I have my EGT post turbo because I find it more useful to be able to see how all cylinders are doing. One a stock frame setup you can only see the temp of two cylinders unless you run a second probe. I was asking those questions to see if anyone was running a two probe setup.
I don't use EGT for tuning, merely as a health check. If I see temps lower than normal I know I've lost a cylinder or something is potentially wrong.
1 and 4 are the hottest most people go with cylinder 1 when installing the egt probe
Ideally you would have 4 of them, one in each runner... that way you can check your fuelling ballance. Post turbo EGT is pretty useless as the turbo will lower the temp a lot..
Yes but having 4 gauges is not realistic save the extreme 99% setups. I know turbos lower EGTs, it's a form of energy conversion (thermal to kinetic) but only watching 1 cylinder doesn't tell you if there's a problem with the other 3.
yes but 1 post turbo EGT tells nothing really... better just have some sort of automatic wide band based alarm..
I dont have the egt gauge.. just log it for tuning purposes.. And that is really the only reason to have 4 EGT probes.. to see if the fueling in the individual cylinders is balanced.. Having 4 widebands is difficult due to the corrections you have to make because of the increased manifold pressure..
Cant say how this stuff would work on the inside ,as intended, but it's holding up well on the exterior. Been daily driving and doing pump gas tunes. Looks as good as the day I sprayed it. Not bad.
