 10 Day Jeepspeed Xj Cherokee Build Jeep Cherokee Overall

Two issues ago, we began coverage of a unique buildup that posed a question of great interest: Could JeepSpeed racer Jason LaFortune and his crew at Temper-Mental Racing turn a tired, 140,000-mile ex-Forest Service Cherokee into a race-worthy XJ in just 10 days? LaFortune had done a similar short-fuse build previously, but that two-week timeframe seemed almost leisurely by comparison to this exercise.

To get the job done, LaFortune figured he and his team would have to work night and day-literally. So the core group of guys you've seen over the past couple issues would each day be augmented, or sometimes replaced, by a fresh group of builders and fabricators once the sun went down. By LaFortune's own admission, the pace of work changed dramatically between night and day, as more guys clustered around the Jeep tended to make things a little more chaotic. Our curiosity piqued, and we let Day 6 turn into Night 6 before we showed up at the Temper-Mental garage.

 10 Day Jeepspeed Xj Cherokee Build Jeep Roll Cage

In our last issue, we pointed out that the Jeep's rollcage was complex enough-and important enough to the racer's safety-that it would require nearly the entire 10-day build time to complete. On Day 6, the crew finished X-bracing the main hoop and also added the horizontal bar to mount the DJ Safety harnesses. Jon Krellwitz is fitting a side bar that will run alongside the driver's seat. Note that the Beard racing seat, still in its protective plastic wrap, is set (but not anchored) in place to help Krellwitz locate the side bar.

 10 Day Jeepspeed Xj Cherokee Build Gauge Placement

One big difference between the night and day crews: there are a lot more guys around at night. Matt McCallum holds an Auto Meter gauge box in the cab while Jason Bernal, Patrick Smith, and Krellwitz debate its placement. Discussions like this could get lively, but never heated. Despite everyone showing signs of fatigue at this point, tempers never flare. These guys would never make it on one of those wrench-throwing, obscenity-yelling TV shows.

 10 Day Jeepspeed Xj Cherokee Build Three Row Radiator

No fancy aluminum race radiator here, just a "standard three-core replacement radiator, the kind you can buy for $100 all day every day," LaFortune said. "That's what's so great about JeepSpeed racing. Using a stock motor, transmission, brakes, and other parts keeps the costs low. You can get into this series for about $10,000." Of course, to be truly competitive costs more. Also note the frame reinforcements.

 10 Day Jeepspeed Xj Cherokee Build Stock 2Wd Axle

Nighttime is great for catching sparks in flight. Here, LaFortune cuts the stock shock mounts off of the 2WD front axle he'll use for short races. Eventually, new shock mounts will be welded on.

 10 Day Jeepspeed Xj Cherokee Build Jeep Build Night Crew

When we left the garage at about 11 p.m., the crew still had hours to go before calling it quits for the night.

 10 Day Jeepspeed Xj Cherokee Build Air Intake Filter

Prior commitments kept us away from the garage during Day 7, which LaFortune called the team's "most productive day." We tried not to have hurt feelings. Among the tasks done on Day 7 was the installation of the Unique Metal Products (UMP) in-cab engine air cleaner.
