So what’s the scoop on 009 distributors? Options

[Tdskip]

Seems like they were all the rage years ago and now are out of favor?

What sort of engine build/tune would work well with one of these? Yeah - I have a NOS the shelf.

Thanks!

Thanks gentlemen, will find a T1 home for it.

Appreciate the info and coaching.

From @porschetub reference (and in case other people find this via searching)

"Although unsuitable it will still allow your engine to operate just not as well as the stock distributor. The technical reason that the 009 is unsuitable is that it advances 20-22 degrees maximum under all conditions so the total advance from the static setting of 7.5 would be about 28-30 degrees. Since the VW engine needs varying amounts of advance under partial throttle conditions the ignition system can't keep up with the demands of the engine. This can be compensated for partially by setting the static advance to 10 degrees but since the 009 only has one advance spring inside (weak) instead of two (weak + strong), the maximum advance also comes in too fast (around 2600rpm).

When the 009's first appeared in the mid-seventies as a replacement for the 010, they were adopted by the performance crowd because their aftermarket carbs lacked the vacuum port to drive the vacuum can. Because the advance was too slow using the stock dizzy, the quicker advance of the 009 helped to compensate at the expense of a flat spot just off idle and poor gas mileage. The flat spot felt like a surge of power so everyone felt good about their purchase."
