I decided to take a light mechanism in to the platers with the last batch. I really like the way it came out. I polished up the ring and mounted the Carello's. Then I stuck the trim piece on there for good measure.

These, the Pilots and the Hella's and Aaron and I should be lighting up the night. I hope that 911 alternator can keep up!

I think I'll throw some of these loom melters in there:

130/100W Narva: $19/ea

Any electrical geniuses out there know what is involved in wiring all of these properly and what the alternator needs to be?

I have a couple 911 alternators out of the car now that I could have rebuilt if that's what it takes. Maybe a late model 911 alternator would be able to keep up in a stipped down racer (no radio etc.)

Aaron, can your pops weigh in?

I think it's the same set up you'd be using:

Pilots
Hellas
H4's 130/100

No wires run yet... need advice.

LOL 130/100 bulbs? im using 55/60 for streetabilty....
you will need to run dedicated 12 or 10 gauge wires to the front of the car with relays for that kinda current draw!

lemme ask pops...

55 x 6 = 330 watt draw in my application

http://www.angelfire.com/pa/baconbacon/page2.html

330 watts at 12v is 27.5 amp current draw....

a CDI (msd type) pullsa bout 9 amps i hear
fuel pump = 3 or 4?
various sidemarker and brakelight etc lamps = X amps

27.5 + 9 = 36.5 amp draw, plus ligths fuel pump etc...

dont think a stock 55 amp type 4 alt will handle it

Alright... maybe the 100/55W Narva's and I'll flick the switch when I want to melt deer at 50 paces. I'm gonna miss that 30 watts though! (IMG:style_emoticons/default/dry.gif)

enter 12v, and expected total wattage draw of your lights in the watts...

2 x 55w hella = 110
2 x 55w pilots = 110
2 x INSERT H4 WATT DRAW HERE = x

add em up....

ok.. so 34 amps are dedicated to night lighting.

how much do all the other systems on the car draw?
wipers?
fuel pump?
ignition (BIG DRAW)
turn signals/brake lights/running lights?

etc...

then i would leave at least 10 amp for safety

Would I be right in assuming it would probably need to be around 90 amps? (55+30+??)

Looks like this would do the trick...

911 603 120 05

Valeo 90 Amp for an 84-89 car.

Good ole Ohm's Law E=I X R E= voltage, I= current, and R= resistence. Add up all known wattage loads and divide by voltage and you get your current requirement. Then you want to service factor it by some percentage for safety and inrush current. #10 Cu wire is good for 30-35 amps depending on the insulation, #8 Cu is good for 40-45 amps, #6 Cu will handle 65 amps, and #4 is good for about 90 amps. I like using the welding cable because there are some many more strands, it is flexible and easier to work with than FLAP, or Home Depot residential or commercial wire.

Valspar 55409 "Vanilla". Special plastic enamel.

Color is an exact match. I spent hours trying to clean them up with everything in the book. I took the worst set I had and tried this stuff (I have a couple more sets). The result is what you see.
