Yeah, that stuff was nuts! I worked with a guy who left the shop we worked at together to be the crew chief for the Norseman Racing Ford Escort. This was in the early to mid 90's. It had a Cosworth Ford single turbo 4 cylinder that made about 425 hp. It was one of the first cars to have an anti-lag system. Basically, it would fire the ignition with the exhaust valves open and it would actually start to build boost at idle if you let it sit there idling for a minute. I remember him telling me it did 0-60 in 3 seconds on asphalt and 3.5 seconds in dirt! I got a ride in it one time and he didn't thrash it because he was heading off to a race, but you could tell it was an insane ride. It was so stiff, you could feel every little thing through the seat of your pants.
