Technical Tachometer Reccomendation

Discussion in 'Traditional Hot Rods' started by vespaholic, Nov 11, 2025.

  1. I have a '28 A with a banger.
    12V conversion
    FSI Electronic Ignition
    I'd like to run a period correct ('40's) tach.
    Can I get a recommendation?
    Anyone have one for sale?
    Thanks!

    "period correct (40's) tach" and "FSI Electronic Ignition" are in direct conflict with each other. "period correct (40's)" would be a mechanical drive tachometer and I would doubt any electronic ignition distributor would have a mechanical tach drive. If you can settle for a "Vintage Look" tach, there are a number of "old style" tachs available. A Google search will yield units from Bosch, Mooneyes, and several others. eBay in particular has a selection.

  4. I should have said Period correct looking....
    I've seen the units on eBay but most say untested and/or do not specify 4-cyl vs. 6-cyl vs. 8- cyl engine.
    So that why I was looking for a recommendation.

    Regarding if I need a tach....I don't.
    I just think a period looking tach would look cool.
    That's all

    Can’t really recommend a tach but If you find a tach you like here’s an idea. check out www.technoversions.com

    I’ve got a 34 ford pu with a 59a flathead, efire distributor, 12v and a column mounted vintage Sun football tach.

    TechnoVersions sells a product TachMatch that uses a small circuit board to match any tach to any engine. Doesn’t matter if 4,6, or 8 cylinders. You can mount their small circuit board inside Sun transmitter or hide it under the dash (my preference). Works well.

    I second the tach match. I put one on my 56, they eliminate the sending unit and you can choose the number of cylinders. I think they are less than 100 bucks

    I'd look for a tach that max rpm is 4,000?

    Marine tachs often operate in the rpm range of a banger.

    That's a Bosch "Sun Football" tach "look-a-like". I don't think they have been discontinued. I have one and like it, but I'm a sixties guy too.

    I wish it was a 6000 rpm but you take what you can get!

    Why fake it, find a pedestal tach drive and an early mechanical tach. Tach drive in the photo is Stewart Warner and tach is Jaeger.

    That's a great idea. Now, where do we find a Stewart-Warner tach drive for a FSI Electronic Ignition?
