And you know this from experience in running one on your car? I have ran a 65 for 4 yrs now...on the same belt without a PSK, although the roadster is getting one. I have over 2500 miles on the 62 without any issues so far. Not even belt dust with a PSK... We have done the 1/2 mile event with it and several hard runs while dialing in the tune. On the other note, of belt raps. Robs is the only one I really trusted to hold up under the stress of what I do. I liked tighed1's cheap belt rap and have the parts to do it, but after seeing the stress put on that 1 grade 8 bolt, I decided to go with Rob's set up. Just my take on it. But, I haven't had any belt issues at all. I keep spares around but haven't had to use them.
