Bit of a debate going on in the Jaguar area about dyno numbers, Jaguars claimed BHP and the discrepancy between the two. Not easy to solve without an engine dyno. But I did wonder - there must be lots of PHers who have dynoed their car whilst it has still been standard so there must be some useful info about how accurate rolling road dynos are.

If you have dynoed your standard car ( has to be standard since only then do we know the manufacturers claimed number) what was the result and what did the manufacturer claim?

we've been through all the above guys - what we want now is data. dyno bhp figure vs manufacturer claimed number on a standard car. Anyone got any?
