Bone stock these cars ran 13.50 @ 103 mph. There were WAY UNDERRATED AT THAT TIME (250 HP). If you look at my sig, you'll see that with bolt-on mods ONLY and a set of Gatorback shaved "S" compound tires, the car ran a best of 12.18 @ 115 mph. There was no computer tune, just an adjustable boost control that let me run 20 lb of boost in all the gears instead of the factory setting of 16 lb in 1st/ 14 lb in 2nd and 12lb lb in 3rd. If you figure the weight of the car, that translates into about 450 hp and all from a 3.8 V/6 stock block. One hellva sleeper. It did handle better also because of less up front weight and still got 28 mpg on the highway with the stock 200 R4 trans. These GTA's were actually modified near the Van Nuys plant AFTER they were fully built where they stripped out the motor and trans and brakes. Then the baffled gas tank went in, the motor, the trans, the boost gauge in the tach pod, the REAR seat headrests (from the notchback), the dual/dual chrome exhaust tips and the 1LE brakes and aluminum driveshaft. At that time it was the ONLY GM vehicle that could do 0-100-0 and still not have any brake fade after 10 straight runs. The dealer also had to pay over $7,000 UP FRONT before they would ship the car. This was the cost of all the mods that this outside source performed.
