    • 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 did see on E90 that sikh335 had trouble pulling a GTR from a roll... first he claimed it was stock, now he says it has unknown mods. REALLY interested in seeing some 60-130 times.

        They don't use Delrin or urethane in their pro cars, but they may have in the past. Delrin does not allow more than one axis of movement, and they need full balljoints. The bolts will strain and break. It's a mistake that several of the teams made when they first raced the E92s. Fall Line has a full upgraded upright where they custom weld double-shear ears onto the upright to 2 of the 3 single-shear mounts. Requires lots of custom parts, but they don't break under pro race conditions.

        Might I ask, do you have a 10-second or low 11 timeslip? Awful lot of negativity spewed from someone who doesn't even have a dog in the fight.

        He pioneered the N54 to low elevens and held the record for quite awhile...

        Lol, yeah he does... and he achieved similar numbers with much less effort and cost.

        LMFAO! James you always have some very technical knowledge of the N54 that is greatly appreciated on this forum, but LM had THE FASTEST N54 in the world for a while. 11.1 ET if i remember right. Like Q4P stated, without spending $10k on a single turbo kit. That's why we're a little skeptical of the $10K price tag and the underwhelming results on the drag strip on this forum. We are by no means fanboys here, more like realists. Some people on here are vey anti-shiv for their own personal reasons, but we're not procede bashing. Single turbo bashing really, from people with the fastest, most powerful N54s around.

        its tough to pull a gtr, when your car is slower than a gtr i guess

        Hey guys, just settle down, I may have sounded a little condescending but wasn't my intention, just wanted to get some background. I haven't been in the N54 world for long, so I am not aware of LostMarine's history.

        I, however, agree wholeheartedly that a high 10s run with 27" drag slicks is hardly earth-shattering. I have a feeling that a better launch will get much better times, and the 335 is decidedly handicapped against a 135 due to weight. Put the single turbo in a 135 and retest against the "fastest N54s" which seem to all be 1 series.

        But seriously, there's only a handful out there, and only one 335i has been taken to a 1/4mi by Shiv, who may not be the best candidate to pilot a drag car. All this bashing on the perceived lack of performance in the 1/4mi doesn't say anything else about the way it performs on higher speed runs. Not everyone who got the single kit so far is an avid drag racer that simply cannot get a 10s timeslip and is being censored by Shiv.

        The ShiftSector event where Shiv put upgraded twin-turbo N54s so far in his rear view mirror shows what the car can do. The 1/4mi is just as difficult of a challenge for the driver as it is for the car, and some people have it, some don't.

        @JamesM3M5, I just wish I could ever pull off that 1.57 60' that Shiv got on his 10.8 run. Mine's an E90 6MT and on my 11.43 run I had a 1.8 60', 126mph trap.

        Without touching the tune at all and just dropping down to his 60' this same car had a 10.99 in it. One can dream Click here to enlarge

        1.57? I don't remember that at all. I though his 60' sucked? No? $#@!, my memory must be fading.

        @LostMarine 's 1.7 60' if it were down by 0.12secs he would've been in the 10s too, same tune same car no other mods.

        It would be nice to see some other data from single turbo guys....shiv also had a different rear ratio in his car, not sure if that's worse or better. From the data we see so far, who would buy a single over the rb's.? The title of the thread really isn't that far off, so far it is underwhelming IMO.

        The only thing that his 3.46 diff impacted was launches got even harder to pull off. Thus the slicks in the end. Given his 1.57 60' he was only helped by the 3.46 gearing.

        I'm going the other way, taller not shorter, to a 2.56 on my car. This will eliminate the 3-4 shift entirely and allow the car to finish the 1/4 in 2 shifts which on its own should shave the time down by 0.3secs at least due to on/off loading, unless the gearing ends up slowing me down in return. It "should" also allow for a more usable 1st gear.

        i just think that if I really wanted a 10 second car I'd just buy a GT500 or slap a SC on a new 5.0 mustang. I love my 335i but I just don't see dropping $10k into an I6 to run 10.822@131. Everyone knows that 335i suck at drag racing (especially me), I just don't see the point of losing the DDability by going single turbo and coming out with a 10.822 car. What other reason is there to own a 650 HP 335i? I'm interested to see what Mat Morkin can do with these TT upgraded manis, but until then I think I'll just put a .30 shot on the car and shoot for 10s that way. LOL
