This component will also be important later on down the line as we progress through stages 2-4 and need to tune accordingly. With all the pieces in place, there’s just one thing left before we head back to the dyno…Ī major part of the Corvette Central Performance Stage 1 kit is the included FAST flash tuner, which we used to reprogram the PCM to take full advantage of the new, less restrictive intake tract. The final piece of hardware in Stage 1 is the throttle body coolant bypass, which is a simple barbed fitting that connects the feed and return coolant hoses together to help prevent the throttle body from warming up – Since we’re in SoCal, a frozen-shut throttle blade isn’t a real possibility. To confirm our findings, we also took Y2k to the dragstrip and made a few laps – while the engine was healthy, our rusty manual transmission launch technique left much to be desired, and the best we could do with an abused stock clutch was 13.480 at 105.43 – even with street tires and a slow 60 foot, a result that put us at the upper end of what an internet search would say is possible from a stock LS1-powered C5. So, imagine our surprise when our Dynojet (which has proven to be both accurate and repeatable with the scores of cars we’ve tested here at powerTV) reported 317.79 horsepower and 334 pound feet of torque – very, very healthy for an 11 year old bone stock LS1 with 50,000 miles on the clock. That’s consistent with the numbers you’ll find online for a stock C5 M6 – something between 290-315 horsepower at the tires. The 2000 Corvette was rated at 345 horsepower “at the brochure,” and based on the generally accepted 15% loss through a manual transmission, with a certain amount of hand-waving we arrived at an expected rear wheel horsepower number of something around 293. ![]() Follow along as we turn our decade-old project Corvette into a snarling hot rod that will outrun a stock LS3 C6! In this two-part series, we’ll show you where we started, do stages 1 and 2 with trips back to the dyno between each stage, then head to the dragstrip to get some real-world performance numbers. As with every other product we sell, we source our performance products with the question ‘Would I install this on my own car?’ in mind.” We’ve spent a lot of time researching and developing the product mix on Corvette Central Performance. The C5 performance packages are a great example of this. With this in mind, we want to eliminate the guesswork for late model Corvette owners who are searching for increased performance. ![]() ![]() “But depending on the combination of parts ultimately selected, performance can either be improved or hampered. “As our website demonstrates, there is an impressive array of performance products available for Corvettes,” he explains. Per Corvette Central’s Matt Gessler, creating the new performance brand was the next logical step. All the stages use top quality parts from suppliers like Corsa, COMP Cams, and MSD. The idea behind their packages is to take the guesswork out of beefing up your 1997-2004 Corvette with upgrades that have been dyno-proven and build upon the previous step. As with every other product we sell, we source our performance products with the question ‘Would I install this on my own car?’ in mind.
