Cool! Definitely an F-1 sound. I kinda stopped reading of Cosworth long ago but only after they stopped building for Ford.
I did learn later that of all the 'makes' they worked with to develop engines, Ford's engineers were the most involved and most helpful over the years ( F-1 V-8 Cosworth/Ford, setting an F-1 win record no other engine will ever touch) since they had finished with the also successful DOHC 255 CID Indy car engine program. 135 F-1 wins alone IIRC and even more in Indy cars and FIA sports cars. It's called the most successful racing engine across multiple venues of all time!
