This is who people need to see for B58 quality content. Well done sir!

[@KG-yy3wy]

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.

[@borderwave2]

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.

[@KG-yy3wy]

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...

[@kern417]

The new Z06 runs at 5000psi....but the hpfp design is very different. We'll see.

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 KZbin 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!

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.

[@markvanderwardt3345]

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.

[@chiel-]

They do between 530-550 and some dyno’s just giving higher numbers

[@HRaychin]

Im same like u.Stage 2 +.Did u upgrade to pure 800 turbo and how many hp u got?

[@markvanderwardt3345]

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.

Hey kern I’m looking at a hpfp I’m planning on going 6466 turbo in a year or so so would it be smart to get a hpfp that can run pure e85 as I plan to have a pure e85 tune but while I’m stock turbo just don’t go over e30/ e50? I was looking at dorch stage 2 and it’s a lot more money then precision race works stage 3 that’s $899 while dorch stage 2 is like 1300$ but both can run e85 so what do you think would be better. Or do I just buy tu pump while in stock turbo and don’t buy bigger hpfp till I actually run the turbo upgrade

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!

[@kern417]

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.

[@kodiegarcia530]

@@kern417 Okay noted, Thank you for the reply!

[@johnungvarsky8875]

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!

No. It will support around 600-620 on E30. Higher ethanol content will limit how much power it can support.

[@willm2624]

@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?

[@kern417]

Maps don't run higher pressure. To make it easier you can loosen the pump, line up the hardlines, then tighten it down again.

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!!!

Hi guys can I use the HPFP TU for my first gen b58 m140i? I'm running only MHD / XHP stage 1 and was looking for a cheap upgrade.

Yes.

Yes

How about e50 instead ? Or do I need stage 2

[@D1Calderon]

If staying stock turbo, would you go TU pump or Stage 1? Planning on stage 2 tune and maybe e-30 mix once a Gas ⛽️ station comes near by.

[@kern417]

Like the video said, TU and stage one both are limited around the same.

On stock turbo, what’s the max I would need for stage 2+ tune on 91 octane? Catless+intake. I’m thinking TU would be plenty to max out the stock turbo?

TU is all you need for Stage 2+.

anybody has information about the Dorch or Fuel IT stage 2 pump, what brand or source these are? Because I do not believe, these are made by the tuners it self... I am sure only the install hardware is custom. I would be very thankful for this information..🤗 Thanks in advance!
