[QUOTE="WS6JJP, post: 10187029, member: 11520"] Well, today turned out to be a good day. We ended up making it to the dyno a week early. We got there in the afternoon and strapped it down waited a few min to let it cool down and the proceeded to make 4 full runs with a 15 minute break in between runs. The first run, as you can hear in the vid, we get alot of tire spin on the rollers, so the next 3 runs two of us sit in the trunk to help get traction. Anyways, the best part....after its all said and done the pulley performed flawlessly! We're still running the wrong size idler (too small) and there still was zero belt slip. It held boost across the rpm range just like it should, it only dropped about 1 lb overall, which is about normal for a twinscrew. Most of the 4 runs the car was taken up to about 6700 RPM's, plus the abuse of the road testing, i'd say this is just about ready to go. We're still going to continue putting more miles on it just to make sure. We're also going to be taking it back off the car and inspecting every piece for anything out of the ordinary.
