From: Scott D, 1/7/07; I thought I'd send you my thoughts on what I'm running in "Rufus". I've gone with a RSR 0012 distributor from Will at CSP using a Pertronix Ignitor inside, instead of points, along with a standard Bosch blue coil. This is paired up with a set of Will's standard plug wires and Iridium spark plugs. Keeping it all in line is a Pertronix digital rev limiter, also from Will. With this combo in place I haven't had to touch the system for over two years. My engine originally came to me with a 009 distributor in it and it didn't run like a Porsche. Now it's a pleasure to drive. When all is right with the carbs (remanufactured split-shafts) and the ignition, these cars perform very nicely. Keep up the good work and hope to see you at an event soon. Scott D. From: PAUBOOKER; I had an 050 in and it ran pretty well. Then when I put on
a set of Dellorto's I got my hands on a 205 from one of the VW hot rod
shops. Centrifugal advance and a vacuum retard for heavy loads. Works
awfully well. It did come with a rev limiting rotor that had to be
disabled. From:
Robert Burn; ; I
recently replaced my original, terribly worn 031 distributor with an 009.
The car runs much smoother now, but you have to adjust the timing just
short of "pinging" to get the best acceleration. Bob Burn From: John
Wieler; I
recently purchased a nice 68 912 . As the orig 061 dis was worn I thought
I would install a 050 unit , After installation and a quick check on
timing (3 deg after with a strobe) the car has NO power in the city to the
point it has to be run up to about 3 k to get it moving (burn that clutch
to get it moving) then it lurchs and jerks all the time this is the 2
dist. with the same results, the old 061 although worn was a least street
drivable , this 050 is actually makes the car a liabliliy on the street
due to erratic acceleration. I have checked the timing, points and about
everything I could think of but to no avail. From: Steven Thomas; I am in need of information on electronic ignition for my 1967 912.... recommendations...pros and cons....... Steven Thomas, Santa Rosa, Ca. From: Wendell Hartley; Hello Rick, thanks for this great site. It is much appreciated. I have used the 050 since 1983 in my 69 912 & noticed a significant performance increase especially when used with the Dellorto carbs. I use the original coil and use the "fyrebraid" ignition cables. One advantage of the 050 (for those that still change points) is you can use the 044 points which are available from any VW parts house for around $2.20. Sure beats the high price of points for the 061. I am considering using either the Pertronix or the Compufire in the near future. Good luck to all. Wendell Hartley. From: jerry kingman; rick- i just went through my motor and changed to weber 40 carbs. to the ignition i have put new premium wires from GRP which seems to be about the best co. for prices on most things. also i have bosch regular plugs, not platinum. i have put in a new bosch blue coil and a new 050 distributor with a pertronix igniter which i like because of its compact size how it fits into the distributor body with no external box. i couldn't believe the distributor was only $75 new! now i have a complete new ignition system. jerry kingman 67' snrf. coupe From: Douglas Melvin; I like the 050, the
advance curve is correct. The curve and total advance for an 009 are NOT correct for these
cars! A bit of wisdom imparted to me by "The Maestro
follows. " The .009 is a VW Distributor with only some 20 degrees advance. The .050
has some 28 Degrees Mechanical Advance (Range: 26-29, 300+ tested), and works Just Great
with 5 Degrees Static and 33 High Speed, MUCH BETTER than ANY VW Distributor,
the .009 included! Because of the lousy combustion chamber design, VW
Distributors have about 20 degrees mechanical advance, that plus the static VW timing of
7.5 degrees gives 27.5 Max. The Porsche Combustion Chamber, being of much better design,
tolerates a High Speed Timing of 35 +/-2 or a range of 33-37 degrees. I think 35-37 is too
much for the gas these days and prefer 33. From: Matt Cooley; Hi all, does anyone have experience running a Bosch 009 distributor in a 912 with Weber 40IDF carbs. The motor is otherwise stock. I have heard conflicting points of view. This is a street car with an occasional track event. Thanks, Matt Cooley 1967 912 From: mark v. hillman; I have a question before I answer the ignition system question. Can anyone tell me which wire on the back of my '67 tachometer connects to the coil/distributor? I have a "12v." spade connector, another with a " - " negative sign, and one that has the number "1 " on it. I am assuming the 1 terminal is the correct one, but would like to confirm that.My motor uses an 031 distributor (added), Berol yellow wires (VW), stock (Bosch) plugs, and points (soon to be replaced by a Pertronics unit, fitted to all of my former points cars). Thanks From:
Mike Day; I use a Bosch 050
distributor with standard coil, wires and plugs. It runs great! From: Jones Low; For the past year I have been
running the following ignition setup with very good results: From: Ron Bateman; I bought my 912 as an uncompleted project car. The engine was out of the car, in rebuilt longblock form. It had a 009 distributor, and another 022 in a box of misc. parts. Also in that box was a Mark Ten B capacitive discharge system, which looks a lot like the Permatune unit. I haven't hooked it up but I am curious. Anyone heard of this system? From: Robert Burn; I still have the original vacuum advance distributor (031 I believe) that came with the car, un-rebuilt! Since the car has been off of warranty (12K miles) I have had a Delta Mark Ten CD ignition system, that was replaced with a newer model about 15 years ago. I use a Bosch "blue" coil, heavy duty ignition wires from Performance Products, and Bosch W6BC spark plugs. Given the cost differential between the 031 and 009 distributors, I would be very interested in hearing how to retrofit the 009 to a '68 that was designed to use the vacuum system.

