Hi all i did a static and a running compression test today on my 04 Es2 and i was wondering what the specs were for both. for the static my compression is about 170 in each cylinder and for the runnig it was about 80 at idle and 50 at 2000 rpm's. Anyone with the factory specs let me know. Thanx.

 

how do u do that?

 

I don't know what the spec is for a d17, but its more important that
1) they are all within 15psi of each other
2) they build pressure quickly
3) they don't loose pressure after you stop cranking

but I'd say that 170 doesn't sound bad for a d-series.

 

170 sounds fine for 9.5:1

 

Yeah all the readings were pretty consistent so i guess it is good.
