In the world of aftermarket tuning, few names are as respected as Lingenfelter Performance Engineering. Specializing in General Motors vehicles for over 46 years, owner Ken Lingenfelter and his team are known for superb engineering and big power from its products. While they are mostly known for their work with Corvettes and Camaros, LPE hasn’t been shy about modifying trucks and SUVs. This trend continues, as Lingenfelter has just announced their newest performance package for the Cadillac Escalade and the GMC Yukon Denali equipped with the 6.2L L86 V8 engine.
The new kit is designed for the K2 platform Cadillac Escalade and the Yukon Denali produced between 2015-2019. The same can likely be said for the Chevrolet Tahoe and Suburban equipped with the RST Performance Package, which unlocks the 6.2L V8 for both Chevy SUVs.
LPE takes the stock 6.2 liter V8 found in both trucks starts by adding a Magnuson TVS2300 intercooled supercharger system, which is based on the Eaton blower found atop GM’s own LT4 V8. Other modifications include Lingenfelter CNC ported cylinder heads, Lingenfelter dual valve springs and titanium retainers, Lingenfelter supercharger camshaft by Competition Cams, and the direct injection system straight off the LT4 supercharged V8 found in the Camaro ZL1, C7 Corvette Z06, and Cadillac CTS-V.
All of that goodness comes together to produce 700 horsepower 665 pound feet of torque. Those figures represent gains of 187 horsepower and 153 pound feet at the wheels. Check out the video below:
While the kit allows owners to make their SUV more powerful than the Corvette Z06, not much is lost in the way of usability. The kit does delete the factory active fuel management and variable cam timing systems, but Lingenfelter says highway mileage not adversely affected by the added power. That is likely a result of the custom engine control module reprogramming that the package also includes.
Every LPE-tuned vehicle undergoes chassis dyno testing before and after kit installation, and is backed by the company’s 3 year/ 36,000 mile warranty. Big power does come at a price though, which is $16,685.00 for this particular set up. While that is not cheap by any means, Lingenfelter does maintain a great reputation in the industry for their products and services. While General Motors doesn’t offer up a Jeep TrackHawk rival from the factory, it is nice to know that Lingenfelter has Cadillac Escalade and GMC Yukon Denali owners covered.
While there is an LT4-powered Cadillac Escalade coming for the next generation model, who wants to wait when Hellcat-rivaling power is up for grabs now for the current one?
