ssaunders 199 Posted July 7, 2015 Report Share Posted July 7, 2015 Hi All, trying to get and idea of what EGT's people are running?i have been fiddling with the ECU on mine as i was getting AFR of 12.5-14 while cruising, i am now getting close to stoich but my EG temp is up around 850-900c, is this right?any guidance gratefully appreciated.cheerssteve Link to post Share on other sites
c00k 435 Posted July 7, 2015 Report Share Posted July 7, 2015 (edited) 85-90c I guess you mean. 900c the head would melts lol. Aluminium melts at 660c Mines about 80-87c depending on out side temp. When giving it some, raises to about 93-95c after a per longed period. Don't think I have ever seen mine over 97cEven on a boiling hot day. I do have aftermarket electric uprated fans.

ssaunders 199 Posted July 7, 2015 Author Report Share Posted July 7, 2015 (edited) sorry, im talking about a pyrometer its in the exhaust manifold before the turbo, not engine temps, exhaust gas temps.si have been reading and there are some running EGT's of 1000C different cars though.

FishWick 21 Posted July 10, 2015 Report Share Posted July 10, 2015 850-900 isn't too bad, just watch it doesn't climb too far past 1000 on boost. Try adding a bit more cruise timing if you want the egts a bit lower. For example, on my VR Turbo with flat top 8.5:1 forged pistons, I was able to run 40 deg advance at low loads at 80ish mph. That knocked the EGTs down a bit. Stock timing is around mid 30s up there, but is 10:1 CR. There's a fine line with EGTs. Running rich can increase them, running too lean can increase them, you just need to find the sweet spot with the right AFR and timing. Bealieboy 1 Link to post Share on other sites
