Ok I finally got the new crank pulley back from Vortech. Ok here is my problem. I gte it on and everything running. I take it down the road. Note: when I first drove my car home when it broke the harmonic balancer I heard a tocking noise like an exhaust leak but I was running the factory crank pulley( no SC) so I was limping it home. Anyway it sounded like an exhaust leak at low rpms ( I never took it above 3k rpms) so the noise wasnt that loud.
Ok now here is the problem lol. I put the SC belt on and I tightened it but I didnt tighten it REALLLL tight like I usually do. I am scared I am going to break ANOTHER HB ( 3rd one) and I crank the car. I look at the crank pulley and it has a slight wobble to it. Before it did not have this. Ok so I drive the car a lap normal. Everything seems fine. So I nail it and feels pretty good (considering it is hot as hell where I live and I have no intercooler) and as the rpms start to climb I heard that ticking and sounds like rattling now and gets louder as the RPMS climbs. I take it to 5K and it made 12 pounds of boost. The problem with that is that it use to make 15 pounds of boost at 5500 rpms. I am sure it might make 13 or so at the rpms. I noticed though that the boost dropped from like 12 to 10 once I got to 5K so thats why I let out. So me sitting here typing this and looking at it I would think that the belt is slipping causing the boost to drop. but I am wondering if that is why the boost wont climb as high. Anyway that is one problem that I am not so much worried about. My 2 biggest worries is that clacking and that crank pulley wobbling. I checked for exhaust leaks and couldnt find any so now I dont know what to do. I will post some videos up in a few seconds if I can so you guys can see the pulley and maybe hear the rattling. I am not sure if you will be able to hear the rattling going down the road on camera though. Sorry so long but can you guys maybe shed some light on the situation and help thanks...
