    • 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.

        This is so true. My previous E46 M3 had subframe carnage almost as bad as that thread on this forum. The E92 feels MUCH more rigid even with 70k on the chassis, but there is still some flex in the subframe noticeable while maneuvering around driveways and uneven pavement. The E90 feels even more rigid and tight and the flex is nearly absent.

        Disclaimer: I love JB4, was a very happy customer. Not a Shiv lover at all, if i had to side I'd be in Terry's camp. Also, about to be a proud e92 M3 owner. But when I read Sticky's "article" (or whatever you want to call it) on this achievement, I feel I should post.

        You use the word "eek" as if it was a complete fluke, and he barely managed to get into the 10's. "eek" is more appropriate when the time is 10.99, but I'll let this one slide.

        Whats with the negativity, you think it takes no skill to hit 10's in a 6MT N54?

        You expect him to have a 4 page article going along with his youtube description? I am not surprised he did not share detailed info on this run with you, you are trying to discredit him every chance you get.

        this isnt a Speed Channel documentary on the 10 second run, how many angles of footage are you expecting to back up a guys 1/4 mile pass and scanned time slip before you believe it?

        and how many attempts did you make at getting into the 10's or better? Enough to break your transmission. How many times did you make 10 second passes?

        Lots goes into R&D. If this is a customer car however, the customer would have been able to get into the 10's for much cheaper than an e9X M3 owner with supercharger/Nos/etc. So this statement is simply incorrect, and I read it as "I'm jealous".

        Quicker spool yes, but clearly less performance. So, again, your statement is incorrect.

        How do you know pricing, pricing isnt even available yet? Also, with RB, you had dozens of people attempting to get glory 1/4 mile passes (some of which are great drivers), versus one guy who might not be that great of a driver.

        Estimated? How do you estimate that, and what other components does Sticky "estimate" that this kit comes with? I estimate you are envious. Put that on your front page seeing as we are throwing subjective info around as if its an editorial.

        Compared to what, a neon SRT4 with a tune? Sure I'll agree with you there. I'd say a 10 second newish BMW for less than the price of a E9x M3 is far from underwhelming.

        I beg to differ. People will push the envelope even more than this one guy did. Just wait til there is 50+ single turbo conversions. These records will be shattered. Mark my words!



        I understand that this post might make the owner of this site angry. I just can't sit by silently watching anymore. Sticky if you start posting more objective information vs. statements that stink of your personal opinion, I would be a happier contributor to this site.

        No, I used the word eek as in they barely did it. Never said it was a fluke or that it would not be possible. Maybe you need to look up the definitions of these different words?

        I kept saying it was coming. It's a high 10 that took higher boost and multiple tries. They eeked it out. If they didn't, it would not have taken so many attempts and would not barely be in the 10's.

        Based on information like this, perhaps you should try reading?

        Not the brightest bulb now are you? So that is likely going to be 8500 PLUS install.

        I'm no experienced drag racer but I don't think 10.82 is "barely" in the 10s. Also, it was the first and last pass of the day before packing up and driving down to LA that same night. No multiple runs were involved. And contrary to what Sticky suggests, it didn't require extra boost. Nor a more aggressive tune. The only difference between that and the low 11s passes from the previous week was that I adjusted the 2-step logic to allow for a more aggressive bog-free launch. This stuff takes time to work out as we are doing things that others haven't done. How Sticky manages to use that against us is beyond me. But this is his play ground so he can take back all the toys if he wants do.

        Also, if he were to read the Edmunds thread that was started on e90post, he would have seen a response by me stating that the price listed in the article isn't accurate. But he doesn't read e90post. So we can't expect him to read info that the rest of us read.

        Well, that's my post of the day. Have a great night gentlemen.

        Inaccurate as too low or too high? That's the first ballpark figure we really have. So unless someone has some other numbers to go on...

        You barely got in the 10's after a bunch of low 11's, come on now.

        What do you mean multiple runs were not involved? You have been trying for a while now. You seem to be confusing that particular day with all your attempts as a whole.

        I don't read e90post, please stop mentioning e90post. I DO NOT CARE ABOUT E90POST. I do read Insideline, so take it up with them. You are the one who worked with them on the article. Quote a price then if you have one.

        Doesn't matter, anything you or anyone else says is just speculation. It would be best to just wait for Shiv to give an official price. It could be $200 or $200,000 at this point.

        Why would Vishnu provide that figure to Insideline then? What, you think they just randomly guessed? If it isn't accurate, why have they left it there?

        Perhaps they are trying to mitigate pricing backlash or seeing how much they will be able to get away with. Obviously at $8500 my points stand.

        Maybe so, maybe not. I will not disagree or agree, because I do not know.

        10.80s is a solid 10 fair and square -- but you didn't really get it the way most were expecting. We expected with 725hp you'd power your way in with a high 10 coupled with big MPH off maybe a 1.7 60'. That's been the marketing pitch. More power than a driver knows what to do with. Instead it went the other way with a 1.5x 60' drag racer special launch coupled with relatively low MPH given the boost, weight reduction, and overall effort. Granted it's a manual so I guess you take the cards you're dealt.

        What happened to that auto single turbo?

        I do have to say props to both terry and shiv, it's very rare, if at all, to see a company that made the tune actually take cars to the track, most just tune, dyno, make adjustments based on dyno results, market, and then let the end users (consumers) make claims and adjustments at a 1/4 mile track.

        Dubstep, don't be too logical. The N54 can't really be that good any way, the S motors "crap all over it". (Sticky)

        The only thing I have to say, and I am really only familiar with Mustang Dynes, is that the trap speed is a bit low for 644whp. But again, it isn't DCT or Auto, and it was on a Dynojet, and is still a fresh setup.
