Well mine's an 07 BWA... so I'll keep an eye on it!
I think you'll reach the limits of front wheel drive before you reach the limits of the internals with this one. TTE420, or bigger?
I'm sure yours will be fine, my car was always very loud and I still noticed for sure when the chain started so to be honest you get a fair bit of pretty obvious warning anyways
Yeah TTE420 is about the 'safe' limit when pushing it hard. I though about it but its too much and as you say for FWD it would be such a bitch without a diff that I couldn't use the extra power anyways.
I'll see how this setup does on the dyno and road but should be getting R-Tech switchable mapping (if they ever get back to me and my ECU is suitable) so will have a sensible 'ish' road map/ track map and a dick head map
