I should also mention that if you have a B58TU, i.e. M340, Supra, etc, there are no HPFP upgrades available. Those cars come with the TU pump, so your only option is port injection.
Also no St1/2 Dorch?
There are no hpfp options for TU engines.
Kind of strange. Because the same TU fits on a non-TU. Will they come in the future probably?
@@Dutch79 It's not about fitment. It's about programming. The TU engine runs at a higher pressure so the aftermarket pumps for non-TU engines don't support the fuel pressures that the TU engine needs. I'm not sure that they plan on making upgraded pumps for TU engines but it's possible.
@kern417 Is port injection enough to avoid walnut blasting forever or am I dreaming? Keep up the killer B58 work. Such a resource.
Bro your channel is an absolute gold mine. Doing research for a 340 I’d like to build one day and wow, your channel has everything. 👍
Great video as always. Well explained. Lamin terms.
Great video, very informative, thank you! (One thing I would request is a bit more inflection, or a touch more energy while you speak. I was really trying hard to listen, but the sound of your voice is just very relaxed/relaxing and putting me to sleep, so just a bit more energy would really help with that. Keep them coming though, because again, very informative!)
I’m spend a lot of time starting at your engine bay. Excellent video as always
You and me both 😌
@@kern417 it has a soothing effect 😌
The b58 god has spoken
There’s 6500 languages and you chose to speak facts
Video helped a lot! Looking at PI for my N55 X3 in pursuit of maximum HP!
Thanks for the vid
THANK YOU B58 SENSEI
I have a 340 xdrive looking to go with port injection daw turbo 2.5 on e 85 so dorch stage 2 would be my to go option if I’m shooting for 650+
Hi Kern,
Congrats on your 5k subs!
Question : Running a bigger turbo and acces to 102 RON. Making 612hp on just the TU pump. Wanting more in the future. What do you recommend? Dorch stage 2 / WMI or Port meth injection? Looking for 650+
Port meth
Great content, thanks a lot! How about the "improved cleanliness" some manufacturers of WMI are claiming? Do you see this additional advantage compared to a HPFP upgrade? For my understanding, a WMI kit seems to be more value for the money… you keep IATs low, have enough additional fuel for up 600+ hp with upgrade turbo and cleaner manifolds/valves…one the other hand, it is not that easy to install, you gotta keep the tank full, doesn’t look stock, etc… what do you think? I’m not for one or the other thing, just asking/discussing with someone who’s dealt a lot with these topics obviously. Thanks!
Keeping the system simple with an HPFP upgrade is the best solution until you absolutely need auxiliary fuel injection. I'll be posting a video about WMI this Friday.
Great video but even better bug zapper for these nasty cicadas lol.
Dont know whether you can get it in the US but I've got one called "the executioner pro" its like the port injected big turbo b58 pf the big zapper world but without any safety meshes and super powerful so keep it away from kids lol
That bug zapper though...🤣
Hi Kern! In the comments of Remnant Performance i read the fuel system is already maxed out (supra), not the octane. With big turbos and 93 fuel, bigger hpfp (not on the market yet) can be usefully?
What are your thoughts? thanks!

"Well in preliminary testing we were able to confirm the the 65 OMEGA spools faster than a Pure800 and it produced so much power that we maxed out the factory fuel system on just 18psi on 93 octane haha. We have to add our Gamma Intake Manifold & Port Injection system to find the limits of the 65 OMEGA on 93 octane. The 65 OMEGA should be capable of producing closer to 200whp more than a Pure800/850"
Lol love the bug zapper
How much extra power does port wmi add once it is mapped in?
I clicked the like button before the video even started bruh
Your clicker must run E30
Hey Kern, thanks for the helpful videos, as always! I have a DAW turbo but haven't gotten a hpfp, yet. Would a TU pump be enough to hit 500-550 HP on 91?
500 will be about the limit on 91. It's usually somewhere between 450-480.
not on 91 you need higher octane
I have a 1st gen b58 and I only have 93 available in my area, would u recommend getting port meth injection only or port meth+ hpfp pump and planning on a pure800 or vargas gc+
Port meth is all you need
I am targeting 700hp+, I ordered a pure800 stage 2, I already have a dorch stage 2 HPFP on the car and also ordered a port injection kit, I know u mentioned u don’t really need both, but I should easily reach my goal with that set up? With E85 ?
Yes
Hello brother it’s great information
I have a question what is Sequential Port Injector unit work well with bootmo3 You
recommended my set up is
A90 supra 2020 2 port with vargas Gc+ turbo kit upgrade
full AWE exhaust system
injen intake system
cts 4.5 down pipe
Bootmod3 ots Stage 2 93 octane map
any idea
Motiv Reflex
I know mentioned you recommend running stage 1 or 2 hpfp for 600-650hp goals, but is it safe to run tu hpfp on b58 with catless downpipe, intake, and Bm3 e30 tune? Wondering if there will be any head space at all or if I’ll be maxing out at that point. I also noticed for e50 tune in Bm3 app,there is a tu hpfp configuration. After watching this video I’m wondering if that is safe or recommended to do.
stage 2+ ots maps are designed for the tu hpfp.
What’s up kern,
Hope you have been doing well.
I have a 2020 m340i and I plan on getting customed tuned by pq performance with an intake, charge pipe, Ngk spark plugs, and a transmission tune. Would I be able to run the port injection comfortably or will I need to upgrade my turbo/transmission?
