    • Bolt on C7 Corvette ZR1 LT5 with upper and lower pulleys hits the strip - 9.679@141.95 1/4 mile

      Finally we are seeing some times out of modded C7 Corvette ZR1's on the dragstrip. Remember, LT5 tuning is just getting going as the ECU was only recently cracked. That means you can definitely expect these cars to get faster and faster toward the end of the year.


      Mods:

      - Upper pulley
      - Lower pulley
      - Kooks headers
      - GM intake
      - Total Performance Racing tune

      They state it does over 900 wheel horsepower on C16 and BoostAddict is guessing they were not running C16 on these passes or the trap speed should be much higher.

      No slips posted unfortunately:

        Dave at DSX is working on flex fuel kit for these which will be a next big step since unlocking the ecu.
        Apparently the flex fuel logic isn't built into the E99 ecu like all the other GM ecu's where you could basically just add an ethanol sensor and change the tune.
