@edwardmtl the road noise drowns out the whine. its actually more like a whistle and is constant between about 2500-4000 rpms at around half throttle. also does it quickly when giving it more gas quickly while driving. its not really loud in person but you can still hear it easily. its almost like a turbo spooling up but muffled. actually i just listened again and cant even hear it. i think the sound got converted or something since the last time i listened to it on youtube.
