Dodge Demon's A/C helps its supercharged Hemi make more power

Staying cool is one important key to performance. Simply, more air means more power, and cool, dense air is better than hot air. While forced induction might help make copious amounts of horsepower, turbos and superchargers produce heat. Intercoolers help, but the new Dodge Demon and its supercharged Hemi need a bit of an extra boost. In Drag Mode, the Demon's engine commandeers the car's air conditioning system to help chill things out. The Demon will have the first production application of a liquid-to-air charge air cooler chiller system. Literally, the car's air conditioning system is used to cool the air going into the engine, dropping temps by up to 45 degrees Fahrenheit. Dodge claims the system helps achieve "temperatures previously unattainable by pressure-charged street-legal production vehicles." As cool as this may sound, the technology isn't new. Ford had a prototype system in the early 2000s called SuperCooler, though that system never made it to production. While the Demon's system doesn't have a super cool name like the one from Ford, the pair essentially work in the same way. In theory, it should have the same effect as a bottle of nitrous. According to Autoweek, Ford's system bumped up the output of the F-150 Lightning by about 50 horsepower. Turns out that air conditioning isn't always a huge power suck. Related Video:

Bull leads Texas police on four hour chase

A bull leading police on a chase through a Texas town may sound like something out of a country music song, but police in Arlington, Texas recently had just such a situation on their hands. According to WFAA, on the afternoon of May 9, a young bull got loose from his pen and decided to take a stroll through the streets of Arlington. "There was a cow walking down the neighborhood," said Arlington resident Jillyan Nance. "It trotted down my home and cut across our yard into the neighbor's yard." Arlington police were alerted to the escaped bull and, in a scene more Texas than Steve Earle drinking a Shiner at the Alamo, they attempted to chase it down with police cruisers. For the next four hours, police engaged the creature in a sedate, low-speed chase through Arlington, Dalworthington Gardens, and other neighboring towns. The bull, for his part, largely ignored his pursuers and the throngs of people coming out of their houses to watch the strange scene and post pictures to Facebook and Instagram. With numerous police cruisers in not-quite-hot pursuit, the bull ambled along the shady streets, stopping here and there to munch on some grass and take in the views. Eventually, a friendly local rancher showed up and lassoed the bull in Dalworthington Gardens just before 9:00 p.m. Police have not released the name of the bull's owner or any motive for its escape. Perhaps, like the unicorn that escaped into a California orchard back in February, it decided that it had had enough of working for a living and was looking for something else.

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.
