Camaro | Chevrolet : April 10, 2019
It goes without saying that the 650hp/650lbft LT4 engine found in the C7 Corvette Z06, Gen-VI Camaro ZL1, and V3 Cadillac CTS-V is an absolute beast of a power plant. The only drawback? The OEM supercharger is on the smaller size (1.76L), and is already rather highly spun from the factory (~20,000rpm). While there is definitely performance to be had by modifying the factory supercharger (pullies, porting, etc.), there's a far more direct path to 700whp+... direct-fitment 2.9L twin-screw from Whipple Superchargers!
And this is exactly what this customer brought his 2017 Chevrolet Camaro ZL1 in for! The baseline alone at 578.60whp & 568.56lbft through the 10L90E automatic transmission with only a Roto-Fab, LLC intake system was already an impressive starting point, but after the Whipple installation and a custom calibration by Vlad via HP Tuners, this LT4's output jumped to 700.96whp & 682.72lbft! That's 122.36whp & 114.16lbft increase!
Long-tube headers and a bit smaller pulley will really set this setup off, but for the time being, we think he should enjoy the new performance.
