Looking great Jonny.
Just one question, what if it rains - whats to prevent water going down the tube, and what potential damage could it do - None I presume or it would be wearing a hat!?!
Ohh forgot to mention that.. The dump tube was designed such that the lowest point was in the tube and not the wastegate, and then a 3mm drain hole was drilled to let any water escape.. I found out that this worked very well this morning, the car had been parked up over the weekend with it raining/snowing lots and the first time the wastegate opened there was nothing more than some very faint vapour released..
I did get a video but the camera just doesnt pick them up.. Im going to try get a cam corder with night mode and see if that works!!
