• 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.

        cost of used GTR... 55k, cobb ap $999, mid pipes $1500... trust me, that is by far the best deal. You will run 10.8@129 consistently, with massive ease and ran laps around anyone else on a track. Car will make 550 whp on pump but the type of performance you get with those numbers is nothing short of amazing... you can thank brilliant engineering for that. So if we are talking about a foreign car performance deal...that one wins.

        this is job well done for Shiv, there is more in it for sure. Sticky you certainly do like to poop on anything Vishnu related, u just live for it.

        Can anyone direct me to where the price is confirmed for this kit?

        vs a Supercharger if the exhaust manifold= intake manifold and the supercharger=turbo and the downpipe=charger bracket and if my granny had balls she would be my grandfather. Don't know why people keep comparing things. This kit is for people that actually own N54's and I guess its a matter of what someone is prepared to pay for it.
        I already got the RB's which cost me close on to US$6000 after shipping, customs and installation. Was it worth it, probably not from the outside but to me it was. If I had to spend a extra US$2000 to have a extra 100whp I would. Its only $20 per horsepower extra. Some people pay up to $80 per horsepower on NA cars when it comes to tune only.

        Because I don't live in Anaheim Hills?

        If Shiv or anyone else wants to meet I live in LA, close enough to where BimmerFest is taking place. If Shiv so desperately wants to meet me he can go right ahead. I'll pick the spot and Vishnu is paying.

        I don't think anyone will hook better but the question mark will be if the auto will trap higher due to the longer gearing and not losing boost between shifts.

        No, not at all. I really don't care one way or another. I had a very positive article going but Vishnu's attitude had me evaluate these runs far more critically and realistically. Facts are facts, this is incremental and does come with a sacrifice. I also hope to see it improve.

        There is not a confirmed price but the information given out to sources is $8500 ballpark right now.

        With more headroom but the answer to N54 tuning is not to go get a GTR.

        If that thing has 680whp or 644whp that mph is weak. Im sorry but it shoukd be much faster than that.

        Care made 627whp on sideline video.

        I don't get what the big deal is about criticizing the single, it has significantly bested the previous fastest 6mt in a short time vs the years the RB's have had. The single is just getting started you'd have to be retarded to think the RB's are comparable since this will certainly continue to improve pretty quickly vs the RB's which are probably close to maxed out.

        but the single is maxed out.. at 24 psi.. not the turbo, but fuel for it..

        reality. check -in some time people..

        the 6mt record was also with cobb tuning, not known to be aggressive. it is what it is. but what it isnt, is impressive for 24 psi and 624/644/650/680/700hp BT N54..

        On this board they were saying the fuel was close to maxed out six months ago when the whp was just over 500. Shiv still says he hasn't reached a fuel limit yet so I'll defer to the guy who has done it. Those who say it can't be done shouldn't interrupt those who are doing it.

        What makes you think that fuel is maxed out? According to the logs posted, he was hitting close to 24 psi, his AFR was dead solid at 11.5 and his short term fuel trims were no where near 34%. That would lead me to believe he can boost even higher and not be lean. Unless you are talking about fueling without meth, but it's hard to tell because you just made a comment without substantiating it with data/reasoning.

        The scaling is too small for me to read the log. I'm not sure why they bother posting them at all like that? But is he still claiming he has not reflashed the DME? I can't see fueling for those power levels happening without a DME reflash even with 4 methanol nozzles. Is he running a single meth pump or 2?

        It really is all about the money with you (Sticky: "and Vishnu is paying"). Your fact is Fiction, and your article shows that you act like a child. If you don't get the attention you are seeking you blast a perfectly good run. Its sad to say the least. The only drama and negativity on this site is you, karma is a funny thing and it always catches up to a person.
