New Magnuson Supercharger Pushes LT4 to Make 1,200 HP
Bumping up the blower displacement by almost a full liter is one of the tricks Magnuson used to increase the LT4 motor’s output.
The LT4 engine is the latest pure performance product to come out of GM since the coveted release of the LS9 (along with the LT5). The LS9 was praised for cutting no corner in its use in the C6 ZR1, having incredible forged components and state of the art technology all around. However, GM and Chevy are not ones to stop improving a product and making technological progress. The LT4 is based off of the same small block as the LT1 found in the Stingray C7, which has made several technical leaps since the dominance of the LS-based platform, such as cylinder deactivation and direct injection. However, obvious improvements have been made to the LT4 compared to the LT1 in order to handle the increased pressure made by applying boost.
Obviously, the 650 HP and 650 foot pounds of torque made by the LT4 are no joke and honestly, might already be too much power for most applications. But, when has horsepower ever been about reasonable application? That’s when Magnuson Superchargers stepped into the arena. They recently adapted to make a new supercharger setup for the already powerful LT4 engine. Taking a look at Magnuson’s website, we learned a little bit more about what this new blower is about.
To start, this new supercharger is known as the TVS2650R and it uses similar components as those found on the LT5 supercharger powering the C7 ZR1. However, this supercharger still has .05 more liters of displacement compared to the unit used on the ZR1. Considering that car makes an easy 755 HP, this supercharger must be able to output some pretty crazy power figures. According to Magnuson, this blower will be able to fit under the hood of a LT4-equipped vehicle without modification, even with its larger than stock sizing.
Considering the fact that this blower will make somewhere in the range of 1,200 HP, it’s safe to say that some additional supporting mods will be required to reach anywhere those power figures. Obviously, this level of power comes with a price, $5,995 to start for the basic package featuring a 90mm pulley and inlet. Nobody has ever thought making 1,000-plus HP was cheap.
