Glosphil Posted May 21, 2007 Share Posted May 21, 2007 Want to fit my Defi EGT guage, wondering if rather than drill the manifold and put it in there, couldnt I just drill a hole in the 1st De-Catt pipe and put it there? its not really far from the manifold? Thanks Quote Link to comment Share on other sites More sharing options...
DamanC Posted May 21, 2007 Share Posted May 21, 2007 These are normally placed in the second decat anyway Quote Link to comment Share on other sites More sharing options...
Homer Posted May 21, 2007 Share Posted May 21, 2007 It's best placed as close to the exhaust outlet as possible, normally in one of the manifold runners (5 or 6 are good as they tend to get the hotest). These are normally placed in the second decat anyway Think you've got something mixed up daman The widebands go in the 2nd decat, egt's in the manifold.

DamanC Posted May 21, 2007 Share Posted May 21, 2007 Ah yes, thanks Daryl i was thinking of an AFR sensor. On that note, im off to bed Quote Link to comment Share on other sites More sharing options...
Nic Posted May 21, 2007 Share Posted May 21, 2007 Some mount the sensor in the first decat pipe (mine use to be), it is not ideal though as the reading is not as accurate. Readings are generally around 200C cooler if the sensor is after the turbo. Quote Link to comment Share on other sites More sharing options...
Pixelfill Posted May 21, 2007 Share Posted May 21, 2007 Phil, I think it's a matter of personal choice. I know Chris Wilson is of the opinion that after the Turbos its pointless fitting it. (Due to the lag introduced by the turbos acting as heat sinks) Any noticable increase in EGT will be too late to do anything about it. Other people point out that there is a risk in installing before the turbos that the tip of the sensor could break off and take out your turbos en-route to the exhaust. The counter to this argument is that you don't hear of it happening often (if at all) All you can do is make an informed decision based on the two arguments. I'll probably go for before the turbos, potentially giving me the excuse to go hybrid or single Mike Quote Link to comment Share on other sites More sharing options...
