About to put an egt (pyrometer) on my turbo eco. Just curious as to what the egt should be if I'm running stoich.

4 Cams...32 Valves...5 Liters...This Could Get Fun!

EGT really isn't a good indication of a/f ratio, it gives you an idea, but then again, so does a narrowband a/f gauge...

BTW, you don't want to run stoich in boost, you'd blow the motor up.

Buy stuff from CarCustoms Ebay! Won't be disappointed!

EGT is used more for tuning your ignition timing, after you get your fuel mixture correct. I don't recall the temps and if I remember corectly, too hot is indacative of not enough advance(typically fuel still burning going out the exhaust), too cold too much advance(gas cooling has begun). It has been a number of years since I last delt with this, so if some is a little more up to date on this, please correct me.
