olie05 Posted October 24, 2005 Share Posted October 24, 2005 Let me explain my question... Everyone talks about drivetrain loss when calculating horsepower, but my question is, are the front wheels included in this calculation? The reason why I ask, is because even though they are not connected to the drivetrain by the car, they are connected to the drivetrain through the ground, and they have to rotate at the same rate as the rear wheels (in a rear wheel drive car, assuming the tires are the same OD). the inverse applies for front wheel drive cars. So, are the front wheels considered part of the drivetrain? Quote Link to comment Share on other sites More sharing options...
Guest PROJECTRB240SX Posted October 24, 2005 Share Posted October 24, 2005 I don't think its part of drivetrain loss because its not directly under power but it definately is parts of frictional losses. Quote Link to comment Share on other sites More sharing options...
Gollum Posted October 24, 2005 Share Posted October 24, 2005 It can't be calculated on a dyno, so it's even worse than drivetrain loss becuase you can't measure if you made it better or worse. I'd expect johnc to have some ingenious words of wisdom we'll all remember... Quote Link to comment Share on other sites More sharing options...
heavy85 Posted October 24, 2005 Share Posted October 24, 2005 I'ld say no and for the most part doesn't matter anyway as the power loss should be very small through the bearings. It's the gears where most of the power loss occurs in a drivetrain. Cameron Quote Link to comment Share on other sites More sharing options...
