Just sold my 8IGHT that had over 30+ Gallons (2.5 years old) and replaced more parts do to wear then I could ever recall. (Probably had 2 complete buggy worth of rebuilds) But very little do to breakage though. Good buggy, but wore out parts like crazy.
I have over 2.5 Gallons on my X-Ray 808 now, and haven't broken a single part, or wore out a single part. (Beside clutch parts) Its still just a tight ( But free) as the day I built it. I'm extremely happy with my 808......
