Tachometer tech

Postby EEricson » Mon Jul 17, 2017 5:03 pm

Hi all.

I'd like to hear from any who have sprung for the slightly bigger, 8k tachometer as seen on original Spyders.

My kit came with what looks like a perfectly serviceable 105mm chinese repop 356-style 6k tach. The speedo and combo gauge are also 105s (and not the period-correct 100mm size).

The holes for them are pre-cut and nicely centered.

I think I could squeeze a 914 tach in this cluster (115mm). Am I wrong?

If I'm not wrong, what's the most reasonable way of getting the Spyder-correct 8k sweep? Can you start with a common 7k dial and have Palo Alto or North Hollywood convert it? About how much does that run?

Is it worth shelling out for the 914-6 tach (factory 8k) or not?

Any way to get the new Speedhut unit without the GPS speedo or funky non=Porsche-looking combi gauge?

Any help & advise appreciated.

I have the bigger 8K tach from Vintage. Call Greg and ask what the price is. You can get the existing tach redialed and calibrated, but it may be cheaper to just buy the bigger tach.

914 cores from eBay. North Hollywood or Palo Alto Speedo to reface to economical 550 standard (no insets for warning lights). Order instrument cluster panel from Fibersteel and let Russ know you have 914 cores. Use Russ' panel as template for altering existing openings. Add backer if required. Most
Economic way to get correct look.

Cool. Any idea what N. Hollywood charges to redo a 914 tach?

I used Palo Alto. Either shop should quote ballpark as it's fairly ordinary for them. Did all three gauges cause you're looking at them a lot!

Its been a while but I bought a set of 914 gauges on e bay for about 100.00. They were shipped to Palo Alta and completely redone. All 3 were around 1,000.00 give or take 100.00. If you plan to go with the authentic gauges you need to do all 3, the 356 style made in china knock offs just don't look right. Back then that was the only option if you wanted authentic looking gauges. Now, as Dan pointed out Greg has authentic sets for sale.

This is all very helpful.

I was hoping to just do the tach and put the existing speedo and combi in. Re-thinking now.

Greg's are close, especially the tach, but he says his bezels won't match the other gauges and the center dots are a bit smaller. I'd buy his straight away but the combi gauge isn't quite period-correct, and neither are the odo windows & such.

Beck and Sierra Madre have new correct-sized 356 gauges by VDO and they look pretty good. But of course the tach is 100mm. It's actually smaller than my 105mm Brazilian (guess) re-pop holes.

So maybe the 914 set is the way. $1,000 tho is pretty long money to replace gauges that should work fine. I suppose I could sell the existing set...

Or maybe keep them and build a Speedster around them later.

Note how the warning lights are inset on the combi- this is authentic but he quoted me $500 more for the indents vs flat. I went flat. May have changed since then. Did get the temp gradations as shown.

He charged me an extra 400 or so for the indents. I think they look great.

I'll call him. I still wonder: any 914 gauges get the treatment for the same $$? Or do you need the 150mph speedometer to get the 150 back? Any difference in price for turning a 7k tach into an 8k tach?

Any. Tell him what you want. Not just a reface they check them out and calibrate them.

Just looked up my invoice. Its #184251 dated June 22, 2010 and the total is 1,117.00 including shipping. The price also included a fuel sender and an oil temperature sensor. That price also included an extra 300.00 to do the indents/insets around the windows for the oil, gas and odometer displays. I didn't opt for, or perhaps they didn't offer the indent/insets around the oil and generator lights. Seems excessive to double the price over 7 years.
