You’ll recall GM’s supercharged, 6.2L LSA V8 as the engine that powered the previous-generation Cadillac CTS-V and Chevrolet Camaro ZL1. In the CTS-V, it had an output of 556 horsepower and 551 lb-ft of torque, while the ZL1 saw slightly more power with 580 horsepower and 556 lb-ft.
As impressive as both iterations are, they’ve got nothing on the LSA in the video above, which was massaged Lingenfelter Performance Engineering, to put out an astounding 900 horsepower.
From the factory, GM’s LSA utilized a 1.9-liter, 4-lobe supercharger from Eaton. This LPE-built motor does away with the factory blower, using a Kenne Bell unit of unknown size in its stead. It’s fair to assume that the aftermarket supercharger is a fair bit bigger than the stock one.
This engine was built for use in Snakepit Custom’s first-gen Pontiac Firebird – a pro-touring project car that will couple the 900-horsepower engine with a 6-speed sequential gearbox. The build is currently underway, and we can’t wait to see the final product.
Until then, enjoy the roar of this big, bad, blown V8.
