Dual EGT's

[Silvercrew]

So, while installing my pyrometer in the left exhaust manifold this past weekend I got to thinking. Would it be necessary or good to put another probe in the other side as well and wire a switch between the probes and the gauge to be able to see how each bank is doing? My thinking here is we are only monitoring half the engine with a probe in just the left side. Could there ever be, theoretically, a situation whereas one bank could run hotter than the other? Another probe and wiring is about $60 and I figured why not, unless someone here can chime in as to why not. Overkill?

We have done it in big rigs with V8's. Its good for figuring out which bank has a dead cylinder or stuck open injector.

Not a bad idea. Like Ryan said, big trucks with V8 CAT and Detroit two strokes will usually run doubles...I may eventually, or actually run two gauges...

generally you will know if there is an issue and fix it. why need to see 2 egts all the time? imo not nessary. unless you want to get gauge happy.

I always thought that would be a good idea to run twin gauges for each bank. the high dollar drag cars will run 8 of them in each primary. My buddies twin turbo SBF Hatchback Stang has small egt probes in each primary, easy to trace down an injector issue, or just a tuning issue in general and add more fuel to one injector to keep from burning a hole in a piston or installing a window in the block

in this case for racing yes i can see the need for it. but for the average joe, unnecessary.
