Project Trail Force Jeep Wrangler goes to SEMA, then to a lucky winner

Extreme Terrain is an aftermarket parts company focused on the Jeep Wrangler. Partly just because it's a really cool thing to do, and probably having something to do with Jeep's upcoming 75th anniversary, Extreme Terrain found some dance partners to help work up a special 2015 Wrangler Rubicon that it will show off at the Bantam Jeep Heritage Festival in Butler, PA, then at SEMA in November, where it will be given away. Extreme worked with Barricade Off-Road and Kevin Tetz from the Spike show Trucks! to build the Wrangler it calls Project Trail Force. There is more than $24,000 worth of aftermarket gear on it, starting with the Ripp centrifugal supercharger that pumps an additional 140 horsepower into the 3.6-liter V6. It's got a 3.5-inch lift kit from Rock Krawler, Dana 44 axles strung between 37-inch BFG tires, Barricade bumpers, a 9,500-pound winch, fender flares, rock sliders, a 50-inch LED light bar above the windshield, LED spotlights on the A-pillars, and seven-inch KC Hilites headlights. Rugged Ridge worked over the inside with upgrades like all-terrain floor and cargo liners, plus seat covers, and a new navigation system with a back-up camera. If you want to win it, you can enter the contest at Extreme Terrain once every week until Oct. 23. The winner gets flown to SEMA to have Kevin Tetz hand the keys over. If you just want to see it, you can head to PA for that heritage festival. The Project Trail Force will also lead a Jeep parade that could set a Guinness World Record. The press release below has a lot more info on the build. Good luck.

NHTSA investigating power modules on Chrysler Group SUVs and minivans

The Center for Auto Safety is officially petitioning the National Highway Traffic Safety Administration to begin scrutinizing alleged problems with the totally integrated power module (TIPM) on about 24 Chrysler Group SUVs and minivans. The advocacy group claims that the part's failure can cause affected vehicles to stall or not start at all. NHTSA is still looking into the accusations and deciding whether a full investigation is actually warranted.
The CAS petition claims at least 70 TIPM failures, but according to NHTSA, six of the complaints are for models that don't have the modules. In 34 of the reported cases, the vehicles refused to start, and in 17 of them the engine stalled. There were also two allegations of smoke and one of a fire. However, none of these affected airbag deployment or resulted in a crash.
This petition isn't the first TIPM-related problem for Chrysler Group. A recent report in the New York Times alleged that it found 240 complaints potentially related to the issue on NHTSA's website alone. In September, the automaker also recalled 230,760 examples worldwide (188,723 in the US) of the 2011 Jeep Grand Cherokee and Dodge Durango replace the fuel pump relay circuit inside of the TIPM-7 with one external to the unit. The original part could allegedly cause the models to stall without warning. Even earlier, the company also recalled about 80,000 examples of the Jeep Wrangler and Dodge Nitro in 2007 to have the module reprogrammed.

Here's what it'll take to build a Jeep Grand Cherokee Hellcat

Let's get one thing straight: We want a 707-horsepower Grand Cherokee Hellcat to happen. Badly. The latest report from Motor Authority is encouraging; the bonkers SUV supposedly has a codename, Project K, and has been given the green light for production. Fingers crossed. You might be wondering why the Trackhawk isn't already a thing. Hellcat engines exist, SRT Grand Cherokees exist, so just combine the two, right? It's not quite that easy. Here, we outline what needs to happen, why it should be the quickest Hellcat vehicle out there, and why it won't come anywhere near 200 miles per hour. How To Build A Hellcat Jeep The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged V8. The first engineering problem is feeding the air-intensive beast that is the 6.2-liter supercharged Hellcat V8. Breathing is important on two counts: pulling in enough air for the combustion to put out 707 hp, and then cooling the various heat exchangers once the engine is up to temperature. Dodge did it with the Charger and Challenger, it can do it with the Jeep. This is one place where the Grand Cherokee's larger frontal area might be a boon, as it gives the engineers more surfaces through which to suck air. Once you generate the 707 horsepower and 650 pound-feet of torque, it has to get to the wheels somehow. Jeep's current SRT all-wheel-drive system will at least need some beefing up to handle the torque. It could require a more complete re-engineering. We at least know the ZF-supplied eight-speed auto, used in the Dodge Hellcat models, is up to the task. The Hellcat engine should fit in the Grand Cherokee, as it's about the same size as the 6.4-liter currently in SRT Jeeps, but the Hellcat is taller because of its supercharger. The hood may need to be raised or at least resculpted for clearance, as well as to address those cooling needs. Quicker Than Everything, But Not Faster 200 mph? We're skeptical, from both a physics standpoint and a legal one. A reminder of the quick/fast distinction: quick is acceleration, fast is road speed. The Jeep's all-wheel drive will help put the Hellcat engine's power to the ground in a more manageable way than the Charger and Challenger do through just the rear wheels. That means better acceleration times than the Dodges (11.0 seconds in the quarter-mile for the Charger Hellcat, 11.2 for its Challenger sibling).
