On a related note: I recently installed a hayden 403 inline and have been on one significant road trip. The highest long distance temps I saw were:

- Highway speed steady at 65mph
- Air Temp at 80 degrees
- Engine temp at exactly 1/2 (almost the exact same location as yours)
- Transmission temp @ 174 degrees

Do these conditions seem ok? The only reason I ask is the engine temp struck me as a little high but I'm likely just paranoid. I was curious if the additional heat coming off the 403 could decrease the radiator effectiveness and increase the engine operating temp.
