advance curve and total advance of Bosch 010?

Depending on his current stock, you can buy a fully reconditioned Bosch distributor here:

I have bought 3 distributors from Glen Ring and all have worked flawlessly...

Glenn doesn't seem to have much stock.

I've had it in my files for years. I think I pulled it off theSamba, but I can't be sure. A search over there for "distributor curve" should pull up no end of charts.

The thing to keep in mind with a mechanical distributor is that no two of them work or advance exactly the same. The bottom line is an 010 generally advances more quickly than an 009.

It's big advantage (the 010, that is) is that it's a cast iron distributor, so the spark is much more stable. If you've ever put a timing light on a cheap distributor and watched it as RPMs increase, you'd be amazed these cars run at all. The scatter is astounding.

Thanks Stan, that's exactly what I needed.

Glenn has no 010's in stock but there are a few on the Samba

Rhetorical question: has anyone here run the BR18? It was stock on some 356 A's and there's a guy importing new ones on the Samba.

Did anyone get the pun in my original post?

Thanks in advance, Will

If you're going to go to the trouble (and expense) of an older cast iron distributor Will, consider an 019. It's generally thought in the hobby that it's advance curve is better in a slightly milder engine with the emphasis on driveability on the street, and that the 010 is more suited to racing, where full throttle and maximum hp are most important. I think I have an 019 (or 2) in my stash that would be suitable for Glenn to work his magic on, so pm me through dialog if you're interested. 

If your carbs have vacuum ports, an svda (both mechanical and vacuum advance) will also have a similar mechanical curve to an 009, while in light throttle situations (think highway cruising) guys report 3-4 points better mileage after jetting the idle circuits leaner.

PS- I don't know about that specific distributor, but some people consider the 356/912 units better in shorter rod ratio engines. I have heard of a few guys using the 050, some more successful than others.  

That said, an 009 works too, as the 3 have similar curves-

Yes I did, Will-you put it in at the end of your post, which is a good thing, because timing is everything.

Is there a source for different advance springs for these Bosch distributors?  I would like to tailor my two 009's but have yet to find a spring source, other than making my own from straight spring stock.  

I have free access to a Sun Distributor testing machine, if I only had the springs.

Might be easier to just get a 010.

ALB, your graph is very interesting- 019 does show a big difference. Thanx, Michael

I have a write up on modifying an 009; I'll look it up later and you can be the judge of if it helps. Al

35 years ago, everybody had a Sun distributor machine.

20 years ago, they were being scrapped for pennies. I really wish I had one.

Ron, this topic has really sparked my interest!

Al, thanks for the offer (019), I'll send a dialogue. My builder doesn't want to exceed the total advance of the 009 so the SVDA is out as it can momentarily advance into the high 40's. He won't warrant the motor if I use one, so I won't!

Yeah... $1000 for a NR parts unit. I wish I had the one the local high-school put out by the curb 20 years ago. Hindsight, and all that.

Like a lot of other tools, I would LOVE to have one, but have absolutely no place to put it.

Besides, if you can borrow time on someone else's...........

It's kinda like the professional, commercial-grade chainsaw chain sharpener I have out  in the shop.  It will literally sharpen any chain out there.  Used it a lot in the 1980's and '90's when I heated with wood.  Now, I heat with Natural Gas - it's cheaper than wood.  If I use the chain sharpener five more times in my lifetime, it might be a miracle, but I still have it.

OK... a few general comments.

There is no one size fits all. I've found the 019 works best with stock to mild performance engines under 2000cc. The 010 works best with mild to high performance engines over 2000cc.

There are many versions of the 009, Bosch German, Bosch Brazil and dozens of aftermarket Chinese copies. I've tested a number of Chinese copies and found the advance can range from 14* to 44*. Quality is poor to abysmal. The German ones are the best of the bunch and the Brazil are not that bad. But I have yet to find a engine that runs better with a 009 than with a 010 or 019.

I do have a refurbished Sun 600 Distributor Tester and can tell you the aluminum body of the 009s to vibrate when run at high rpm, while the cast iron body is much more stable.

I use Bosch 01 016 points in the 010 and 019, they are for the Bosch 022 which was used in the Porsche 356 and have a stiffer spring. I've run my engine to 7200 rpm with no bounce.

Inventory comes and goes. I never know when i'll have one and they generally don't last long. I do have a waiting list. People are asking "stupid" prices for cores, so i would have to greatly increase my prices, so I buy low to keep prices reasonable. If you can find a core, i can rebuild it.

Here's a single purchase i made 2 years ago... they were gone in a month.

It's best to email me at glenn@glenn-ring.com if you want to discuss anything.

Thanks for posting here, Glenn.

Will gave me the link when he inquired about a rebuild.

I figured the discussion might be helpful to others.

But it's best to email me since I won't be posting here much.
