East Coast Supercharging’s Twin-Turbo C8 Makes Big Power With New Controller
After 18 months of testing, ECS hits the dyno and cranks up the boost on their twin-turbo C8 with impressive results.
We’ve been waiting a couple of years now for someone to crack the C8 Corvette’s “uncrackable” ECU, and yet, not one has accomplished that daunting task as of yet. Now, with news that GM won’t be helping (most) aftermarket companies accomplish that task, those of us that want more from our C8s will need to get creative. Thankfully, East Coast Supercharging is putting in the work with their own twin-turbo C8 Corvette build, which recently hit the dyno with a brand new Peitz Performance controller and a complete Pro Meth direct port injection setup.
ECS installed the twin-turbo kit on their C8 a couple of months ago, but to date, hasn’t been able to go for a max power run without worrying about grenading the LT2’s stock bottom end. Thanks to their latest combo, that’s now possible, so we get to see what the car is truly capable of. And as we can see in this video, the results of their hard work are clearly paying off as the company continues to develop its production twin-turbo C8 kit.
ECS’s prototype twin-turbo kit consists of a pair of mirror-image Precision Turbo 6266 hairdryers, which are currently pumping a modest 11 psi of boost into the Corvette’s LT2 powerplant. In addition to the aforementioned controller and meth injection, the C8 has also been treated to Late Model Engines CNC ported heads with upgraded springs and a Head Games Motorsports ported intake manifold and throttle body. The dual-clutch transmission has been fortified with a Dodson Motorsports Super Stock Stage 1 clutch, while Driveshaft Shop axles shore up a notorious weak spot.
The result of that combination are some truly impressive numbers on this latest dyno run – 836 horsepower and 791 pound-feet of torque at the wheels. After 18 months of development, it’s no surprise ECS is quite pleased with the outcome. “We’ve been driving it and testing different things,” ECS says in the video. “We’ve been looking to come up with a good tuning solution for it. We’ve been working with the guys over at Peitz Performance, getting this controller dialed in, and the initial results are a little higher than expected.”
ECS plans on turning the boost down on their base kits to around 6 psi to keep the LT2’s internals safe, and offering more in conjunction with port injection. But these are truly promising numbers that give C8 owners some hope of safely modifying their cars to make more power, even though GM has gone out of its way to make that difficult in the name of protecting the newest Corvette from hackers.
