    • Further proof the S63TU twin turbo V8 loves methanol injection - F13 M6 667 wheel horsepower dyno

      However you feel about methanol injection there is no denying it provides a very nice octane boost. Guys with N54 3.0 liter direct injected twin turbo motors have shown the benefits of meth injection for years now when it is properly installed and maintained of course. The S63TU twin turbo direct injected V8 is showing similar benefits to meth injection as the motor clearly benefits from the octane increase showing 667 horsepower to the wheels.

      These results are very similar to what BMS hit with their F10 M5 which was 678 wheel horsepower using methanol injection although in 5th gear on a Dynojet. For now it seems the best bet for big power is a piggyback tune increasing boost with meth injection as an added safety mechanism to prevent detonation.

      It will be interesting to see how E85 benefits the S63TU as well as tuning evolves on the platform but if the N54 serves as precedent turbocharged and direct injected BMW motors love the cylinder cooling and octane benefits of ethanol and methanol.

      Dynograph below using a 50/50 mix of methanol to distilled water on 93 octane. This is the same M6 that went 11.0 @ 128 in the 1/4 mile recently:



      Baseline before meth injection:

        JB4 tune, catless downpipes, RPI intake scoops, meth injection, and K&N air filters.

        great , is the car tuned for the methanol ?

        In the sense of more boost with meth, yes. Nobody has full control of the ECU yet so it is not custom dyno tuned for meth, no.

        You want a setup that runs consistent at any temp this is the way to go! Love my setup! Thanks Terry
