Mr DeeBeez Posted June 10, 2015 Author Report Share Posted June 10, 2015 yes. when i come to a stop sign or stop light, my voltage drops to 12.9. my car idles lower than the turn on rpm of the alt. have talked to mechman and i already have the smallest pulley. the only thing i could do is send it in to get it wound so the turn on will be earlier, but they said id loose output at higher rpm Yup... not a fan. Most will say to get the LARGEST alt you can fit... what they dont know is, it will not even make amperage till some silly turn on..... Fuck that... my hairpin 270 only does like 266 on music, .. but id does 230 at 500rpm, team that with the big 370, .. i love it. Go do your same tests, and rev that fucker to 2300 rpm.... and report back. EDIT- imho, you give up a lil bit of max output, for more of a "friendly, daily" turn on... its not like your running 20k and need it anyway. Just me..... If all else fails, i will, but my alt is buried in my engine so id need to pay to get it taken out, send it in and be without a car for a couple weeks, then pay to get it put back in.

EDIT- 1700rpm is around where my 370 starts to come alive......

Kyblack76 Posted June 10, 2015 Report Share Posted June 10, 2015 also, just because your running their smallest pulley, means nothing if your crank pulley is not helping..... soooo much to get shit to work right bro...... so much...

Mr DeeBeez Posted June 10, 2015 Author Report Share Posted June 10, 2015 what would you suggest i do? smaller crank pulley? and ill test at 2500 rpm soon and report back... thanks again for the help, really appreciate it.

firebirdude Posted June 10, 2015 Report Share Posted June 10, 2015 (ill be your stock alt charges better than the aftermarket... ive been there) Me too. Damn eBay. Then I wised up and paid for a Irragi Alt. Yeah yeah. This was in... 2002? Idle output was through the roof and I was a happy camper for years to come. As was said, I'd like to see some 2500rpm numbers too. Lesson learned, you've REALLY gotta watch your idle output when shopping for a high output alternator. For a daily driver at least.

Mr DeeBeez Posted June 10, 2015 Author Report Share Posted June 10, 2015 went to a parking and clamped again... rpm at 2600, subs playing 35hz tone full tilt, voltage holding at 13.7, clamp read 30.5A same rpm, tone, voltage, clamped at the amp, read 53.2 Fi Team 18's (4) Crossfire 16k Crossfire 400.4 & 800.4 Pioneer AVH-X491bhs 140ah cmax CES 320's (2) Link to comment Share on other sites More sharing options...
Mr DeeBeez Posted June 10, 2015 Author Report Share Posted June 10, 2015 should i wire down to half ohm, when my voltage REALLY drops, and clamp it then? when its at half ohm, i drop in the 12s not even full tilt...

CleanSierra Posted June 10, 2015 Report Share Posted June 10, 2015 First of all, i think the problem is likely with the charging issue with your car. Get that shit figured out. Dumb question, but it hasn't been asked yet. You were doing all of this comparing between your friend's car and yours. Were you using the same box, subs, etc in both tests? Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
