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:

Junkyard Gem: 1994 Dodge Caravan with manual transmission

The K Platform saved Chrysler from certain doom after the company's 1979 bailout by the federal government, and one of the most successful K-based vehicles was the one that spawned the American minivan craze in 1984: the original Dodge Caravan/Plymouth Voyager. Built all the way through the 1995 model year, these K-Caravans or K-Voyagers could be purchased with a four- or five-speed manual transmission, but just a handful were sold that way. Here's an extraordinarily rare late 5-speed example, spotted in a San Francisco Bay Area wrecking yard. The shifter location is a little awkward, requiring the driver to reach back a bit more than would be the case in, say, a Dodge Shadow (which shared the same powertrain). It's too bad that Chrysler never offered these vans with five-on-the-tree manuals. Even though plenty of Mitsubishi-V6-powered front-wheel-drive Chryslers of the late 1980s and early 1990s were available with manual transmissions (e.g., the Chrysler Laser/Dodge Daytona or the Plymouth Sundance/Dodge Shadow), Chrysler minivan shoppers who wanted a stickshift had to take the four-cylinder engine (either a Chrysler 2.2/2.5 or, in the early years, a Mitsubishi 2.6 Astron). This one has the naturally-aspirated 2.5-liter engine that went into so many Plymouth Acclaims and Chrysler LeBarons. In 1995, it was rated at 100 horsepower, which made for stately acceleration with a full load of passengers. For the 1989 and 1990 model years, a 150-horse turbocharged Chrysler 2.5 with 5-speed was the high-performance minivan setup... and you should let us know if you find a factory-built one. This is only the second example of a manual-trans-equipped 1990s Chrysler minivan I have found in the junkyard (the first was this '93 Voyager), and both vans were lightly-optioned El Cheapo models with cloth seats and hand-crank windows; the manual transmission was a bit cheaper than the automatic in those days. At least this one has air conditioning. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

Plymouth Rapid Transit System muscle car concepts going to auction

Over the past decade, Chrysler has built a reputation for amazing custom concept cars based on production vehicles for the SEMA Show and the Easter Jeep Safari. But the company's customization tradition has much deeper roots that include this collection of muscle car concepts headed for Mecum's Indianapolis auction this May. The collection includes three Plymouths that were featured in the traveling display called the Plymouth Rapid Transit System, and a Dodge that appeared at the 1969 Chicago Auto Show. The possible crown jewel of these cars is the 1971 Plymouth Road Runner, and that's simply because the car is completely unrestored with just 1,300 miles on the odometer. Apparently the owner of the shop that built the car for Chrysler got it back after the Rapid Transit System tour ended and took care of it until he later sold it to the late Steven Juliano, whose estate is now selling this collection of cars. Like all of these cars, modifications were mainly visual, but they were extensive. A custom nose and headlight lenses were fitted that added six inches of length, according to Mecum. The car's bumpers were removed completely, as were the external door handles. Recessed hood scoops were added to the hood, and the trunk lid was lowered by four inches to create a rear wing. The taillights were given red, yellow and green lenses like traffic lights. But the best additions were molded Road Runner head marker lights. The interior is mostly unchanged, and the engine is a stock 383-cubic-inch V8 with an automatic transmission. It also has power steering and brakes and the Plymouth Road Runner horn, which makes a "Beep! Beep!" sound like the cartoon the car is named after. 1970 Plymouth Duster View 12 Photos Then there's the 1970 Plymouth Duster in the collection with arguably the best paint scheme. It's bright green with groovy "DUSTER" lettering on the hood and various contrasting panels. It's actually the second scheme the car used, as according to Mecum, the car was built for the 1970 tour and then redesigned for the 1971 tour. The paint is matched with color-coordinated wheels and blue and green floral pattern floor mats. There are unique body changes, too, such as the custom headlight housings, functional brake air ducts up front, fake extractor vents above the rear window, racing-style fuel cap and rectangular exhaust. Mechanically, it has a stock 275-horsepower 340-cubic inch V8 and four-speed manual transmission.
