UD Pulley M6 Problems?

**sdbrown84** · 05-12-2006, 09:10 AM

I am currently working on a full bolt-on project SS that will have an LS6 intake, QTP Headers, Custom-Y, and a Tune put on the car within the next month.

However I am considering a UD pulley as well.

My question is to people with an M6 car. Are there any drawbacks such as a loss of powersteering or dim lights with the car at idle and the AC running?

Any cooling problems?

Any other input would be great as well. Thanks!

I've had mine for a while now. I didn't notice a difference in anything.

Same here.

I have a a4 with a ud pulley and have experienced no problems. I only have 13 volts when the car is completely warm, lights on, fans on high, and radio on. Turning off the stereo would probably fix this problem though

Zero problems here, 4K on the clock.

For the most part there are no drawbacks to an underdrive pulley on an M6. My lights are SLIGHTLY dimmer and my steering is SLIGHTLY more difficult, but I'd bet most people wouldn't even notice the difference. It's nearly imperceptable. I wouldn't sweat it one bit.
