I think this is a bit of a myth tbhIsnt wastegate chatter really bad for turbos? Its surely much better to relive the wasted pressure of a turbo all in one go than letting it go in chunks?
I'm sure i've read articles on why chatter is bad for the life of the turbo.
This is what I'd been led to believe. Would it put more pressure on the turbo constantly spooling up, backing off. If it was happening constantly, make you wonder what the ECU may do to compensate?Are you sure? When you actually think about what happens when u get chatter the blade in the turbo will be forced to slow down the allowed to spin again then forced to slow down etc...
Thanks, really good point well made. Towards the end of my Ring lap my car started to do quite a bit of this, and fortunately it's not a common occurrence, only seems to happen when pushed REALLY hard and hot, or when the revs are low in a high gear and you boot it (which I try never to do).I don't think the ECU could do anything? It presumably causes back pressure on the turbo. So you will have the active force of the exhaust gasses on one side of the turbo wanting it to spin the "normal" way then the back pressure your causing with chatter trying to make it spin the opposite way. The "Myth" apparently causes excessive shaft play (its the twisting force on the shaft and blades that will cause this over time).
here we go again....I'm trying to find out what westgate to get for my mk2 leon fr for turbo chatter but can't seem to find anyone that knows. Can anyone help with this?
