Don't forget to add that the family dog, always faithful, will shake his head, and walk away from you. You may find him frequenting other households that have VW buses simply because he no longer trusts your judgement.Amskeptic wrote: ↑Sat Jun 17, 2017 5:48 amruckman101 wrote: ↑Thu Jun 15, 2017 5:41 pmI put pertronix into Bertha at one point.

I have been howling for years about using Valvoline Durablend molybdenum-fortified semi-synthetic grease on the rubbing block. Then you get thousands upon thousands of happy trouble-free joyful driving. If you don't, your life unravels into recriminations, breakdowns, firings, marital strife, it is really rough.

Is there any one whose ever considered and successfully installed coil packs on the VW aircooled engine?sgkent wrote: ↑Mon Jun 12, 2017 2:17 pmneal - the amount of energy the coil can pickup and release is finite. It diminishes with RPM. As the RPM gets higher the actual time the points are closed is less and less. The same is true of the time that the energy comes back out of the coil. That is why modern engines use coil packs, one for each cylinder. It helps with the time issue because 1 coil is being split 1 time instead of 4, 6 or 8 which reduces the chance of saturation. FWIW the electricity and magnetism work at the same speed flowing in as flowing out (generally considered to be the speed of light - electro magnetism other than resistance in the circuit). If they didn't flow the same in both ways it would change the law of physics re conservation of energy. Some physicist will probably prove me wrong with some quantum theory but that is the general idea. In fact someone will probably explain that in quantum physics the points are both closed and open at the same time in parallel universes.
I am in love with my trusty breaker points and condensor. Only recently, did I discover that I haven't even pulled the points since March of 2017, and I have been around the country twice since then. And I forgot AGAIN to even look at them when I decarbonized the heads last week.ktk833 wrote: ↑Sun Feb 27, 2022 9:24 amIs there any one whose ever considered and successfully installed coil packs on the VW aircooled engine?sgkent wrote: ↑Mon Jun 12, 2017 2:17 pmneal - the amount of energy the coil can pickup and release is finite.

I would consider such... but if given more understanding on what triggers the pulse for the coilpack to fire...
I hear you. I agree. The simplicity in the points system gives plenty of confidence...& doesn't take that much to maintain.Amskeptic wrote: ↑Mon Feb 28, 2022 10:30 amI am in love with my trusty breaker points and condensor.

Points will never strand you dead. Coil packs can. They are triggered by a cam position sensor. That can strand you dead.
