When 707 Horsepower Just Isn’t Enough
Thank goodness Livernois Motorsports has developed performance upgrades for the 2018 Jeep Grand Cherokee Trackhawk. Owners currently have to suffer with a mere 707 horsepower barely dragging them to 100 km/h in a sluggish 3.5 seconds. What I mean to say is why settle for quick when you can have acceleration that’s the equivalent of teleportation. The performance upgrades offer power increases of up to 250 horsepower and 205 lb-ft of torque for the supercharged SUV.
Livernois says, “Three Trackhawk packages are available to improve all-around performance with enhanced throttle response and greater power. Each features PCM unlocking service and dyno-proven air and fuel adjustments, along with an EvenFlo Thermostat, Innovators West harmonic balancer upgrade with an overdrive crankshaft pulley, Innovators West crankshaft pinning system and a new serpentine belt. Installation and custom dyno tuning is performed at Livernois Motorsports' facility in Dearborn Heights, Michigan, and comes with a one-year warranty.”
"We're proud to lead the industry with engine upgrades for the 2018 Jeep Grand Cherokee Trackhawk," said Tom Millen, general manager for Livernois Motorsports. "We created these systems to be easily installed and deliver uncompromising drivability, along with their tremendous power increases."
The three package levels, which should be named after the Spaceballs movie trope, Light Speed, Ridiculous Speed, and Ludicrous Speed, include:
S900 ($3,749): +135 hp / +135 lb-ft - In addition to the content and services mentioned above, the S900 package includes Injector Dynamics ID1050X upgraded fuel injectors.
S975 ($4,449): +200 hp / +175 lb-ft - The S975 package adds the Livernois Powerstorm Supercharger Pulley to help increase boost, as well as Injector Dynamics ID1050X upgraded fuel injectors, increasing horsepower to more than 900.
S1025 ($5,649): +250 hp / +205 lb-ft - A Flex Fuel upgrade to E85 capability complements the Livernois Powerstorm Supercharger Pulley and Injector Dynamics ID1300X upgraded fuel injectors to push the Grand Cherokee Trackhawk's output to nearly 1,000 horsepower.
