• The N54 finally comes into its own - Vargas Turbo Tech Stage 3 N54 (335/135) twin turbocharger upgrade sets new N54 horsepower record with 693 wheel dyno

      Congratulations are in order to Vargas Turbo Tech as well as Cobb tuning and ProTuning Freaks for raising the bar as to what the BMW N54 inline-6 twin turbo motor is capable of. There are two platform records here the first of which it is important to note was achieved without methanol injection. There are certain tuners on the N54 platform that mask their ability to upgrade and control the stock fueling system and any fueling issues are "solved" by dumping in a ton of methanol.

      Well, with no meth and the cars own fuel system (with High Pressure Fuel Pump tweaks courtesy of Vargas Turbo Tech) responsible for all the fueling 673 wheel horsepower was achieved in STD correction on a Dynojet. That is a record for horsepower on the platform without methanol injection and was done with a blend of MS109 fuel and 93 octane.

      Meth injection was then added and the figures rose to 693 wheel horsepower. If more time was available for the parties involved including Josh at Cobb as well as Jake and Dzeeno at ProTuning Freaks the 700 wheel barrier likely would have been crossed. This will happen sooner rather than later now but this is still a major milestone and a new era the N54 is entering. The motor is finally starting to mature and although it is not on a comparable power level yet with the top BMW aftermarket options this is a huge step step forward for a platform that spent considerable time in limbo due to fueling and tuning issues.

      It must be satisfying for all involved especially Vargas Turbo who was doubted by many early on due to being a fresh entrant on the N54 tuning scene with many fanboys blindly following another tuner providing a turbo upgrade. Vargas Turbo Tech, Cobb, and PTF have surprisingly quickly surpassed the results from a competing turbo kit that uses a single turbo setup and have done so without relying on meth injection band-aids. A true fueling upgrade is here as well as a turbo upgrade making some serious power and setting the standard.

      Congratulations and much respect to all the parties involved, dyno graphs and videos are below.

        800whp in a race tune ... On a race track... With the right setup...
        I'm not talking about that. Power delivery of a car with great suspension and a big turbo really isn't all that great. I'll take a GT3 thanks.

        We're going to compare a gt3 to a supra....

        the supra would likely still lap faster too haha

        ... Not saying i wouldn't take the gt3 over one if i was offered it...

        If you want to talk about driving pleasure you better $#@!ing bring up the GT3 or stop talking to me.

        True... Pure.

        i will always agree that a high revving high powered N/A engine is as pure and perfect an experience as it gets, and the gt3 is at the top tier.

        Meh. It's really not THAT great now. It was for the time. But outside of the engine it has, it's not really all that special. It got by on handling numbers by grip alone. The steering was still the typical Toyota numb feel and it didn't do all that great in quick transitions and tight tracks. It can be upgraded to be awesome. But then you can do that to a lot of cars Click here to enlarge

        i dunno about over there... But japan/here(aus) supras definitely are still competetive in timeattack rwd and im pretty sure they still race in some jgtc stuff?

        i don't mean unmodified, thats no fun to compare haha... Stock, they were in fact a tad porky lol

        i never thought they steered numbly though, at least not the handful i drove

        Stock suspension? Absolutely not. The time attack supras have all the bushings replaced, helps a ton with the steering feel. Stock Toyota steering is almost always numb as hell. The FRS and IS-F is much better.

        I was talking about stock vs stock. The Supra handles better than the 335i stock for stock (but not much, and mostly due to LSD); but won't touch an M3 with a 10 ft pole.

        Yup. The interior was so advanced for the time; I LOVE the driver-centric cockpit. And it has this $#@!ing eyesore of a steering wheel. It's worse than the C6's running Malibu steering wheels since that wheel actually flows halfway decent with the rest of the car.

        You manage lag the same way you manage the low trq in a M3, put it in the right gear. Newer smaller turbos make the same or more power and have little lag.

        A stock supra has pretty respectful handling and very good brakes even by today’s standards. Improve the suspension, coil-overs, LSD, brakes and tires etc… and handling, braking and grip is amazing.

        Love my M3 especially with the SC has all the bells and whistles and while it may do some things better, at the end of the day if I had to pick one, it would no doubt be the Supra.

        Lag and throttle response down low aren't the same thing.

        I'm sorry to hear that but your opinion. If I had to pick it's the high revving NA motor especially a V8. But that's me.

        Ohohhhh we're talking stock... Yeah, fair enough. M3, even an e36, compared to a supra...
