If you’ve been carefully following along the race for various milestones in the new direct-injection 2014 Chevrolet Corvette Stingray, then you’d know that some of the usual suspects on LSx scene were pushing the limits. Quietly, though, in the background, Vengeance Racing was lurking like a ravenous wolf.
In January the crew from Cumming, Georgia built what was at that time the most powerful C7 in the world, making 739hp and 739 lb-ft of torque using a Nitrous Outlet kit, American Racing long-tube headers, and a Vengeance Racing-spec camshaft.
A month later, they used an ECS supercharger kit to make 832-rwhp and 762 lb-ft of torque.
But that was all small potatoes compared to their next venture – a custom twin-turbo system that would make 1,018-rwhp and 894 lb-ft of torque at only 14psi, with help from a 100-shot of nitrous. While “most powerful” records usually don’t last long, there can only be one “first.” And Vengeance lays claim to the first 1,000-rwhp C7. If that isn’t epic enough, check out the tribute to sexy ride-along videos.
With the direct-injection system presenting unique challenges – namely no aftermarket injectors or fuel pumps – many thought this mark may have been impossible to achieve. Throw in the added difficulty of tuning the new ECM for boost, and it seemed a herculean task, which is most likely why few of the turbo C7’s you’ve heard about have actual dyno slips at this point. Stay tuned for more as we learn about the new Gen V engine and the C7. And for those of you wondering, as of yet there have been no issues with the stock LT1 bottom-end, transmission, clutch, or differential according to Vengeance.
