We Set a World Record In BMW B48 4-Cylinder Power!

In this episode, we've achieved something truly spectacular. We've set a new world record in BMW B48 4-Cylinder power! Join us as we take you behind the scenes of this incredible journey, from the initial spark of the idea to the moment we revved our way into the history books.

Bro I cant imagine running into you in my stage 2 340i (6 speed) and getting gapped by 330i. Lol what a beautiful thing!

[@carcrazyguysa4059]

Modern BMW engines have so much potential I am just wondering what reliability will be like in the future.

[@tlcj3838]

These B series are potentially the best design yet. Especially being a solid deck block with a block cradle. I have a 2021 430i msport. It has the B46TU. Stock at the moment its pushing 20-24psi boost. Im i highly considering this turbo package once my warranty is up

[@indomieforlife]

@@tlcj3838 i do agree that the b series are the best modern bmw engines in terms of reliability and tuning by design, but everything around the engine itself are something that we're yet to see in terms of longetivity and obviously reliability since they're relatively new 👍👍

[@tlcj3838]

@@indomieforlife I am currently at approximately 48k miles on mine. Still stock other than Dinan axle back exhaust. In eco pro if I hypermile it I can get 43-47mpg depending on wind and she’s seen 161+mph somewhere in Mexico lol. Will be doing Dinan Intake and a charge pipe upgrade to help with the longevity since the factory charge pipe is plastic. Supposedly they beefed up the plastic charge pipe.

[@grein545]

@@indomieforlifeyeah so far emerging b48 issues seem to be related to rubber/plastic external cooling components failing with age and heat cycling. Plastic oil filter housing cracking, certain coolant houses also failing. The internals seem solid. Seems pretty typical for BMW based on my readings.

Any B46/48 gurus around? Got a 330 stage 2 BM3 with custom exhaust but having weird codes but cars running fine

Thing I love about the B48 is the space to work on. The turbo conversion from your last video looks so much easier than a N54 335i. great job man! keen to see update videos in the future

Thanks, I’ll go into details like how we figured out how to adapt the software on the motiv to work with a 4 cylinder.

[@fastboatster]

Great result! I also expected b48 to deliver, it has all the ingredients to do it. Maybe the next step is to go into the engine and do all the stuff typically done to build b58s and see where it gets you powerwise? Also, would be good to see you try swapping b58 from the f30 340i into f30/f31 328i

[@VehicularDIY]

Yeah I’m debating if I want to throw a rod and piston in and target 500 whp but 600 WTQ all day long. Would be significantly faster drag racing with that much more torque.

[@dinosoarmotorsports]

I have a 2022 230 and would love to get 350/350 HP/TQ on a 93 octane. This channel really makes this sound pretty easy.

[@PapiAndrey]

Such a cool build, i’m glad this channel is getting the recognition it deserves. We’ve all seen the run of the mill downpipe and tune B58, it’s boring now. But a B48? You never see that, it’s awesome! While i think the exhaust sounds good as is, i would love to see an unequal length turbo manifold/ header. Some S63’s sound like a boxer 4 cyl (or any unequal length exhaust 4 pot), i think if the B48 had that and also had the same active sound design from an S63 powered car like the M5, it would be even cooler. Inside it would sound like an M5 and outside would at least be reminiscent of it. The rumble and V8-esque sound. The S63’s unequal length turbo manifold has a mix of cross plane crank and flat plane crank sound. A similarly designed turbo manifold for the B48 should yield similar results

[@VehicularDIY]

Thanks! Yeah would be fun to play around with how it sounds, I’m happy it’s not raspy and when it’s under load it sounds pretty good but could use some volume.

[@AbhishekSingh-qz3fx]

​@@VehicularDIYHow is 60-100 pull, now? I bet it's much stronger. Any timings would be great. Again, you set a benchmark here, gave us a lot of hope.

[@VehicularDIY]

Yeah the 60 to 100 mph pull is much stronger and 100+ is very surprising. Seems like it's pulling much harder than you'd expect even with north of 500 HP. I plan on timing 60 to 130. I bought a Racebox mini device to do so.

[@VehicularDIY]

Yeah on a big single should be able to do 600 whp as the torque would come on later and can be dialed down.

[@Josh-qm4rb]

@@VehicularDIY Wow that is absolutely insane! God knows how much horsepower the 300hp B48 (M35i, JCW GP) can handle... They have further strengthened pistons and rods. 700 maybe?

amazing, time will tell how reliable these engines are at higher mileage, so far looks good

Very cool development, a 330i with 350 to 400whp on pumpgas would be my daily driver. I drove a 340i and a 330i back to back and the 330i felt more nimble because of less weight in the front and the 340i had x-drive (no rwd option in Europe).

[@michaelbrooks9462]

Water methanol injection on the turbo intake side should drop intake temps by a lot. And you should be able to push timing. Most kits are cheap and can use the the stock washer tank so keeping the stealth look. You should get 50 ish more HP and 90ish WTQ. But this would be crazy good with upgraded wheels and brakes and suspension. But one of these in Xdrive would really be great of the line in the 60ft and in the 8th mile but they would get passed in the high end.

Yeah luckily it has optional upgraded brakes already, adaptive m sport suspension and LSD. Wider tires in the back could help off the line.
