Everyone's different I guess. But personally speaking - I love the screaming sound of a boosted turbo, I love the burble of a good V8, I love the howl of a big bore supercharged motor... But I also love that beautiful mechanical symphony of a high-RPM screamer in good motorbikes, Ferrari's, etc, and this... http://www.arielmotor.co.uk Ariel Atom - 2.0L Honda iVTEC, supercharged, with a huge ram-air intake behind your left ear... 300BHP and 8500rpm soft-cut limiter... Induction noise anyone? My favourite ever drive-past noise was what I am absolutely SURE was a black SL65 AMG... There was no "V12 biturbo" badge on it, but it was convertible, had quad pipes and was about the meanest vehicle I have ever seen... Not too loud (which I like), but the note, the quality, the mechanically smooth yet animal howl as the guy planted it... the undertone of the tyres scrabbling for grip being drowned out by the exhaust and watching him slingshot away like I was standing still (sorry guys, but I was in a standard XR6T and I didnt' have a chance in hell)... My missus told me to stop drooling, wipe the tears from my eyes, and wind all the windows back up because she was getting cold... ...some heartless people just DON'T understand...
