I tried to do a search but I was going throught 2008 thread and still haven't see anything to answer my question. I can't believe it. Am I the only one who thought about upgrading his alternator ??

I think the easiest way would be a infinity J30 alternator that do 140 amp for dirt cheap but would they fit? I also heard that higher output alt. takes some HP away?

Basicly, please help me out if you know something about upgrading the alternator.

custom rewind to near double the current at most high end alternator shops, it will drain HP and sometimes the idle speed too , a different pulley is a issue. they make the most power about 2000-3000rpm engine speed which is normal driving speeds

you can order one from USA but it wont be cheap, you can get higher voltages if your into super SPl amps runnning 16v but most other items in the car will fry

aBattcap is another way to go? mine is 400 amps from soundstream plus i use additional capacitors

upgrade all charge and grounding wires to at least 4ga, stock is 8-10ga to alternator and car fusebox.....mine is 4ga and 0ga with extra grounds in engine bay, frame

and use a high end battery and clamps

my system pulls around 350amps peak now (3 amplifiers )but will pull more once me new amps come from usa , my lights dont even dim on bass

Edited by sapphiregraphics

what brand/ models and ohm loads are they runnning. you can pm me if you dont want the public to know

3 amps can run with the right support,

my old VR4 had 5 Unregulated power supply class A/B Alpines in it on more or less stock everything under the bonnnet. except a red top battery 11years old in it..lol.

but then my old Commy R8 had 1 of my current amps and the ECU would malfunction and lights dim bad on heavy bass at idle. the voltage would get sucked down so fast in one hit. 1 ohm load per channel.

odessy battery ended up dying, and so did the voltage regulator inside the alternator. Its a bit of the luck of the draw sometimes, on how well the electrical holds up.

I can forward a link to a guide on what to update before the alternator. on imports they can cost a mint to redo or replace.

if you can let me know if your already having issues as well I can help further

i rewired my old commodore alternator to Delta and went from 120amp -200 on the test bench but didnt charge till 1000rpm. when pulling up at the lights at night it would dim right down. never changed it back when i sold the car...wonder if new owner ever figured it out :rolleyes:

    • ok so if i wanted to go 18's i would go for 8's  in front 30+ or 32+ off set at front and the back 9 would be ok? what offset should i aim for.. then can i do some  hunting for wheel rim choices..    If i get this - will this fit all around: Size: 18 x 8.5 +37 - n what tyres size tyre should i get for front n back?  
    • Absolute f*cking nightmare. I had to take breaks constantly, and I was always pissed off when I got home. The line split in Italy on day 2 (we drove from the Netherlands), lol. Driving any narrow European town was... well, sh*t.   Appreciate it man. Here, I'll just drop a favourite from the load I took on Saturday.   I'll update here when things happen with the car, the thing is, with stock power and almost everything chassis-wise taken care of, there really are no problems. 268,000kms now and counting.  
    • Ah! I actually managed to snag a lightly used set.... that aren't so suitable for me right now. They don't work on a GTT without some cutting or creative heat moulding. I thought about reselling them myself cause I didn't want to murder them, but it looks like I'm probably going to attempt to murder them/melt them because I may as well. @GTSBoy @PranK can somebody close this thread?
    • Hey mate,  I have a set, one is slightly damaged but wont be noticable once installed.  Shoot me a message if your still after them 
    • I couldn't wait But, the black constant tension hose clamps were too thick and there wasn't enough clearance at the T/B and I couldn't get it to seat properly, so I had use a silver one there I also added some 3" silicone over the alloy bit that goes through to hole on the radiator support as it looked like it was sitting on the edge of the hole in the radiator support, I never noticed a rattle or anything, but there was a witness mark It is basicly done, and I can live with the silver hose clamp at the T/B, I will get a black clamp for the head vent though where it is attached to the bulkhead fitting  It never stops...LOL, only issue now with the shock tower brace is it slightly touches the under bonnet liner now, if I leave it it will either wear some paint off the brace where it touches, or damage the liner, so I removed the liner to see what I have to work with, with the liner removed I have about 20mm of clearance, but sadly the middle part of the underside of the bonnet is only dusted with paint and looks crap, so I cannot have that, but.... as I have a roll of Carbuilders premium under bonnet insulation in the garage laying around that is only 5.5mm thick (we were going to use it on the boys Patrol, but he crashed the front of it a few months and it was written off, hence why he now drives my old Honda Accord Euro), I'll use the OEM liner as a template and get the Carbuilders stuff fitted up to cover that dusted paint up
