Title: Dropping driveshaft for dyno?
Post by: shoslow on January 31, 2014, 11:32:06 AM
I've seen it done on numerous vehicles, but have never done it personally. I haven't done much studying on the taurus' drivetrain, but I know it's not your typical awd setup. Has anyone dried this?

My relatively ignorant thoughts would be that it could result in problems related to traction control and that it was actually done because the dynos in question don't have AWD capability. 

I would question the validity of the reading for WHP since you won't drive the car without the drivetrain intact.

The main reason would be because it is not an awd dyno, yes. I figured most here probably haven't done it, but I've seen it done on trucks and older skylines, and had heard it was necessary on the newer skyline's on some of the more basic awd dyno's because they were grenading parts.

Trucks are way different in the sense that there drive train is primarily 2WD Rear wheels, and on command 4WD. and the GTR awd is way more advanced than ours.

Interested to see how this works out

Exactly. I've seen it done on older skylines. Have heard of it being done on the newer ones for drivetrain reasons.

The computer would never tolerate this for one.

What about e-brake on traction control off? E-brake disengages rear drivetrain.

Hadn't heard that... Still, if you want a dyno for an AWD... I'd say do it on an AWD dyno

Just read that the other day. Makes sense since the rear is electronically controlled. I engaged the parking brake one click and brought up the AWD power meter and power braked it a little and it showed all power going to the front with none to the rear. It's almost as if ford wants to do smokey front wheel drive burn outs.  :burnout:

I'm intrigued... Where can I read about it?  Is it unique to the XSport .....like the sand mode?

Can't remember now. I wanna say somewhere over on the SHO forums. I was reading up on the AWD and somebody mentioned it there. I'll give it a better test tomorrow.

Don't do it, it won't work and you will have major problems.
