The film Grand Prix was in the 1.5l era but not terribly accurate in a standard Hollywood way! 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. cheers Frank On 13 Jul, 2004, at 22:47, Adam Bridge wrote: > Makes me long for the 1.5L days.