From: Jerry Allston; I have replaced the distributor with a 009, Bosch platinum plugs, blue coil, Permatune CD ignition and the Pertronix Ignitor. All work well together, the engine is smoother than before. I finally can get a good lower idle without shaking the car. Pertronix folks were very helpful with tech questions regarding my combination. Also I'm not on the ragged edge during emmissions. I was able to run in and out without detuning (ie crawling in and out of testing). Thanks again for the forum ! Jerry Allston plate 68 912 Arizona. From: Chris Smith; Hi Rick, I installed a Pertronix
Ignitor on my 912E a couple of years ago and put a Bosch blue coil on at the same time.
This summer I installed a MSD 6A ignition on the car and advanced the timing a bit more.
It made quite a difference in all respects. I've heard about Pertronix problems but I
haven't experienced any such problems myself. I mounted the MSD on the drivers side rear
engine compartment where it's out of harms way. I installed some high performance shielded
plug wires and I'm looking into replacing the coil with a matched unit from MSD. Hope you
had a great holiday season and keep up the great site that we all appreciate soooo much. From; Kanas, Jon B; Which ignition system?
Bosch 050. Converted to a pointless ignition? No. Plan to convert to Perlux
Ignitor when car comes out of storage in the spring. Capacitive discharge unit? No.
Switched coils? Yes; Running Bosch Blue coil. Sock ignition wires? Yes, with
Beru ends. and plugs? Yes, regular Bosch copper-core. Car did not run properly when
I attempted to use Bosch platinum. From: Giolli, Florio; I use an .050
distributor and the complete pertronics ignition system(coil, wires and ignitor). This
seems to work really well and has made the engine run stronger. No more changing points to
boot. Who's better than me. Now if I could stop the oil from dripping from the oil sump,
it would be nirvana. Flo From: Jason Terada; I'm running the
original cast-iron distributor in my '66 912, which I rebuilt using a kit and parts from
Stoddard. The kit included a new set of insulators, screws, terminals, etc., to exorcise
this vintage distributor of internal shorts, grounding problems, and to get rid of all of
those buggered-up bolt heads. In addition, Stoddard sells a Teflon sliding surface for the
ignition advance weights, which I used, since the old plastic one had a groove worn in it,
and was cracked in several places. I also replaced the advance weight return springs with
new ones. From: Dean Klein; Bosch 050 - that's the
one Harry Pellow, aka "The Maestro" recommends. I also have a "Blue
Coil" and stock ignition and plug wires. From: JohnFLacey; I had them use all stock/OEM replacements in my rebuild, except that the spark plug/ignition wires are siliconized. Still changing points and plugs, etc., twice a year. John L. From: Ian Gunney; The engine that I am currently building for my 66 912 has an 050 distributor -all else standard. Ian From: TDVW66; 009 with compufire. From: Ron Anthony; H.N.Y. Rick!! We used the stock distributor (having had it checked out) with the Pertronix Ignitor instead of regular points and an electronic ignition. New plug wires and new tech plugs all seemed to help as well. The AL-6 (?) helped make the engine run much smoother. Ron. From: Gregg Dunphy; I'm currently using a somewhat modified version of the stock ignition in my 912E. The car came with a "blue" coil when I purchased it in '91. Otherwise it was completely stock. I added a Pertronix ignitor shortly thereafter and replaced the original ignition wires at the same time. More recently, I replaced the vacuum advance/retard unit with a similar part from a 914. The 914 part features the same retard curve as on the 912E -the only side of the dual diaphragm the 912E uses! It also had the virtue of being available -unlike the 912E part. I will probably switch over to an 009 with an Ignitor eventually as I like the comparative simplicity and improved reliability offered by the 009 compared to the stock distributor as well as the reduced timing and spark plug maintenance offered by the ignitor electronic ignition. compared the the stock points and condenser. Gregg DunphyFrom: L.C. Mixon; Bosch 022, Accel Coil, 8mm hi-per wires, Bosch Copper+ Plugs. L.C. Mixon, 1967 912 (1SXY67) From: Bill Todd; Happy 2000! I use a Bosch
"009" distributor with Compufire Electronic Ignition Module installed. It was
easy to do, and has been trouble free, which I can't say about the Perlux unit. I'd
installed one of their pieces of junk early on, and had problems with it. Their lousy tech
support didn't deem it necessary to respond. So much for Pertronix! From: Mort Marley; Re your inquiry about ignitions. 912E s/n 1733 was retrofitted 10 years ago with an Allison XR700 optical ignition, eliminating maintenance. It has not been touched since. The kit was purchased from J. C. Whitney but I haven't seen it in recent catalogs. Write or call Allison Performance Ignitions, 905 Columbia Street, Brea, CA 92621, 1-800-937-3887.
