    • Flash tuned BMW F97 X3M S58 hits 579 wheel horsepower with ethanol blend and 10.9 second 1/4 mile

      Nearly 600 horsepower at the wheels from the S58 with an early OTS (off the shelf) flash? Yes, the S58 is impressive indeed. We already saw some numbers from the S58 Competition version but the car here is a base F97 X3M.


      The baseline is lower at 459 wheel horsepower as measured on the AIM Performance Dynojet:


      STOCK 93: 459whp 429wtq
      STAGE 1 93: 551whp 532wtq
      STAGE 1 E30: 579whp 572wtq

      The tuned figures are huge and remember the base car and Competition cars will hit the same numbers with tuning.

      551 wheel horsepower on 93 octane pump is impressive but the E30 ethanol blend really opens eyes. This is an OTS beta file from PTF to boot so flash tuners will no doubt get more aggressive on E85 and race gas as time goes on and tuning evolves.

      As for the acceleration numbers, check this out:


      Very similar the JB4 tuned acceleration figures we saw from an X4M Competition.

      10's tune only from a six-cylinder BMW SUV... think about that.
