Hi all!
I have seen this car up close, and even sat in it.
It was made for the Road And Track Supercars Manufacturers Showdown.
Since the 20th TTA here was one of them, here is alittle bit of info that I gathered so far.
This car was put together by PAS, for Pontiac. It was a engineering exercise car.
According to Dave Turra (going by merory here, so the name may be misspelled-sorry), it started life out as a 1985 Trans Am. It was pulled from the line, as a enginerring car. No vin, just stayed in Pontiac, doing duty as a test car.
With the approach by the magazine Road And Track, Pontiac approached PAS to do a car. This is the car. It was put together with off the shelf parts.
Some of the differences are:
The turbo had the bigger GNX turbine housing.
The turbine exit elbow joining the exhaust headpipe was altered to reduce restriction.
Higher capacity Delco Multech injectors and a heavy-duty fuel pump were used.
The ECM chip was reprogrammed, and allowed to use 18 psi boost.
A more aggressive camshaft with altered lobe centers and lift was used.
The rear gears were changed to 3.73
The 6 speed manual was taken from a 1989 Vette.
It still used the stock production exhasut, including the catalytic converter.
With these additions, the car now had 350 horses at 4500 rpm, and 380 hp at 5000 rpm.
She topped out at 178 mph.
