Up for sale is (1) Speedsource race pulley kit as sold through Mazdaspeed Motorsports. Intended for competition use only - deletes the AC drive pulley and the alternator will not generate sufficient voltage at the factory idle speed. The idle speed will need to be increased to around 1100 rpm to get around this if necessary.

Consists of two anodized aluminum eccentric shaft and alternator racing pulleys. The OE water pump pulley and OE belt are re-used with them. In addition to eliminaging the AC eccentric shaft pulley this kit slows the water pump and alternator down quite a bit. This in turn reduces engine load and increases response under continuous high rpm competition use. The alternator pulley has "SPEEDSOURCE" machined on the forward face.

This is a second kit I own where only the main eccentric shaft pulley has been used. The alternator pulley and eccentric shaft pulley mounting fasteners are still new/unused. I only need one pulley kit so this one is up for sale. A picture from the Motorsports archives is attached to show what the pulleys look like. An actual picture will be provided if needed. This kit has no danage or deficiency. Satisfaction that it performs as new is guaranteed by both my word and sales record on the forum.

$300 shipped in the US48. Will consider international shipping for established/known members with the shipping cost adjusted accordingly.

 

I might need this 1/2 yr later. well in the mean time, free bump. GLWS Team
