It has been a while since I have posted and I am reaching out for some help and advice.
A week or so back when we got home and shut the engine off in the garage I heard a noise.
Today, my good friend and mechanic Liam came over so that we could try and identify where the noise was coming from.
It sounds to be right in the middle of the supercharger.
My car being a 2015 build has already had a replacement supercharger back in 2016 as many of the early cars had IHI failures.
It sounds like mine has gone bad again with maybe 15,000 miles on it if that.
It runs a 2.85 litens pulley, demon injectors with an HHP tune.
I have attached a video so that you can hear what is going on.
If it is the supercharger who would you recommend that I go to for a replacement unit, bear in mind I will need to ship to the UK.
Would you recommend upgrading to the 2.7 litre supercharger ?

That sounds like the decoupling of the pulley on shutdown..
Take the belt off and spin the blower. Does it still make full boost?

yes, it still makes full boost. We have not taken the belt off as yet. The noise does sound like it is coming from the middle of the supercharger rather than the snout end
