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: 1987 Dodge Ram 50 with V8 swap

Chrysler did very well selling Mitsubishi Forte pickups with Plymouth and Dodge badging in the United States, even after Mitsubishi began moving the same trucks out of their own American dealerships in 1982. The 1987 Ram 50 2WD short bed weighed in at just over 2,500 pounds, so it was reasonably perky with its 2.0-liter G63B four-banger making 90 horsepower… but there's no replacement for displacement! At some point along the line, a Chrysler small-block V8 engine found its way into the engine compartment of this truck, now residing in a car graveyard in Sparks, Nevada. This was the cheapest new Dodge-branded pickup Americans could buy as a 1987 model, though it had to compete with its near-identical Mitsubishi Mighty Max twin for sales. The 1980s were great times for little pickups in the United States, but a desire for bigger cabs and more creature comforts doomed them by the dawn of the following decade. The most interesting thing about this engine swap is that it didn't involve a Chevrolet or Ford small-block V8. Both the Chevy small-block and Ford Windsor V8s are a few inches narrower than the Chrysler LA-series V8, which makes them easier to stuff into a small vehicle. It appears that engine length was the critical dimension in this case, since the Mopar seems to have had enough side-to-side clearance to avoid any slicing of Mitsubishi steel to make it fit. My guess is that whoever did the swap happened to have the engine handy and that's why it's here. Keeping it all Dodge might have been a factor in the decision as well, though the truck's Mitsubishi ancestry makes that unlikely. It was over 100°F out when I found this truck, so I wasn't motivated to check block casting numbers to determine exactly which LA engine we're dealing with here. The easiest LAs to get cheap for the last four or so decades have been the 318 (5.1-liter) and the 360 (5.8-liter), so one of those two is the most likely candidate here. Power levels for these engines got pretty dismal during the Malaise Era, but anyone with the wrenching skills to do this swap would have applied some basic power-enhancing wizardry before the engine went in. We can see there's an Edelbrock Performer intake manifold, and you might as well stab in a better camshaft if you're upgrading the intake. How much power? With a four-barrel carburetor on a dual-plane intake plus a meaner cam, 300 to 350 horsepower is easily achieved with one of these engines, even with stock exhaust manifolds.

FCA plants skipping summer shutdown to keep up with demand

Hopefully, some FCA US factory employees don't have big plans for the usual summer shutdown, because the automaker is keeping several plants running this year. Demand is so high that the company wants to keep models rolling off the assembly lines. Four FCA US assembly plants, all the engine factories, and some locations that build transmissions are staying open throughout the summer, according to the Detroit Free Press. Usually, these sites would see a two-week shutdown for the company to retool and perform repairs. This year, factories are staying open for FCA to support its strong sales. The lines that remaining humming through the summer show an inclination toward the automaker's popular SUV's and crossovers. They include the Jefferson North Assembly Plant in Michigan that builds the Jeep Grand Cherokee and Dodge Durango; Saltillo Van Assembly in Mexico that constructs the Ram ProMaster; Toledo Assembly Complex in Ohio that produces the Cherokee and Wrangler; and Toluca Assembly in Mexico that makes the Dodge Journey and Fiat 500.
