I thought a drivetrain loss was always 15 percent but this guy seems to think differntly. Whose right me or him?

I dont know the techinal aspects of that, but you seem to have cut him up real bad
There is no way that all drivetrains produce the same percentage of loss. Most drivetrains are different from each other. He is certainly right. There are so many factors that can affect the loss of power going through the drivetrain.

I know different setups have different setups losses but most are around 15 percent. But also some drivetrains to sports cars are very simmilar.
Yea i've read somewhere between 15-20% is the average drivetrain loss too. It just confused me how you used the word "always", rather than saying "most often around", or maybe even just "always around".
Drivetrains lose power because they too take power to turn. So heavier drivetrains will lose more power, for example ones made with heavier materials or drivetrain systems that are 4wd.
I don't believe that the guy is 100% right now that i think about it. Although i also don't think that you can assign a percent loss to a drivetrain and use that to calculate how much power is lost after you add horsepower to the engine. He's right in saying that if you double the horsepower of your car you aren't automatically going to lose twice as much horsepower through the drivetrain. But I also don't think the hp loss before and after the hp upgrade will stay the same.
FWD is typically 10-15%.
RWD is typically 18-25%.
AWD is typically 20-30%.
It depends on the weight and number of the parts involved in the drivetrain.
Automatic (torque converter) transmissions usually sap up more power than conventional manual transmissions too.
^ Absolutely. Forgot to add that to my post.
i heard the reason the corvette z06 could beat the viper, f430 and 911 turbo in terms of speed was because how it didn't lose much power through the drivetrain
I knew different setups robbed more horse but his post didnt een make sense. Ah Nissan 350Z owenrs theyll never have to worry about horse power.

Weight and more dyno proven horse have nothing to do with it.:rolleyes:
Nothing to to do with it being a lightweight, powerful track car for the road then?

Does that mean a bugatti veyron is losing 300 hp.
Thats a ridiculous amount, is the loss the same percentage for all engines or is it less as you increase in hp?
drivetrain loss as he said is partially non-percentage, a 1000 hp car wont have the same percentage loss on a 5 hp car if they have the same transmission. but in the normal range, ie in the 100 to 1500 range , all systems tend to have about 15% loss

I've yet to see a dyno, but it's very possible it's only putting down ~750whp.

Well it has to have a well engineered drive train for that much power, so somehow I don't think its going to lose 300hp. :cool:
