Scott Posted January 31, 2015 Share Posted January 31, 2015 Currently I'm idling between 550 and 600degC. This seems high compared to what I had previously, but previously I was in the down pipe off of the TT cats, rather than in runner 6 right off the manifold. Does this sound about right, or is the timing a bit off? Thanks Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted January 31, 2015 Share Posted January 31, 2015 I only used to see about 350-400c in the turbo housing during idle. Link to comment Share on other sites More sharing options...
secondjump Posted February 1, 2015 Share Posted February 1, 2015 Mine used to sit around 500 to 550. Using runner 6. A lot of guages are not that accurate, so don't panick if people are quoting slightly different readings to you. I'm more interested in what you are seeing on boost?

Lee P Posted February 1, 2015 Share Posted February 1, 2015 That's fine for runner 6, hottest place so best place for the sensor to be mounted Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted February 1, 2015 Share Posted February 1, 2015 It will all depend on the mapping anyway, the best sensors are Inconel type, but you will obviously need decent electronics to read properly, I used to use Red-line gauges, which where intended for aircraft.

Scott Posted February 1, 2015 Author Share Posted February 1, 2015 The car isn't mapped yet. Just wanted to make sure it wasn't TOO extreme. Happy to factor in 50+/- degrees just for the gauge. As long as I'm not 200 over what I should be I'm happy for now. The idle is a little lean also so I'm guessing that will add a little to the EGT. Thanks for the info guys, set my mind at ease Link to comment Share on other sites More sharing options...
CanisLupus Posted February 1, 2015 Share Posted February 1, 2015 Also depends on Idle Speed. I'm having around 350-400°C with E85 in the first runner(around 2-3cm from the head) and around 70-100°C more with Normal Fuel. Idle sits @900rpm with 264 Cams(depending on their shape there will be an EGT Difference) But on Idle there won't be any difference between 1st and 6th runner.
