Do you know where temperature for SAE dyno correction is measured? Is it ambient temperature or they put some sensor into intake to measure the air directly sucked by engine?

Here http://wahiduddin.net/calc/calc_cf.htm they say: "The air temperature should ideally be the temperature of the air that is going into your engine." So how is it on the real dyno?

And another question: When I get the Dyno Correction Factor (Cf), what should I multiply this by? Should I multiply both torque and power by this one Cf factor? Or multiply only torque and then recalculate HP? Or vice versa?

Thanks.

 

what dyno where u on
