Tachometer

[bob duffer]

I was thinking of getting a 6 volt tach for my 34 Buick  from Westach.com and was wondering what the main difference is between these .What is good one for my straight 8  ?  

• 5,000 Rpm
• 8,000 Rpm
• 3,500 Rpm

I know nothing about 34 Buicks.  You might want to pose your query in the Buick Pre-war section; below?

 

That said, I cannot envision any 34 Buick engine turning 8,000 RPM.  Be surprised if the engine turned 5,000 RPM.  The lower the high-end on the scale,  the more accurate and easily readable the gauge would be.

I would think that the 5,000 and 8,000 RPM versions would be useless for your application.......unless you wanted to note exactly what the RPM was when it scattered.

Ok thank you .

A 90 degree 5000 RPM one would be the choice since you would be most interested in shift points. You have a narrow band and you can just glance over to see the needle a little right of vertical to make that bang shift.

 

The Buick doesn't lend itself lend itself to road courses where a 270 degree range, 5000 tach would give you a better display over the full RPM range.
