February 21, 201511 yr Most of the old EA turbo engines that I have tested run in the 120 - 130 psi range. It's more important that they are within 5 - 10% of each other, as long as they are over 100 psi it should fire. The non turbo EA's seem to run in the 160 area from what I have seen ,same rules apply. A much more accurate test is called a "cylinder leak-down test".
February 21, 201511 yr 85 86 books say 130 for the EA82T, yet I get 150 in my 87.5 Vortex Had another non spidey that pulled the best, quietest, yet found only 60 in one, 120 in the others idled just fine, never indicated a miss of any sort - I was surprised!! Block stil to be dismantled 7 years later,but can see bore score or scuffing
