Well Bob i guess i will have to take your word.Hard coat anodized or Carbide coated.Maybe a steel sleeve.We have tested that bell with good results ,But they dont last that long ,,Be great for sprint car ,,,,,:thumbsup:
Yes Brent I know.I just used it for a topic.To see If there was a possiblity.For future Use.Just in case someone doesn't know this, clutch bells are an Impact Part and, to the best of my knowledge, no aluminum ones have been approved yet.
Thanks Bill,This a is another interesting topic . I played with this my self (aluminum clutch bells ) but very high maintenance with very little or no benefit.The Qsac rules cover impact parts on page 21, Ed
Hi Brent"1/4 Scale" is right. Less rotating weight is the supposed advantage but I did this with clutch shoes and couldn't find the benefit. The shoes and brake tear up the aluminum in short order then aluminum eats the shoe and brake material. I haven't seen one used with a good hard coat so I don't know if that would work. But why go though all the expense for no appreciable benefit.
Brent i hope you did not think i was picking on you?I was agreeing with you.No Ed I've never tried an aluminum bell but I've seen it used and it was not pretty. I based my information about less rotating weight using lightened and aluminum shoes.
The other reason for playing with the shoes, besides rotating weight, was to see if the clutch could be made to slip, muiltipling the torque coming out of the corners. The results were that there is a very fine line between slipping out of the corners and not engaging at all! The only way I can see this working is with an externally adjustable clutch which, per QSAC rules, is not allowed. I hope posting this saves somebody a lot of work.
