Chassis dynamometer?

I was thinking maybe instead of the Dyno than measures power and torque from the flywheel I was thinking after the Car Designer is complete and we are completely able to build an engine and put it in a car there should be a Dyno that measures power and torque from the wheels of the car.

Ehh, not really worth the effort when all it would tell you is the same thing the engine dyno told you minus whatever percentage drivetrain loss that you’ll have the stats for anyway.

there is a huge difference between flywheel power and power to the ground this way would make it better to do gearbox tuning (if you have this at all) rather than a try and fail method

Yup, and I’m saying that by expressing how much the losses are when you are picking gearboxes/diffs etc. you then don’t need a chassis dyno, which would take a few months of work on our part, all just to show how much drive train loss you have. I really don’t understand the point of it.

there is no loss in drive-train none there is only a conversion of power ie more torque at the cost of less horse power then only “loss” is power overcoming friction in the diff and drive-shaft joints and it wouldn’t be much work you just change the engine dyno animation to one with a car running and change a couple of lines in your coding to calculate the torque/horsepower ratio

Yes, there is power lost, there is plenty of friction throughout the entire drivetrain, including gearbox, Also oil drag etc in the gearbox, you can’t turn that stuff without expending energy, and depending on what kind of drive train/gearbox setup you have as much as 35 - 40% of your power (that’s about right for an Auto AWD car) turns into heat in the gearbox/diff etc.

When you say " it wouldn’t be much work" I don’t think you understand how much more complicated than it seems it is to do this kind of thing, I know it seems like “just change an animation and a bit of code” but the details of that, the polishing, the bug fixing, the UI design, all of that mean its is a few months work for a feature that adds very little gameplay mechanics to the game.

if you are so worried about how long is going to take how about you make as a install able piece that people can add if they want and don’t focus on it focus more on other updates and 35-40% percent are you crazy I’ve see cars with five hundred horsepower at the flywheel only lost five horsepower and one count them ONE nm of torque granted it was a specially designed oil injection system in the gear box with solid diff and drive shaft but still you would expect at least 10-20% if we followed what you are saying

now I know I don’t know much about coding I’m a mechanic not computer programmer my cousin is the one who makes games not me so stop treating my like a retard I know more on aerodynamic physics then you do on cars

Well, I’m afraid that doesn’t play out in all the automotive engineering textbooks we’ve been working from, and that’s the information we’re going to trust more. And I have no idea what your aerodynamics knowledge has to do with anything.

I’ve told you that we’ve decided this wouldn’t be a valuable use of our time as developers, what more answer do you want?

Actually the loss is about 5% for every gear linkage (so multiply the engine power by 0.95 for the gearbox, 0.98 for the drive shaft, 0.95 for the transfer box, 0.95 for the diff) and you get the right number, also there is no torque loss, and also torque is multiplied by the gear ration, so lets say your torque is 100 Nm, in first gear the ratio is around 3.5-4, so 100*3.5 and you get 350 Nm, multiplied by 3 (final drive ration), and you get 1050 Nm in first gear with a 100Nm engine output. These are rough estimates by which you get a quick estimation of the numbers, alto this estimate is very close to the actual numbers, they do fluctuate depending on the systems.

^Yup, that. You don’t lose torque as such as you can have torque without any components turning (and thus no friction)
