• 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 sadly didn't buy vargas III i meant as in I'm waiting for slips from users who choose to run at the strip. my pocket likes to live bi-curiously sadly till it starts getting fatter

        He's been down for months and had a core engine months before that? I guess things always take longer than expected. I still haven't pulled the head on my old motor to check for block damage. My excuse is I left it at a shop to handle and one of their mechanics left, so they've not had the staff to look at it yet. Click here to enlarge
