Twonnie Posted January 31, 2018 Report Share Posted January 31, 2018 I was hoping to hear a little about what kind of alternators you guys use / have used and what your experience with them is. Like what size is it, for what vehicle, how many, what is it powering, what is it putting out? ...did it fail, is it nearly indestructible, did you have to customize your vehicle to make it fit (and how so?) Basically any information you provide would be really helpful. You can only find so much information from digging on the internet before you have to start asking questions. Anyway, I want to buy a new alternator for my Pontiac g6, but I'm really unsure of what to get. The biggest alt I can find for my vehicle is a 240 amp. Basically I'd like to be able to have a more than sufficient power supply if possible. I don't think there is any room to run a second alt under the hood.. Which would be nice. But I was thinking if there was a way for me to make a custom bracket to mount a bigger universal alternator.. that would probably be best? If anybody has personal experience with a g6 and alternators, please let me know! I would greatly appreciate any personal experiences, suggestions and feedback Link to comment Share on other sites More sharing options...
alex912005 Posted January 31, 2018 Report Share Posted January 31, 2018 I'm running a Singer 270 A alternator with 2 Northstar AGM31Ms (one front, one back), direct fit, no modifications. The only problem was the threads for the screws were on the opposite side. So the exhaust manifold heatshield and the oil filter had to be removed to have room to put the screws in. Clamped it and did 140 A at idle through the 2 runs of 0 gauge welding wire, but there is the stock wire too so maybe it makes more. Couldn't clamp that one because it's routed different than the 0 gauge. Check my build log for more info on amps and pictures.

WalledSonic Posted January 31, 2018 Report Share Posted January 31, 2018 Made a template out of wood for a Denso Large Case alternator Threw some dimensions in CAD and had these plates waterjet cut for $35/ea Welded some spacers on Here it is next to the stock alt.

Kyblack76 Posted January 31, 2018 Report Share Posted January 31, 2018 Where do i start... Ran a SINGER in my acura tsx, sold it, put another hairpin in it, singer again,.. Ran a DC power 320 in a eclipse Ran a 350, then a 350 with 270 hair pin, then 370, and 270 hair pins in a blazer, custom made dual bracket Run 4 270's now, all hair pins, in a burban, all singers..... Yip, i love me some singer. I like him and Dan at USALTS, only alts id run. Dc Power bracket, took a ton of work, to get it relaible for us. But, it is. I have a SINGER regulator coming also, so we can ditch those fucking pile of shit transpos. But, Matt at mechman is a cool dude, and DC power makes sick product. Cant go wrong with any of em..

Markous Posted January 31, 2018 Report Share Posted January 31, 2018 I have used a couple of Mechman alternators myself, they've performed great for me and my Ranger. I see the CES Alternators brand name thrown around alot on a facebook group that i'm on just as another alternative.

Twonnie Posted February 1, 2018 Author Report Share Posted February 1, 2018 Thanks for sharing guys! I'll have to take a closer look at how my alternator mounts. I know it has 3-4 mounting bolts, but there are one or two in a weird spot behind the alternator. I have machinist / welder friends that could whip up a bracket for me, just need to figure out if I can try cramming a bigger alternator in there lol Link to comment Share on other sites More sharing options...
Kyblack76 Posted February 1, 2018 Report Share Posted February 1, 2018 Kinda remember bro, biggest isn't always best. Your turn on speed may be to high, and you may see dick at idle, which is a pain. That's why we run just 270s. They work better for what we wanna do. (We compete in long, average runs, where your foot can't be on the pedal) The 270s smash the 370s at 400 rpm. Nature of the beast. I'm not failure with your car, or how much power you wanna run. But a nice, HO alt, and some bank, can run a good bit of power. My 350 old school, with d7500s did me more than fine, on a Dc 10k at .5. If I saw low 12s, it was rare. All depends on what your doing. Just my experience. Seen a ton of members on here, in the lanes, and on the street ask why they dip so hard at idle, when they are packing a 370 amp alt. Fucker won't turn on at 350rpm. Or what have you. Something to keep in mind. SMD SUPER SELLER The Burban Build Blazer Build sold Acura trunk build sold Link to comment Share on other sites More sharing options...
Broke_Audio_Addict Posted February 1, 2018 Report Share Posted February 1, 2018 Ran a dc power 270xp for a few years, thing was a beast. Wish i wouldnt have sold it. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.
