    Pertronix Ignition/Coil

    I installed a Ignitor ( not Ignitor II ) ignition on my 67 L-79 about five years ago using the stock coil as the mfg. said it would work fine as it has to date. Not to long ago there was discussion as to using their coil along with the Ignitor. I contacted them and was told if my dist. cap and stock resistance wires were in good condition I could use their 40,000 volt coil without a problem. They didn't say however what the advantage would be to going with their coil vs. using the stock coil. What advantages might I expect by going to the hotter coil without changing my plug gap ? ( They said their testing with this combination using a wider plug gap didn't produce any better results than normal gap in older engines ).

    Re: Pertronix Ignition/Coil

    Saying that a coil is "40,000 volts" is meaningless, but hot rod parts outfits like to advertise maximum open circuit voltage to get big numbers. The actual voltage generated by an operating ignition system is breakdown voltage of the spark plug gap, which is typically in the range of 10-12 kilovolts for spark plugs in decent condition.

    Ask them how much per spark energy their coil will provide compared to the OEM coil. The OEM single point system with a 1.8 ohm ballast is about 41 millijoules. If they can't answer that question, don't waste your money.

    For comparison the TI and HEI systems are 74 and 76 millijoules, respectively - almost double the single point system

        Re: Pertronix Ignition/Coil

        It is probably the thread I initiated, to which you are referring to. I was only interested in utilizing the Pertronix Ignitor module, along with my stock coil, because my car is virtually bone stock and original...including the B-R 270 Delco-Remy coil. I wanted to get rid of the points, setting gaps and dwell is becoming a pain and no one was going to pull my distributor cap in order to see if I still had my points and condensor, but they would notice an aftermarket coil. Pertronix tech support told me, on two different occassions, that the module would work fine with the stock coil, as long as you bypass the resistor wire from the coil to the ignition. They could not give me a definitive answer on the advantages of going to their 40K volt Flamethrower coil either.

          Those bazillion volt coils...

          remind me of something my Grandfather (an auto mechanic and biker from the 1920's) used to say- Most fishing lures are designed to catch- Fishermen. I mean, if switching from a 600 to 750 cfm carb will make the the car run better, wouldn't a 1000 cfm make it run REALLY well?

            I have no idea what the ratings are or mean but I installed ignitor II and their coil about 2 years ago which resulted in a MUCH cleaner burning engine and substantially better response!! I have a restored 67" L79 good Luck Mike Arteaga

              I have used the pertonics I and II along with their coil, worked fine. I would recomend the new crane XRI at 65 bucks. You do not have to worry about the gap from the module to the ring and possibly pull the distributor to shim it. You remove the points and put this in its place. It also has an adjustable rev limitor built in. The pertronics broke up at 5,400 rpm, the crane pulls all the way to 7,000 rpm. I have a pertronics II and coil if anybody is interested. 50 bucks for both along with all of the extra shims and parts also i have the 2 wires covered in black shrink wrap to hid it
