Osella PA9/90 BMW Engine Pure Sound In Action on Hillclimb!

Osella Corse is an Italian car brand specializes in building sport cars for hill climbing and minor sport race championship. The car featured in the video is the Osella PA9/90, a historic hillclimb prototype built in 1989 as an evolution of the PA9 (1981). Most of the PA9/90s were moved by a 2.0 liter BMW M12/7 engine which was able to produce around 300 bhp at 10000 rpm. Afterwards it was adopted a bigger BMW engine (the 2.5 liter S14) that had more torque than the M12/7. In this video you can hear the sound differences of the 2 engines. In particular the first PA9/90 (yellow) has the 2.0 BMW M12/7 engine instead the other two (light blue and lime yellow ones) are moved by the 2.5 BMW S14.
