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:

Fiat brand chief reassigned then resigns amid flagging sales

Jason Stoicevich was replaced as head of the Fiat brand in North America just the other day. He was immediately reassigned to another job within Fiat Chrysler Automobiles. But according to Automotive News, Stoicevich quit the new job – and the company altogether – the very next day. The development comes amidst flagging sales for the Fiat brand in America. The introduction of the awkward-looking 500L multi-purpose vehicle has been largely regarded as a sales disaster in the US. Despite having just introduced the new 500X into the growing crossover market, and an overall upward trend across FCA group sales, the Fiat brand's figures have been dropping all year. While the Italian brand's volume has fluctuated from month to month compared to last year's sales, the number of cars its dealers sells on an average day has been firmly in decline. Fiat's downward trend reflects a general tendency in the market towards larger vehicles at the expense of smaller ones. However, the powers that be in Auburn Hills evidently felt that a change of leadership was in order, so it placed Dodge chief Tim Kuniskis in charge of all the company's mass-market passenger-car brands – namely Dodge, Chrysler, and Fiat – and moved Stoicevich to running the group's fleet and small-business operations. Stoicevich remained in charge of the company's California Business Center, but it seems as though he was as dissatisfied with the switch as his superiors were with the performance of the brand over which he presided, and so he apparently elected to step down and leave the company.

Mopar Hellephant is sold out, but here are 4 other awesome crate V8s to try

Despite a relatively enormous $30,000 price tag, Mopar's 1,000-horsepower supercharged Hellephant crate engine sold out in just 48 hours. Some enthusiasts may have missed out on the crazy engine due to lack of funds, or they just assumed there would still be some Hellephants down the line. But worry not, swap-happy gearheads. There are plenty of V8s in the world to pick from, and we highlighted four favorites. They're not as powerful, but they're all cheaper, and still have a lot to offer. Mopar 6.2L Hellcrate Odds are a lot of prospective Hellephant buyers were Mopar fans to begin with, so we'll start the list with the next-most-potent offering: the Hellcrate. This is the same supercharged 6.2-liter V8 found under the hood of the Dodge Charger and Challenger Hellcats and the Grand Cherokee Trackhawk. It makes 707 horsepower and 650 pound-feet of torque like those cars, too. It's also about $10,000 cheaper than the Hellephant engine at $20,020, and that leftover money can be used to finish the project or for aftermarket upgrades to get it closer to the Hellephant's output. GM LS9 6.2L The Hellcrate isn't the only factory supercharged crate engine on the market. From General Motors comes the supercharged 6.2-liter LS9 V8. This is the engine that was used in the C6 Corvette ZR1. At 638 horsepower and 604 pound-feet of torque, it doesn't make as much power or torque as the Hellcrate. But it does boast a dry sump oil system. So instead of pumping oil out of a pan at the bottom, the engine uses an oil tank mounted remotely that pumps oil into the engine. This means the engine is shorter overall, and can be mounted lower for a better center of gravity. It also means that there's almost no risk of running the engine dry in hard cornering, as could happen with a normal oil sump where the oil can slosh to the side without the oil pump. Basically, it offers some major benefits if you want supercharged V8 power for a road course car. It's also a tad cheaper than the Hellcrate at $18,149. But get one while you can, because GM is only selling what's left from when it was building the C6 ZR1. Ford Aluminator 5.2XS Our pick from the Blue Oval lacks a supercharger, but it's still pretty sweet.
