Technical electric tach with Vertex magneto

I'm wanting to use an electric tachometer with a Vertex (internal coil) mag. There are a couple converters on the market that will handle changing the signal to a square wave and read the mag. Anyone have any 1st hand experience with either the Autometer 9118 or the MSD version?

I have a Bosch FST 8050 and a Smith's RVC 2816-00CA neither of them are traditional but I do have them in my stash and do not have a cable drive bottom for my magneto.

Thanks.

 

Don't recall the part number, but I had an Autometer Monster tach in a race car I ran years back. A small Chevy with a Vertex magneto for ignition plower.

Not a problem if that's what you're asking.

Just look into the Autometer part numbers OR...give them a call to verify that your particular tach will work with a mag.

no experience with them but used a Stack Clubman with my vertex and it worked......a bit pricy though

 

The Stack tach is a bit pricey but does come highly recommended. I'm wanting to use the Smith's actually. I do have an email in to Autometer. Thanks.

 

I ran a Cirello "Frankenstein" magneto, the Autometer converter, and a regular Mallory tachometer on the hemi in my dirt car (avatar). It worked fine.

 

I see you sent the mag to Spud, can't go wrong.

 

I have a internal coil Vertex and I tried the Autometer set up but could not seem to get it to work and I had the original Sun tach that used the Mag. sender box. Sent it all out to Williamson and have used it happily for 12 years now. I have a Autometer monster tach and didn't like the way it looked in my MG.

Yes Marty, Spud did the tune up on the mag and he recommended the Stack.

Thanks Pat, I have a note in to Autometer.

 

I'm running an old Stewart Warner with a "Mag" sending unit on mine and it works great. Nice unit's, both tach and sender, are pretty common on E-Pay. That's where I got the one in my heap.

 

I have found from bitter experience that mixing tach types never works.

 

Tubman I did not say that correctly. I had trouble using the Autometer with the magneto and the Autometer 9118 so I went with the complete Sun tach and sending unit. Sorry for the confusion.
