GM Authority initially reported on Lingenfelter’s upcoming supercharger upgrade for the Chevy Blazer crossover in December of 2019. Then, last week, we were the first to bring you further details about along with the very first photos of the vehicle. Now we can exclusively show the first installation of the kit in our exclusive video.
The clip shows the Eaton R1740 TVS supercharger mounted to the 3.6L V6 LGX gasoline engine, which the Chevy Blazer produces 308 horsepower and 270 pound-feet of torque in stock form. Starting at the air filter on the passenger side of the vehicle, a large pipe leads across the front of the engine, then turns across it at around the mid-point of the V6 before heading back in the original direction.
A further turn allows the pipe to enter the intake side of the Eaton unit, where air will be compressed. The engine will therefore produce far more power than stock.
Exactly how much more has not yet been confirmed, but Lingenfelter’s initial estimates put total output at around 450 crank horsepower. That’s an increase of 46 percent over the standard figure.
The Eaton R1740 TVS is the same compressor used for the supercharged 6.2L V8 LT4 engine, which GM has fitted to the Chevy Corvette C7 and the Chevy Camaro ZL1. It will also be used in the upcoming 2022 Cadillac CT5-V Blackwing ultra-high-performance luxury sedan.
Lingenfelter already uses the Eaton unit for another supercharger kit, one designed for the 3.6L V6 LGZ used in the 2017-2020 Chevy Colorado and GMC Canyon pickup trucks. Although those vehicles also have a V6 engine, the kits are quite different because of the powertrain orientation: longitudinally in the trucks and transversely in the Chevy Blazer.
The 2021 Chevy Blazer is also available with the naturally aspirated 2.5L I4 LCV engine, which makes 193 horsepower and 188 pound-feet of torque, and the turbocharged 2.0 I4 LSY, which is rated at 227 horsepower and 258 pound-feet of torque. The Lingenfelter kit will not be suitable for either of these motors, as it’s developed specifically for the atmospheric six for the 2019 and newer Blazer.
