Since the 60`s, Top Fuel Hemi and funny car have used the 426 Hemi design. Back then they made about 1,500HP, but the teams always search for ways to increase those numbers in order to get an advantage. However, the newest technology allows the teams to make 11,000HP with that same basic design. One of the things the teams have done is actually set the supercharger back on the engine. That makes the fuel and air mixture going into that engine much more efficient. The standard firing order for the 426 is now 1843 5672. They switched 7 and 4 in the firing order.
