how many miles will an S trim go???

How many mile can you put on a street driven S trim at 10 psi before it will be needing to be rebuilt?
thanks

at 10 psi the thing will live forever,the one on my 94 cobra is 3 years old and no problems,but I use amsoil engine oil in all my cars,the better the oil the longer those bearings will last.

I ran an "A" & "S" trim both over 100k w/no probs....

Should last a long time as long as you keep the oil clean :)

I had an A-Trim that went over 125K miles. I overspun it with a smaller pulley. I sold it and the guy that bought it still uses it. No oil leaks and it's never been rebuilt.
