• Vishnu Tuning E92 335i with FFTEC N54 single turbo hardware + raised boost finally runs a 10 second 1/4 mile pass, underwhelming?

      Vishnu Tuning finally managed to eek out a 10 second pass in their single turbo E92 335i that they were once touting would be in the 9's. After multiple unsuccessful attempts (with driver errors) from Vishnu owner Shiv Pathak he was able to get a high 10 second slip by raising the boost according to his data log and shifting cleanly. Details are scarce as Vishnu did not provide information on the youtube video upload and there also is no exterior view to show the slip actually correlates to the run shown in the video.

      We will give the benefit of the doubt here but with all secrecy and the multiple attempts to get to this point the performance is simply underwhelming for the time and money investment. The car is said to have run 10.8@131. It recently was dyno'd at 627 wheel horsepower by Insideline so these horses are not translating well to the ground. This single turbo offers considerable lag and the top end pull for the sacrifice simply is not there especially compared to existing solutions such as the Rob Beck twin turbo upgrade which offers far greater spool and performance only a few miles per off through the traps but with far greater driveability.

      The previous record was 11.10@127.21 with 19 psi of boost on the RB turbos. These turbos are a much more affordable option that also currently is available. Vishnu claims 23.5 psi of boost for this 10.8@131 mph run. Is it worth the minor top end benefit for the estimated $8500+ plus install? We do not think so and considering the way Vishnu hyped this the results are very underwhelming. The low end torque sacrifice is not being justified with a large top end gain.

      We wish Vishnu luck in the future but for now this is still an experiment and work in progress that is tough to buy both figuratively and literally. There are more affordable options that work better for daily driven N54 vehicles that offer 97% of the performance in practice (as in not just a dyno queen) with less compromises. Not to mention for users to repeat what Vishnu has done here with their own single turbo it will likely be far more difficult as they will not have the option of risking their engine with higher boost and timing advances simply to try to eek out a tenth to squeeze past what already exists and get into the 10's. It may be a record, but it certainly is not impressive considering where the bar was already set with far less horsepower and much more affordable tuning and hardware options.

I'll be going to Laguna Seca in early Nov, but that won't yield any definitive power related numbers.
        Just out of curiosity, not trying to be an $#@! at all, why wouldn't you desire to hit the strip for some real world application of your $10,000 investment? God knows if I got a single, I'd be at the strip the next day! I wouldn't necessarily launch the car hard, but I would definitely like to see where the trap times are at. Just wondering, no ill intentions, I promise!

        Like I said I'm sure there is a good reason behind it, they probably have some real life stuff they have to take care off. It's just very unusual specially for car enthusiast. Usually when a breakthrough like this happens everybody is going to the tracks, taking video of a highway pull or a little spirited run in the mountains and after that people will usually put up reviews and some peoples cars will break because of the added power and torque. But there's almost absolutely nothing not even a "hey my clutch is slipping" posted. It's just very unusual that's all.

        Some are not into drag racing and tracks can be far away. If you want to test your car, a 5hz or 10hz gps works well. They are very cheap and very accurate. Find a level road with no traffic at night. Instead of spending hours in traveling and then waiting, you are done in minutes depending on how close you are to a suitable road.

        Haha you are the first guy here who hasn't tried to stab me through the internet.

        There are only two strips I know of around here: Infineon and Sacramento Raceway. Sacramento will kick you off if you break 135mph without a cage. I was on the Infineon drag strip in my friends vette a couple of years ago, and all I remember was waiting in the heat for a few 11 second runs of glory. It was fun, but I much prefer track days. Driving in a straight line just doesn't do it for me.

        As for the real world application of my investment, I can feel it under my right foot. I don't need to see the slip to validate what I already know. That the car is incredibly, scary fast. Looking at the speedometer I think I'm even faster through the high speed hills around here in my car than when I'm driving my buddys GTR. Although I don't feel like I'm going to die in the GTR like I do in the 335i.

        I may go to the drag strip sometime if and when I feel like it, but I'd rather spend the little free time I have enjoying real world driving.

