trushot, I' d be interested in what your chrono tests came up with. I don' t have a chrono, but actually got the same idea that the turbos may have increased the speed slightly. As far as niose however, mine make a lot of noise. I am having some trouble now with the fins making contact with the cable. I thought I had the contact problems ironed out, but I have a slight problem. I ordered a Timberline cable slide which I think will pull the cable closer to the slide, which will give me the clearence that I need. My simms teflon slide is nice, but it sticks out a bit too far for my liking.
