Sorry, I didn't mean that it reduced boost. As you say, it creates a load that lets boost build up. But with a mitsu turbo theres not much need to do it, response at anything over 2500 rpm is decent, at 3k rpm its instant.allessence said:It's not to reduce boost. It's to keep the engine rpms in a range that keeps boost avalible at an instant. The greater the load the more boost the turbo will produce. This is why if you are just idling the car and romp on the gas the boost doesn't really go anywhere once it reaches ambient.
