location involves my downstream EGT sensor. I was previously seeing temps in the
700F range. At first I was amazed that there would be this much temperature drop
through the turbo and was impressed that the turbo could absorb that much heat
energy from the exhaust. However my probe is located approx. 12" and 2, 90degree
bends downstream from the turbo. Could it be that it is just cooling off that
much? I find this very hard to accept as well. >
The turbo is supposed to be extracting energy from
the exhaust stream. Basically it is converting heat energy into mechanical work
by expanding and cooling the exhaust. I haven't done the calculations, but a
700F drop in temp across the turbine doesn't sound unreasonable. I think you
lose very little temperature in 12" of pipe.
