The stock 5.5-liter LT6 V8 engine that powers the Corvette Z06 already makes 670 horsepower. The flat-plane crank allows it to reach a high redline of 8,600 rpm, and Cicio Performance's package boosts it even higher."The C800 package was engineered to unlock the untapped potential of the C8 Z06 while maintaining the drivability, reliability, and refinement expected from a factory-level experience. Designed around the limitations of the stock fuel system, the C800 package safely and consistently delivers 800+ horsepower using the factory engine and transmission," said Cicio Performance in its Instagram post.Drivability and ReliabilityAn increase of 130 horsepower might not sound that great, but considering that Cicio Performance prioritized drivability, reliability, and refinement says a lot about this kit. Owners who want to buy this kit only need to purchase it. The kit is designed to work around the stock limitations of the engine, transmission, and fuel system, so if you want 800 horsepower, then it's just gonna be one big bill, and you're done.AdvertisementAdvertisementSpeaking of which, Cicio Performance priced this kit at $39,995, installed and tuned. What's more, the brand is offering its first five clients a discounted price of $37,500. There's no need to change out the internals of your engine or beef up your transmission.Considering the complexity of an aftermarket turbo kit and the amount of work it takes to ensure safety and reliability, $39,995 seems like a good deal. Turbo kits tend to be expensive because they're not all self-contained. The system is intercooled, has two turbos, includes a matched Cicio-spec exhaust system, and has software and tuning done via HP Tuners.Corvette Blogger secured the dyno sheets for this kit, which max out at 810 horsepower and 637 lb-ft of torque.Cicio Performance'Just' 800 HorsepowerIt might not seem worth it at first, but who's to say that there isn't a 'stage 2' over the horizon with this kit? Cicio mentions that the package accounts for the limits of the stock systems, but is there additional performance that can be unlocked?AdvertisementAdvertisementCould this mean that with a few more choice upgrades, more performance can be extracted? Perhaps an upgraded Z06 with additional improvements could match the Corvette ZR1, which makes 1,064 horsepower or more with a tune. Plus, considering that the Z06 can be had for about $80,000 less than a ZR1, the $40,000 twin turbo kit doesn't sound too shabby.What I want to know now is whether or not Cicio's performance has other plans for this kit. Will it make hybrid horsepower figures with the right improvements? Or will going overboard simply wreck the engine and transmission?Cicio PerformanceThis story was originally published by Autoblog on Jun 7, 2026, where it first appeared in the News section.
