I heard a similar story once of a guy with a 4cyl Ford Ranger, they hooke up, not NO2 but OXYGEN!!! Not the stuff you air your tires up with Im talkin PURE OXYGEN, EXTREMELY COMBUSTIBLE! He did a simlar setup. They said they took off and hit the switch, the guy said it took off like a rocket for like 2 or 3 seconds before the engine nearly literally BLEW UP! There are some VERY smart people in this world.
