Volvo are winning races with the C30 in the Swedish touring car championship
Volvo won the 1980 world rallycross championship with the 343 , 1400 cc 250 bhp
Volvo won the 1985 European Touring Car Championship with the 240 nearly 400 bhp in those days from a near standard high boost 2 litre B21 engine
Volvo also won the british touring car championship in 1998 with the S40 2 litre 5 cylinder engine with 300 bhp ( no turbo )
if you put your mind to it you can get great power from most makes of car as long as they have sound engineering to start with .
My speciality is the Hillman Imp engine i have got 175 bhp out of a 998 cc and a turbo charger with good results :-) Talking of which this fabulous little car won the British touring car championship in 1970 1971 AND 1972 a hat trick never repeated since by anyone with 135 bhp from its 998 cc naturaly aspirated 2 valve per cylinder engine which revs to 9000 rpm still unmatched even today except for bike engines of course