You can if you want but it won't make a huge difference on stock turbo.
What if you plan on only running 91 octane? What kind of power can you make max with the stock turbo?
Maybe 420 max
Do you plan on going 700hp+ im very interested in the doc racing kit, would like to see its limits pushed
Follow their Instagram. they posted several dynos already.
So if I get a upgraded instant manifold
I don’t need PI
love your videos, very knowledgeable about the platform...How do you feel about the DAW Flowmax + ? I'm in-between This Or the Pure800 looking for 550-600 WHP
It shouldn't be a good quality turbo but time will tell
@@kern417 would you reccomend the pure800 instead? looking for an easy install and reliability
You can't go wrong with either based on the results I've seen so far
Do the flowmax manufacturer have an Ig or UA-cam?
@@PoorlyUtilized search for dynamic Autowerx. They have an Instagram but it's not very active. They post a lot of Facebook though.
so if i run a TU pump and port injection i can run straight e85 without issues? (with the correct tune ofc)
Sure
Who makes a good meth port injection for the b58?
I have pure 800 and TU pump. Gen 1 b58. Or should I run a e40 mix?
e50
Is there any point me upgrading the hpfp to the tu version on an m240i on MHD stage 2 if I only have access to 99ron? As MHD don’t offer a stage 2 (+) for 99 and only 102 Ron or e40?
It will help with a bigger turbo but not for regular stage 2 maps on stock turbo
@@kern417 is it possible or worth it to buy bio ethanol off eBay and add to a full tank of 99 Ron and then run an e40 map? Or does it have to be injected with a kit in the boot?
@@b16dans yes a lot of people buy e98 online and use that for an ethanol mix tune
What're your thoughts on the dynamic autowerx upgrade turbo?
It looks pretty good but time will tell
So i have a 17 540i & im stage 2+ right now with tu pump on bm3 running e50. I plan on upgrading to pure 800 . Do i have to get a new hpfp or will i be good enough with port injection? Im trying to make about 600-650whp
I recommend a bigger hpfp for 600-650.
If I have only 91 octane available but do have access to e85 what would recommend as far fueling to hit that sweet spot
e30-e50
Great video, at what HP should we be upgrading the LPFP or is it only needed if your running Full e85?
It depends on your E content and tune, but it is typically above 650-700whp.
My goal is 700ish. I have a bigboost gtx1000 kit with a gtx3584rs gen 2. And precision raceworks port injection? Is that all I need to reach my goal?
Yes
I am trying to better understand which route should I go.. Port injection or direct injection. I am using my car for daily and spirited driving in the south and plan on upgrading turbo soon
stick with DIY unless PI is aboslutely necessary for your goals. most people can get away with just an upgraded hpfp to meet all their needs
Where can I get the yellow thing on the top right?
Harbor freight my friend
What about the lpfp will that need upgrading as well?
Typically you need it above ~650whp
What up kern currently sitting at custom trans tune, tu pump custom e40 tune stock turbo, I’m looking forward to purchasing a ultra flow r with a dorch stage 2.5 will that be enough to get 700whp on e with this setup? And obv upgrading lpfp
you can probably get there on an ethanol mix (e40-50ish) and a perfectly dialed in tune. you will either need port injection or upgraded injectors + exhaust cam to reach 700whp on full e85.
@@kern417 so let’s say I keep tu and go with a port injection plate what difference it would make to combine the port injection with the dorch 2.5?
So you’re telling me I don’t need port injection to make 600-700 whp just stage 1/2 hpfp and a bigger turbo? 🤔
Recommendations/links for a stage 1 or 2 hpfp?
Search Kies Motorsports. They have both dorch stage 1 and dorch stage 2.
www.kiesmotorsports.com?aff=28
I’m running 91 octane and plan on keeping my stock turbo with a tune and intake/downpipe. Should I get a TU or stock is good enough?
Stock is good enough
TU long time ego lol
Can you run a e50 blend with a stage 1 hpfp
Yes you just need a custom tune
can i run 93 and switch to e85 whenever with a stage 2 pump
I may be wrong but it would be a flex fuel sensor kit
Just realized I got a shoutout 💪🏼
🤘🏾
If you just upgrade the HPF alone, do you need a retune?
TU pump, no
Dorch/Spool, yes
Ok so it's state 1 or stage 2 HPFP for me.
Question here, with an upgraded HPFP or a PI is there any noticeable increase in fuel consumption. It would be kind of logic but who knows. You😜 cause for a Dayly it would be a downside of a mod like that.
Better fueling Worse consumption🤔
It uses more fuel when it requires it. If you're just driving around town then it'll be pretty much the same
@@kern417 so best of both world, daily and performance wow. Thank you Master YODA58, Buru58
At what HP do we need to rebuild the engine?
700+
@@kern417 perfect, thanks man!
Can you run full e85 on dorch stage 1 or 2?
Sure
@@kern417 what’s the max E mix for the Tu pump
@@dcharles9903 ua-cam.com/video/2YNlGYwAZM8/v-deo.html
If I upgrade my HPFP can I still rn 91oct or do I have to run E85 fuel?
You can run any fuel you want
@@kern417 21 m340 can’t have an
Upgraded hpfp though?
None are available
no you can run 91 and 85
Bro, that damn engine bay. Jk bro💪💪💪
Man up and do both ya panzy
🥲
Hiii maf off?
