Bit of an open ended question as I am looking to just learn a bit about the subject.

So what causes a turbo to surge? Why do some turbos surge and others do not? What can be done to stop a turbo from surging? Does the exhaust housing size have an effect, or is surge all on the compressor side?

On the VF35 for example I know many experience surge when having fitted an induction kit (myself included) what difference does an induction kit make that it encourages surge? Is returning to a panel filter the only way to prevent the surge? Does anyone get surge with the original filter in place?

I look forward to reading any responses!

No thoughts on this?

 

From what i understand its caused by taking in more air than the turbo can cope with.

 

So would a larger exhaust housing solve the problem? I've read of people fitting the P18 or P20 exhaust housings to a VF35 and it nearly sorting the surge.
