Has anyone noticed any difference in fuel consumption after installing aftermarket LSD?

 

anyone??

 

has absolutly nothing to do with Fuel Consumption...

Does not change the amount of RPMs the motor has to make to sping the wheels..

nor does it require any more power needed to spin the rear wheels...

 

yes, i know that but fuel consumption is not only rpm or throttle dependant.. the drive train efficiency takes a big part of it as well..

i was thinking, depending on how 'efficient' the clutch type lsd is probably has some effect on fuel consumption because it will create more drag to rear wheel at low speed turns and etc? open diff will just transfer the torque to whichever wheel that gets or loses traction, whereas clutch type lsds (including torsen) has much aggressive limit of slip which will 'drag' the torque that goes to one side to match with the other side. LSDs give better traction and all that because it can transfer the torque to the ground more efficiently, but that being efficient obviously means more 'load' to the engine through the drivetrain also.

i am thinking, since that extra 'drag' or 'load' is always there with aggressive lsds (not necessarily slowing the car down but fully transferring the power to the ground), it probably has some effect to fuel consumption?

any actual words from the users will definately clear this out.. anyone?

 

I have had the Nismo LSD for over 60,000 miles and have never seen a difference in mpg... I also have over 400 whp and still average 16-20 mpg....

 

No difference. When you let off the throttle while rolling in gear, you use 0 amount of gas.

 

it does no effect the amount of force needed to turn the rear wheels...

it just distributes the power to both equally going straight or turning...

if a gear ratio was changed then there will be a differance...
