My mustang did 0-60 in 5.0 seconds stock, I swapped for 4.10 gears and got it down to 4.8 seconds.
I then added a supercharger that added an extra 240 crank horsepower (480 to the wheels 260 to the wheels stock).
The car can do 0-60 in 3.2 seconds with slicks, and it still can't do 0-100 in 6 seconds. Probably like high 7's to low 8's. Don't exactly know. HP to weight ratio of 6.8lbs per horsepower.
This FIAT has 135 horsepower, and with the upgrades we're looking at around 200 horsepower. No way in hell that thing gets even 0-100 in even 10 seconds. HP to weight ratio of 12.5 lbs per horsepower at 200 hp, 18.5 @135 hp.
My vette will do 0-100 in like 9 seconds, with a 3.8 0-60. HP to weight ratio of 7.17 lbs per horsepower.
