• Vargas Stage III Turbo upgrade for 335/135 N54 motor hits 572 wheel horsepower on 91 octane pump gas (no meth injection) with Cobb flash

      Well here are some results for the Vargas Stage III upgrade that has caused the N54 forum section to basically be engaged in chaos for the past few months. From accusations of vaporware, to comparison to single turbo upgrades, to countless other arguments the day has come and the Stage III Vargas Turbo upgrade dyno'd on 91 octane with no meth 572 horsepower to the rear wheels. This is with a Cobb flash tuned by BimmerBoost vendor Pro-Tuning Freaks.


      Impressive? Yep, sure is and this seems to also be a 91 octane pump gas only world record for the N54. Now keep in mind this is just the beginning. What will it do with meth? What will do on E85? What will it do with race gas and big boost? What about different turbos? Sky appears to be the limit but for now this kind of performance on pump gas sure is a big boost (hah, get it?) to the N54 scene.

      Congratulations to all involved, Vargas Turbo Tech, Pro-Tuning Freaks, Cobb, and just the N54 community as well. The impossible just became possible. Pictures, video, and dynograph below.

        Yeah not sure if its due to my 7" ETS intercooler causing more lag or if I have a sticking wastegate actuater. Either way full boost around 4k is fine by me.

        DZ, you know you're going to get the 67R, who are you kidding. Get to work, you have some records to break Click here to enlarge

        totally agree with this!

        Pulled the trigger and switched from stage 2's to stage 3's!!! Going for the gt28rs setup ,unless I change my mind. I'm pretty sure my 6at wouldn't want anymore power than those on pump. But they still leave me with headroom after a legit tranny upgrade comes along.

        Even before you get to full boost, you're already flowing more than the stockers could anyway Click here to enlarge

        What's the estimated install time difference between this and replacement turbos? How much permenant modification to the car does it require?

        Did you use an EGT Sensor?
        What temps did it run?

        I don't think there are gonna be any more tune revisions/updates until Dzenno & Jake fly out (IIRC they're both going) to tune the car in person. Only so much you can do with eTuning

        Good decision.

        No, we don't have one hooked up "yet". I'd love to monitor EGTs as well but so far we've only gone with what we can get through the AP. On the next round of tuning we may have some additional/external sensors put in, we'll see.

        At the moment it looks like its just Jake going. I've got some contract things to sort out in my regular day job/career end of this month beginning of next.

        In terms of eTuning, it isn't limiting us in any way whatsoever. We are going to basically meet Tony and possibly some people from Cobb. We had an agreement with Tony while the kit was being produced that we'd come down and we're simply holding to our promise. Another 2-3 hours on the dyno and we'd most likely have an ACN91 tune at a state where we'd say its done for what the current HPFP can provide.

        eTuning was the wrong word, street tuning is what I meant (since you'll never be able to recreate the conditions experienced on a dyno on the street). Obviously the whole tuning process goes a lot faster if the tuner is there in person & the cars on a dyno, but it's awesome that the current tune is nearly done & just needs a final "polishing"

        Should bolt on similarly unless there are some custom bits outside of standard install. You can add an hour to the expected time for stock turbos simply due to familiarity issues.

        Street tuning on this setup got us very far tbh Given this is such a different setup hardware wise (yet so similar control systems wise) dyno tuning is also a must to create a solid "base" tune. Once you've got a good base (sort of like an OTS map) street tuning works really well again.

        In terms of the overall tuning process/delays given that changes need to be reflashed to the car (about a min and car needs to be restarted) the reduction in time (speed up in tuning) would basically involve Tony not having to download a new map from the dropbox and us just flashing it directly on the car from ATP Click here to enlarge honestly, that is simply it

        However, if there are some odd "drivability" issues that simply can't be visualized through logs (e.g. maybe a 6AT transmission complaining like it was pre-Alpina TCU flashes) then being there in person may/may not help solve them. At the moment we are happy to not have such problems and according to Tony the car drives smooth both part throttle and WOT. We'll see how/if any of that changes once a 6AT car is ready to be tuned. More electronics, more fuss Click here to enlarge

        Hey Dzenno, sorry if this has been asked but I don't recall seeing any detail on it. What did you end up using for boost control? I saw boost was set to 24-25psi. Wasn't there talk of a ceiling in the rom? Or was that overcome by cobb?

        Boost control is done entirely through the DME at the moment. There is still a ceiling at 22.5psi but we're getting around it with some "cheating". Cobb is working raising the actual boost limit and hopefully we'll have the ability to use that soon as well.

        Dzenno just a heads up but you all(or Jake at least) will be tuning my 6AT when I get my stage 3's. I am the winner of the free etune you guys gave away on Facebook a few months ago but Jake said it was fine to hold off till my stage 2's but now I'm going stage 3's lol.i I understand these stage 3's will require more work so I will gladly pay a difference if tuning these is more than the value of the tune I had won. Thanks in advance to you and Jake
