Ya, i just warmed the car up, went and got a fresh tank of gas.
Came back and tested all the cyls..


my needle goes to 300psi in like 7 cranks, whereas the general rule of tumb is 10~12 rotations of the car.. lol..

i'm pretty sure its maxing on this puppy lol I guess thats a good thing right?

307.46 psi is baller. You just missed by a hair. Time to give up.

dont they make diesel testers that go higher?

do the comp test on the vtec lobe. bet it doesnt go over 300 then

Its not a true reading since your still on the small cam lobe which have really early IVC angles, activate vtec lobes and you will see a 60 plus psi drop in cranking compression. My motor currently pumps over 300psi on the 3rd pump, a nonvtec motor pumping 300 is a ton different than a vtec motor.

This is my third D series setup to pump 300 :) I like my stump pullers
