• 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'd love to see Mustang numbers for this car

        And, I'm sure Sticky would have a field day if the N54 blew up with the single even at these power levels Click here to enlarge must be hurting a DI platform is performing pretty well...i've always said, just give it a "chance" lol

        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.
        As much as I don't like how Shiv conducts himself for the most part, and I have seen him behave this way on other platforms in the past, you can't take away what he's done. Obviously the car is still getting dialed in. Sure everyone wanted him to just go out first try on a stock block and run 9's(Shiv included), but that obviously was not going to happen. I'm sure as these kits get into owner's hands, we will see great drivers hit some better times. I just think it's comical that when he runs a record time, you try to make it seem unimportant, because he didn't make the record by enough. I'm willing to bet that if you, or someone you like set an M3 record by .3 seconds, it would be front page news praising them, and having a million reasons explaining how the car is actually faster, but x, y, and z happened, so it wasn't a perfect run. This is my main BMW site, and I'm happy Burger customer for several parts on my car, but I just think in this instance the constant bickering and childish behavior makes this community look bad.

        Maybe I'm just used to the Evo community where a record was a record, and the only way to make it not important was to go out and break it yourself. AMS and Buscher in the Evo community were very much rivals and didn't get along, but they spoke with results in their cars, instead of complaining about how a run was done. I do agree that Shiv should do some runs on DR's in street trim, just to give a more realistic result, but most members on this forum have taken way more weight out of their cars than they would on the street and tried for glory times, so I don't see how it matters how a run was done. I'm sure you'll tear apart what I said somehow, but I just keep coming back to these threads for info, and all I see is bickering.

        Very well said b00st. If I could pos rep you I would. I agree this whole attitude has gotten old.

        It was nothing like this in the Honda realm either. We all have cool, fast 335's. Let's just focus on making them faster and cooler without the constant bickering. We join forums like this because we all bought the same car and want to be among our peers. It's upsetting that our community is full of hate and anger.

        I think it's safe to say at this point that the N54 platform is legendary and it has only just begun. It's going to be a wild ride from here on out.

        I agree, the car is definitely still getting tuned and he is still learning to drive. Here is the thing though: he is stirring up too much $#@!, he is building up too much hype and all this while he tries to discredit other tuners on other threads. That's 10000% duchebaggery! That's why we hate him! That's why we think he is a scumbag!

        A decent tuner and a decent person would keep their mouth shut and work on their project till it is perfected. Then and only then you go out and stir the masses.

        Do you see Cobb tuning publishing any dyno runs or videos during development stages? No! Do you see Apple sending out teaser shots for their upcoming iPad before it is actually revealed? No!

        EDIT:
        ...and don't even get me started on his Suspension package! This fool understands ABSOLUTELY nothing about suspensions!

        I totally agree. I am not a fan of how he conducts himself for the most part either. He's been around on other platforms that I've owned in the past, and it's just more of the same with this one. I was just addressing all of the other nonsense.

        Nobody is taking away anything by stating he is barely edging out the RB's and that for the WHP claimed the trap speed is on the low side. It is what it is.

        It was stated this is still a work in progress as it is.

        If you don't want to put things in context and simply look at a record as a record go ahead.

        Barely edging out RBs on an AT maybe, but that's not a fair comparison. He beat the fastest RB MT by ~0.6s I believe. The way you are saying it is misleading to those that don't understand the advantage in the AT. Let's at least call it like it is.

        Being the first is never easy and usually yields results that are lower than most expectations. I remember when my friend was trying to be the first GTR in the 9s way back in the day. He got into the high 10s fairly easy with his fully modded GTR and got to mid 10s, but struggled to get past that for while. Now, years later, getting into the 9s is much easier and low 10s can be done with FBO as he had back in the day.

        Progress will be made, but it's going to take time.

        It is what happened. I can't change it. Tell him to go run with an AT and we'll evaluate it again then.

        No, I mentioned this is still a work in progress and for what was shown with the manual the single turbo has not justified itself in comparison to what has already been done. Will we see more? I hope so. I am calling it exactly how it is and can't be faulted for Vishnu choosing to run a manual. I think that is just an excuse being used right now anyway that the AT must do better because the manual really hasn't shown us all that much over what already existed.

        Some questions to get an idea of what people may be thinking, and this is simply for curiousity purposes:

        1. If you only saw this slip and knew nothing about the car other than it weighed ~3400+lbs, what WHP would you think it makes? Please give an explanation of why.

        2. Knowing that this kit has put down ~640+whp (Not exactly sure of the numbers, but that should be close), what MPH do you think it should be hitting? Please give an explanation why.

        C6 Corvette Z06 will make about 460-470whp stock, and run 130mph 1/4. They weight about 3350 with average driver.

        I would guess around 550whp-560whp, based on my experience with my dynamometer, and realizing that there is turbo lag and he is not a professional drag racer/working on tuning. (Mustang Dyne)

        His 60' was good, so no traction excuse.


        2. Knowing that this kit has put down ~640+whp (Not exactly sure of the numbers, but that should be close), what MPH do you think it should be hitting? Please give an explanation why.

        It should hit around 140mph, based on what I have done simulations with in the past on the dyne. Since that 644whp was on a Dynojet, I expect more around 135mph.

        I'd guess around 520-540whp. One of Warren's 335s with around 500rw and more weight ran 11.1@129.x at Famoso. LM's 335 ran 11.0@127mph with around 480rw and a lot more weight.

        My brother has a C6 Z06 and I drag race against him every other week. He has never trapped more than 122.x. That is on a lot of passes. The couple 130mph posted on drag times must've happened when the stars aligned with an air pressure that would explode a normal mans lungs.

        Really? My friend with a blue 2003 C5 Z06 can trap that. Maybe a bad strip and he is shifting slow? Street tires? 93 octane?

        Def a bad strip. Stock tires, so traction problems there, yes 93 octane. And it's not that he is inexperienced. He would pull 1.5 60s on his 2005 SC'd Mustang GT all day and ran that thing down to an 11.3 I believe. Dyno'd a little under 500 whp (might have been detuned a little tho after that for street use) and was trapping around 120mph, give or take 2 mph on the day. Oh and our track here in Orlando will not open if temps go below 50. So retarded.

        I've seen about 10-15 Z06s at the track and they are all the same. Around 122 mph.

        I'd say thats a little bit of a low ball. I've seen many cars with that much power get nowhere close to 130mph, but I did ask for everyone's opinion so thank you for your input.

        I didn't know Hotrod had his car dyno'd. I always wanted to see what his curve looked like. Can you link me to the thread?

        I thought it was common knowledge that DynoJets read high?

        I always thought Dynojets were more accurate for power at the flywheel. In Shiv's case, 625 on a dynojet would equal about 532 on a mustang dyno (15% loss), which would be right around a 10.8 1/4 mile and 132 trap speed.
