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-Chrysler shows its SEMA lineup

Fiat Chrysler Automobiles already previewed its 2014 SEMA show lineup with some slick renders. Now, the automaker has finally showed us the actual cars, and among the group there are definitely some that stand out more than others.
Dodge is really showing off its muscle at this year's show with four concepts that all pump up the power of the brand's models. Perhaps most interesting among them is the Challenger T/A Concept (pictured above) in striking Sublime Green and matte black. It's meant to resemble the classic Trans Am racer from the '70s. Under the hood is a 6.4-liter V8, and to fit the vintage style there's a pistol-grip gearshift inside.
The Charger R/T also gets some attention with the Mopar concept that shows off what FCA's aftermarket performance arm can do. Mods include an updated body kit, cold-air intake for the 5.7-liter V8 and a coil-over suspension kit. Beyond that, the Dart R/T Concept looks a lot meaner with a black hood with duct work that leads straight to the air intake. The rest of the compact sedan is dolled up in O-So-Orange paint and is fitted with upgrades to improve handling like a coil-over suspension and big brake kit from the Mopar catalog.

Roadkill builds crazy-cheap 1968 Dodge Charger rat rod using an old motorhome

Certain requests for description simply cannot be fulfilled, like if someone asked you to describe Picasso's Guernica or Gilliam's Brazil. There is only one appropriate answer to such entreaties, and that is: "You just gotta see it." That's where we are with the latest episode of Roadkill, wherein Messr's Freiburger and Finnegan dig out a 1968 Dodge Charger that Freiburger acquired in exchange for a set of cylinder heads, and intend to stuff it with the big-block motor from a long-bed, three-quarter ton Dodge pickup.
Only the pickup is too nice to tear apart, and the Charger needs a whole lot more lovin' - and parts - than initially expected. Enter, stage right, the Class A Dodge Pace Arrow motorhome with a 440 big-block purchased for $1,000, and a retired Plymouth Fury from a previous episode.
What ensues over the course of the 40-minute installment is more cuttin', yankin', leakin', stallin', hammerin' and smokin' action than you've seen in a long time, and some techniques that would have made even Cooter wonder, "I'm not sure if we should do that." By the end, though, the payoff is good enough to make you think about perusing AutoTrader for a '68 Charger just to see if maybe...
