Duel thermocouples?

[JApol]

Has enyone done this or at least heard of it? I know it can be done since that how jet engines are done. The have at least 12 wired in parallel to get an 'average' temp of the gases going into the turbine. If I did use two t-couples I would put the second one pre-turbo to get an everage temperature of the tubo to get a better idea of what the actual turbo temp would be.

I have not heard of anyone on this forum running two thermocouples into one gauge. But I do know a number of guys running two thermocouples into two pyro gauges, one preturbo and the other post turbo. Most guys who do this have one analog gauge and the second is usually part of one of several performance boxes that include integrated gauges. Not sure I'd want an average, I'd rather see pre and post turbo temp's separate.

use the search feature and you will find lots of reading on dual thermocouple and alike



this has been discussed for years

I did it on my 2001 when I was anal and thought I needed all kind of information... One coupler in the exhaust manifold pre turbo, one in the exhaust pipe just after the turbo... hooked up to one gauge, toggle switch between the two lead wires to seperate the signals and it worked fine... With a flip of a switch I could tell you cool information while on the fly. . Still fried and blew up turbo's :-laf . The best place is to install pre-turbo in the exhaust manifold... Depending what year your truck is and if you have an after market manifold like ATS, proper positioning should be research to insure the best possible location for accurate temp. readings.
