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.

This was all done on my 2019 BMW 330i with the B46D engine. Just like the legendary six cylinder B58, modern four cylinder BMWs have a lot of potential.

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

[carcrazyguysa]

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

[Lovedus]

Thank you sir, for this series on the B48 ! I found it extremely informative and am very grateful. Have a wonderful & prosperous year ahead!

[TheExcarlos]

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

[josephkelly]

What a beast of a little motor, running a N54 335i myself, but I like the look of one of these in my future. Thanks for being a pioneer

[perculoushoncho]

sick video, i have a 2020 330i and have been waiting for someone to jump on a sick 330i build and test it’s potential. hella encouraging to continue the build instead of swapping it 💪🏼

[Josh-qmrb]

The B48 is literally at Honda K series/4G63 strength levels!
Can we hit 550, even 600whp on the stock internals?

[fredrikmagnusson]

I love that your voice is so calm. I'm watching these as an anti anxiety remedy.

[SupraSav]

Legend, sir. Glad to see you over 100k! Well deserved

[sibbese]

Nice to see this follow up of the turbo swap, so 475hp 790Nm - @ the Wheels, but now lowered slightly. Still amazing figures. Looking forward to next one.

[Ubeans]

The technical quality of this channel never ceases to amaze me. Thank you for sharing your knowledge, DIYs, and research!

[sierramst]

This is my first time seeing one of your videos, I’m impressed with how much knowledge you have. I will definitely be following you from now on.

[AbhishekSingh-qzfx]

Finally!!! Keep posting the regular updates, on reliability or any potent issues.

[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

[Whoareyoucalling]

Crazy power! Whats your 0-60 and quarter mile times for your G20?

My map 6 JB4 G22 x drive hits 0-60 in 4.3 seconds and my best quarter mile is 11.8.

[kevinsmb]

Thank you for the content! I’ve been waiting for this update for so long!! I’m currently getting a stage 2 E85 tune on my 135iX developed and looking to get an IM450 next year

[goracebox]

Super impressive power and drivability out of this 4 cylinder! Can’t wait to tune more of these once people start getting more involved in this platform.

[souk-tv]

Is that B48 a B48B20B or B48B20A?

Other than the 2019 G20, does the 2020, 21, 22 still have the same engine / Supra pistons prior to the LCI ?

And does the 2019 or above G20 330i have a tunable gearbox?

[federicotorresbordils]

Congratulations for upgrade the B48, waiting for the next video for ECU and port injection integration with the BMW DME

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
