What i dont understand is why grand nationals run like hell with only .8 liter more engine and somewhat more aftermarket support. i dont think theres a single person out there that owns one with some sort of aftermarket part thats running slower then a 12.9.
Its roughly the same weight car, with a 6 cylinder turbo, rear wheel drive, with less RPM to play with, yet they are fast as hell. Whats the problem with our cars that it takes so much more horsepower/effort to get the car to run the same?
For example This turbo (

I just want to kno what the secret is with low revving small turbo 3.8's running like hell in the 1/4.
