My mate Mark Sutton (of Sutton Images) spends most of his time wandering around track side with
his cameras, said they seem to have got a bit louder since the first race, I'm sure they are working
behind the seen to increase the sound, but its the old story with turbo cars, you turn the sound into BHP
so you cannot have both..!!
My old Rx7 tells a different story, lol
I also assume you have an energy recovery system associated with the turbo on your Rx 7..
