Before running the car on the dyno with the FP3065, Barnett replaced the stock camshafts with HKS ones, the stock clutch with an Exedy twin-plate piece and a previously installed A'PEXi Power FC unit with an AEM engine management system. With a conservative tune and 22 psi of boost on 94-octane gasoline, the dyno returned 342 whp and 287 lb-ft of torque. A bit more radical tune at 28 psi matched with C-16 race fuel put down 462 whp and 367 lb-ft of torque, enough to easily beat a 5.0 Mustang. In 2006, Barnett recorded an 11.04-second run with a top speed of 128 mph at Norwalk Raceway Park.
The heavily modified EVO also sports a series of Buschur Racing upgrades including a manual boost controller, 3-inch turbo-back exhaust, front-mount intercooler, upper and lower intercooler piping and mass air pipe, TiAL blow-off valve, large open element air filter, mini-battery kit for reduced weight and size, rear strut tower brace and a carbon-fiber front lip.
Other sources also enhance this gem of an EVO, including an Agency Power fuel rail and front motor mount, as well as Ralliart spark plug wires. The stock suspension components are complemented with Tein S-tech springs, which offer a 1.5-inch lower ride height. Evodave blacked-out headlights, APR carbon-fiber mirrors, JDM MR taillights and a JDM EVO IX rear bumper fashion the aesthetic look to suit Barnett.
Seeking more power and a better e.t. in 2007, the car underwent more modifications during the winter. The Exedy twin-plate HD clutch was replaced with a triple-plate HD Cerametallic clutch, while 1,000cc PT&E fuel injectors and a Buschur Racing ported fuel pump were introduced. Buschur BF272 custom ground camshafts with 11.8mm lift also replaced the HKS setup along with a GReddy Kevlar timing belt upgrade. The Buschur camshafts are specifically designed for the GT30 series turbochargers, like the FP3065. A ported stock intake manifold is attached to the lightly modified stock cylinder head where Buschur Racing valve springs and retainers in conjunction with ARP head studs replace the stock setup. Buschur-spec, 8.8:1 compression ratio, standard-bore JE Pistons and Crower billet rods were also dropped in and bolted to the balanced stock crankshaft with ARP rod bolts for added durability. The engine retains its original displacement but shows significant improvements on the dyno by way of 398 whp and 303 lb-ft of torque on 94-octane fuel at 22 psi. On race gas and at 29 psi, the dyno reported 502 whp and 403 lb-ft of torque.
Before the Ohio snow melted in the spring, Barnett upgraded to 18x9 Advan Racing RS chrome wheels. These could carry the added width of BFGoodrich G-Force T/A Drag Radial 245/40 tires, while shedding a substantial amount of mass, weighing just 40 pounds per corner. At the first outing of the '07 season, Barnett ran 10.83 at 133 mph at 29 psi. Turning up the boost to 32 psi on a subsequent run generated enough force to break one of the rear halfshafts preventing him from clocking the attainable, but temporarily elusive 10.5 e.t.
Although the outing proved to be bitter sweet, the ride home confirmed that racing in show car trim had its distinct advantages, like watching the record-setting run replay on the Pioneer 6400CD stereo/DVD head unit's 6.5-inch LCD display as the sunlight gleamed off the weightless white finish that resembled light reflecting off a polished gem.
