    • The 2019 C7 Chevrolet ZR1 Corvette LT5 makes almost 100 more horsepower at the wheels than the C7 Z06 LT4 and 150 more than a C6 ZR1 LS9

      The 2019 C7 Corvette ZR1 LT5 is rated at 755 horsepower and 715 lb-ft of torque. How is this output achieved? A dual-injection fuel system and a bigger blower play the major roles. It shows compared to the C7 Z06 LT4.


      As a refresher, the C7 Z06 LT4 produces 650 horsepower and 650 lb-ft of torque. The supercharger is an Eaton TVS1740 unit. Arguably, too small for the 6.2 liter V8. That does not stop it from making massive horsepower and torque though.

      Oh, and just for fun a C6 ZR1 LS9 is overlaid on the LT4 graph (check out a past LT4 vs. LS9 comparison article):


      The Eaton TVS2650 on the LT5 makes the LT4's blower look like the baby it is. Just look at how much better the top end curve is plus keep in mind it has more tuning headroom:


      167 more lb-ft of torque at the wheels than a C6 ZR1. 83 more lb-ft of torque at the wheels than a C7 Z06 LT4 but with much better breathing up top for a stronger horsepower curve toward redline.

      You can even say it is slightly underrated and delivering closer to 785 horsepower.

      It's a damn monster.
