May 31, 1959, Riverside Raceway: The Russians dominate the heavens with Sputnik, a satellite designed to determine the density of the upper atmosphere and return data about the ionosphere via a pair of radio transmitters.
It’s Memorial Day weekend – when the US of A honors its war dead – and Eisenhower/martini-shaker America is having enough problems coming to terms with the Russkie’s satellites that continue to buzz the stratosphere whereupon an Ozzie & Harriet-type couple is motoring down the surface streets near Disneyland and they encounter what looks like a spaceship strapped-down on the back of a flat, open trailer, being towed by a 1956 Chevrolet station wagon.
In the front seats of the Chevy are a couple of beat looking young men, “Jazzy Jim” Nelson and “Jocko” Johnson. In the back is a lone black man, pit man Eddie Flournoy.
As the couple pass the spaceship-time machine looking thingie, they do a double take. The Harriet-type drops her jaw. The Ozzie-type scratches his crewcut. As disturbed as they are about the Communist threat of interstellar superiority, they are unsure if these are the guys they want on “our side.”
After Jocko and Jazzy unload their streamlined dragster off of the trailer, the world stops in its rotation: On this day, the Jocko’s Porting Service entry, a rear engine dragster blanketed in aluminum lovingly hand-formed by Jocko, sets a 1/4 elapsed time record, as driver “Jazzy Jim” stops the clocks in 8.35 seconds. To Jocko, it is an empirical display of the equation wot says: horsepower less drag equals an ungawdly acceleration. His stealthy car slithers through the slipstream and into the history books.
In a direct contrast, at an Air Force base in Kansas, Glen Leasher in the Sullivan, Martin and Leasher AA/Fuel “rail” claims a 1/4 mile speed record of 185 mph the day before…
Dragster were called “rails” or “railjobs” for a reason: They were either sedans stripped of all body work or were purpose built chassis that were nothing but tubing. Jocko’s Porting Service was different: The damn thing looked like it was from another planet, but was influenced by various land speed record setters such as the Bluebirds of Malcolm Campbell, George Eyston’s Thunderbolt and the Railton Special of John Cobb, which, at the time of Jocko and Jazzy blasting into the record books, held the Land Speed Record at 394 mph for over a decade.
(To avoid confusion, it helps to remember that the Land Speed Record is the average speed between two timers set exactly one mile apart. This is after a running start of as much as six miles. It is the average speed of two timed runs, back-to-back within an hour, run in opposite directions. Conversely, drag racing records are measured by timing lights triggered 66 feet before the finish line and 66 aft, for a total distance of 132 feet, which is 1/10th of the distance of the race course (a 1/4 mile equaling 1320 feet.)
Because the drag strip runs are more of a sprint and less of a marathon, the use of nitromethane – a highly destructive fuel – was used by drag racers such as Jocko Johnson, whose specialty was “porting” the cylinder heads’ combustion chambers for burning nitro, a rather delicate science as the porter had to re-engineer the heads on an engine designed for a passenger car that would normally burn gasoline. Johnson had “porting” down to a science, but he was the first drag racer to also factor in the science of aerodynamics, which had previously been the domain of the Land Speed Record guys and aerospace.
Although the LSR crowd had tapped into decreasing both wind resistance and drag, they did not utilize exotic fuels in the rather prodigious amounts that the dragster guys did, who had no fear of “tipping the can” with the “yellow stuff” or “liquid horsepower.”
The LSR competitors made horsepower another way: with gobs of cubic inch displacement, via engines that had come out of fighter planes. To see these giant, beastly machines blubber down the Salt Flats of Bonneville with massive puffs of black smoke billowing out of the exhaust was a truly unique spectacle.
(In the 30s, the Germans had burned nitro with an automotive, streamlined vehicle, albeit with tragic results: Berndt Rosemeyer, a national hero of the Third Reich, was killed while racing on the autobahn at a speed of 280-something mph in the Auto Union GP, whose design pre-saged that of the Top Fuel dragster (supercharged engine, with nitromethane as a fuel) by a quarter of a century . The Auto Union GP was ultimately co-opted by the Third Reich, much to the consternation of Ferdinand Porsche, the car’s designer, who ultimately shuttered the project, as a political gesture as much as anything else… )
But the salient point among all of the digressions is the reality that Jocko Johnson had created a package that had the best of both worlds: a streamlined dragster that had plenty of downforce without much drag (the opposite of thrust) and aided by a powerful badass hemi, huffing on nitro.
Streamlining rarely paid off on the drag strip. The weight penalty of the added body work negated the benefits of slipping through the air stream.
The Jocko’s Porting Service ‘liner is history’s exception.
