compression test #'s..what to expect..
Going to run a compression test on my D16z6 today with JE 9:1's and Scat Rods(stock length) was wondering what would be considered good numbers to see being that I can't go off stock specs.
or, should I just be looking for consistency here??

Make sure you do the test on a warm engine with all the plugs out, injectors unpluged and full throttle. Count the revolutions to keep it consistent for all cylinders

you want the throttle plate open. i usually do 6 cranks of the engine.
at 9:1 id bet you will be around 180psi. anything consistent and over 170 or so should be good
