    • 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.

        Any more information on this new manifold? Is there room for a tapered log style with internal VSs and short ass runners? You would need to modify the charge piping...

        the runners are longer. They have to be to get up and over the bolt on the oil filter housing.

        I assume you made all of the runners longer? Is the charge pipe in the same place? Any more info you want to give out Click here to enlarge

        I am going to post a whole thread tonight or tomorrow with pics and all that. But the stock charge pipe will fit, I might have to include a coupler or adapter to make it fit, but this is made to work with everything you already have...as long as you air filters are cone filters.

        I don't think I was talking to or referring to your post in my reply that you quoted. I was just making a general statement when it comes to meth traveling down charge piping and through the runners.

The flatline/major correction has absolutely nothing to do with manifold design and everything to do with perceived torque within the tcu. Please forward me these logs btw when you have a chance.

        And again its not unique to my car and everything to do with the fact you aren't tuning with all available tables within the DME.
        LOL Not sure which way to even begin to respond to this nonsense anymore haha You have the logs you're looking for from your own car. I don't see value in arguing the obvious so let's agree to disagree and move on?

        We are discussing an issue that your stage2/3 customers will inevitably run into on a 6AT. Considering you are tuning your stage 3 setup on a 6MT, you haven't seen the issues relating to it. I don't have an axe to grind with you, but perhaps you should take a step back and digest what is being stated instead of making personal attacks on someone discussing something you will run into.

        OK, so how about you tune all 6ATs on race code with throttle angle at 75-77 degrees (which you found by accident no less) instead of the normal 80-81 and call that your fix riding the load limit in the powerband? As you confirmed previously, these issues are not related to MY car specifically and you know this.

        But yes, let's agree to disagree and move on.

        Actually, we were discussing a major cylinder 1 correction on benzy89's log, and all of a sudden you're speaking of meth flow due to an intake mani design issue on cyl 1. So yeah, in context, it is all related.

        Thinking it might be an injector related issue, which wouldn't be a surprise since I have the original 6 still in the car (June '08 production). I'm going to log it a couple more times & see if the issue remains (confirms the injector problem) or if it goes away (then an isolated Cylinder 1 problem).

        I have hundreds of logs trying to diagnose this problem, trust me, it's not your injector. Still on my original set of 6 injectors too (01/09 prod).

        The only way I corrected the problem is to stack the JB4 ISO.

        This points the problem to "bad tuning", I think. If you have major timing corrections after shifting, you must make sure that the timing is right for that load (loads after 6MT shifting are quite low, like 80-90 when shifting close to redline) and also you must make sure that the boost spike after shift is as small as possible (I corrected this by altering the D-Factor Multiplier table in ATR - but only after the WGDC Base table is spot-on). Once I did this, I had no bog, no flatlines whatsoever.

        So what's the issue then? You're all set, on 1 cylinder Click here to enlarge

        Anyone remember when we made 572 and 537 on 91 only no meth first time on the dyno...Click here to enlarge Seriously getting excited for this kit to finally come to fruition and now it is so much more polished, been a long frustrating road! Seeing the light at the end of the tunnel! Click here to enlarge
