    • The BMW N54 hits a new peak horsepower record at 753 WHP with a custom Precision 6466 top mount setup

      Congratulations to BimmerBoost member aflatau who managed to improve on his previous 701 wheel horsepower pull with a a 753 wheel horsepower pull setting a new peak N54 horsepower record in the process. This exceeds one of the previous N54 horsepower records set by Vargas Turbo Technology at 725 wheel horsepower. It is important to note that this record was set on a Dynomite dyno while Vargas used a Dynojet.


      Why this is important is because the Dynomite tends to read higher. Obviously people understand that 753 wheel horsepower is a higher number than 725 wheel horsepower it is entirely possible the Vargas car would show more power if measured on the same dyno at the same time. This is one of the problems with comparing figures from different dynos with so many different dynamometers in the world there is no single standard that works across the board for everyone.

      Regardless, this is a new peak horsepower record and hopefully we can compare Dynojet numbers to Dynojet numbers to get a better idea. The truth is power between the top N54's is very similar at the moment. Congratulations to @aflatau for pushing the limits with his custom setup and BimmerBoost is happy to have played a small role in this achievement with the use of the BimmerBoost flash software making it possible.

        question about the map sensor limit.. how is 29PSI the limit, 3.5 sensor should be able to read about 36psi? (2.5 psi boost).. or is it more like a 3bar sensor in reality?

        Not sure on that one, Terry@BMS would know more about that.

        I have always wondered the same thing. @Terry@BMS Can you chime in? @aflatau, There are 4 and 5 bar map sensors from GM AFAIK. Should also be PNP, but I hear those are like 300 each sensor or something. Not too sure though.

        IIRC it was like 100$ for the sensor. and i believe sarcasm was part of the 4-5 map sensor quote lol

        Anyways CONGRATS!!

        Kickass! Congrats man. And no offense, but I hope this falls quickly, either by you or another pioneer of the N54 platform.

        The 3.5 bar will read up to ~36psi. When we did the programming I capped it at 29psi for various programming reasons. I figured I wouldn't have to worry about it for a few years. Guess again. I'll look in getting that 29psi up to 36psi. Click here to enlarge

        Nothing like writing "bimmerboost" on that other site - haven't seen that many asterisks since Lance Armstrong was outed for using performance enhancing drugs.
