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.

Will the Ford GT make 630 hp?

Ford intends to build just 250 examples of the next-generation GT annually when production begins next year. That's low even by supercar standards, but anyone with an Xbox One can drive the highly anticipated model right now in the demo for Forza Motorsport 6. The car is even on the cover of the retail version, but the game might be giving a glimpse at one of the upcoming vehicle's biggest secrets. According to the specs page, the GT makes 630 horsepower and 539 pound-feet of torque, according to Motor Authority. Weight is shown at 2,890 pounds with a front/rear distribution of 43/57. Until now, Ford's only comment on the GT's output from its 3.5-liter twin-turbo V6 is "more than 600 horsepower," and that's certainly the case here. If accurate, the figures make the new model 130-hp more powerful than than the last GT, while also being hundreds of pounds lighter. Compared to modern competitors, the GT would be less powerful than a Ferrari 488 GTB and heavier than a McLaren 675LT. Unfortunately, Ford isn't commenting on the numbers in the game. "As we stated back at NAIAS, the Ford GT will produce more than 600 horsepower, and we can't speak to what Forza includes as specifications in their video game," company spokesperson Matt Leaver said to Autoblog via email. Don't think this is all doom and gloom, just yet. For one thing, more than numbers make a great car. Plus, the GT is still quite some way out from production, and spy shots still show it under development. Even if these figures are accurate at the time of Forza's development, that doesn't mean that they can't change in the meantime. Related Video:

Lewis Hamilton owns 15 cars, uses tow trucks to keep the mileage low

No matter how you feel about Lewis Hamilton off the track, it's impossible not to respect his talent behind the wheel. Currently, Hamilton is the second most successful Formula One driver of all time. His 67 wins and four championships place him only behind Michael Schumacher's 91 wins and seven championships. With all those winnings, Hamilton has racked up a decent personal fortune, much of which he uses to buy cars. Except he doesn't drive them quite as much as you might think. According to The Sunday Times, Hamilton's net worth of just over $207 million makes him one of the richest sports figures in the UK, just behind David Beckham. In a recent interview with the British newspaper, Hamilton gave some details on his personal car collection. His first car was a used Mini Cooper, soon followed by a Mercedes-Benz C200. Both have long since been replaced by a pair of original Shelby Cobras, a 1967 Shelby GT500, a Ferrari 599 SA Aperta, two LaFerraris (a red coupe and a white Aperta), a McLaren P1 and a Pagani Zonda 760 equipped with a manual transmission. All in, Hamilton has about 15 cars split between homes in Monaco and Los Angeles. Unsurprisingly, he has a Mercedes-AMG Project One ( a car that shares more than a little with his F1 W09 EQ Power+ race car) on the way. Hamilton has some hot takes on his personal collection. "The Zonda is terrible to drive," he said. "It's the best-sounding car I own, but handling-wise it's the worst. I got it in manual because I didn't like the tiptronic version. The tiptronic Pagani offered was worse than the Smart Roadster I had." He also says his Shelby Mustang is a "beautiful car, but a heap of junk." In order to keep the miles down (and valuations up), Hamilton apparently has a tow truck on retainer in Los Angeles. When he's finished driving one of his Ferraris, he'll have the car towed back to his place. Classic cars are becoming a solid and serious investment, and Hamilton doesn't want to squander his wealth like some other athletes. That said, there are a couple more cars Hamilton would love to own, including a Mercedes-Benz 300 SL (the one with the gullwing doors) and a Ferrari 250GT California Spyder (the one from "Ferris Bueller's Day Off").
