Are you guys stuck in the stone ages? Still using a tube radio in your dash? Running points in your modern driver?
having run a 25D distributor with points on a distributor machine and then installing a pertronix the accuracy was way beyond the point set. And it was a good distributor to start with.
For the purist fine,for someone that drives their B over 10,000 miles a year the pertronix beats points hands down.
You set your timing advance just as you normally would and you can advance it if needed for special tuned engines.
Anyone that complains of looseness ever read the PDF installation sheet?
Your post is why one could say Pertronix advertising is successful. Unfortunately, its not the way things really work. Yes, there may be more energy "available" but the car only needs about 12K volts to run exceptionally well, and unless you gap your spark plugs at .100", you can't produce that kind of voltage. The high quality Igniter II coils made in China or Mexico also won't last but a few sparks under those circumstances. If you wonder why, just ask Pertronix about the company wide coil recall that happened 9 months after I called and complained about coil failures using their product.
The TR6 that made great power actually had no other issues. It was an anomoly for sure, but a great example of a car that ran really well with 99 hp at the rear wheels, but ran exceptional on points. Jack's right when he says most of us will never have our cars tuned the way they were meant to be, because we're happy with the the way they run now and don't want to spend the time/money to get everything out of it we can. Unfortunately, that means the cars won't last as long, running in a mediocre state of tune, some since brand new.
IMPORTANT: The one factor I forgot to mention is RFI noise. If you run a side-entry distributor cap (pre-68 cars) with copper core plug wires, the RFI noise those wires throw off actually blind an electronic ignition from sensing its own signal, randomly. Even with really good plug wires like MSD, Cobalt, or Magnecore, there is some RFI present that can cause a rich misfire from time to time. This will show up as a rich spike on the dyno or a clear misfire on a scope, and causes a significant loss of power. Again, 5-40%. In once case, a TR4 wouldn't run any higher than 1200 rpms before dropping completely dead. Simply changing to a top-entry cap and carbon core wires on that car helped significantly, allowing the car to run with misfires. Adding points cleared it up 100%, as tested in my own personal car and repeated on the customer car in Washington.
Yes, Crane and Allison can have similar issues, but to a lesser extent with healthier electroncis and an optical sensor. The CEI system is great for a daily driver but has an entirely different set of issues due to the way the sensor picks up the signal, and isn't suited for regular use over 5000 rpms.
