Are these all measured on the same dyno ?
Cause what's weird is that dyno 3 has a lot more hp at the wheels then dyno 2 and yet the crank hp is only a minor difference.
And dyno 2 has about 20% loss between engine and wheels and dyno 3 has about 11% loss between engine and wheels.Dyno3 should have a higher crank hp with those wheel hp's .

dyno run 1 war with winter tyres 185mm
dyno run 2 was with summer tyres 195mm

all on the same dyno, but between 2 und 3 is more than one year and in this time the dyno was 1 time demaged!

and whan i have the 3rd run, my engin mounts were demages and also the dyno has much vibration

so i wil make dyno run 3 again with new engin mounts, bevore start the mini me

PS.: i dont give much on the theory power, because ist is only theory and so i look only on the WHP

Hey nice to see your dyno's! (For the others, we had some email conversation before).

Any idea about AFR? Numbers seem a bit low to me actually... especially the torque specs (if they are flywheel estimates). I would recommend a test without the cold air, just put a 'normal' 3 inch open air tube on it if you can. The dip around 5500 rpm worries me a bit, might be bad acoustics due to unpleasant timing of the pressure pulses, just a bit guessing.
