Here is a a brief summary of how a Dyno works why we use a Dyno not just for power runs but as a diagnostics tool, also we show a bit of live data logging.
So, does the dyno display the wheel figures or the wheel numbers corrected for frictional losses. We often hear people saying "my car on the dyno showed X amount of torque at the wheels", thus assuming that the engine actually produces higher numbers. So, ultimately, does the dyno display the "wheel torque" or the "engine torque".
It's measured at the wheels, and due to losses that occur from the drive-line, you can assume your engine makes more power. This type of dyno in the video shows HP at the wheels, while an engine dyno would show true engine power.
a dyno doesnt measure "wtq" numbers. its basing it off of actual wheel hp numbers and given the rpm of the motor, tells you what would be created in tq to produce the whp numbers. This would be the "wtq" outputted at the crank to tire after losses since it cant record non-loss output. This "wtq" is what is outputted at the crank, after the driveloss. but the actual crank tq would be higher.
Than if I get it right you can measure the power coming from the engine to the wheel on computer but in real life that power couldn't be transmitted into the car movement. It's some laboratory science but it doesn't really matters. The wheels would burning and no movement. Maybe it worth to know what power your car have if you want to tow a caravan. Can you measure the BHP if you go up to the highest gear than turn on the cruise control for 60mph? I'm dying to know what is the amount of power needed for driving a car at 60mph on motorway. Can you help?
Hi, what does it mean if on a dyno run of my E46 M3, it was found that the car has drag power almost 31 percent? It makes 333 PS at the flywheel but only 217 to the wheels.
Joseph Bentley hi there what difference does that make? We keep the bonnet open to help the heat escape from the engine bay, bonnet up or down has zero consequence to the power output of a car, cheers
That explains it perfectly, I always wondered how driveline losses were calculated, and that makes perfect sense.
Underrated video, thanks for the info.
thanks alot for the explanation ... needed it desperately for my project on chassis dynamo meter ... beautiful explanation with data explanation tooo
will u explain this in hindi, urdu or english in text please
Thanks it was very informative I hope your channel sky rockets 🚀🚀
Great video. Thanks chaps
The video i didnt know I needed to see
Great video, could you turn up the volume a lot?
Great video but just to be clear, are you claiming that a vehicle's driveline losses can also be calculated in addition to the wheel hp?
did u ever measure how many dB did you kill with those sound absorbers?

Did you install a brake in the transmission by chance and forgot to disengage it? Lol
dynamo is measure the power,torque and diagnosis them please brief it or explain it?
Brilliant
Thank you
Good video. Outro is a little loud
Tuned diesel bmw 18d and 20d has to be 50% of every tuner business income 😂
Any diesel sedan or hatch really, loads of 4th and 5th gen TDI golfs as well lol
Is that a portable dyno? I want to buy one
jcanbrownboy yes it’s a V-tech Dyno with the mobile kit, cheers
I bet Race concepts ? Been here!
While the explanation was informative. You explained the functions and how to use a dyno, not how it works. Maybe change the title. Thanks anyway.
😴😴😴😴😪😪😪😌😪
Should be done with hood down. Unless you somehow drive with the hood up.
