YouTube’s StreetSpeed717 is the proud owner of a C7 Corvette ZR1 with a highly modified 6.2-liter LT5 V8 built by Late Model Racecraft. His Corvette ZR1 is good for around 1,000 horsepower at the crank and he has so far gone undefeated in the various unofficial roll races he has participated in with the car. So when the owner of a 1,200-horsepower 2020 Mustang GT500 recently challenged him to a roll race, he was a bit nervous that this record-setting pony car was going to the be one to break his winning streak.
Despite being down on power to the Mustang, StreetSpeed717’s C7 Corvette ZR1 definitely has the right hardware to hang with this nitrous-fed GT500. The Corvette gaps the Mustang in every race where it’s not on nitrous and when the owner does turn the bottle on, the finish is pretty much too close to call. We know the Corvette is lighter than the Mustang, but we really thought it would have had this race in the bag given its massive power advantage.
It’s worth pointing out that this C7 Corvette ZR1 appears to be equipped with the ZTK Performance Package, which adds a rear wing and front splitter that increases drag on the car and can slow it down in a straight line. It may be even faster in the top end of the race if it was running the base-spec aerodynamics package with the low rear wing. Also hampering the Vette is the transmission, which slips badly in fifth gear. This is an 850-wheel-horsepower car on a stock transmission, though, so perhaps it’s not surprising that the eight-speed automatic has seen better days.
