    • 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.

        They already said there wouldn't be excessive testing until the new LSD, DEFIV Lockdown & some other goodies got installed, so it might be a couple weeks before we see 1/4 mile & 60-130 times.

        Pretty sure he said they'd be doing E85 testing this weekend; that and resolving the spool issue (and it looks like he found it).

        That's good to hear! Outside of higher limits (Boost, etc.) what other features or avenues does the race provide?

        Let's be real: if you can afford a ~$5k+ turbo system, you can afford the $500 it costs to PROtune
        Not everyone wants someone else's locked maps.

        It isn't a question of money.

        Not really I'm capable of differentiating between power builds and driving respone/pleasure. Like a 911 Turbo versus a GT3 but apparently that's hard for you comprehend.

        The small v8 in the m3 is good for neither response or power when you compare it to a similar built lsx. But we all have our reasons. It beats the n54 however in both, why do we care?

        I have to disagree on the response part - power, yes for sure. I haven't seen many motors even close to an S54 or S65 as far as throttle response goes - and I have seen many. Tuned or not.

        By response I meant low end torque, power responsiveness, not how quickly it revs. From a throttle response point of view the M's are great. Porsche comes close. Sport bikes destroy them all. Still not sure how this is pertinent to anything really, I digress.

        Not good for response or power? Uh better response than a high revving V8 with independent throttle bodies and mafless design with over 100 hp per liter... right. Click here to enlarge

        This is kinda old news now as this was fancy in 2007, but I'll just leave this here. http://forum.lsxtv.com/showthread.php?t=241

        925hp at 9600 rpm on a 6L LSX. That works out to a bit over 100hp/liter, and it's N/A. It's in the 8's, where is your car at?

        Nope. I have absolutely no clue what I'm talking about. Stroke is the most important thing to high revving engines. But go ahead and continue talking about hp/liter like good ricers like it has anything to do with anything is racing. It's all about engine design and goals. Sticky has certain goals with his project, and wants to use a M3 base. That's cool, but an M3 the most responsive engine ever when comparing to other projects? Laughable.

        925hp on a N/A LSX? Nice! I don't even want to think about how crazy the cam they're running must be. Does it idle at 2000rpms? Click here to enlarge

        I'm confused as to what you mean when you say 'Stroke is the most important thing to high revving engines'. I've seen a lot of conflicting information over the years regarding stroke's importance. Many of the articles in the tech section on this site pretty much make it sound pointless; which I know not to be the case. My understanding is that increasing the stroke increases the amount of air drawn in on the intake stroke, but can be detrimental at higher rpms due to piston speeds. Is this correct? Trying to learn here, and like I said, I've seen a lot of conflicting info over the years; much of it I've seen proven wrong with a cursory glance at physics.

        One again wheel horsepower has nothing to do with it you're just talking about modifying for power, oh wow. I'm sure all the GT3 and Ferrari owners are lining up for LSX swaps. Living your life a 1/4 mile at a time much?

        No, you don't know what you are talking about. HP per liter on a 4.0 liter V8 shows high volumetric efficiency. Notice the M3 V8 racing in ALMS isn't running 8's? Notice it just smacked the Corvettes around? Of course you do, because yo know what you are talking about right? Hence why you mention wheel hp as if it has anything to do with the points made.

        Yes it increases piston speed guy doesn't know what he is talking about once again.

        When going to very high revs, stroke is very important - to be short.

        Agreed. The article pretty much also says that the oversquare motor will outperform the square/undersquare in every scenario given the head/cam and gears are profiled to match accordingly. That is the part I'm not so sure about. It pretty much states that stroke does nothing except get in the way. Maybe I misread it, but I'm pretty well-up on my statics/dynamics Click here to enlarge

        Not a simple comparison in ALMS, they "equalize" the cars and deliberately slow down fast cars via ballast and restrictors. There's not really any question that in a no-limits format the LSx engines are just flat out superior to the S65.
