Just wanted to know if installing an underdrive pulley on the alternator will be ok since I've heard that an UDP on the crank is bad because it removes the harmonic balancer? What kind of gains will I see with the alternator pulley and is it worth it? Thanks.
I am enjoying thoroughly my 2003 SVT Focus but here in So Cal, as you all know, we are held hostage by CARB. What street-legal mods are you all running? I just don't see the point in adding some cool mods that are illegal and then having the man make you take them off. Any suggestions? Cliff
