I was in more shock than anything and thankfull that the rest of the turbo stayed put
Spoke with a guy (didnt catch his name) from Universal Turbos and he was as shocked as we are, should be a direct replacment exhaust side housing and shaft.
Send it off tomorrow and see if if they can put a reason behind it.
Blessing it fell out when it did when the car was parked up. It was not cherry red but as my mate picked it up of the floor i could tell by his screams it was still pretty Hot
It could have made a right ole mess of someones car if that had come out on track at speed
