In reviewing several Car Model magazines from 1968 and 1969, it seems remarkable that we run 1/24 scale cars at about 160 grams (5 1/2 oz) versus about 105 grams (3.7 oz) today. Todays cars are about 65% of the weight as back in the 60's! Now I know that we had alot more HP back in the late 60's, but how would the lap times stack up? Of course, the track voltage would matter a lot.
In the June 1969 article, we (NE Ohio racers) raced on the 220ft Engleman in Brooklyn, Ohio. TQ was Gil Pataky turning 15 laps and 39 sections in 2 minute which works out to be approximately 7.6 second laps without a de-slot. I am guessing that we might turn around 5 second laps today if we could run on the same track with todays cars. (Yes, I am reliving the late 60's today.)
EDIT: I corrected the lap time above based on Mike's insight that it was 2 minute qualifiers, not 1 minute.
