Hi folks I am considering monitoring the temperatures of each cylinder bank. The question now is where I can measure the temperature. In the collector flange or at the top of a cylinder e.g. 7 + 8 ? Has anyone ever measured the temperatures of all 8 cylinders?
Many of the top dyno operators will want to monitor all 8 ( or however many ) cylinders at the Exh flange of the head at the same time so that 8 separate pulls do not have to be made. Making checks at the collector is no going to tell you what you want to know ! One builder / dyno owner who now is unfortunately retired passed along this great bit of info to me a few years ago . He said that by doing enough EGT test over the years he found that Exh gas temps of a cylinder will rise 30 to maybe 40 degrees for every degree of timing that the cylinder wants, but does not get! A well designed Intake ( Mainly single plane ) is crucial to achieving this kind of even fuel distribution!
I have 2 in my headers. 1 on each side. There is clear instruction on where on the pipes to put the probes to get a proper reading. They can't be too far or too close
In the snowmobile race World there is no other way but to monitor egg’s separately. Super common or more likely than not that the pto side, middle, (if three cylinder) and secondary side would be all jetted differently.
Riv's use a over temp sensor at the 7/8 position. It screws into the cylinder head in one of the back accessory bolt holes.
