Finally there is an alternator upgrade for the Supra that is powerful enough to support electric cooling fans, twin fuel pumps, ignition upgrades, and upgraded stereo systems without draining the battery at idle and low engine speeds. The PHR/Denso uses only genuine Nippon Denso units with custom windings, larger cooling fins, and a high-capacity internal voltage regulator. Denso is the world leader in quality and reliability, which is why we chose to incorporate them into our high-end alternators.
Output current is conservatively rated at 170 amps cold and 150 amps hot (compared to 90 amps cold on the stock six speed). The most important quality of these alternators is their idle speed output. An engine equipped with electric fans, twin fuel pumps, and other electronics can pull over 70 amps at idle, resulting in a drained battery over time. The stock Supra alternator outputs just over 45 amps at idle, whereas our alternator upgrade offers over 110 amps at idle speeds! We highly recommend the use of the Optima Deep Cycle battery for maximum performance with this alternator. Includes all mounting hardware, a high-capacity 2 gauge shielded battery cable with 200 amp fuse, alternator pulley, and harness adaptor plug. This is a direct bolt-in replacement with no modifications necessary. Another Powerhouse exclusive, and carries a full one-year unlimited mileage warranty.
We choose quality components based on our experience. Anyone can pull parts out of catalog and put alternator together. It takes experience to know how to build a reliable high output alternator. When we choose a supplier and their products, cost is just one of the things we considered. We do not use inferior products, period. If fact, if there are two parts that are similar, but one is a little more expensive and a slightly better fit for the application, we’re the kind of company that chooses the better product. Our philosophy is simple, we don’t want them coming back because of a product failure. As an example of our philosophy is your customer’s alternator that is here to be serviced, it never failed. This is quality statement that you won’t get with just anybody’s products. We are proud of the fact that this alternator worked for him all this time and is now ready for it to be serviced.
