If you go with the 'race only' kit you may may experience a slight drop in voltage at idle. No big deal and small sacrifice for the performance increase.

 

What about if I'm driving around with all of my accessories on? Can the alternator handle that with the new pulley?

 

just get the lower pulley and not the altpulley that comes with it. You wont have any charging issues from just doing the lower pulley(its the main one u need anyway). Those that do the alternator pulley have a drop on voltage at lights commonly found in A4's. M6's dont see that drop as bad

 

has anyone had any balancing issues with their Pulleys?

 

I'd like to do this mod I'm just wondering what effects it would have.

Getting this pulley done correctly has been the biggest pain in the butt that i have had to deal with my car so far.

It is coming off a fourth time this next week to be sold, but just crank it down with the original crank bolt till it won't go on anymore, then out the new bolt in and torque it down, it really is that simple.

 

It is highly unusual to get an unbalanced pulley from ASP as VHG says he did. The crank pulley MUST be in alignment with the other pulleys that it drives AND the belt MUST be under tension. This applies in any pulley/belt system regardless of whether you use an ASP pulley or not. If alignment is a problem you need to visually inspect your pulleys. You can also use a straight edge to check for alignment. Use a piece of steel flat stock to check it. You should also have checked the relationship between the factor crank pulley hub boss and the crank snout before the factory crank pulley was removed. Did you do this? This is the relationship you must initially start with to maintain proper pulley alignment. Charging with ASP is NOT a problem unless you spend more time idling than actual driving or you have a 1000 WATT sound system.

 

Since i put my asp underdrive crank pulley on this last weekend i love it. At night the voltage stays around 12-13 volts but goes back up when u start accelrating and also love it when u drop in 2nd gear and my car starts going sideways. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

That can happen if you don't lubricate the OD and ID of the hub like the instructions indicate. You can gall the aluminum ID of the pulley without the proper lubricant which can cause it to be out of balance and/or wobble.

 

I had an M6 LT1 car previously that responded very well to underdrives/cold air kit im ready for the pulley on my `02 WS6 but is there any alternative to the ASP piece 25% reduction seems like alot i cant seem to find an underdrive set from anyone else like March or BBK

 

Another advantage to the underdrive is that it slows all the accessories, including the idler, and protects them from high RPM wear. I was reading that the rev limit on the LS1 is there more to protect the accessories, that the engine itself can rev higher. So if you take her up through the RPM range from time to time, this is a good thing to have. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
