One of the only platforms that has so many stock components that don’t need to be upgraded

[@STAyTHIrstyMyFREind]

This is a really great video kern! Just what i needed 🙏🏾🔥

[@TheSlayin]

Always quality content, Kevin! I've watched every video you drop since I got into my B58 in May!

[@universalg_]

Perfect intro on what you might need for the big turbo upgrade. Thanks for your opinion

[@F22_Angel]

Yes! Please do the tire info video!

[@noeggarcia19]

This is great! I would love to see more of you running your build against other cars as I don't see much footage of the 4XXi competing

[@kern417]

I'll definitely try to get it out more. I mess around alot but everything isn't caught on camera.

[@amorgator1345]

Another excellent informative video, thanks! Totally agree on upgrading the tires. I don't like the ride on the run-flats so I was pleasantly surprised to find that I could stuff wide rear tires on the 440i (285/30/20 Goodyear F1 Supercar 3 on 10" rims). And using Hawk DTC pads at the track offer lots of confidence in heavy high speed braking.

Perfect timing. No pun intended

[@f36_garage71]

Just the sort of video I need as I'm upping the power in my 440i! Currently on BM3 stage 2 but only mechanical mod is a high flow downpipe. Guess I'm in the safe margin, but definitely aim to go further

[@cameronrussell9362]

BM3 has a update to the Stage 2 map. Have you flashed it yet? My car has the same Mods and holy shit it's fast.

[@f36_garage71]

@@cameronrussell9362 I just heard about it so charging up my car battery now in preparation. Does it add more hp than previous stage 2 map? Looking forward to get mine dyno'ed again. With just downpipe and mppsk it was 393bhp

[@solidsnake7167]

Same - I have catless DP, AWE touring mid and axle, DME tune and tranny tune. I thought around 480-500hp was enough (and tbh it IS) but I want MOARRRRRR POWERRRR. Got quote 6500 for stage 2 turbo upgrade, custom tune etc. and f it - I’m gnna do it, and just have a gd batmobile

[@micr75i]

great content, I really enjoy listening to you talk about BMWs :) question, have you heard anything about e-turbos? Volvo is installing them on their mild-hybrid cars and apparently they are amazing. I am talking about having an electric motor strapped to the turbo to eliminate lag and produce a lot of torque down low. Thanks!

[@kern417]

Yep. It's also on the new c63s

[@noodle9851]

The fact you can make 9001 horsepower with just a few mods is crazy😅

[@F30__Zay]

Hey quick question, I want to make around 650whp and hit around low 10s in my gen 1 b58 I’m stuck between the new cast pure 850 or a big boost 6466 I understand the hybrid turbo would get me to those goals but I don’t wanna potentially break anything else by having to max out that turbo

[@Duncan94]

9:30 - With regards to upgrading downpipes, are you referring to some people making the stock downpipe work or catted DPs in general. Is pushing 550-600 even too much for 200/100 cell sports cats?

[@kern417]

including high flow downpipes. unfortunately they can still fail when pushing higher power levels despite being less restrictive than the stock downpipe.

[@dromo32]

Do you recommend upgrade axels for the m340i xdrive? I have around 850 whp and I was entertaining axels, but I legit cannot find any upgraded aftermarket ones.

[@edoardot1374]

Hi, thanks for your informative videos! One question, why do you think some b58 engines are failing? Are there weak components from factory like rod bearings? Thank you

[@kern417]

[@edoardot1374]

@@kern417 Happy to see you made a video about this topic (rod bearings)!

[@ian.gomez_]

with regards to the new bm3 tunes (stage 2+ e30 and e50) I'm a little weary about how they were able to push the original stage 2+ e30 from 450-470whp to over 500whp and how safe it is on a stock turbo as well as how safe the e50 tune is for a stock turbo FBO build as well? (I'm currently running the TU pump)

[@kern417]

You have to run logs to see how it works for you. The logs I've seen so far look good.

[@XandrMotorsports]

Will 4,500cc injectors suffice for hitting 9000whp? I feel like 6,000cc just isn’t for me.

[@kern417]

I stopped reading after "4500cc". Whatever you're asking, the answer is yes. 100%, yes.

[@none8258]

@@kern417 I think he's messing with you because around 4:17, the text says 9001HP, rather than the 900 you meant ;)

[@kern417]

This is hilarious because i forgot i even put that in there 😅 power is over 9000 so 9001 seemed accurate

How much hp and torque has ur setup? It looks like a beast😤

[@tighesimon]

Question for the group: I have a g20 M340i, and I plan on getting the Active Autowerke DP and a Vargas GC turbo (with a tune). Any ideas what HP and TQ I can aim for (with a non agressive tune). Are there any other bolt-on's I should look at to support this set-up? thanks all.

[@kern417]

pick your goals and then build your car around those goals.

[@b58bozy83]

quick question.. i know the dorch s2 would be better but just wondering I’m about to run pure s2 and I plan on doing full E so is the TU pump good enough or should I just go dorch?

[@kern417]

TU works you'll just be limited on power

[@LuisMoreno-rs2qk]

Question: what is the dance moves that go with the beats at the end of your vid?

[@kern417]

I might need to put something together for that 🤔

[@dangdong3832]

Do you know How to turn engine over without starting? Switch on oil pump ? Thanks kern

[@kern417]

the oil pump is mechanical. you can turn over the engine manually by putting a big box wrench on the crank pulley bolt.

[@Vindettta]

Do you have a video on what to upgrade if I’m just wanting to push 600-700whp with the stock turbo? I’m new to this b58 platform and cars in general

[@kern417]

You can't do it without nitrous.

[@Vindettta]

@@kern417 I see. So 500whp would be stock turbo range?

So for 700whp with a doc race turbo kit what would I need to upgrade

[@kern417]

Port injection and clutch/transmission depending on how much torque you want

[@trapgodnah9022]

Is there any benefit to LPFP upgrade on DS2, i heard it helps flow ethanol better

[@kern417]

With just ds2 it's not typically needed

[@trapgodnah9022]

[@williambadger3556]

@@trapgodnah9022 tu pump flows less so I doubt it

[@trapgodnah9022]

@@williambadger3556 thats why i was thinking would a lpfp help

[@kern417]

Imagine you're trying to fill a bucket with a hole in it. The bucket is your HPFP and the hose is your LPFP. If you make the bucket bigger then you might struggle to keep it full because it's flowing too much out of the hole. That's like putting a bigger HPFP on your car. If you make the bucket smaller then you won't have any more issue keeping it full. So a smaller HPFP won't have any advantage from a bigger LPFP.

[@hassandawoud5220]

How much hp does the energy drink give and how do u install it, I’m having troubles here..

[@kern417]

Thanks for noticing. It's actually very easy and something i will cover later because everyone is so surprised by it. The car is actually a 3 cylinder but the energy drink makes it perform like a 6.
