Jeep 4.7L V8 Engine Performance
Making more usable power in a dayWe have been beefing up our ’01 WJ Grand Cherokee Laredo in the pages of Jp by adding suspension lift and bigger tires, a winch and bumper, and swapping T-cases and driveshafts. Despite all of this, we have not yet spent any significant time trying to get the 4.7L V-8 engine to make more power. Well, it’s about time isn’t it? The fact is that the ol’ WJ is pretty powerful, and while we have contemplated re-gearing the axles to pick up what little power and mileage the larger tires have sapped, it has not been one of our priorities…yet. Despite this we do believe that there is no such thing as too much power, and to that end we finally decided it might be time to see what a few simple mods could do for the Grand’s gasoline-burning mill. To show the results rather than just feel them, we got in touch with our pals over at Airaid Filter Company. Airaid graciously offered up not only a few goodies to help the Grand make power and torque (via one of its intake systems and throttle body spacers), but also some time testing parts on their all-wheel Mustang dyno. We also got to test out a spankin’ new TrailDash Jeep Tuner from Superchips to see what kind of horsepower and torque we could make with the 4.7L V-8. We made more power and significantly more torque lower in the rpm range. We also discovered a few more benefits with the installation of these parts. To see extra photos of the parts and a video of the WJ at speed on the dyno check out jpmagazine.com/wj_performance_extras.
