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??

 

im about 175 across the board at 8.8:1 so i would say 175-185 tops

 

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

 

i usually do it on the fourth compression stroke and take that # for every cylinder....Good info tho above!

 

usually when i do this I unplug my dizzy and the butt connector for the injectors, without being at full throttle...amirite??

 

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
