Why do some naturally aspirated cars like those sound like they got some kind of turbo in the higher revs?
Gearbox whine?
Why don’t racing cars manufacturers mute that noise? I mean the Lotus 49 and the Mclaren M23 use the same Ford Cosworth engine, in the McLaren there’s no whine, while in the 49 there is.
Same goes for turbo and superchargers: some are almost unnoticeable, while others are louder than the engines themselves. Don’t racers get anoyed by hearing the whining, especially in endurance racing?
While the Lotus 49 and the McLaren M23 used the DFV Cosworth engine, they used different transmissions. If I recall correctly the 49 was equipped with a ZF 5-speed 'box, while the McLaren had a Hewland FG400 (the same found in the 49B).
And racing car manufacturers don’t “mute” that noise because a)they don’t care, all a racing car has to do is go faster than the competition until it doesn’t pass the finish line and b)they can’t.
Pretty sure when you are tearing around a track at 150+ and your life depends on you staying focused you don’t really notice a bit of whine. And you know what would be way more annoying? Sitting in a 120° cockpit for 3 hours and getting dehydrated due to a broken drink system.
does it sound like this?
Thanks
kinda, more like this to be more precise:
I just didn’t understand why those cars sound like they have turbo or superchargers when they are actually naturally aspirated. And from what I understand now, it’s other components that are making the whining noise, like the gearbox/transmission.
I’m going with drivetrain. Ever driven an older Subaru IRL? They almost sound as if the’re supercharged, but the screws are UNDER the car.
