MECHMAN 250 Amp Large Case cast alternator for C5 / C6 Corvette - 13969250
The Elite series large cast case 250-amp alternator offers great amperage output and durability. Six phase technology, combined with massive twin rectifier assemblies and 12 huge diodes make these alternators totally durable for daily driving, audio and racing use. These impressive alternators produce 190+ amps at engine idle RPM and 250+ amps at cruising speeds (stock diameter crankshaft pulley) HOT RATED. This alternator is high RPM friendly while still offering plenty of output for a 2,000-2,500-watt audio system along with upgraded/extra fuel pumps and fans for aftermarket power adders. This alternator is equipped with a similar diameter pulley to the OEM diameter pulley allowing the reuse of the stock length serpentine belt (if low miles/good shape/fresh). We do recommend a new OEM belt size if your mileage is over 50k miles on your current belt and tensioner. If using in an OEM/stock replacement, no cable upgrades are needed. If you have added items that warrant the higher amperage needs, we highly recommend adding 2 gauge or larger power and ground wires. Many Corvettes experience electrical issues in near stock form so please ensure your current wiring is up to spec, secure, tight and routed away from high heat items under the hood. The starter wire and fan connector are known areas of concern and should be checked prior to installation of a higher output alternator. Adding a high output alternator will not solve bad or compromised wiring that is already present in the vehicle.
