Re: Engine Dyno Vs. Chassis Dyno
Relative to either dyno, a track:
1) has changes in weather, temperature, humidity, etc. over the course of a day/evening
2) often has inconsistent prep work (ie - how much sticky stuff is down)
3) relies on the driver's ability to launch the car, change gears, etc
4) will give different MPH and ET for the same car based on how much fuel, water, driver weight, etc. is in/on the car at a given time
The track is more fun.....but the science, analysis, etc is all done better on a dyno.
The butt dyno is one of the worst measurements.....especially for the Kardashians.
It is exponentially easier to tune a carb and a distributor on a chasis dyno where everything that I've mentioned in points 1-4 has been eliminated.
For example, it's MUCH faster to change jets and other carb parts when actually getting an AFR reading from a computer.....then trying to figure why Pass A was better than Pass B, which wasn't as good as Pass C.
Money spent on a chasis dyno is some of the best money you'll ever spend in this sport/hobby....and a massive time saver.
