A cool boost to turbocharger performance

Since the advent of the forced-induction engine, we have been looking for ways to get every drop of performance we can. There are many approaches to getting additional power using better intercooling, water injection, or even adding nitrous oxide. One take on a short instant burst of power is being researched by Mahle and involves providing supercooled air to an engine, which allows it to burn a leaner fuel mixture and produce more power. The supercooling idea is not new and was examined by Ford in 1993 on the Mustang Mach III concept car, then brought up again in 2003 with the SVT F-150 Lightning concept. Ford called its system the SuperCooler; it was designed to work with any turbocharged or supercharged engine equipped with a water-to-air intercooler. The system on the Lightning concept used a small tank of antifreeze that was hooked up to the truck air conditioning compressor. The air conditioning compressor cooled the antifreeze down to about 30 degrees. The other side of the tank was hooked up to the air-to-water intercooler, which usually had a temperature over 100 degrees. Once the antifreeze was circulated from the tank into the intercooler, it would lower the intercooler temperature and provide for a cooler, denser air charge into the engine; the result was around 50 extra horsepower for a burst of about 30 seconds to a minute, depending on the size of the tank. The system for the Lightning was to be offered as a $750 option and would have been targeted towards drag racers and the like, as it could be used for a run down the drag strip and then re-cooled by the time the truck was back in line. The system was fairly non-intrusive – it only weighed about 25 pounds and did not require a new compressor or intercooler. But as with many concepts, it was ultimately scrapped. The technology was always stuck in the back of my mind, but with larger and more powerful engines being produced it could not find its place. With the advent of new fuel economy standards, we have seen small-displacement turbocharged engines pop up and they seem like the perfect candidate for this type of technology. Ford's EcoBoost 1.0-liter three-cylinder turbocharged engine, as used in the Fiesta and Focus, is one such candidate for this technology. It would add a negligent amount of weight but could provide a boost of 10 to 20 horsepower when needed, like merging onto the highway or catching up to traffic.

Ford announces fix for 2021 Expedition and Lincoln Navigator fires

In the middle of May, Ford announced a recall of around 39,000 Ford Expeditions and Lincoln Navigators from the 2021 model year due to fires starting under the hoods of the SUVs. At the time, Ford had received 16 incident reports, 14 of them happening with rental vehicles. The automaker cautioned owners to park their vehicles outside and away from structures while engineers figured out what was happening and how to fix the problem. Since that May announcement, five more fires have been reported, four of them rental vehicles, and there's been one burn injury. The company announced it understands the problem and has a fix, at the same time widening the scope of potentially affected vehicles. Instead of recalling 39,013 units built between December 1, 2020, and April 30, 2021, the recall now includes 66,221 vehicles assembled from July 27, 2020, to Aug. 31, 2021. The suspected culprit is a circuit board provided by a supplier that changed manufacturing location during the pandemic. Ford's press release on the matter stated that "circuit boards produced at this facility are uniquely susceptible to a high-current short." The affected vehicles are fitted with either an 800-watt or 700-watt cooling fan system. About a third of the recalled population are fitted with the former, and should get a quick fix at the dealer. On these SUVs, techs will inspect the battery junction box. If they find evidence of melting, they'll replace the whole box. If not, they'll simply remove the engine fan ground wire that runs to the battery junction box; since this ground relay is redundant, the change doesn't alter operation of the fans.  Owners with the 700-watt system might need to wait until September for a fix. These vehicles need an auxiliary relay box with a wire jumper, but the parts aren't available now.   Ford's notifying all owners via the FordPass app, and will follow up with owners of the 700-watt cooling system once the parts are in stock. Until their vehicles are fixed, Ford says the SUVs are safe to drive but that they should still be parked outside and away from structures. The somewhat mixed messaging — 'Yes, your cars are safe to drive, but they could catch fire so don't park them near anything flammable' — encouraged a group of owners to file suit against Ford. Owners with questions can contact Ford customer service at 866-436-7332 and reference recall No. 22S36.

Ken Block hoons his Ford F-150 RaptorTrax on the slopes

Ken Block drives Fords. Hoons the heck out of 'em, actually. Mostly Fiestas, but also the occasional Focus or Mustang. But earlier this year, the Gymkhana guru revealed his baddest Ford yet: an F-150 SVT Raptor on tracks. And true to form, here he is putting it to the test in the latest video from Monster Energy and Hoonigan Racing.
Filmed at Baldface Lodge in Nelson, BC, the video pairs Block up with snowboarders Zak Hale and Ethan Deiss for some deep-powder action. You'll want to watch the video for yourself, but the bottom line is that the RaptorTrax beats the heck out of waiting on line for the ski lift. It's enough to make us start to look forward to winter... almost.
