We are getting way off topic, but I thought some might be interested.
Back in 1968 I was given a contract to drive a Formula 1 Brabham Repco in the "Gold Star" series, our Formula 1 championship. This was the old world championship rules. When the world went to 3.0L we stayed with the 2.5L to buy old world F1 cars cheap.
My first race was at Bathurst. I had raced my own F2 Brabham there for a couple of years, even making the podium in the F1 race.
I did a few easy laps, just cruising down conrod straight to get the feel of a similar weight & design car, with over twice the horse power. On the 4Th lap I went for it, looking for a time.
The car was not all that much faster than the F2, 180 MPH against 145 MPH, but that 35 MPH made the whole world of difference. At the second hump, now replaced by the chase as the hump was killing too many people, the car took off. It was very gentle, I did not feel it take off, nor land, but the tell tale on the rev counter said I had pulled 11700 RPM while in the air. A bit high with a 9500RPM red line. No rev limiters back in the 60s either.
I pulled into the pits to report my mistake. They didn't show much interest. Resetting the telltale they sent me back out. I thought I would try shutting the throttle as the car took off, & open it again as it landed.
I got that wrong too. The car landed with far too few revs on the engine, the equivalent of locking the rear brakes at 180 MPH. I spent the next couple of hundred yards in a huge tank slapper, chasing the tail all over the road. The flag wavers told me later they paced out from where they saw me take off, to the big black skid marks where I landed, I'd flown about 210 yards.
Having a coffee after that practice secion, I heard 2 of our top experienced drivers discussing the speed over that hump. They agreed that 150 MPH was OK, but anything over that was just too dangerous. This very relieved new chum F1 driver was extremely happy to use that as my guide.
I am probably lucky to be alive. A driver in a Lotus 19B was killed there the next day.
