Compression test results :)

I changer my plugs today and gapped them to .030 from .035, because I have a high end miss. I also did a full compression test. My motor has ~50,600 miles on it now and I have been putting allot of highway miles on it over the past 4 months. I use redline 10w30 I wouldnt say that I abuse my motor frequently, but ocasionally I do beat the crap out of it and I aint exactlly scared ob boost. My previous results from ~25,000 miles in April 02' were 215 low cylinder and 222 high cylinder, a 7psi difference. This time I had a low cylinder of 204 and a high cylinder of 208, a 4psi difference. I lost 11psi but I am still way above the factory standard of 185psi, at this rate I should hit factory standard by 100k. So tha motor is wearing a bit but it is wearing evenly. Plugs looked good, maybe a couple specs up on the ceramic insulator, but the ground straps were all discolored nicely. I very am happy mith my VQ. Now to push it a little more!!!
