Owners who feel that said numbers are not enough in their Stingrays can easily increase output by means of a corn brew.
Paragon Performance offers a flex-fuel package developed specifically for the 2020 and newer Corvette Stingray, with said package delivering up to 500.25 horsepower and 486.45 pound-feet (660 Newton-meters) at the wheels rather than the flywheel.
The numbers in question are listed on Paragon's website. As for the car in the video attached below, make that 488 and 473 (641).
Compared to a baseline of 458 rear-wheel horsepower and 442 pound-feet (599 Newton-meters), the kit offers pretty solid gains.
Based in Iowa, the folks at Paragon advertise their E85 package at 4,699.99 buckaroos.
The kit includes an ECM unlock from HP Tuners, eight universal credits, an HP Tuners MPVI3 OBDII interface, and – of course – specific tuning.
Add to said items a set of corrosion-resistant fuel lines, a flex-fuel sensor supplied by GM's ACDelco, and a wiring harness.
Paragon says the kit can be furthered with a displacement-on-demand delete, along with a so-called burble tune for exhaust pops and crackles.
Although the latter is unnecessary, deleting the pesky Active Fuel Management feature sounds like money well spent.
Active Fuel Management implies four-cylinder operation, whereas the newer Dynamic Fuel Management is way more complex.
So complex that V8 engines equipped with DFM can save fuel by shutting off seven cylinders. A bit overkill, isn't it?
Considering that General Motors excluded AFM from the LT6 of the FPC-engined Z06, there is a reason why these fuel-saving technologies don't have a place in high-performance applications.
One could also make a case for dropping electric assistance from performance vehicles, but on the other hand, automakers were forced into making hybrid performance viable due to stringent fuel economy and emission regulations.
We also have to remember that an electric motor's near-instant torque makes a world of difference from a dig, with the plug-in hybrid 2025 BMW M5 coming to mind.
BMW claims 3.4 seconds to 60 miles per hour (97 kilometers per hour), but in the real world, the heaviest M5 yet achieved a simply ridiculous 3.12 seconds in the hands of Joe Achilles.
The C8-generation Corvette can be had with electric oomph as well, and later on, the Zora is expected to combine the ZR1's twin-turbo V8 with the E-Ray's front drive unit for a total of 1,200-something horsepower.
In the meantime, GM prepares to bring the 1,064-horsepower ZR1 to market, with the order books allegedly opening in February 2025.
As of this writing, the unassisted ZR1 is the most powerful series-production vehicle from the largest automaker of the Detroit Big Three.
As far as internal combustion is concerned, the C7-generation ZR1 previously held that title. On that note, the LT5 of the seventh-generation Corvette ZR1 does not feature Active Fuel Management either.
