022 Bosch distributor?

Does anybody know the advance curve for a cast iron 022 porsche distributor? I located a NOS in box Bosch 019 and I´m going to test and try it against my 010 just for fun on my 2276 engine.
Now I´m tempted to source a 022 ditributor to have my collection complete and try it too :-)

it has a lot of advance in it. I don't have specs in front of me, but my friend "tried" one in his 88 x 74 and it was a dog. Couldn't run much initial advance, which his motor didn't like. I think the advance came in slow too.
My opinion is find an 010 instead if you can.

Well I´m a distributor freak:-) I already have a 010 on the engine:
I also have another two new 010 in my parts cabinet (from unused military industrial engines)
And now I have a NOS 019:
Now I have a non running distributor tester I´m going to repair. But I probably overthinked the 022 thing a bit..

The 022 is a Porsche distributor, and from what I remember the advance is all in very quickly, something like 1500rpm, and doesn't work very well on our engines- the engine tries to catch advance at an idle! The 019's advance is more like an 009(?), and the 010 is somewhere in between.
I drove a friends bus last week, he swapped out a 010 and dropped in a 019... Man that thing drives waaaayy smoother...

Bosch 022 is for the 356/912 and has 32-34 degrees @ 3000rpm
Bosch 019 has 17-18 degrees @ 3200rpm
Bosch 010 has 21-22 degrees @ 3000rpm
The VJ4BR8 has the exact same curve as the 019.
The problem with NOS parts is you can't use them.

Glenn,
The Dellorto Superformance book talks about the Bosch 205 distributor as being the best for hot street engines. It is a SVDA. Do you know which model distributor this is and what they were originally installed?
I have a distributor where the VW part number ends in 205 but it is a vacuum advance only, not a SVDA.
The only time I see 205 mentioned in the Old Volks reference page is in a VW part number.
http://www.oldvolkshome.com/ignition.htm#137031
Closest i can find is VW 043-905-205, Bosch 0231 170 034 which is being reproduced in Mexico and may be what aircooled.net is selling as their SVDA(which I have and like very much).
Thanks in advance(pun intended),
Jeremy

the 019 with one spring works great on a small engine (had it on a 1641). it was great in the type3 but it would even be better in a lighter beetle IMHO. the 010 will be good in a plus 2 l engine.

Thanks Glenn and others for valuable info, I´ll most likely pass on this experiment and save some money.

I´m still thinking...was it a nature of a Porsche 90HP engine that it needed so much advance in such a short time?

It's the "semi-hemi" shape head... sort of what Berg did.

The 019 was designed to work with 2 springs... not one. Using one might speed up the advance but cause the advance to be jittery.
Bosch had the 019 out before the 010. If removing one spring on the 019 gave it the 010 curve, Bosch would of just done that.
The 019 has 17 degrees advance while the 010 has 21 degrees. Removing the spring will not change that.
Trust me... i've tested it.

i didn't get about the advance curve.
From this curve means 010 is better in high RPM but 019 is better in low RPM right?
Which one match on 1.8-2.0L engine? Or depend on other factors?
Please advise....

Yes... I like the 019 on stock to mild performance engine and the 010 on mild to high performance engines.
There is no single spec like displacement that decides which to get. Displacement, heads, compression, cam, carbs, driving style all contribute.
A 1835 or 2007 with 8.5cr, W110 cam and dual Kadrons would be best with a 019. The same engines with 9.5cr, W120 and dual IDF would work well with a 010.
I've never had a customer tell me they didn't like the one they picked.
