| While that's true, the EGTs will also be higher from the lower compression ratios and the higher IATs.

There are second and third reasons why the TIT is typically
higher than the open-pipe EGT. The lower compression ratio
with the turbo engine means that the combustion gases have
expanded (and cooled) less than in the normally-aspirated
engine. Also, the turbo engine may have had a higher intake
gas temperature (and pressure) before compression and combustion. |
