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:

1970 Hemi Challenger is a family heirloom with serious muscle

Petrolicious turns up the emotion in its latest video about a family's connection to their 1970 Dodge Challenger. The orange muscle car that gets the spotlight here is a remarkably beautiful vehicle, but the story of a father and his sons at the core of this clip might leave you feeling a little misty eyed. Juan Escalante is the current owner of this Challenger, but it belonged to his dad first. Juan's father spotted the iconic muscle car during the 1969 Detroit Auto Show and had to have one. He soon placed an order for the orange '70 Challenger R/T with the rare combination for that year of a 426 Hemi V8 and a four-speed manual gearbox. The family even brought the coupe with them when they moved to Venezuela in 1972, and local fans dubbed it El Hemi. However, parts were scarce for the muscle car in that country, and it returned to the US in 1996 for a restoration. Now, the rumbling Challenger with its Coke-bottle profile and black hood is the world's most awesome family heirloom for the Escalantes. In this poignant video, Petrolicious shows how the coupe connects Juan to his father. Related Video:

Values snowball for legendary Tucker Sno-Cats, latest toys of the super rich

Here's a fun-sounding vehicle perfect for the cold and snow that's currently gripping much of North America. Tucker — no, not that Tucker — just marked its 75th anniversary making the Sno-Cat, its orange-painted, four-tread snow vehicles that have inspired backcountry skiers, collectors — and increasingly, the super rich. Bloomberg in a recent story writes that demand for the Medford, Ore.-based company's products is soaring on demand from the wealthy, who need a way to get to their backcountry mountain retreats. They're also in demand from collectors and gearheads who also love snow, like two anonymous collectors who are believed to have amassed more than 200 vintage Sno-Cats. The value of vintage models has reportedly tripled in the past five years to well over $100,000 for a fully restored rig. Tucker Sno-Cat Corp. claims to be the world's oldest surviving snow vehicle manufacturer, launched by E.M. Tucker in 1942 out of a desire to design a vehicle for traveling over the kind of deep, soft snow found in the Rogue River Valley of his childhood. It was four Tucker Sno-Cat machines that helped English explorer Vivian Fuchs and his 12-man party make the first 2,158-mile overland crossing of Antarctica in 1957-58. While many of the company's competitors either shuttered or adapted to serving ski resorts with wider, heavier treads, Tucker has stuck to its formula of making lightweight vehicles to travel over deep snow. Many Tuckers use Chrysler's flat six-cylinder engine, or its Dodge Hemi V8 for larger Sno-Cats, mounted rear or centrally, with basic, no-frills aluminum cabins. Sno-Cats all have four articulating tracks that are independently sprung, powered and pivoted at the drive axle. Track options come in three different types: conventional steel grouser belt track, rubber-coated aluminum grouser belt track, and one-piece all-rubber track. Steering is hydraulically controlled by pivoting the front and rear axles for smooth movement over undulating terrain with minimal disturbance of the ground cover. The company today makes 75 to 100 Sno-Cats a year for customers including the U.S. military, oil-drilling crews in cold places like Alaska and North Dakota, and utilities. But demand is so high that it's launched a profitable service reselling and refurbishing old machines. E.M. Tucker's grandson, Jeff McNeil, now head of this division, scours Google Earth for abandoned Sno-Cats rusting in backyards that he might be able to acquire and fix up.
