The loud noise comes from the wheels of my Mazda MX 5 Miata

If it is one of your tired bearings, it will tend to make a thumping noise that intensifies when it is under stress (spins faster and faster). So keep in mind to check by driving “fast” (neutral gear on and window open to hear only the noise of the wheels) that the noise is located here, if this is the case change it or them quickly. If it is a deformed tire, make sure to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Mazda MX 5 Miata that is the problem, you will tend to feel a vibration in the direction of the car as you go faster.

In the first case, a turbo failure may also be connected to a compression loss during the engine ramp-up phase, so you should experience a power loss during your acceleration. If the loud noise on your Mazda MX 5 Miata is related to air intake, the control will be done mainly visually, check all your air intake hoses by a visual control in your engine block to be sure that it is not damaged or disconnected which would cause an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then check that the engine idle speed is not random. In case you confirm one of these two trouble, take your car to your service garage .
