i checked mine and got 205 on the first 210 on the 2nd 205 on the 3rd and 210 on the 4th. But each one bled off about 20 psi right after the last crank.....is this normal?
Also, on the 1st engine crank it was about 90, then 150 on the 2nd, then 180 on the 3rd...and kept building to the 5th....is this ok?
This is on a supercharged civic si with 40000 miles on the motor, and the supercharger has been on for 20000.

 

you like that link? You are supposed to crank until it stops.....it will spike a bit but where the needle stays is where you are supposed to read. btw, good compression numbers. right where they are supposed to be

I only cranked it 5 times.....i guess i should have tried more.
I still need to figure out where my boost is going though
