eBay Find Of The Day: 1988 Saleen Ford Mustang General Tire 21R race car

Saleen may be making headlines these days for working on the Tesla Model S, but its history and bread-and-butter is all about the Ford Mustang. The rear-wheel-drive Dearborn pony cars singlehandedly put the company on the map in the '80s. Founder Steve Saleen was already a talented American racing driver when he started the venture, and like many auto industry businesses before him, Saleen went to the track to prove his vehicles' worth. Now, there's a chance to buy one of those early racers on eBay Motors.
Saleen Mustangs raced in the Sports Car Club of America Escort Endurance Championship - a series of multi-hour races meant to challenge man and machine. Ostensibly a showroom stock class, the cars had larger wheels, tuned suspensions and other upgrades that stretched the concept slightly. Saleen found major success though, taking the championship for its class in 1987 and winning the 24 Hours of Mosport consecutively from 1986 through 1988.
According to the seller, Saleen only built eight of these cars, and this one carries the #21R serial number. They all started life as new Mustangs from Ford dealers but were immediately stripped and prepped to go racing. Beyond obvious mods like a roll cage, they featured eight-inch wide wheels in front, an inch of additional track width, stiffer suspension bushings and much more.

Ring Brothers shows 1965-66 Mustang fastback carbon fiber body

We covered one of Ring Brothers' more extreme SEMA builds yesterday, the De Tomaso Pantera-based ADRNLN, but if that well-executed but over-the-top Italian-American exotic is too much for you, then perhaps this Ring Brothers 1965 Ford Mustang fastback with a carbon-fiber body suits your tastes better.
What the performance-parts manufacturer is showcasing with the Mustang is the carbon-fiber body itself, which is fashioned around the 1965-66 fastback. It can be bought from the company and bonded to the skin and unibody as a do-it-yourself project, or you can take your Mustang to Ring Brothers and have the body installed there. The fenders, doors and quarter panels are two-inches wider than stock, and Ring Brothers offers a custom widebody chassis to those who want the complete package.
The show car looks sharp in person lowered on HRE wheels, and we appreciate the bare front end so we can see the supercharged V8 and front coilover suspension, though the details on those performance upgrades are slim. Also note the custom independent rear suspension setup at the rear.

Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.
