The pulsejet – a type of jet-engine which combusts fuel in pulses – is no modern creation. Its roots trace back to the 19th century, though it’s remembered best for its role in World War II as the powerplant behind the German V-1 cruise missile. Though not the most efficient engine in the world, it can produce some serious speed, which explains why Maddox decided to build a salt flat racer around one.
At its core the ‘lakester’ is comprised of a P-38 Lightning fighter plane drop tank, worked over by legendary custom car builder Randy Grubb. Inside, a steel space frame supports the body as well as the stainless steel pulsejet engine fitted in the back. Upon ignition, six high pressure fuel pumps shovel gasoline into the jet, generating up to 550 pounds of thrust and eating between two and six gallons of fuel every minute.
In the listing, Maddox describes the car as more of an art piece than actual record breaker, especially given its classic post-war styling cues. But after seeing and hearing this thing fire up, you can be pretty sure it has the speed checkbox pretty well ticked.
