Tuned Jaguar XJR Shows the Potential of Its Supercharged V8

By -

Jaguar super-sedan picks up big power with a new pulley, intercooler exhaust and a tune.

The current Jaguar XJR with the supercharged 5.0-liter V8 is one mean luxury sedan. With stock power ratings of 503 horsepower and 461 lb-ft of torque, this big Jag has no problem keeping up with some of the top performance coupes in the world, but for those XJR owners who want to shorten the list of cars that can be their Jaguar, tuners, like VIP Design, have the answer.

In working with the team at Viezu Technologies, VIP created the Jaguar XJ tuning package, adding substantially more horsepower and torque with a price of roughly $10,000 US dollars. The two companies showcased that package in the video above from the Viezu YouTube channel and the results are impressive.

VIP Design Jaguar XJ Tuning Package

In working with Viezu Technology, VIP Design pieced together a fairly simple 650 horsepower upgrade package for the 2009-and-newer Jaguar XJR with the supercharged 5.0-liter V8. This package adds a full exhaust system including high-flow catalytic convertors, a smaller supercharger pulley for more boost, a larger intercooler, freer-flowing air filters and an ECU tune.

Jaguar XJR Hood Up on Dyno

Based on the company’s data, this lifts the output of the supercharged V8 from 510 metric horsepower to 650 metric horsepower, or for those of you who prefer standard horsepower figures, we are looking at a jump from 503 to 641 horsepower. At the same time, torque figures climb from 627 nM to 824 nM, or in lb-ft, we are talking about an increase from 462 lb-ft to 608 lb-ft.

On the VIP Design website, this package has a list price of £7,995.00, which is a little over $10,000 US dollars based on the current conversion rate.

Dyno Action

In the video above, we watch as a Jaguar XJR long-wheelbase model makes a pair of dyno runs. In the first run, the car is stock, making 501 horsepower and 627 nM of torque. We don’t know for sure, but those seem to be standard horsepower numbers at the crankshaft, as a stock XJR most certainly doesn’t make 501 horsepower at the wheels.

Jaguar XJR Hood Down on Dyno

The second run shows the same car making another pull on the rollers with the VIP Design tuning package. On this run, the car is louder, but more importantly, it makes far more power. To be exact, this Jag lays down 643 horsepower and 824 nM of torque, so if that horsepower number is indeed standard, then this package actually offers a little more than 650 metric horsepower. For $10,000, that isn’t a bad deal for the big jump in power and sound.

"Before I was old enough to walk, my dad was taking me to various types of racing events, from local drag racing to the Daytona 500," says Patrick Rall, a lifetime automotive expert, diehard Dodge fan, and respected auto journalist for over 10 years. "He owned a repair shop and had a variety of performance cars when I was young, but by the time I was 16, he was ready to build me my first drag car – a 1983 Dodge Mirada that ran low 12s. I spent 10 years traveling around the country, racing with my dad by my side. While we live in different areas of the country, my dad still drag races at 80 years old in the car that he built when I was 16 while I race other vehicles, including my 2017 Dodge Challenger SRT Hellcat and my 1972 Dodge Demon 340.

"Although I went to college for accounting, my time in my dad’s shop growing up allowed me the knowledge to spend time working as a mechanic before getting my accounting degree, at which point I worked in the office of a dealership group. While I was working in the accounting world, I continued racing and taking pictures of cars at the track. Over time, I began showing off those pictures online and that led to my writing.

"Ten years ago, I left the accounting world to become a full-time automotive writer and I am living proof that if you love what you do, you will never “work” a day in your life," adds Rall, who has clocked in time as an auto mechanic, longtime drag racer and now automotive journalist who contributes to nearly a dozen popular auto websites dedicated to fellow enthusiasts.

"I love covering the automotive industry and everything involved with the job. I was fortunate to turn my love of the automotive world into a hobby that led to an exciting career, with my past of working as a mechanic and as an accountant in the automotive world provides me with a unique perspective of the industry.

"My experience drag racing for more than 20 years coupled with a newfound interest in road racing over the past decade allows me to push performance cars to their limit, while my role as a horse stable manager gives me vast experience towing and hauling with all of the newest trucks on the market today.

"Being based on Detroit," says Rall, "I never miss the North American International Auto Show, the Woodward Dream Cruise and Roadkill Nights, along with spending plenty of time raising hell on Detroit's Woodward Avenue with the best muscle car crowd in the world.
