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.

2016 Jeep Wrangler recalled over impact sensor wiring

Fiat Chrysler just announced a pair of recalls totaling nearly 311,000 units. The bigger recall affects certain 2016 and 2017 model year Jeep Wranglers. Although, since FCA claims all of the affected 2017s are in the company's hands, really, only 2016 owners should pay attention here. The affected Wranglers suffer from an issue where wiring disconnects from impact sensors in certain types of crashes, potentially preventing the airbags and pretensioners from activating. FCA uncovered the problem in what its press release calls "a routine, in-house crash test" and claims "service availability is imminent." The affected Jeeps require a simple rewiring. The other recall, announced Tuesday, is more of a fleet issue, affecting 2007 to 2013 model-year Ram 2500 and 3500 pickups and 3500, 4500, and 5500 chassis cabs and 2011 to 2014 Dodge Charger Pursuit police vehicles. There's a problem with "premature diode wear" in alternators that are subject to "frequent load cycling, at or near maximum amperage, [or] in hot ambient temperatures." Affected alternators could short out, causing a vehicle to stall or potentially catch fire. FCA lists 182,743 affected Wranglers in the US, 18,011 in Canada, 3,087 in Mexico, and 20,948 in global markets. The Ram/ Charger Pursuit recall lists 74,833 vehicles in the US, 10,077 in Canada, 1,088 in Mexico, and 134 outside the NAFTA region. Of all those vehicles, the Jeep recall hasn't caused any injuries or fatalities, while FCA says it's aware of one "potentially related injury" and no accidents due to its fleet vehicle recall. FCA says it will notify owners/operators of affected vehicles when service appointments are available. As per usual, all the work is free of charge. Related Video:
