A discussion on EGT and Exhaust back pressure on an OM606
A discussion on EGT and Exhaust back pressure on an OM606
(02-14-2020, 02:07 PM)50harleyrider just wanted to report affects of exhaust restrictions on my 606. I added a small 18" long auger style resonator to help with the drone. It did help but unfortunately increased my egt. I'm seeing 1200+ with pretty much any boost now and increasing up to 1500. Not good! I find it interesting that the EMAP hasn't increased much and still stays within 1.5 x boost yet egt's increase. I have 2.5" now with a cherry bomb glass packed muffler, resonator and a 12" long diesel cat. Every one of these components affect power which sucks. The donor car was quiet in the exhaust and it was 2.5" with all the same restrictions I have and more. I know the little KKK waste gated turbo wasn't much on boost. I would love to know what the oe egt's were. I'm gonna play a bit more with decreased fueling and see what point the higher A/F ratio kills power but decreases egt to ~1350 max.
