It depends on:-

1) who calibrated the Dyno
2) How they calibrated the dyno
3) What the weather conditions were
4) etc.

Secondly, if the performance at 1000 rpm below that max power was 5bhp, it would be MUCH better than if the perfomance was 1bhp at 1000 rpm below max power. You haven't told us that most impoortant part which is the SPREAD of the power curve. A peaky power curve is useless on our tracks.... but a WIDE power curve peaking at 7.1 sounds pretty good.

What I am saying is that there really is NOT much point in just relying on a single item of data from a Dyno!

For fun, use your rev-counter's datalogging to see what percentage of the lap you actually HIT those revs where the Dyno showed 7.1bhp. You'll be lucky if it's 5% of the lap!
