"Check out the traction control." Pete Mungo dropped the Richmond fromThird to Second and pitched the car sideways through the rain and themuck until a light on the dash blinked on and brought the AMX back intoline. "I have ABS too." Pete stomped open the throttle and sent staffand equipment sliding before a stab of the brakes heaved us against theshoulder restraints. A quick flip of a disguised switch and the soft humfrom the muffler became a roar as an electronic gate redirected the flowto a set of massive 31/2-inch tubes. Under the hood, a series ofelectric eyes and sensors monitored the engine and chassis needs as werolled through the rural backwash of Norwalk, Ohio, in Mungo's '69 AMX,which was to become the winning car of the '05 Real Street Eliminator.
So what makes a guy bring the extra-expensive fruit of his labor andflog it through a rainstorm and manure-soaked backroads of an Ohiocornfield? Magazine glory. The same glory that has drawn RSE competitorssince 1985 to pit their building pregame and mechanical agility to thetest against all comers. This year, the readers voted on CarCraft.comfor their favorite six and we took them to the Norwalk raceway forquarter-mile and braking then North along Lake Erie to Marblehead pointfor a thorough evaluation of the street manners and overall buildquality of the contestants' rides.
This year, each car was evaluated based on quarter-mile elapsed time,braking distance, engineering, craftsmanship, and ride-and-drive. Beforewe did a thing, we staged an open-hood car show to judge the beauty,style, and stance of each car. On the road to Marblehead, we stopped sixtimes so each staffer could ride with each contestant to evaluate noise,vibration, and harshness and find out where the corners had been cut inthe name of performance. Even though the autocross was rained-out, westill were as tough as we could be during the test. Think it was easy?Read on.

Mungo's car stood out right away with Corvette wheels and an aluminumsmall-block (yup, the "C" word). He has owned the car since graduatingfrom high school and has tweaked it for years, and it shows. Since theAMX is getting relatively rare, most of the parts on the car arehandmade, proof of his skills as a shop owner and mechanical tradesman.The body was painted in his backyard, and the car features late-modeltricks like ABS, traction control, fuel injection, and air/fuel datalogging, which were all hand-adapted by the owner.
"It's like watching a fighter jet land on an aircraftcarrier."
-An observer of Mungo's AMX braking
The aluminum look is actually glass-beaded steel. The interior wasloaded with tricky stuff
And it's flat-out fast. Pete clicked off a 10.64 at 132 mph to be secondfastest in the quarter-mile. He then turned around and flattened thebraking test with an impossible 101-foot stop. Remember this car wasbuilt in 1969. On the street, the computer-controlled systems took allof the fun out of 500 hp on a rainy day without leaks, noise, orcomplaints. A solid car.
