Does any one ever tune their engine by exhaust temp?I just started trying to use a pyrometer to check exhaust gas temp.I have a couple of hand held units.The type you just point and shoot.They where both with in about 5 degree's of one and other.I tried to point them in the same place every time.The car was pulled off the track after being hot lapped for 5 laps.I checked it as soon as it made it back to the pits.Less than a minute.They where all at about 1,050 degrees F except for the center two on both sides they where down at 1,000 F.I would assume I have a manifold fuel distribution problem. I do know the engine cooled down after it came into the pits.The engine is on alcohol.Yes, there was a group of people around me asking what in the world are you doing now?Followed by I thought you used them to check your tire temp.Have you ever tried to read plugs on alcohol at night with a flash light in your mouth? This is when I came up with this crazy idea.Anyone else ever try this?
