it's funny, back on page 14 some clever bloke said

let's see the photos of these pistons then tony.
and what do they look like? confirmed det. what a surprise

It is an ideal diagnostic tool, but cannot in any shape or form represent either the load or air flow achieved at 180mph! FACT!
What this means is that people who have their cars mapped on a RR must accept that det is a real risk when using the car in the real world. FACT!
what do you know about it?
you're wrong if the airflow and temperature is good, danny says so

The fan in the dyno cell was always good and the cool air drawn from outside blown straight in front of the main cooling fan..the cell was always good for that especially when in horsham...
that's alright then, no worries about temperature on that dyno then. oh hang on...
