Don't know how dynos work downunder, but on this side of the pond they result in a power/tq graph vs rpm which illustrates power curve, peaks, spikes, etc. Many of us also log other various parameters when doing dyno pulls like AFR/Lambda, EGTs, etc.
If you don't start your pull at 2.5k rpm to mask just how useless your big turbo is on a DD, you can easily see lag/spool.
As previously stated, I'm interested in seeing the difference between how the different snails react and shift the area under the curve instead of some peak output or whatever gets most people around here hard AF.
