What alternator are people running these days? | ||

For most of my SBC builds I install a common auto parts store alternator. Select an alternator of 80 - 100-amp rating. In some situations, a factory mounting will work, in other situations a custom mounting will be built. It will be wired just as if it were an OE install. I see no reason to do otherwise. One thing of importance, select pulleys that limit the alternator speed. Spinning the alternator approximately engine speed is completely sufficient. Larry Woodfin | |||

My wife bought me a 16 volt super mini from HOP 2 years ago for Christmas. It's a quality piece of equipment and does the job well. | |||

I use one 12v battery and never charge when at the track………… NEVER!  | |||

PM sent. https://postimg.cc/gallery/np3zpruo/ "Dunning-Kruger Effect" -a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge. Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue. 4X NE2 CHAMPION. 2020 TDRA NE2 Champion | |||

East Coast Ultra Mini 16 volt on mine. Seems to work okay. I put the maintainer on it at the track but lately it seems I can't get past first round so no real reason. LOL Clowns to the left of me, Jokers to the right. Here I am....... | |||

If you have a 12 volt system I like an oem gm alternators. Easy to wire in and also easy to find a replacement if needed. As Larry said watch pulley ratio so you don’t over speed the alternator. If on a 16 volt system then I would probably go with house of Payne. | |||

Good advice for a circle track car. For drag racing I use 2 to 1 which I believe is a better choice. Some engines idle very low which can limit the alternator output. My engine idles 1400 rpm both in neutral, as well as in gear. I use 2 gauge charging wire. Power Master site says their alternators will take up to 20,000 rpm for short periods. | |||

My old single wire alt couldn't keep up with the demands and the car was inconsistent. Once I installed a grid, I could see the alternator struggling to reach 12v after the shift. It would actually drop to 10v and barely make it back to 12v by the end of the run. I installed a 100amp Powermaster single wire alt and it straightened out the problem. 72 Nova "Hooptie" | |||

I've had a Powermaster alternator with the low mount aluminum bracket and pulley on my car for over 20 years. It works fine, had to have a regulator replaced once at a local shop. Keep a spare belt but have never needed it. Have a volt gauge on the dahs so I can see it's working. 12V simple and reliable. | |||

Running the alternator my car was delivered with new, 63 amp Delcotron, 1-wire converted, running 1:1 pulley ratio, with a single Group 31 battery. It's adequate. "Despite the high cost of living, it remains popular." Dave Cook N375 | |||

If using a high amp alternator be sure to use at least a 2ga wire. The 10ga wire that came with the switch panel wiring kit come to find out wasn't big enough  | |||

Agreed on the 2 gauge minimum. If tying the alternator wire to the starter (my preferred method) using the same size wire on alternator as battery to starter is a wise choice. | |||
|
| DRR Sportsman |
Agreed! One of the most common errors on race cars. BG | |||

People must have some rockin stereos in their cars to need all of that amperage. | |||
|

Agreed. LOL ____________________________ 2017 and 2018 Osage Casinos Tulsa Raceway Park No-Box Champion 2018 Div4 Goodguys Hammer award winner | |||
