    • 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.

        E-tuning is simply a method by which logs are taken during a run (WOT, part throttle, what have you), then sent to the tuner. The tuner makes changes to the maps which he sends to the driver to upload the the car. Rinse, repeat.

        Eventually, a proper tune to your specific car can be dialed in and the tuner doesn't have to be on the same continent. Maybe a more proper term is tele-tuning, because electronics are involved in the tuning process regardless. Isn't the internet wonderful?

It's not like anything drastic has been changed: the Vargas Stage 3s are still a twin turbo setup that operate in the OEM vacuum controlled WG fashion. You'll need to monitor all your normal channels when tuning, you just slow increase your values.

        I understand that it'd be a lot easier to have a starting point closer to a finished product (vs. using the OEM Turbo OTS Maps and slowly building them to support twin GTXs), but it's still going to tuning the exact same way.


        Side Note: Tuning yourself with stock turbos, you're more than likely to destroy the snails before you seriously inflict damage on the motor. With the Stage 3s, you're more than likely going to ruin the motor before the turbos. Because I have no credible tuning knowledge, I wouldn't "tinker and play" with this kind of setup in ATR unless I had a concrete understanding of what I was doing.
        Carl isn't your typical tinkerer.

        Yea, eTuning is real simple. The best thing to do would be to get some "rough draft" tunes by doing some full gear pulls & trading data logs for revised tunes with your tuner. When you get to the final product, you might want to rent a dyno for an hour & agree on a time with the tuner to make sure you get the best quality, finalized tune. Could easily have a dyno operator take the pulls & data logs and then do screen share over the internet with the tuner and nail it down.

        Great numbers, guys! Awesome to see such a powerful update. Kinda sucked to have to read through so much childish BS to get any decent information from the rest of the 12 pages.

        If he works there shouldn't he know his cars and turbo setups better? As well as his BS? Or does it just rub off on you when you get in bed with Shiv?

        They don't HAVE to be paired with Vishnu. Sounds like some other tuners might be able to extract a bit more...

        Or maybe they have something in writing which is why his balls are firmly pressed against Shiv's chin.

        It seems like the same old same old with any of those guys. Mr. BS Info with mud bucket in hand is on their payroll but forgets to mention that bit of info.

        Modern day 2jz, ďmaybeĒ. The N54 is turning out to be a great motor capable of easily making and handling a lot of power like the 2jz.

        My Supra was BPU for a while, 420Whp I think I spent around 3K on quality parts, close to what I spent on my FBO 335 but made less power, donít like meth. For more than 10 years Iíve been running over 560Whp pump and over 800Whp race, stock block, Iíve changed one water pump and do regular maintenance, thatís it. The 335 was fun but reliably was becoming a concern with more visits to the dealer than I care to mention, sold it and got the M3.

        Stock M3 made all the right sounds, handled well but those pesky 335s were a challenge so I supercharged it temporally solving the problem. Now they have turbo upgrades and can make serious power but can they hold over 600whp for years on end, only time will tell but its good to see the I6 back in the game.

        The new M3 will be interesting as a factory built, built I6 with great potential.

        What gets me most excited when I go into the garage, the Supra, love my DCTM3 but the fun factor goes to the Supra.

        673 Whp is very impressive and deep into Supra single turbo territory.

        Great work.

        How does fun factor go to the Supra for anything other than a WOT blast you have to wait to get power on? Fun doesn't equal whp. And turbo power delivery to get big power on the Supra has lag.

        ... The 2jz may be well known for making risiculous numbers.. But you ARE aware that a well setup supra handles EXCEEDINGLY well.

        800whp in a race tune ... On a race track... With the right setup...
