    • First McLaren 600LT tuned on E85 by Dyno Spectrum - 661 rwhp

      Great ethanol tuning results on this 600LT from Dyno Spectrum. They state this is the first McLaren 600LT M838T tuned on full E85. The gains on the SSR Performance Mustang Dynamometer are practically unbelievable.


      The baseline is 513 rear wheel horsepower and 415 lb-ft of torque at the wheels. Yes, they picked up almost 150 rear wheel horsepower:


      That torque gain the mid-range? Almost 200 lb-ft at the wheels. Insane!

      They are using map switching software from M-Engineering and slots 1 and 2 are for 91 octane. Notice the pump gas tuned numbers on run number 2 which are not too shabby.

      Ethanol allows almost another full 60 horsepower at the wheels though.

      Excellent numbers from Dyno Spectrum.

        How much power does that badass roof scope add though?
