I’m not noticing slippage in the datalog but I am noticing belt dust. I have used dressing and it helped but didn’t seem to help long term. I also may get a machined snout and smaller pulley and might as well take advantage of that custom crank pulleyThis was my next step, something to note is I did not have belt slippage issues... I also applied belt dressing liberally
I don’t disagree at all. I have all these ideas in my head. It’s nothing I’m doing right away. Winter project will definitely be the inlet and maybe the snout and pulley.A smaller pulley may make the issue worse but going to 8 rib may offset that. Imo I would redo the inlet tract first, if you have a way to monitor vacuum in the inlet side we can see how much of a restriction the current setup is.
you may be right, there is a lot of belt dust though. I didnt post a pic but i'm actually using a bigger idler to the left of the blower and it wraps even more. The blower pulley and crank are for an 8 rib belt so i might as well get the rest of the pulleys and run an 8 rib. If anything it wont look like I'm running the wrong belt and it certainly wont hurt.I looked back a bunch of pages to find pics, that looks like a lot of belt wrap.
I'd be kinda surprised if it was slipping.
I am running a Gates belt for superchargers. Not the green belt though. I think the 8 rib will solve any issue I'm having if its actually slipping. I don't mind the work and the pulleys were less than $100 and it'll look more complete with the whole pulley being utilized.Well , can't get much better wrap then that.
What about trying a different type of belt?
When I had my various supercharger set-ups I remember people having good
luck with the Gates fleet runner belts.