        I know you guys want numbers, and that it's hard waiting around for someone to care enough about forum members to sit on a drag strip and provide them. But I'm a selfish prick, so you'll have to wait a little longer Click here to enlarge

        Thanks for the honest and respectful post.

        Yes, it's much more likely that I'd get a vbox. What would you guys want to know from that though? 60-130? I don't think they work well for the 1/4 mile? Also, I don't think there's a long enough stretch of road around here where I'd feel comfortable doing that.

        They do the 1/4 mile it just isn't a substitute for a timeslip. Still, it will give us info.

        I have Qstarz BT-818xt and use Dynomaster on my Galaxy S3. It is a superior solution especially if you have a phone anyways with more processing power than external devices that can do one trick only. I record 3rd gear from 2000RPM to the redline if I want to know a true effect of an additional mod or tune adjustment, without having gear changes to deteriorate the data. This way I can see the real world full rev range performance whereas 60-130 gives the top end only. Also, it is important to log the times of gear changes as well just for being able to make them as quick as possible. Of course, 60-130 would be the one to do and post in case you have the need to boost your ego on a forum. However, since this is not a civic forum, most of us might not have that need.

        The 1/4 mile on a dead flat road provides for scarily accurate VBOX quarter miles. 12.4@118.9 on VBOX, 12.4@117.91 on the timeslip from Atco. I think it could be a viable database if the slope is kept under 0.1 +/-.

        Im sorry, i dont buy it, everyone keeps saying "im just enjoying my car" but are they, really? look at what they did prior to the install, "hey guys, i ran a xx@xx today", "ran a turbo xx on the xx expressway" now, they are "just enoyoying my car" no video's, no feedback, NOTHING.

        FBIS is definitly waiting for a fix on something. a few days is what he needed to write pages on dumb $#@!, like the riss racing catch can (which you guys now know doesnt wor properly, and he never said anything but great things about), or the stett charge pipe, or the CF hood ( that doesnt fit but he tried to shoot at angles that dont show it)

        FBIS is a reviewer for hire for sure. He got extremely pissed when I mentioned that.

        he's had over a month and counting, and the best he can do is a fire extinguisher bracket, and now a 2 gear log that looks suspiciously like it was done on a dyno

        FBIS has always posted "im just enjoying my car" so don't even dream about any quarter mile times. It is not his style. So, nothing new here.

        I remember his Riss Racing OCC review. A can that costs $2 to manufacture in China and is worth nothing. He does the review, but does not really mention the negatives.

        However, what can go wrong in a simple turbo upgrade as far as you have half a brain to remember the DME thinks it runs twins and place the O2 sensors accordingly? I don't think the speculation of the turbo upgrade having a technical trouble is warranted. It spools slower than RBs, but its a feature, not a bug. The transitional spool is not too bad actually.

        oh, i certainly agree that i didnt actually expect 1/4 time or 60-130's, he never di any of that even when it had n20. I wouldnt have brought it up if he hadnt been the one to mention he would do it, and then backtrack. But the other guys, the "10+" Oof them, certainly have no reservations about touting achievements, if they make them...

        The more reviews i re-read of his, he never mentioned flaws.

        Im not saying its flawed technically, but mechanically, something is right. Im only partially psychic, so i cant see if its in the tuning, in the fftec hardware, or the motor itself, but it has an issue and he is waiting to post. Whic there is nothing wrong with, as its leverage to get the shiv to actually fix an issue, as opposed to blaming everyone and everything else, as is his M.O.

        I spoke to a FFTEC/Vishnu kit owner a week or two ago who is having problems with boost spikes, drivability, etc. So perhaps all the bugs are just not worked out yet.

        I have a feeling real tuners will have their hands on the hardware soon enough and make some much needed improvements and feedback Click here to enlarge

        If any of these smartphones would have a 10hz GPS chip instead of the current 1hz chip, the phones would be as good if not better than the vbox.

        It may be accurate but it still is no replacement for a drag strip. It will tell us more info though.
