TRAXION's 1990 IROC-Z (sold to 92 Formula)

The Car

I bought the car in February of 1997 with 22,000 original miles. It still wore the Gatorbacks that it was delivered with from the factory. The car is an original L98, N10, G80, G92 car of which less than 1000 were made. I told myself that I would not modify it until it was paid off ... yea right. By the time the car was paid off I finished a full head/cam swap that catapulted me to 12.58 @ 107.9mph while still running the long runner type intake. I upgraded to the MiniRam and was running 12.24 @ 112mph. Now I'm running mid-11's naturally aspirated on the stock GM shortblock. I'm addicted. The car looks totally stock from the outside ... imagine the surprised expressions of those who think this is just another whimpy TPI IROC.
