    Hi,

    I am doing research on a turbo vane sensor for the 6.6 GM Duramax. The sensor rides on a cam which entail reads the position of the vanes. I am curious to know how hot that sensor will get. If the EGT is about 1200F, and the turbine housing is 1200F then wouldn't the sensor which is bolted to that housing be 1200F?

    Also a generic question, what temperature does the turbine shaft reach at the bearings? Typical engine oil is 250F maximum before breaking down. Does the temperature drop down from 1200F to 250F at the bearings using oil as a form of coolant and lubrication?

    btw I am a mechanical engineering student!

    Thanks.
