Lingenfelter Camaro ZL1 Tops 200 MPH!

On this episode of HOT ROD Unlimited, HOT ROD Editor In Chief David Freiburger drives the Lingenfelter Performance Engineering Camaro ZL1 to 202 mph, making it the first 2012 ZL1 to exceed 200 mph. This very same ZL1 in the exact same configuration (save for wheels and tires and the rollcage) was also the first to run 10s in the quarter mile. The ZL1 Camaros were first delivered to the public in early April, making 580 hp from their supercharged, 6.2L, LSA engines. Within days of delivery, Lingenfelter had its ZL1 making 720 hp at 6,500 rpm and 650 lb-ft at 4,650 rpm, both measured at the rear tires. The performance parts are all from Lingenfelter: CNC-ported cylinder heads, a GT9 camshaft, a ported supercharger cover, overdrive blower pulleys, a cold-air kit, 63-lb/hr fuel injectors, a voltage booster for the fuel pump, a 160-degree thermostat, and tuning. The entire package, installed, is $11,495. Everything else on this manual-trans car is stock. The performance testing was done with 109-octane VP fuel and 15 psi boost. On April 18, 2012, the Lingenfelter ZL1 ran 10.79 at 134.36 mph at Muncie Dragway in Indiana. That was on drag wheels and tires. On April 30, 2012, the car was delivered to the Continental Tire Proving Grounds in Uvalde, Texas. Shod with Continental Extreme Contact tires on the original ZL1 wheels, the Camaro was tested on the 8-1/2-mile oval. The three-lane surface is like a road rather than a race track, the turns are not banked, and there are a few elevation changes. During the top-speed run, Freiburger pulled 0.4 to 0.5 g at 190-plus mph in the sweeping turns, then held it down for nearly 40 seconds on the pull from 190 to 202.67 mph before lifting to avoid cresting a small hill at corner entry at 200-plus mph. The car had not reached terminal velocity. Conditions included a head/crosswind, ambient temperatures in the 90s, and a density altitude of 3,280 feet. The car had not reached terminal velocity. Conditions included a head/crosswind, amb
