Pontiac Pavement Pounders Shootout - Lone Star Edition, Part III
Owner: Mark Caughey
Owner Bio
Mark Caughey, an analyst by day, has been racing for just three years. He cites his reasons for building this particular '99 T/A as the body styling, the V-8 engine, and the rear-wheel drive. What does he like best about driving his T/A? Pulling the front wheels on launch. Can't argue with that. Currently, the car is being built with a 408 engine and more power. | Strip Specs | | Year/Model: | '99 Trans Am | | Race Weight: | 3,480 lbs | | Curb Weight: | 3,340 lbs | | Fuel Level: | 3/8-Tank | | Type of Fuel: | 104-Octane Sunoco | | Engine: | '99 LS1 | | Cubic Inches Before/After: | 346/346 | | Built By: | Real Performance Motorsports (RPM) | | Programming: | Custom LS1 Edit by Chris Robinson | | Air Box: | Texas Speed and Perf. 78mm lid, no filter | | Fuel Injectors: | SVO 30 lb | | Intake Manifold: | LS6 | | Throttle Body: | Hand-ported stock Mark Shaner S2 | | MAF: | 78mm, screen removed | | Fuel System: | Walbro 340 255 lph, stock line & reg. | | Heads: | LS1 Gallant Technical Performance (GTP) Stage II, 2.02/1.57 Ferrea valves | | Flow Numbers: | 300-cfm intake at .600 lift at 28" of water | | Pistons/Rings: | Stock hypereutectic | | Rods: | Stock powdered | | Compression Ratio: | 10.2:1 | | Crankshaft: | Stock | | Rotating Assembly Balanced: | Factory | | Camshaft: | RPM 4, hydraulic roller, 232°/236° at .050, .601/.595 (with 1.7:1 rockers), LSA 114° | | Installed Position: | 4° advance ground into cam | | Rocker Arms: | Stock 1.7:1 roller | | Ignition: | Stock coil on plug | | Total Timing: | 22° | | Exhaust: | FLP long tube headers 1 .75" primaries, 3" collectors, 3"-2.5" Dr Gas X-pipe, 2.5" Magna Flow mufflers | | Power Adder: | Nitrous Express 2-Stage, MAF plate system | | Transmission: | Turbo-400, built by John Goebel, reverse manifold valvebody, Pro transbrake, Ultra bellhousing | | Converter: | Precision Industries, 4,000 rpm stall, GM #7 pump and multi-disc clutch | | Shifter: | B&M Pro Ratchet | | Rear: | Moser 12-bolt Posi , 3.73 gears | | Brakes F/R: | Baer EradiSpeed disc with Hawk pads | | Wheels F/R: | Weld Prostar 15x3.5/15x10 | | Tires F/R: | M/T ET Front Runners/28x10.5x15 M/T ET Drags | | Tire Pressure F/R: | 30 psi/13 psi cold | | Suspension Fr: | Eibach Pro Kit springs, HAL shocks, BMR tubular lower A-arms and K-member, stabilizer bar removed | | Suspension Rr: | Eibach Pro Kit springs, HAL shocks, Wolfe Racecraft rear sway bar, Global West adj.
