Normally Top Fuel is the fastest class around however I've decided to go with a blue drag arm since it makes nice torque off the starting line but doesn't usually produce blinding top end speed. The reason for this is that I don't want to see anyone's beautiful creation take a wall-shot and destroy the time & effort that a racer put forth to build a detailed Top Fuel racer.
