    • Doc Race Precision 6266 single turbo automatic E82 135i N54 putting down 761 rwhp on E85

      While there are those chasing dyno numbers there is definitely a sweet spot for the N54 to make power reliably. That spot is even more narrow for automatics but this one is holding up quite well at what is an impressive 761 rear wheel horsepower.


      The curve itself from 4500 to 7000 is fairly nice:


      This car is on port injection with E85 and a Doc Race single turbo kit running a Precision 6266 turbocharger.

      Can you go beyond this? Sure, but 761 at the wheels is a ton of power in the lighter E82 chassis and you will run into driveline and motor problems if you get greedy.

      It's more fun to drive the car reliably with this kind of power than chase numbers on a dyno and run into problems.

        Not sure. Maybe @DOC_Race knows?

        And for us who like to get more than 120 miles on a tank, is there a pump gas graph?

        Not my car, but the tuner told me it was on 30psi.
