I had that happen to me about three weeks ago. I pulled up to a light at Dale Mabry and Kennedy. I saw a white 92-95 Civiv hatchback. It was lowered had a small AEM sticker on the side and that was it. No exhaust no wheels and it didnt make a sound. I figured it wa just another hatchback. The light turned and i I instantly pulled about a car in front of him. Then he hit second gear and flew past me like I was rolling backwords on a hill. I have never been beaton so bad in my life. He beat me worse than one time i tried supped up firebird. We caught the next light and I watched him. He gunned first gear didnt really go that as he hit second gear I seen his hand reach down and then he was gone. I really do think it is NOS but I never did get to ask him. (He was to far ahead!!)
