INJECTOR HISTORY

      In 1957 Scott designed the Scott injectors and Scott and his business parter, Ron Hess made the patterns and did 90% of the machining in a small shop in Santa Monica, California.

  Scott Fuel Injection business was more or less a hobby, not a full time business as Scott was working full time as a test engineer and his partner, Hess worked full time as a cabinet maker. Scott wanted to design a fuel injection system that was so inexpensive that everyone could buy one, so Scott came up with the simple system that bolted on a 97 carburetor butterfly base and sold for $24.95. When Scott decided to build injector for blowers he decided on the centrifugal pump because they don't have to be flowed. They all pump the same pressure and volume and there are no gears or veins to wear out. There's no reason for a bypass as the fuel recirculates in the pump, a desired feature, as there's always a head of fuel available when the throttle is popped open with no pressure drop. Scott used Stromberg carb jets in the nozzles of all his injectors as they are accurately drilled, inexpensive and readily available. Scott injected above the butterfly as the fuel is better vaporized when it passes with high velocity around the butterfly during idle. When the throttle is opened the fuel is deflected off the butterfly for better distribution.

  Scotts injectors were unique as Enderle,  Algon, Kinsler, Crower, like Hilborn, used positive pumps, bypass jets, aerated nozzles and injected under the butterfly. The Scott injectors used a centrifugal pump, no bypass, no aerated nozzles and injected above the butterfly. The positive pumps on the other injectors were Tuthill designed positive pump parts installed in their own castings. Scott designed and manufactured the centrifugal pump.

  Scott injectors dominated in 1963 winning the NHRA world's championship Roy Davis, NHRA National champion Hirata and Hobbs, world series champion and runner up Dick Vest and Speed Sport, UDRA Top eliminator Sandoval and Madden.

  Scott built injectors from 1957 to 1966 when Scott went to work for the US government as an engineer in Southest Asia. On May 20, 1964, Scott Engineering appointed Mickey Thompson Equipment Co. as their sole distributor for the Scott Super Slot fuel injection and agreed to purchase a minimum of 240 units per year. (I have a copy of this agreement)

  Scott returned to the US in 1970 and designed emission controls for the Califonia NOx retrofit program. He licensed his patents to STP Corp and worked for them as a consultant until 1979.

  Scott designed, made patterns and built several centrifugal pumps for fuel injection. These pumps were used on Butch Blair's top fuel sand dragster and top fuel dragster. The sand dragster set an all time record for 100 yards of 2.26 seconds at 147 MPH. The E.T. record still holds. The top fuel dragster finished third in the NHRA world's finals in 1988. Scott also designed and made patterns for several four throat throttle body fuel injectors.

  Scott discontinued fuel injectors for sale in 1992 but still makes a few for friends.

  In 1988, Scott designed a high speed centrifugal fuel pump 16,000 RPM which flowed 60 GPM at 200 PSI. This pump was used on Butch Blair's top fuel dragster. Scott used the Enderle hat and modified the Enderle barrel valve to accommodate the centrifugal pump with this set-up; Blair won the last Bakersfield Fuel and Gas Championship at the old Fomosa Drag Strip before it was repaired and modified to meet NHRA specifications.

What is Mel up to these days ?? He's currently working on a jet powered Jr dragster that should be capable of 100 MPH. See links below to view pics of Mel and a few of his latest toys.
