    • JB4 tuned BMW F32 440i B58 on meth vs. JB4 tuned 2016 Infiniti Q50 VR30DDTT on E30 ethanol blend (both automatic)

      Some JB4 on JB4 action here! BMS (Burger Tuning) JB4 boxes are very popular in the BMW world but recently they started expanded into the Infiniti market due to the new VR30DDTT 3.0 liter V6 twin turbo powerplant.


      The results early on for the Q50 models are promising with BMS Alpha tunes showing 413 wheel horsepower. Note, this is not the Red Sport version.

      The B58 turbo I6 under the hood of the 440i should be familiar to you and with a JB4 tune and some meth can put out ~450 wheel horsepower.

      Interestingly, the Infiniti pulls. They do two pulls and the result is the same with the Infiniti winning although in the second run it's a beatdown.

      Why the Infiniti wins in dominating fashion has us scratching our heads.

        Whats the surprise, Nissan has been building V6 Turbo Motors since the 90s when BMW was in turbo-denial.... it’s not until 2007 , almost 20 years later that they decided to turbocharge their in-line 6 because Japanese competition was smoking them and a NA 4or6cyl just did not cut it....

        BMW's best drivers cars have been N/A

        Ferrari's best drivers cars are almost exclusively N/A

        Porsche's purist sports car(s) - whatever you think it is/are, are almost all N/A

        BMW builds turbo cars because the EPA demanded it, just like they'll switch to electric when it demands of that as well.

        The 2002 was the first sedan that could sustain 200+KPH - 130mph comfortably with passengers, and on winding roads. It created a class of sports cars -- dipshyt.

        My friends 340i with a downpipe and small mix is... o.k. 136-138 in the 1/2. A stock C7 at the same runway does - 140. We dyno'd it with JB and the car was lean - 13.6-13.9AFR. Meth, maybe some logging (it was very early JB firmware at the time, user settings etc.) or a real flash would do wonders

        Let's see a 1/4 trap from some Q50s! Quick

        Is that terry’s shop car q50? Terry probably has some extra juju in that car. He’s testing his product so he uses these races to test the max trims and then scales it back a little to keep things safer for the avg consumer.

        would like to know more details on both cars.

        Who knows maybe the 440i was acting up? A b58 recently reported engine failure due to fuel injection issue that melted cylinder 1. BMW quoted 23k$ to replace entire engine....Click here to enlarge I’m sure he’s evaluating different options like used engines.

        There aren't many used B58's yet... that $#@!ing sucks.

        He should just light it on fire.

        BMW wasn't in turbo denial. They were building better motors and winning on the race track in actual motorsport. Where was Nissan? Oh yeah, cheating on the 'Ring.

        BMW didn't turbocharge an inline-6 due to any Japanese competition. Come on, only now is Nissan coming to market with something in BMW's class that is turbocharged and not the other way around.

        That's very confusing until I click on the link lol

        Wonder what JB4 on the Q50 Red Sport would do......450whp???, not too bad except for how the car feels/handles on a daily usage.

        Is the Q50 in the vid AWD? That prolly explains....

        Nice, name calling. Loozer trolls on every forum I guess.

        The Turbo version of the 2002 was a total failure, they made 1700 of them and axed the model.

        Ferrari is a poor example, their primary sellers, the 488/portofino are turbocharged. You should have used Lamborghini as an example, their entire lineup is NA.

        Maybe you haven’t noticed but cars are getting heavier, a NA engine just does not have the torque to be competitive. This is why small-medium sized turbos are being used by every manufacturer, to increase torque and driveability. Yes, the advantage is real-world fuel economy may be slightly better. Even more to the point, in the HP war that we are having now, TURBOS RULE! NA takes a back seat, nobody cares because they just do not make the power needed to meet expectations and be efficient.

        Japan was using 3.0L twin turbo motors since 1990, the 300zx-Supra-3000gt all had them and they all made over 300hp, it took bmw 15+ years to build a sort of proper n54 turbo motor and they made it sound like it was the newest discovery as they were using it in most of their lineup and guess how much more power they made than ancient japan -> 0 more power @300hp.

        Now All bmw gas/diesel motors are turbocharged, even the high performance M3/M5, you would need 8L NA to compete HP wise in the 600+ super sedan class-> or a 4.4 turbocharged V8, and 4.0L T V8s from competitors.
        Its just not about the epa, they need to compete performance wise and meet their margins.

        Porsche- who is talking about purists cars? The 911 Turbo has always been Porsche’s signature car, you know like in, “I have a Turbo”-> This goes all the way back to the 1970s. Nobody even knows or cares about the GT3 except purists.

        Ferrari isn't a bad example they literally still produce NA motor and they just now went to turbos on their V8's. The 458 which is the same basic platform as the 488 is naturally aspirated.

        This 440i is a gran coupe. Maybe he was also on a conservative map. Either way, impressive result for the Infiniti.
