370-Amp V-Mount High Output Alternator For SOHC Ford Modular Engines

THE WAIT IS OVER!!! A true 300+ amp alternator for the SOHC Ford Modular Engine family can now be utilized in a real-world application. We have 100% solved the poor belt wrap that has held this platform back for years. Since the early 2000's these V8 & V10 SOHC engines have had some of the worst belt wrap for an upgraded high output alternator. With the belt only touching appx. 1.2" of effective pulley surface area, this left little to no grip needed to properly operate a high output alternator over 250 amps. This is having been the reason we are one of if not the only manufacturer to limit our selection to just a 250-amp version for so long. We either do it right or not at all. There are many different fitments and brackets throughout the years on the engines, but we have chosen to include all the necessary brackets, hardware and pertinent items needed to mount this alternator CORRECTLY. Correctly in this case means with a properly designed upper bracket area to eliminate alternator flex and belt deflection. You may or may not need all hardware/brackets included to install on your application. We chose to provide all that would be needed just in case of mid-year changes or fitments that has been discovered. (see all included items in picture gallery) This is THE ONLY alternator of its kind like this in the world for this platform and proves that we look to innovate and not duplicate like our competition. Please be sure to check out our ultra detailed instructions online for this P# to better familiarize yourself with why this is hands down the best option for the SOHC engines. Installation notes: Uses OEM 3pin Ford regulator unless otherwise noted, plug and play. Must use 0-gauge power and ground wires directly to battery for best install performance results. In some/most applications you will reuse and/or relocate your OEM idler pulley(s) to maximize grip. See instructions for belt size recommendations. Optional idler pulley add-ons for even more extreme grip! Please refer to any and all pictures in the included instructions. Fitment is tight in some applications; however, all testing has shown no signs of wear or fail due to fitment location restrictions.

E Series 400 amp Black Billet GM truck 05-13

Installation Notes: This unit comes equipped with a smaller 1.75 inch diameter alternator pulley, and will require a slightly shorter drive belt for proper belt tension. Not recommended for sustained use above 5,000 RPM engine speed. ((Check instructions section for finding belt sizes and wiring)). If you DO NOT use the correct shorter belt, this will result in very low to no output and create extra work load for the alternator. Newly redesigned for 2020, The Elite series offers the highest possible amperage and durability available in a large case alternator. 6 phase technology combined with massive twin rectifier assemblies and 12 diodes makes these alternators totally durable for daily use, while still maintaining 200+ amps at engine idle speeds. These alternators use the more robust 4 pin style regulator than the OE 2 pin ECU controlled alternator. There is no extreme voltage fluctuation as this will bypass the RVC charging system on all 2005> GM truck applications. Simply install the included 1 wire P101 harness to a tested 12v switched source and plug in the included P103 module into the vehicles 2 pin original alternator wiring harness.

S Series 240A Racing Alt - Replaces L Mount CS130 - Machined

The S series of 6 phase alternators offers incredible low RPM output in a compact and durable package. Highly efficient, these units use less horsepower than conventional 3 phase alternators. 12 diodes, twin rectifier plates and outstanding airflow ensure much better durability than standard Delco CS130 based alternators, even in severe conditions. This custom designed housing directly replaces standard CS130 "left mount" alternators as used on 1987-1995 Chevy C1500 Pickups and some aftermarket accessory drives. A single wire on the provided pigtail gets connected to any ignition switched 12V+ source to turn the alternator on and off with the ignition switch. Simply run a properly sized positive and ground cable from the alternator to the terminals of the battery and the alternator will work perfectly, regardless of what kind of wiring harness you have. Because of their compact size and standard GM mounting ears, these alternators also work well in many aftermarket or custom bracket installations.
