In the first place, I don't care for turbos or nitrous, anyone can give a racehorse drugs to make it win.
True streetcars aren`t going to run great numbers w/ street gearing in an 1/8 mile. They will do better in a 1/4. And most people don't have gear vendors , or overdrive automatics in 50 yr. old cars.
Adding a turbo "totally" changes the set up, how many outlaw cars do u see being driven to work !?!
