I just did a compression test and my numbers were cyl. 4: 286psi, cyl. 3: 280psi, cyl. 2: 280psi, cyl. 1: 280psi. My engine is a b18c1 with 11.6:1 static compression. i was just looking for some input as to what u think of these. I beleive there pretty good, especially the only 6 psi variance.

 

Thats a completely healthy motor.

what cams, and that seems like more like 12.7/1 compression, 300 is about 13/1 with most decent cams. did you check it wide open about 5 pumps

i'm 250 across the board, when engine is cold, when the engine is warm i hold 265 across the board, mugen 1 layer HG, ferrea high compression flat face valves, jdm b18c head on a 97 usdm type-r bottem end, i'm told i'm somewhere around 11.6:1 ~ 11.8:1 ..i'm sure your numbers are about right infact, ur compression might be alittle bit higher then what you think.
