bosch twin plug rotor?

[TRE Cup]

Hi
Still on the search for a bosch twin plug rotor, new or used.
Tried German Auto in St Louis already

[cstreit]

BritWrench had one at one point, or at least knew of the whereabouts...

I think Steve Weiner might have one or two, but understandably is guarding them closely.

You know, I think THIS would be a much better oportunity for a co-op agreement ala Waynes idea with the GT flares from a few days ago... If you could produce these in a decent quantity, they'd most certainly sell...

[cstreit]

Okay so here's Chris' crazy idea... ...someone tell me why you couldn't get a really high output coil and use a Y harness off each plug on a single distributor to make a twin plug one...

Andial says no way jose- they are working on a company that says 1-2 years before they have them!
btw- Bosch lost the molds to the originals when they were in the moving process

Andial had one for one of their distributors - they sent me a pic of it a few months ago for the new book...

would this be for the old 911 4 cam engine? where a dizzy cap can cost $300

[TRE Cup]

Steve / rennsport doesn't have any and yes the caps are in the $600-800 range now.

so that means that the rotor is for the old 4 cam engines.. like the engines that Gary at Parts Obsolete has?

[TRE Cup]

There is probably a difference between the magnetti and the bosch rotors dimensionally. the caps should be interchangeable. We found a magnetti rotor and will report back if it can be converted for use on the bosch shaft

[RoninLB]

OK.. I was at the Parts Obsolete Camp Out last spring and hung with a shop owner for a few days from Glendale/Burbank.. a small 356/911shop.. if you can't find the name.. I'll start digging.. he has many of these crazy parts..

Dave, I think your on the right track ...

I think I heard someone converting an old Maserati twin plug 6 distribuator and cap ... unfortunatly those are just is rare... but

Cheers,
Chuck

I left a message for the burbank shop- will post results
thanks!

Another shot in the dark here; you might check with the Alfa guys. I restored a '64 TZ (many years back) that I'm fairly certain runs a similar twin plug rotor (although the cap differs due to the number of cylinders). Many of the factory race cars ran twin plug heads; e.g., the GTA's, TZ-1, TZ-2's, etc.

You might give Phil Reilly and Co. a call. (415) 924-9022.

Cheers, Chris

Is this what you're looking for?

Oops, better pic.

[TRE Cup]

yes! i want... I want.... pant, pant,pant!

[Paul Thomas]

The good news is; you're welcome to it.

The bad news is, what i am pointing to in this pic is a hairline crack. If you want i can ship it out there and you can have a look. If you want it, fine, if not ship it back.

Ummm.... You wouldn't happen to have TWO?

Chris, we two-point-eighters must be naturally nuts - I had the same idea. I can see why a super-dooper coil with a Y-connector wouldn't get the job done. The plugs are in effect shorting, so with two one would likely win and the other loose completely.

My thought was to use a standard dizzy as a trigger for somekind of dual coil setup. Mind you I'm no electrical engineer, but it sure seems a dizzy working with a low-power discharge could provide a signal to trigger a pair of ignition circuits.

Any automotive, EE types care to comment .... ?
