the extreme burbles. I even flashed it and set the aggression to 12 at 1.5, 1.7, 2.0, and 2.5.... I can't get the cracking and pops like I used to ( Stage 2 - 93 Oc.)
Bootmos3..... HELP Please
Why would you have the burbless anyway? Sounds childisch and its annoying.
And its not great for the car either.
Do you plan on keeping your old pumps, or are they already gone?
The TU pump is sold. I may go back to stock pump in the future if I add port injection
I have a 2019 540xi which pump does my car come with does the b58 tu come with the TU pump or no?
you have a gen 1
if you are on stock turbo, could you skip hpfp upgrade and get port injection? just a random idea i had. not sure if it would work. any thoughts or feedback? Thank you!
you could but it over-complicates things for most setups. i have port on my stock turbo car because i wanted to try it.
So i have gen 1 its a 2019 540xi but its gen 1 pump so if i upgrade to dorch stage 2 do i need to upgrade anything else like injectors? Amd what turbo should i upgrade to? Im stage 2 MHD ots and catless plus intake and charge pipe
You don't need to upgrade anything other than the fuel pump itself. There are a lot of good turbo options so it more depends on your budget and goals.
I do not plan on going big turbo I’m just wanna run the stage 2+ tune from bootmod3 should I by the tu bump or the dorch stage 1 I have Hurd story’s in forums of the tu pump eating the cam or blowing a injector have you hurd if any of theses issues and what would you recommend
TU is fine

Yo boss , I got a tu pump . I’m planning to make atleast high 500s / 600 whp . Would I be able to achieve that ?
Yes. Watch the video
Hey Kern ik this videos old but I was looking into getting the mhd flex fuel kit but since I live in cali we’re limited to 91, would I see any gains by getting the tu pump over stock if i’m only gonna be running 91 most of the time with e30 used on weekends?
I’m assuming that while on 91 there would be no difference but when i’m running e30 there would be, just want to make sure it’s not a waste of money to buy a tu pump
yes that's right. not much gains on 91 but noticeable gains on e30. however mhd doesn't have a 91 stage 2 hpfp tune.
@@kern417 Sounds good thank you for your help, ill likely stick with the stock fuel pump since there isn’t a stage 2+ 91 tune. Is there any risks involved or maintenance I should do before running an e30 tune on stock hpfp if i got a flex fuel kit, i’m at 63k miles and don’t wanna mess anything up.
nothing special just keep up with regular maintenance and run logs every once in a while

Can i run TU pump on Stage 2 91(ACN) ? Or would i need to go to Stage 2+ ?
Yes
Have people had any problems with TU pump on the gen 1 b58
No
According to several websites, the TU pump should support up to 575 - 600 HP on the crank. I'm currently running stage 2+ with the TU pump, and planning to go for a hybrid turbo at around 550 hp crank (RON 98 fuel only). The TU pump should be sufficient for this power goal? The given max power numbers for TU seem a bit optimistic.
They do between 530-550 and some dyno’s just giving higher numbers
Im same like u.Stage 2 +.Did u upgrade to pure 800 turbo and how many hp u got?
I had to postpone the turbo upgrade due to a leaking rear differential (too many launches wasted the seal). Going to replace the rear diff by a OS Giken LSD first. But I got X-Drive, getting the RWD diff installed but need some modifications in order to get it fitted properly. Hoping to get the turbo upgrade done mid 2024.

Based on your b58 tuning guide video, ive decided to go stick with a stage 2+\2.5 on my 2018 440i. If im looking to tune with MHD and run a VRSF catless downpipe, would i even need the dorch stage 1? Or could i get away with the TU?
