Dyno plots

[Turbo T]

I was just looking as some Supra Dyno plots. Now we all know that many over read the BHP figure significantly, the torque figures look realistic on some. Is it generally harder for the operators or dyno's to over read the torque?

you can alter Dyno operating perameters to give an inflated figure

I assume an easy way to fudge BHP is by using a lower gear, but would be good to get Charlie's input.

We had a Supra on a dyno which was making huge power, more than the turbo could flow . The operator called Australia where the dyno was made, they told him to use a different ramp rate, hey presto, a much more realistic figure appeared.

I was just trying to see if the torque was harder to fudge then I would start ignoring the BHP and look at the torque figure when looking a sheets.

Thanks Charlie. Out of interest, what perameters if any, do you need to change between say a FWD NA motor to a 4wd Turbo, and 2wd Turbo.
