Bill-
No idea how many R's are out there. I see a few come through the dealer where I work- maybe 2% of the wagons are R models, 5% are V70AWD, 20% are XC, with a scattering of S70AWD. We tend to have more AWD cars here in Denver, so I don't think other parts of the country see as many. I bought my car used in November and although it ran ok, I felt that something was not quite right. The most obvious symptom was after the 1-2 shift at WOT, it had a substantial lag until the power came back on. No codes, no misfire, just a feeling that there should be more power on acceleration. Some other R's I drove ran about the same, some were so much more powerful that I suspected they had been 'chipped' even though nobody has released upgrades for the ME 7.0 yet. One slow day at work, I decided to verify the cam timing. I found the exhaust cam to be retarded from the desired factory spec. When I started the car after re-assembly, the engine sounded different. Much improved power, negligible lag on the 1-2 shift, better response at any acceleration. The change was enough even my wife noticed the improvement. This is a tedious job that takes Volvo special tools to lock the crank and cams in position. My car was the first variable cam engine I have set up and took over 4 hours to complete. Now I feel my car is as quick and strong as any I have driven, so I'm happy with the performance.(for the time being)
