Hey. I have always wanted a 200mph speedo as well. You know, it might be time to start making these ourselves. Does anyone have the name and contact info from the guy that used to make them? Contact him and ask him how he did it. Ask him where he got the 200mph overlay and how he calibrated it. This isn’t like going to the moon where they did it in the past but we can’t do it now scenarios, You might only have to make like 50 of them to break even. You can seel them here and everyone would be happy. Start searching for this guy and go CSI on his a$$. Let us know what he says. I might be able to chip in the money to have the overlays printed if he still has access to the original. Get to work young man. Let’s make this happen.
I wish I had the time and resources to do it. Played that game quite a few times in the past. But I don't, so I'm offering a few bucks to anyone who can point me toward one of these existing ones.
The hard part is the calibration. Having the overlay made shouldn’t be too hard. You can even have custom redlines for the tach if you don’t add a number. If I get bored I will start looking for this guy.
Update: I just sent an email requesting this guy’s info. Let’s see what happens next week.

I have sent an email to Maggs and Granitali requesting contact and technical info. Let’s see what happens. I also found these people: https://gmgaugespecialists.com/produ...nd-firebird-v8
Since they are making custom overlays, I don’t why they can’t just print out a 200 version and let people have different redlines on the tach. Let’s see what they say. As far as the calibration goes, I am a 36 years Instrument Technician in chemical plants and refineries. Too calibrate the gauges I will just need to know what kind of signal generator that I would need.
Is there someone out there with a 200mph cluster and the ability to generate more? Some may be willing to pay $200 dollars or more for the 200mph speedo cluster.
I'm hoping you will find someone to do it or try to convince Granatelli to do it one more time if you can get so many offers. I had my first WS6 done with the Granatelli 200 MPH gauge and I loved it. I sent my gauge into them and when it came back it was more than I expected. When you turn the car on the gauge did a full sweep. Totally awesome. Please keep us posted if you find someone.
I have a custom gauge cluster I just pulled from my 2000 camaro not sure if your interested but here it is, I’m going to a Holley digital dash so I have no need anymore! If interested make me an offer, I have everything to make them work complete wiring harness and the corresponding transducers and o2 sensor and oil deal that will go with it, all electric gauges.
I was looking at this place.
you could contact them about it.
Or get a km/h cluster that goes to 240 and calibrate it for mph maybe
Just heard back from Black Cat:
"Thank you for contacting us. We can do the 200mph speedometer scale, 8500 redline tach and change the warning light spelling but we cannot exactly match the factory gauge face style and finish. We don’t have a font available that matches the factory font and we are unable to reproduce the original pattern and finish.
