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.

Thanks for the update! Hoping to do something similar to my F30 2018 330i :)

[@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

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.

thanks for the very informative video! i have a f30 330i and ive wondered what the upper limits are on the engine. theres so little content/info out there for the little 4 banger! i a have a jb4, catback, mst intake and ftp charge pipe, as well as lightweight forged wheels and im really happy with how peppy the car is. not pushing crazy amounts of power but i think its perfect for a daily.

[@VehicularDIY]

Thanks for watching! Toward the end of the video I cover that topic.

[@matthewthedude146]

Now this makes me excited for when the warranty for my g20 330i runs out! Over 500tq out of an unmodified 4banger is insane!

[@DjRevvz]

Thanks for the vid! The results are ridiculous and car sounds amazing. I plan on doing the same thing pretty much to my f30 330i 2018. For me to run the 330i pretty hard at the rack with reliability, what horsepower and torque do you recommend staying around (track) with the dyno and im450 turbo thats NOT going to stress the weak pistons in any way. Since I love the canyons and track I def don’t need the bigger 500 turbo. I’m just concerned with acceleration & mid power basically and suspension. With the 450 turbo upgrade, the downpipe & charge pipe, intake, and b58 HPFP would that be cold killer at the track? If not what else would you add? Thanks!

[@flippy9133]

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

[@VehicularDIY]

The logs are happy thus far. Not worried about the pistons since I'm running ethanol, it would only be the rods but they aren't the week point even on the B58s being pushed to the limit.

[@skinnyguy9985]

Awesome video ! I have a 2017 f22 230i, was wondering how would it stack up to the f30 330i power? With the mods you provided. Or would it not be compatible?

[@petrkovalev1926]

These videos are gold!❤ Really close to buying this turbo. Would I need to do something other than bolting on the turbo if I run 93 fuel. Obviously tuning but will I need to touch on fueling or internals in order to make ~450hp and 500 torque?

[@known3617]

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.

[@gregm7508]

Woke up and saw the video and thought ooohhh snap this is it😅

[@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]

The owner of IPOS said if the B58 is the modern 2JZ the B48 is the modern SR20 or 4G63.

[@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.

[@VehicularDIY]

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

[@laurentiu.panait2536]

Awesome to see somone with such ambition and dedication to a 4 cylinder BMW! I would ask you kindly to link me the connecting rods, wrist pins, piston rings and possibly con rod and main bearings that a performance B48 would use, because I have a 2009 BMW 318i with an N43 2 litre and I am researching into reinforcing bottom end, to prepare it for boost and long term endurance, might as well scoop out compatible parts from a B48, and I would love to hear from an experienced user like you.

I have added a dry high flow air intake filter for the oem box along with RaceChip GTS piggy back tune which claims +67 HP & +95 Lb torque…the last mod I did was pull the fuse for the exhaust flap to remain both open at all times rather then only one. Now I’m curious if leaving this valve open could it work against gains. Does the valve help with back pressure or anything along the lines that it’s best to leave it as is rather then open. Also is my B46 SULEV much different then a B48 ? Any info is appreciated thank you !
