Spark plug connector

[Jesset100]

I did a search on spark plug connectors and have two Questions.

1. Are there spark plug connectors with resistors and without resistors?

2. If so how can I tell the two apart?




The connectors I have (6) are dark red in color and they don't have part numbers on them. The markings that are on them are BREU GERMANY-BELO 6/3 and a symbol that looks like T with the top line kind of bent down and the line going down has 3 tick marks.
I tried to see how much resistance they (6) have and can't get a reading on any of them.
This is after I cleaned everything.

I checked one plug wire that I took these off of and it had 0.00 resistence. The distributor side connector had 2.7 ish.

All Beru connectors (since '68) have resistors. No other choice on those.

Sounds like you have one( or more) open connectors that need replacement.

Or,.................or, you can prevent this from recurring by installing a set of Magnecor 8.5mm race wires. These are FAR better than any OEM wires.

Can you increase spark plug gap when using Magnecor alone, or do you need a blaster coil and perhaps a MSD unit too?

[Steve@Rennsport]

The question of whether you can increase plug gaps to take advantage of improved burn, better idle and a tad more HP lies with the ignition system's ability to support those or not.

You Need:

1) An ignition system with the voltage AND current to ignite & sustain the spark under varying conditions. Compression ratio and mixture play a big role here. Bosch or Permatunes cannot generally do the job for long, especially when high compression or boost is employed. I use MSD 6-AL and matching coils.

2) All of the rest of the ignition system must be in perfect shape otherwise you will burn something. This means: cap, rotor, plug wires/connectors, and plugs.

Thank you.

I've read some people's opinion that it was the original stock spark plug wires (and insulation/clading) which accounted for early and mid-year 911's small spark plug gaps.

If that's the case some surgery will take place with the connectors. When I shake it I can hear something rattle inside. I'm going to drill the resin plug and see what's in there.

I have Magnecor's already, just wanted to make my own plug wires/have a cheap project to do

[Jesset100]

Ok, here is what the inside looks like.
Took some ohm readings:
Woodscrew =.000
Red resistor =.120
Red resistor =.121
Black resistor =.110
Spring =.001
Spark plug clip =.001

Look, I was bored ok
Well if any newbie wants the info it's here

[kach22i]

I had no idea all that stuff was inside of there.

great work!

Steve, you are 100% correct here that's why I ended up retro-fitting a Jeep Cherokee HEI distributor cap and Chrysler HEI ignition cables ( forget Beru or Bosch ) to my 86 3.2 so I could take full advantage of the better performing 0.060" spark plug gap which is probably the most effective ignition upgrade you could do without going to the insaney expensive twin plug option.

Do you have a thread where you detailed this conversion?

[RoninLB]

some pelicanheads reported Bosch CD problems when they increased gap beyond stock. Loren and maybe Warren confirmed this in elec speak.

Personally those Beru connectors and rotor rev limiters are a problem just waiting to happen.

I read in MSD's "Wiring Diagrams and Tech Notes" that to max gap performance is to try different gaps in .005" increments. When the best gap is over widened the performance will fall off.

Here's my cap and rotor conversion:

That's it?

Looks to simple.

I had points, took them out and have a Pertronix ignitor kit (magnetic pick-up).

Would all that still fit under that cap using similar rotor?

Stuff just looks missing to me.
