I have some logfiles from pulls on the highway. Like 60-200km/h. I can upload them later today. I have a temp sensor on the outlet of the turbo, so you can see how much heat the IC takes away. But I think I remember the highest temp I saw. It was like 160c out of the turbo and 60c in the intake. This was after several pulls and maybe at 230km/h full throttle. Then I let off because of the speed. -

Today it was time to mount the new turbo. All went well i think
Also mounted a connection on the collector to measure backpressure. Will be interesting. Next step is to make the car ready for MOT. Hopfully it will be all godd but you never know in this country...

Thanks you for the kind words. It sure will, just put a lot of time and effort in to it and it will happen
I hope I can afford to buy a new turbo so I can run it this summer. My other project (RS2) take most of my time and money right now. But the Urs4 is sleeping well in the garage.. I have to start it up some day soon.Leave a comment:

The car has been on holiday.. My turbo problem still hanging on and I don't want to risk the car to catch fire. Easy solution, buy a new precision 5858 turbo which I will do after my holiday to USA. Sorry for the lack of progress. But as soon as I order the new turbo i will let you guys know. Just need to work in the money
after that the car will get MOT as soon as possible.
