Well Willk, I always thought it was wide open throttle, but you do raise a good point. Many people claim top speeds which are hard to believe.

Is WOT still used for engines that don't have a carburetor as strictly speaking the throttle is the butterfly valve in the carb?

All petrol engines will have a throttle.

And most fuel injection systems have a butterfly valve too.

The valve controls the amount of throttle, if anything the butterfly only decreases the amount of air flowing through the throttle.

It's called a throttle because the butterfly valve / flap throttles or strangles the air flow ; )

All except BMW AFAIK. They control inlet valve lift electro-mechanically to throttle airflow

And also, most small 2 stroke outboards control the first half of power curve using timing.
