Chassis Dyno Information / Guide / Myths!

I suppose if you want a fair comparison you need to keep going back to the same operator at the same dyno. The UK is never going to go to talking about WHP figures as there is too many willy wavers about.

The problem is WHP figures are also just as variable as flywheel figures and aren't an accurate report of what actually does get to the road either. As always, a dyno is a tool for tuning, not really for comparisons between setups, even though it gives you a rough idea.

What Ripp said ^^

The WHP are also affected by things like roller type / tyre pressures / type of tyres and temperatures etcetc, obviously as this is the raw reading after all  said things are removed.

There is no reading you can take from one dyno, to another and directly compare, not with any form of accuracy anyway, Its a very useful tuning tool, which can also give you a rough idea of your power output, but rough at best imho.
