Re: Variance in Dynos????
why does everyone say there is something fish with the dyno? cant there be anything fish with your car???
anyway, i will reapeat myself one more time as i have many times before ,,,,
Dynos are tuning tools, not accurate measuring tools, too many factors play an important role determing the readout on the spot, anything from tyres, tyres pressure, tyre tempurature, air pressure, air density, humidity, etc, etc
the only possible way to get a constant and accurate reading is on an engine dyno with controled nevironmental conditions (see NIZPROs engine dyno, where air feed, cooling, intercooling, etc etc is computer controlled).
In addition, to run on a dyno day, it cam mostly be said that you can compare the figures with other cars run on the same day, as most environmental conditions are reasomably identical for all cars.
So please ppl dont kill yourself over powerfigures and be all disappointed if you run a figure way lower than promised or expected, by the end of the day it all comes down to how you can drive/race your car on the track or drag strip.
For your info, i have run a 139kW figure on a DynoDynamics and only days later 106kW on a Dynolog ... oh and my current best 1/4mile time is somewhere between 15.2 and 15.0 ... again go figure
