My foam tire car has the 18t pulley's and a 96t spur mated to a 47t pinion and makes a FD of 4.42 for my tight 75'x50' carpet.
My rubber tire car has stock 16t pulley's and a 88t spur mated to a 47t pinion which makes a FD of 4.56 for the same track.
The car has plenty of punch and horsepower with my novak 13.5
