According to some old material i've found, the Cosworth DFV had a rather savage power band.This is odd because i dont think i've ever heard this mentioned before.You'd think something like this would be common knowledge?
It had a considerable jump in power between 6000 and 6800rpm,and that caused some problems at first with drivers spinning.Cosworth did design a special throttle linkage to help tame it but advances in downforce soon made it all a non issue.
Apparently the engine stayed that way until it was redesigned as the DFY (which had an extremely linear spread of power)

Aren't racing engines all like this to some extent? You can't expect the power band of a road going engine.

Interesting. Thanks for sharing. Cams usually have the most pronounced affect on peaky power bands. I suspect that the cam/intake/exhaust combo they were using was tuned to a very specific RPM in order to meet Lotus's power requirements.
If you have a close ratio gearbox, it's not really a problem to have a narrow power band since you only end up using a small portion of the rev range. Just gotta remember to keep them revs up though.
