Some of us like revvy, high pitched and eardrum splitting petrol engine shrieks, some like low frequencies than anything else, some like the high pitched gas turbine sounds and some even like the lumpy V8 sounds with cams too aggressive for smooth idling.
No, I'm NOT deaf. Am I the only one here with hearing good enough to hear the R10's turbo? I'm more familiar with diesel exhausts notes than many if not most here and all I can say is that high revving turbodiesels (not the 2500rpm bus engines) make wonderful exhaust notes that just say smooth, effortless drive. I wonder if people here have any familiarity with turbodiesel sounds at 3000+ to 4500rpm or even 5000rpm on some eurodiesels.
