Question Has anyone tested 0-60 times with only FWD??

I know the auto trannies have a fuse to make them FWD... has anyone ever experimented with times?

Im just curious to see how much (if any) the AWD slows the car down.

Unless you plan on buying a new transmission, DON'T DO THIS.

There is a reason the FWD is activated by popping the hood and moving a fuse, and not just an inside switch.

slows down, ummm no......awd would have little to no wheelspin and therefor would accelerate faster!!! fwd would spin and loose traction which = slower acceleration

spt_impreza,

Your right about traction/wheelspin and AWD. But generally speaking... some performance WILL be loss with AWD due to friction in the drivetrain. With dry conditions (like on a track) and 2 identical cars (1 w/ FWD and 1w/ AWD) the FWD should be faster.

Question

I thought that the autos run in Front wheel drive most of the time,and switch to AWD when needed?

Well the car's still AWD. It just transfers 90% of the power being sent to the front wheels. So it behaves like a FWD. So the car doesn't switch between being AWD and FWD, it only switches the amount of power being sent.

But when you use the fuse to make it FWD you're electronically forcing it to only use the front wheels, which it wasn't meant to do.

Does anybody know if the VC would still heat up in this mode? Being that two wheels are getting all the power?

If im not mistaken the autos use a 90/10 split and the manuals a 50/50.

It is definatly not good to use your fwd fuse, it is only there if you have to tow your car.

Its all in the owners manual.

I believe that the SVX auto tranny is 50/50 at rest, and shifts to 90/10 upon reaching cruising speed- and using the FWD only mode may overstress something if pushed hard.

The owners manual says bad things will happen if you run the car in FWD so I am not going to try it. Either way(FWD/AWD) the automatic will still be slower than the manual.

I think that it wouldn't give you much of an advantage because the AWD system is still there, it still has greater drivetrain mass. Just not spinning the rears. So its basically lugging around an AWD system for nothing.
