Anyone know DA53 RKO?

[Samos52]

Bought the above 172 cup 6 months ago and was wondering if anyone knew who owned it previously as would like to know what mods it has in the engine as it ran 172.5bhp on a dyno the other week.

If it looks standard under the bonnet it might just a 'strong' engine. 172 engine outputs vary from the factory and at this time in their lives servicing and other factors will also come into it.
This is all assuming the RR is calibrated well. But thats another argument for CS to have.

If your dubious try another local RR or just post your RR results and be smug.
