What would possess someone to create a Corvette with over 2,200 horsepower? Does it really matter? With an amazing feat like that, we didn’t think so. Take a look at the unbelievable Top Speed C5 Z06 that has over three times the amount of horsepower as a modern ZR1 at the April Ohio Mile event in the Wyldfantasies Media Studios video above.
Built by Hinson Motorsports, “Record Hunter” is among the most powerful Corvettes we’ve ever seen and there’s reason for that. Bringing the car to its astounding 2,246 HP rating at 7,800 RPM is a massive build the crew completed back in March.
Under the car’s hood you’ll find a 427 cubic inch RHS Aluminum Tall Deck Block assembled and machined by Butler Performance. Stuffed inside this block are aluminum connecting rods, Diamond pistons and a Callies Ultra Center Counter Weight Billet Camshaft, as well as a custom high capacity oil pan from Doug Lee Engineuity.
Making up the engine’s top end are TEA-ported Trick Flow 245cc heads, Crower roller rocker arms, COMP Cam pushrods, a custom COMP solid roller camshaft and a GM EFI carb-style intake manifold. But these components alone aren’t what gives Record Hunter its massive amount of horsepower.
That extra boost comes from an intricate custom turbocharger system featuring a 118mm turbo, custom air to water intercooler, Tial wastegate and blow off valves, and a 5-inch downpipe all working to the tune of 34 PSI manifold pressure.
Of course, a build like this makes for extra fuel needs, which the team has dialed in using a Holley Dominator EFI system and Bosch 160 pound-per-hour injectors, as well as a regulator and fuel pumps from Fuelab.
The whole build is backed by a RPM-built TR6060 transmission with a SPEC twin disc clutch and an RPM ZR1 differential with Quaife LSD.
Surprisingly, the Corvette looks relatively like the C5 production car it started out as, minus the modified hood, roll cage and custom adjustable rear wing, of course. But obviously, looks can be deceiving. And 18-inch wheels from True Forged Wheels wrapped in Hoosier R6 rubber make sure that as much of Record Hunter’s power as possible is delivered successfully to the ground to turn heads like no other C5 can do.
After completing the build in March, the Hinson Motorsports crew took Record Hunter to the Ohio Mile, an East Coast Timing Association event in Wilmington, Ohio on April 29th to see what it could do. As the first standing mile event the Corvette raced at since its build, the April Ohio Mile proved to be a great tuning opportunity for the crew since the mile race was speed-limited to 150 MPH.
It may not look too far off from stock, but Record Hunter packs nearly 2,000 more horsepower than a stock C5 Z06.
As the car’s name suggests, future goals for Record Hunter are to set new standing mile records. With a car potentially capable of topping out at over 250 MPH, we’re sure Hinson Motorsports will be making history with the car this season. Be sure to watch out for Record Hunter at any of the standing mile events this year.
