i have no idea what brand mine are, they were on the car when i bought it but i have bad charging and cooling problems, if i went with a better brand cuz i beleive they are real cheap'os would this help out any id like to know how your bbk's treat you?
in my experience with pulleys that I've owned (Summit, BBK, MAC) they are all dead even the same. if you were to put them next to each other or dyno them there wou;d be no differences. I think you can get the summit brand for like 80 bucks thats the one I'd get.
