• 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'm not you and I'll continue to do as I see fit with my things and you do what you want with yours.
        I really wish you the best of luck that the build turns out how you want it to. But I can't understand why you don't raise hell at the shop to make your car a TOP PRIORITY!

        I will go about it my way. This is OT anyway, the only reason it was brought up was for somebody obviously with little knowledge attempting to discredit me by changing the subject to me instead of Vishnu barely stumbling into the 10's.

        I don't see how I am trying to discredit you at all. I was simply calling you an ass. As for shiv's car...it's faster than yours. So, that should be enough...if you weren't the one that is bitter because his car runs, and runs quick.

        As for me? I have an 07 335 e92. It is currently my only car and is still on stock turbos. So, it's certainly not fast, and I don't care. I've been enjoying it since I bought it, and will enjoy it even more when the stockers are gone for something with external wastegates. Not to mention, you of all people should know that my join date isn't exactly recent. I just chose not to post until now.

        You obviously have no idea what you're talking about.

        Then I'm not quite sure why you are asking such basic questions such as what I drive and seem to be uninformed about Shiv's behavior here. Sounds like you need to do some more reading.

        So I've been following some of the posts on the new single turbo set up and my opinions are as follows:

        It is not really designed for autocross/ road course racing. More designed for 1/4 mile times and street
        If the time info is true, congrats on getting into the 10's
        There has always been missing information from the producer of the kit when people are interested in details
        Fueling is guessed at but never verified from the producer.
        It's easy and comical sometimes to read all the BS that comes along with these threads and not everyone has to be a mechanical engineer to see what is BS and what is fact.

        Thanks for posting Sticky.. Click here to enlarge

        Could be me & the fact I am banned from E90 but I have not seen much if anything listing results from the guys who have installed the kit. Anyone see any times posted anyplace?

        We only have the times Shiv hand picks to release, that's it.

        So far, the customers who have had the kit installed have been driving their cars every day and not racing them. We haven't had any mechanical issues with any of them regardless of what the current rumors are.

        Everyone is entitled to their own opinions, and I'm not here to argue or go against the status quo, I just felt I would add some additional information in.

        I will be Vboxing mine next week some time. Will post 60-130 numbers as well as Vbox 1/4 mile numbers. I dont plan on hitting Sacramento Raceway until it cools down its 95 degrees in Sac today and today was a mild day.

        Show us what it can do in the summer. I ran in the summer at sac, why can't you?

        +1 DA may hurt turbo cars, but nowhere near the impact it has on an NA motor.

        Just do it for fun, what's the worry? At worst you will trap 127-128.

        he's afraid. he has to wait for optimum conditions and shiv to be available at the track, to show what it can do in the real world, from an average customer..

        If he runs poorly Shiv won't let him post the slip anyway. He keeps his girl on a tight leash.

        Tough crowd. Guess you can't say anything good about Vishnu products on this forum. Can't wait for the results Sikh, enjoy the powa.

        You can say good things about Vishnu products. It's how you say it.

        Sikh essentially drools Shiv's man juice all over his keyboard as he types and spits it in the face of anyone who doesn't do the same. A little different.

        Plenty of Procede owners who get along with people here.

        Consider a supercharged M3 then.

        Kidding. Kind of.

        We will see this eventually just don't hold your breath. Would be really cool to see some bigger twins. The N54 seems to be built with higher compression and quicker spool down low. It may be best to accentuate the factory curve. The single turbo just isn't doing what I expected yet.
