    • 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.

        Some people may say those numbers show lag, on the other hand I see it saving a transmission. Also I doubt seriously anyone would be able to hold down their rears if full boost was at 4k RPMs

        We will be taking this up soon, just looking forward to some track results
        Agreed. Smooth powerbands save drivetrains.

        900 wheel.... Yum. I think some of us might need to put the speed limiter back on the car for street driving!

        Wow!!! I got rid of my N54 at the wrong time.

        Nearly 700whp in a stock-looking 335i would have been epic.

        Congrats.

        @dzenno@ProTUNINGFreaks were any of the vanos settings tweaked since the exhaust isn't as restrictive, or is that another area that might hold some more power.

        I said this in my previous posts, and it's great & all that the Vargas Stage 3s are putting out all this power, but having a dyno sheet doesn't always translate to a win when the car's on the road (just look Shiv and the ST). Once the Stage 3s start getting into more consumers hands & people running them at the track or against similar powered competition, there's no guaranteeing that a N54 with GTX Turbos is the way to go.

        For similar money (car + mods), you could also go with:
        • Terminator Mustang & Whipple Blower / Twin Turbo setup
        • New Mustang GT w/ Coyote Motor + Whipple
        • Turbo E46 M3
        • Audi (B5) S4
        • Mercedes E55 AMG (W211)
        • EVO VIII-IX


        And the difference between all those cars and the Vargas & Single Turbo setups are those cars have proven themselves & shown that their dyno sheets = real world results. I'm not talking this down & I really hope that the VTT S3s translate to real world, usable power, but the "N54 is going to go down as one of BMW's best motors" is definitely a misconception.
        Agree and disagree, the car is an absolute beast on the road and I have driven a lot of cars. We can even launch it because we have no LSD, and are on stock axles. I also think they one of BMW best motors is simply how much power this engine can take in stock form. 700 WHP is nearing 850 crank on EVERYTHING STOCK. I think this engine deserves a lot of credit.

        any drivetrain upgrades scheduled/ what about performance data-60-130 & 1/4 mile plans?

        Once we get a LSD, Diff lockdown kit and upgraded axles we will be doing all of the above.

        The N54 is a phenomenal motor, and it def helps that it came turbo'd from the factory (making upgrading a lot easier, as long as we stick with the OEM setup). But Maximum PSI just hit the same numbers (700 WHP on stock internals w/ Race Gas) on their M3, and with the S54 you can hold a gear an additional 1.5k RPMs which is only gonna reduce acceleration numbers. And the nice thing about the E46 M3 is that it comes better prepared for a high HP setup (better OEM suspension + LSD). What the 135/335s easily have over the E46 M3 is availability (a lot more reasonably priced, N54s floating around then S54s) and easier to tune (until Maximum PSI, you had to run a separate EMS to effectively turbo the engine).

        How long have they been putting turbos on E46 M3's? This car has been on the dyno twice, last time with a $#@!ty last minute blend I am now being told is 96.5 octane. Yet we made basically 700 HP. I am pretty confident with some real 109 or E85 we will be over 750. This is hypothetical of course. But comparing a platform that has had its limits pushed for YEARS now to a kit that has been on the dyno twice and almost matched that number seems rather illogical. We will see where we end up when tuning is COMPLETE for all fuels

        Saw in another thread Dzenno mentioned you had turn off missfire detection, will you try to upgrade the flywheel on the car?

        I'd argue against the M3 being better prepared for high hp. It gets to a point where 'better prepared' gets really murky. Because at these power levels, the 335i's softer stock suspension is arguably better (minus of course the LSD missing and soft rear bushings Click here to enlarge )

        Whether the S54 can hold a gear longer is irrelevant. If the same average power is made across the rpm-sweep between gears at WOT, then one making the power at higher rpms won't make any difference.

        The Maximum PSI car DOES make great power. But you can't point at it and say it's normal, yet. We'll see how long it lasts and I highly doubt they've got the same amount of abuse put into it (maybe they do, but 145+ pulls is A LOT of pulls on the stg 3 car). And apples to apples, the N54 is still in its infancy. They JUST NOW got a S54 motor to do that. This is the second dyno publication of the Vargas setup. And you can bet your bottom dollar, there's a lot of other vendors looking into this right now. Vargas is making some serious waves.

        It'd be incredibly foolish & ignorant for me to not acknowledge both Vargas' & COBB's accomplishments with these Stage 3 turbos and setting the N54 record on a tune that still isn't a final product --like Dzenno (?) said, there are still some things that can be done to increase the spool, some additional power & still higher octane to capitalize on.

        As the N54 continues to develop (increased fueling, additional tunes like the ProEFI, built internal combinations, etc.), it'll be interesting to see when we hit the limitations of the motor. It's honestly a real shame that the N54 doesn't get the attention & credit that the GTR gets for putting out these numbers on a stock motor, but hopefully once you guys start churning out performance numbers it'll shake things up.

        I know of more than one 335xi owner with the funds to make a built drivetrain happen asking me questions about this stg 3 kit. I'm very hopeful Click here to enlarge
        I'm also hoping the sleeper look goes over well with a set of these Click here to enlarge

        When you will see low 10s all day long at the track, then the N54 will get the attention Click here to enlarge

        For those looking for a comparison, look at either the new maximumpsi turbo e46 m or a ICS stage one s5x.

        Seems like the spool comes on very late. Any way to get it to spool faster? S52 guys seem to get single Gt4094's to spool faster.
        Those engines are higher compression, the S54 definitely is, and offer more volumetric efficiency. The N54 can't match them.

        Beat me to it and I am an "S" motor junky. I thought we were in the N54 section? + rep for you.
