Using a reduction gear is like using a lever to lift a heavy object. There is some mechanical advantage which is proportional to the amount the gearing is reduced. ie. 1st gear gives huge torque figures compared to 2nd and third respectively. That is why we dont all take off in 5th gear, the torque is not there.
4th gear in most cars is as close to 1:1 as possible, which gives the most accurate absolute result.
Don't forget HP figures are merely a straight calculation from the torque recorded by the dyno, a multiplication of torque over the real figure will result in inflated hp figures.
Lastly , this is all only relevant if you use the dyno as a bragging tool or development tool. Trevor has over the course of the development of his car, dyno tested the car in the same gear and conditions each time so any gain by each mod is accurately reflected by the dyno.
I'm not bagging Trevor, I just find the science of Dyno results to be interesting, widely misunderstood, and generally misleading.
How many zoom articles have you read, where the 12 second tidy street car, makes 400 rwkw, but the supplied dyno chart only goes from 40 - 110 km/h.
A detail often over looked when we try to compare our own cars (maybe not 400rwkw !) to some of these mildly modded imports etc, that make power figures we cant go near with the same mods !!
