Ford EcoBoost V6 hits the dyno before hitting the track

Ford Racing just unveiled the Riley Daytona Prototype that will make its racing in the United SportsCar Racing Championship Rolex 24 at Daytona in January, and now it has released a video showing development of twin-turbo 3.5-liter EcoBoost V6 that powers the car. Using the same block and heads that can be found on a production Ford Taurus SHO, this new racecar benefits from the collaboration between Ford Racing and Ford powertrain engineers.
While we still don't know what kind of power this engine is putting out, it has definitely gotten a workout at Ford's 17G dyno. This area deep within Ford allows the automaker's racing program to work hand-in-hand with production engine programs, which can be a benefit to racing operations and production cars alike. Scroll down to hear a few people from Ford talk about the crosspollination between its racing and engine teams and watch the EcoBoost get red hot on the dyno.

Top torque-to-weight ratios under $100k, $50k and $25k

Horsepower may steal a lot of headlines, but the always-more-complex torque figure is often a critical one for both the workingman and the motoring playboy. The measure of rotational force represents the twist that can liquefy one's tires or haul one's horse trailer. Good stuff.
It follows then, that as with the horsepower-to-weight list that we assembled for you a few months ago, a list of cars that offer the most pound-feet with the fewest pounds to carry, is an interesting one to break down. Sure, there's a big difference in how the torque is applied from a turbocharged six-cylinder in a Swedish luxury sedan and a massive heavy-duty truck's turbo-diesel. But being the car/stat geeks that we are, we think it's kinda neat that those two vehicles rank near each other where torque and weight intersect.
As with the horsepower list, we've given you figures as pounds per every one pound-foot. Again broken down into broad price categories, we've got a mixed bag of 2014 and 2015 models here, too. Every effort has been made to select the most up-to-date prices and specs, and we've also to omitted some '14 cars that won't be re-upped after the ongoing yearly changeover.

2015 Mustang-based Saleen S302 to boast as much as 640 hp

The Ford Mustang is obviously a famous performance vehicle in its own right, but it often works even better as a platform for the aftermarket to upgrade. With the all-new 2015 model just now hitting the scene, the famous tuners at Saleen are getting their improvements for the new pony car ready for the world. After recently teasing it, the specs for its fresh S302 model are officially here, along with a first look at it in profile.
Of course, the biggest question on everyone's mind is how much power the company can get from the Mustang's V8. With the 2015 V8 model rated at 435 horsepower and 400 pound-feet, Saleen expects to bump the Ford factory numbers slightly to 450 hp and 410 lb-ft in naturally aspirated form, or with the benefit of a supercharger, it will rocket the engine's output figures to 640 hp and 565 lb-ft. No matter which powerplant a buyer chooses, there are a wide variety of available final-drive ratios with a six-speed manual or automatic gearbox.
Available as either a coupe or convertible forms, Saleen will offer its S302 in three trim levels - White Label, Yellow Label and Black Label. The White Label is the only naturally aspirated one of the bunch, but it still benefits from upgrades like a new exhaust, limited-slip differential, improved suspension, heat extractor hood and rear wing.
