Hi Mate
I have been planning on drawing some up to take an 8rib serpentine belt.
Will also make under driven units for high rev applications. I just have not had time to draw them at present. As I blew up my second 1uz, and haven’t even driven the track car yet!!!! So I have a bit of work on her. Will have it done soon, I also plan on machining up some eye candy parts as well. Just been busy!
