Compression test results (Turbo JDM GSR)
today I did a compression test to see how healthy the motor was. I followed the directions from the C-speed site and I came up w/ 220psi across the board (give or take a hair or two) nothing within 5psi on each other. I couldn't believe it, so I tested again, same results.
C-speed sayz 5 cranks, but I noticed the more I cranked it the higher the gauge went. The numbers I used were off the 5 crank spot.
Whats the deal?

yeah compression will keep going up up to certain point, then it will stop.
Just use a base cranking for all and your good, i usually do 7-8 cranks in wich the compression press. should be pretty much at its max

I was just making sure everything was cool, 2 cranks put it at 180psi, 5 cranks brought it up to 220psi, 8 cranks looks like to would be close to 250psi.
But I guess that really doesn't matter, as long as w/ 2 cranks they were all 180psi and so on and so on.
Tell you the truth, I was just very surprised to see such good results.
