Thats interesting. I always wondered how it was achieved without modern electronics like oxygen sensors. I had read that German planes in WW2 had mechanical injection and could handle negative Gs, unlike allied carburated engines, so they used that advantage in dogfighting.
I believe the German system was like a diesel, with timed shots of gasoline under pressure to the cylinders or intake. Stu Hilborn pioneered the modern continuous flow fuel injection, like the Corvette and early Bosch CIS. I believe advances in computer control improved on what we have today where the fuel is pulsed on and off. Many knowledgeable engineers of the day told Hilborn that his system could never work. But he persevered and was very successful. Early Indy cars qualified with Hilborn Injection, ( same unit was p***ed around) but they would not race the 500 because they didn't think it would finish 500 miles. But a top (don't remember) guy ran it and finished well with it and everybody ran it then. Ago
