    • 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.

        NOT the best log (you'll see TPS gets wavy & I had traction control fully on) that illustrates the 3-4 shift on my E85 map is fine.

        Timing returns to +9* in under 0.5 seconds (which includes the shift, where timing goes negative to not damage the 6AT)

        Too lazy to plot it on a chart but looks like timing dropped down to 3 degrees post shift before coming back up? Which, is basically what the post shift timing drop issue is. Only over a second or two rather than just a couple data points. What makes it so frustrating is that it will come and go. Changing on a whim. Unless you happen to monitor advance all the time in dash or log often you might never notice it. And there are cars that for some reason never experience it. So if you are not effected consider yourself lucky. The only explanation I've ever come up with is some hidden load based timing table triggering some sort of a torque limit. Rescaling everything to run a lower load on our flash basically solved it.

Wow finally what I believed in this platform is coming true. Easy azz 10 sec car with these turbos especially paired with a DCT N54 and RENNtech's camshafts.
        From what I recall, you haven't encountered clutch slip, but if you plan to go this route and lay down heavy torque, what do you plan to upgrade the DCT with?

        I may give SSP a try on their softer clutch pack and have the bar pressure raised. Before this though I will have to find the wtq limit onthem.

        Last I checked, you can monitor those things in INPA but you can't output the data to a log. Live video of INPA in action?

        PS Dzenno the above statement should clue you in as to why you haven't seen a log yet.

        Err... you did flatline. Look at the -10.12 correction in 1st. Also you're running low timing across the board for an E85 map.

        The 3 degree event is traction related.

        Oops no its not, thats a drop related to boost mean abs overshooting. Should be quick to fix.

        I was thinking BT tool as it can log...benzy's got a timing correction one one cylinder (pretty bad) not a "flatline" in applied timing..different as you know..unless you're talking another log

        @benzy89 , on complete separate note why isn't your tune more aggressive it seems there is a lot more headroom with E85

        Actually any post shift timing issues relating to 6AT can be considered flatline, but thanks for being so technical.

        $#@!ing stock turbos man. The boost is already maxed on the 93 octane map, so it's not like we can add more on the E85 tune. SO all you can do is add some (safe) additional safe timing. It def wasn't a quality log & I'd be willing to take more, but my AP $#@! the bed over the weekend so I had to ship in to COBB for a screen replacement Click here to enlarge

        Sure especially when you're logging off cylinder 1 and cylinder 1's timing is timing-corrected. There's simply no way to know any better. Otherwise I'd simply disagree.

        $#@! dude!

        I was running close to your boost level, but had more timing in it. granted I was running meth, but even without meth and on E50 Dzenno was able to squeeze may be 3-4 more degrees of timing with no timing drops whatsoever. Just a thought Click here to enlarge

        @benzy89, is that log from your Brenn E85 map making 460whp on his dyno?

        There is definitely a HUGE correction in cylinder 1 on those logs @benzy89 just like @dzen no and @themyst said...

        I attached a picture....Never seen such a large correction myself in any of my own testing...Would have me worried for sure but really surprising how its such a large correction on only one cylinder...

        Attachment 28522


        Also @themyst if im not mistaken dzenno is correct that this is not a "flat line"....from what i have read won't the flatline show under actual timing but wont be shown under corrections? (will be subtracted)...I know both of you have way more experience just curious...am I wrong?

        FWIW Many a time you'll simply have cylinder 1 quiet and never/rarely complain (timing correct). Tuning high powered N54 (large turbo or turbos) with the way JB/Procede log timing today (just cylinder 1 and flying blind on timing in the other 6 cylinders) is just really risky business IMHO. Doesn't give you an opportunity to realize any issues early on and address them on time.

        It may just be heavy carbon buildup in that cylinder slightly changing compression characteristics there (but not other cylinders) and may just need a good valve cleaning or maybe some seafoam might help clean the piston tops or maybe even a bad spraying injector might be needing replacement.

        As much as I have used the JB4 with success in the past and still think its a simple, easy, efficient, and amazing tool for the right person....I have to agree with you that this is a GOOD example why just having access to cylinder 1 could be a nightmare..

        They should just add the darn logging Click here to enlarge Shiv even showcased it before so it seems doable and yet still doesn't have it added to the procede.
