compression
for anyone interested here is a good how to on a compression check here is a good link
http://www.c-speedracing.com/howto/c...t/comptest.php
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.

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
