Hi Adam,
I was just a fan in the 1.5l days but I don't think the rpm ever 
reached 15000, they did give over 200 bhp though. The film Grand Prix 
was in the 1.5l era but not terribly accurate in a standard Hollywood 
The 3l cars started in 1966 I believe. There was a provision to allow 
supercharged 1,5l units but nobody took it up until Renault in about 
1977. Interestingly one of my university professors proposed a 1.5l 
turbo alternative to Hesketh (via me) but his power predictions were so 
high that Hesketh did not believe them. At that time a Cosworth DFV 
gave about 480bhp, Neil Watson calculated 700bhp from the turbo. He was 
proved right before his untimely death, we were racing with 1000bhp in 
1987 using the 1.5l turbo.
Our current 3l engines give about 900bhp and can run to 19000rpm for a 
limited period.
