As the title suggests, does anyone know if there's a higher output alternator available that's a straight drop in on a sporting?
Alternatively, can anyone supply info on modifying the stock one to give higher output?

Dunno, but I can guess why you're asking this - what's in your system?

Fit one from a Seicento with air-con its rated 10amps higher. This was all looked into about a year ago. IIRC the standard alternator is 65amp air-con one 75amp.

Hmmm, I'll price that up tomorrow

Pioneer HU
Pioneer 4 channel amp
Kenwood 2 way fronts
12" Pioneer TS series sub
Sony Xplod *cough* 6x9 *cough* shelf mounted rear
The 6x9s were in the car when I got it and the holes are far uglier than having a bit of noise in the back
I will get round to removing them and building some 2 or 3 hole speaker pods for the front doors when I get some time.
It's just that I'm always working on the hearse at the moment. I've booked space in a mates booth to paint it on Saturday so it's gotta be ready.

i ran kicker comps up front,JBL 6x9 rears,10" JBL sub,alpine monoblock and JBL 4 channel with no issues.

I don't think a new alt is needed. Do the big 3 and possibly a larger battery.

The big 3?
Where would a bigger battery go? cos it looks like the little tiny battery fills all of the space where it lives.
The headllights only dim on the drops when it's really cranked (45+ on the volume scale with D+B on)

I meant a larger battery as in spec and not necessarily in size

Big 3 - replacing the following with larger gauge cable (IMO 4 awg minimum)

• Alternator to chassis earth
• Battery to chassis earth
• Battery to alt wire

Does a Cento actually have alternator to chassis earth? Never looked....

How does this help?? no having a go,just intressted

The alternator case is the earth.
If you havn't already, fit a 1 farad capacitor.

making sure the power circuit is clean,my word dunno if anyone else uses it.
a car electrical system works on a loop to the battery so you provide power and it flows to earth.a poor earth limits the power available

Does no good whatsoever. I'm sure I've been through the reasons before

Reduces resistance in the circuit meaning less voltage drop across the power wire.

it earths through the engine block.

Yep, gonna make a new battery to body and body to engine lead on sunday.
Good plan
