For those of you who may be interested in bypassing your power steering, I have attached the following images to show you the bolt that you need to grind down. You only have to grind it a little to ensure that the belt, which will take a new route, does not come close to it during operation.

I have had this for over a month now and at first was a little hesistant on keeping it this way. It does take a considerable amount more at parking lot speeds to turn the vehicle. However, once you get used to it, the feel at speed is fantastic. Having driven a Z with power steering since being used to one without, I can tell you that I will more than likely never put it back on.

This is not for a weak individual or one who likes driving around with one hand only all the time.

 

 

so what exactly does this help with? to make steering harder?

doesnt this release more power or something as well?

 

actually i don't think it helps anything at all, except build your forearm muscles. but it's your car, have fun

 

Make sure not to overtighten the belt or you will kill your alternator.

 

if you disable VDC there is no lag between turning the wheel and the wheels turning... the steering wheel becomes more responsive...

and with the UR Pulley steering is a little harder with the power steering pump underdriven...

disabling vdc not by pressing the button...

 

Interesting, I've NEVER noticed VDC to impacting anything steering related.

Where as you getting this from.

 

The UR pulley plus the bypass of the power steering, puts less drag on the motor. This is one less accessory. All though not a huge gain every thing counts. I know I felt the power gain in take off acceleration.

 

Its a trick some drag racers use. Yes it improves acceleration.

 

have you fully disabled VDC yet to feel? not just pressing the button...

but instantly you feel the whole care is more responsive... even slight movements of the steering wheel...

for "legal reason" etc I cant post how to do it...

 

Might as well remove the belt driving the air conditioning too.

 

I thought about it, but it's just too hot at times in Texas.

 

vdc disable involves pulling out the fuse right?

 

Actually... yes... many times.

You can throw the car into a "donut" and it will do it... in turn illuminating ALL the guage lights.

OR, do like Mike Edens and run a bypass switch... Only thing different I would notice, would be during an autox where the break distro systems would not be as intrusive.

Still... no impact on steering.

 

I took a look at my pulleys today but did not find where I can get the belts lose to remove them. Maybe I need to look from the bottom of the car?

Anyone know how to fully disable the VDC?

 

Wait, what kind of acceleration gains are we talking about here?

 

The belt tensioner is the flat (non-ribbed) pulley between the alternator and crank pulleys. The tensioner bolt is vertical from the bottom of the car. (should be 10mm or 13mm). You will need to remove the undertray to access this.

To disable VDC/EBD/TC unplug the "yaw" sensor. This is the small blace Bosch sensor under the center console, just in front of the e-brake.

 

I found a fuse in the fuse box near the battery, it's a pink-ish red fuse with #50, and it say's VDC on the case?

 

I guess I'm not understanding how any amount of traction control of any sort could ever affect how quickly the steering responds. Since the Z's steering ratio is not variable and is achieved by mechanical gearing, the ratio and resonse time can never be electronical altered. If you move the steering wheel, I would've thought the front wheels would move at exactly the same instant, every time.

Perhaps VDC is just messing with the power assistance, and that's giving the feeling of altered response? Power steering assistance is variable (typically just depending on vehicle speed, right?), so I can imagine VDC doing something goofy with it for some reason. Or maybe that's what you mean, and we're on the same page.

 

no it is not a fuse that is pulled anywhere near the battery or fuse box...

but you will have the VDC / SLIP light on perminantly from the moment you turn on the car...
