That’s probably because you distributor is bouncing all over the curve! Or your compression is down!
An 009 on a 616 engine is not the best idea in fact on any engine.
The first question of any engineer when you ask for more power is “How much money are you willing to spend?”

Re: 912c
009 is ok on a type 1 but totally wrong on a 912, not surprised you saw an improvement there.
What were you running on the 356 before the 6v cdi swap?

Isn't it about time you came to visit us with your 912 so I can shove a CDI+ on it and put this to bed!SeanP wrote: ↑Wed Apr 19, 2023 7:45 pm Neil
Have you read up about John Willhoits development of his engine conversions? It’s an interesting read of all the avenues he went down, twin plugs, CDI, fuel injection. It answers a lot of questions.
What JPS have done is developed an engine package and backed up their designs and products with testing and verification of the results. The very same thing that willhoit has done.
CDI isn’t the be all and end all of all of ignition systems. It’s actually pretty old technology these days with coil on plug systems, crank fire and ecu’s.
These people selling the wares are standing by their products. And if it needed a CDI then they would have surely installed one.
Oh and the arc directly out of a 123 distributor is a pretty lively spark that can jump a bit. That’s why they say not to connect the black wire Shen setting it up and keep it away fro metal things

Re: 912c
Just to be clear my 912 had a 009 on it and I changed to a 123.
My 356 has a 022, which has rebuilt, now I've added a CDI to it. Even before the CDI the 356 has always been the smoothest running car. I think the cam in my 912 had more duration in it
However, on a ride with Sean I can't remember being below 3000 rpm so any distributor would of worked!!

Re: 912c
If your 912 had a standard engine it has less duration than your 356. That’s how they de tuned them because of the additional weight of the 912.
But the engine doesn’t come on cam until its at least above 2700!
