Everyone knows EJ Potter from his globally death defying antics atop a series of Chevy V8 powered motorcycles known as the Widow Maker. But did you know about his automotive exploits on the drag strip?

Potter built a pair of insane Allison V12 powered cars known as Nightmare One and Nightmare Too. These machines were incredible and both were relatively short lived especially as compared to the Widow Maker motorcycles. Imagine traveling nearly 150mph in these things?!

One blew up and nearly burned EJ out of the sport and the other was a car so innovative that it has features used in top fuel dragsters and funny cars today.

Here's a comprehensive look back at Nightmare One and Too, machines that blew away crowds, journalists, and even EJ "The Michigan Madman" Potter himself. Enjoy!
