Hi Denton,
I think they are just incorrect, it seems to have been mapped against KPH. When I run a calculator on the speed, diff ratio and tyre size in top gear then I get 3900 at 150KPH and 2800 at 116KPH which are the peak torque and HP measurements.
So I ignored the rev numbers but was concerned about the HP numbers- assuming they are correct. Wondering if slightly retarded timnig would have a big impact?
Cheers
Sean
