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.

Yearly auto recall record demolished in 6 months

With nearly 40 million vehicles under repair campaigns and counting, 2014 will almost certainly go down as the year of the automotive recall. At just past the halfway mark, we are already at record levels, and there aren't any signs that the epidemic is slowing. General Motors' latest 8.4 million vehicle recall in the US puts the industry over the top for the title of the most cars with fixes pending from automakers ever. That's a prize no one ever wants to receive. According to TheDetroitBureau.com, the US recall total has hit 39.85-million vehicles to surpass the previous record of 33.01 million in 2004. Perhaps more surprising, with over 26 million repairs pending, it's still quite possibly that GM could recall more vehicles by the end of the year than the 27.96-million unit total of the entire US auto industry last year. With over 40 campaigns under its belt in 2014, the roughly one million cars it would take would hardly come as a surprise at this point, especially with increased government scrutiny into the Detroit automaker's processes. The pace of recalls started off relatively normal this year, with just a smattering of campaigns. The most surprising early on was Aston Martin calling in about 75 percent of its output since 2007 due to counterfeit plastic, but with just a few thousand cars, it was relatively tiny in pure numbers. GM really kicked things off soon after, but we didn't know it at the time. It issued its first bulletin for 778,000 Cobalt compacts in early February. Things only ballooned from there as more models were added to its growing ignition switch problem. The onslaught of announcements from every major automaker hasn't abated since then. Some industry executives are trying to put a positive spin on the situation. "With what's transpired (in recent months), there's a higher level of scrutiny," said Joe Hinrichs, Ford president of the Americas, to TheDetroitBureau.com. He believes that automakers are looking at data much more thoroughly than before, and it means better customer safety. Still, many consumers probably wish these problems had been found before their car went on sale.

Mercury rises around sexy Cougar pack

With a slightly larger body and a more luxurious interior, the Mercury Cougar doesn't carry quite as much cachet among pony car enthusiasts as the venerable Ford Mustang. But don't try to make that argument around Cougar super-fan Mike Brown. Since starting his Cougar collecting in 1988, Brown has become an absolute expert on the model, and he claims to have owned 400 of the Mercury pony cars in that time. Ten of them are in his collection today, not to mention a heap of spare parts in the garage. Check out some of the rarer members of Brown's fleet and allow him to tell you about them in this interesting interview from Electric Federal.
