Speedway Motors mini alternators are a great addition to your engine, whether it’s for the great look or the reliable high-amperage output. This alternator produces max 90 amps at max rpm (68 amps at turn on 1600 RPM), which will generally meet the demand of a hot rod or race application. Its compact and lightweight design allows for installation in the tightest spaces. Our race alternator kit includes the V-belt pulley and bracket to complete your install.

The alternator bracket will attach to either the driver or passenger side of the engine using the two bolts attaching the water pump. In most cases, this drive system will not interfere with existing setups.

The water pump pulley will bolt onto your existing water pump pulley.

This combination utilizes a 54.5" effective length v-belt (such as Gates 7545 - included in the kit).
