As promised but late
my LM400 RR graph
Mine car was very first on rollers on an "EVO" RR day. He only did speed set up and only one run as it got 404bhp so he didn't bother doing ought else.
A few evos after, had silly bhp but also had low torque
. he then played with load setting on the RR and torque readings were nearer what you would expect.
My car had been experiencing some intermitant starting/missing issues, Iain traced after the RR day to a badly corroded Earth lead and bad spark plugs
Car was running at 326g/s at peak power on the RR Day but now fixed 334g/s at peak power.
