Was checking up on ignition upgrades from Pertronix again and saw that they offer the Ignitor III for our vacuum dizzies now. Supposed to work like a box style ignition without the box(multiple spark, rev limiter). Did a search here and didn't see anything for that model. Anybody used an Ignitor III and have any useful feedback on or off a Porsche? Not looking for opinions on whether or not Pertronix belongs in our cars or not, just on the functionality of the Ignitor III. With that said, I know this may start a (IMG:style_emoticons/default/stromberg.gif) storm..... (IMG:style_emoticons/default/stirthepot.gif)

I've heard of others using Ignitor II but I'm thinking the Ignitor III won't be compatible with the 914 components. I would try calling Pertronix about it first....I don't see anything on their site saying it
would work with our setups. I'm wrong a lot though so....YMMV!

Why would this be better than Permatune? I've had a Permatune on my '71 for years with no issues...

I didn't see anything about Bosch distributors on their site as well. Limited production for Detroit Iron is all I saw.

Part number 71847v. They run about $130 on Summit and Ebay. Curious to know if they are as easy to set up as the ignitor 1 and 2. I like that the whole set up fits under the cap still, but is multiple spark and also has a rev limiter. If the 3 works well in other applications, it ought to do so on a type 4 engine as well. Good price for that kind of ignition control.

I figure if they are listing the part number it will at least bolt in with a possible mod for the vacuum advance that is needed for the 1 &2.

I don't see the specific instructions for the 71847v but the other Ignitor III install procedures look very similar to how the Ignitor I & II install. Buy one and try it out and post a review of how it works....

I've been running a -II on my 2056 for over 3 years now - but I still carry a spare dizzy w/points just in case (IMG:style_emoticons/default/shades.gif)

Opinions on the Pertronix are like reviews on Amazon. Some love/like....some hate. I have Pertronix II. Never bothered me. Either carry spare points, spare Pertonix or have a towing plan with your car insurance. All easily solvable problems.

The Permatune is a Capacitive Discharge Ignition. It makes the spark hotter, and offloads a lot of the current flow from the points. It still uses points, but they pass a low "switching" current rather than the full ignition current.

The Pertronix completely replaces the points, but does not change the way the ignition circuit works. It doesn't make the spark noticeably hotter, but it won't wear like points do.

They're different bits doing different jobs.

I have a P-III on my 65 mustang. Works great. The big diff between the II and the III is that with the III you don't need to install a ring over your dizzy shaft. It senses when the lobe spins around (by the change in magnetic field).

Anyway, my PIII works great. Not sure if it's compatible with the 914. If it is, keep in mind that it either works or it doesn't...it's not like points which give you some notice when they're worn or on their way out. When the pertronix dies, it'll happen in an instant and you'll be stranded. That's why many P users keep a spare set of points or a spare PIII in the trunk (myself included)!

You guys that are using the Pertronix III, what coil and plug wires are you using?
Also, did you increase you spark plug gap?
Thanks in advance. (IMG:style_emoticons/default/beerchug.gif)

I just installed the III and cannot seem to get the engine to idle any one have any experience with getting the III run in a stock 2.0 D-JET?

Also I'm running a stock coil, I checked the resistance and it is 2.3 ohms with no wire attached and am running Magencore Electrosport 70 SS25 200T spark plug wires.

Any thoughts or direction would be appreciated.

Regards,
Dan

I've run a stock and Bosch blue coil with Ignitor 1 but pertronix matching coil with Ignitor 11, I don't know the impedance required for the Ignitor 111 but would be surprised if the stock is compatible.
Do you have the correct air gap between pickup and dizzy shaft ?,1mm from memory.
You can't run solid core leads with the newer ones as per instructions.

According to the Pertronix III instructions, it is compatible with any coil of 0.32 Ohms or greater so should work with stock coil. http://support.pertronix.com/file.php?key=...1a66cdecbd8493f

I recently bought and installed a Pertronix III and their matching Flamethrower III coil but am months away from firing up the engine so can't comment on how well it works.

As Ian mentioned, there is no magnetic ring under the rotor with the Pertronix III ande is no adjustment for air gap.

I have had a Pertronix in place of the points for 15-20 years now, must be a series 1 if that old. Never an issue.

I checked everything even called Pertronix prior to purchasing to make sure the plug wires I had were good. I will have to call them again.

I may need to downgrade to a II or I or back to good old points and condenser.

Thanks for the responses
