Vortech Blower Service/Rebuild Necessary?
Hey guys
Anyone ever had their Vortech units sent in for servicing or rebuilding after hearing the "rocks in a can" noise at idle? Mine makes that sound but it runs fine so I was wondering if it needs to be serviced or not? I read this on Vortech's site: https://928motorsports.com/services/vortech_rebuild.php
And the valve cover vent was venting into the blower's impeller then into the after cooler for a long time as per standard installation so, would spraying carb cleaner in the after cooler help remove most of the muck that may have collected inside? I vented the valve cover to atmosphere with a little breather in an attempt to alleviate this issue.
Thanks.

I haven't serviced mine yet, but it does make like a surging noise at idle. It doesn't sound 100% smooth but its done it since forever so I'm having a hard time saying its already to "blender full of marbles" or if its still "thats just how they sound" these blowers aren't exactly confidence inspiring when it comes to noises haha

Yet another description of the sound. I quite like this one "coffee grinder" haha. I'm glad to know that's perfectly normal then. This would actually save me approximately $400 in servicing/rebuild that can be used elsewhere.

Yeah just about everyone freaks out when they first here it. It does sound a bit alarming to the un hip. You know when you need a rebuild by leaking seals/getting oil into the volute spitting into your TB, and or high pitch squealing/chirping sound that doesn't go away when you take some tension off the belt. Be careful not to over tighten the belt as it can prematurely wear your blower bearings. Should be able to twist the belt a minimum of 90 degree with your two fingers as a general target. Get a good belt with some belt dressing and shouldn't have a slipping problem with proper tension until you start getting down in the small -3" /3.2" sizes where hopefully by then you are experienced enough to gauge the tension properly as it gets pretty finite by then.

What belts do you prefer/recommend? I don't see myself running a smaller than 4" pulley TBH.

Gates seems to make the best belts. Apparently they have just come out with a specific supercharger belt, probably to accommodate a lot of the new American cars that are coming out with superchargers these days. But I forgot what the name of it is. Id look up the gates website and order one of those.
