Re: Noob question about speedo limit

No just means the factory speedometer pegs at 85. I believe at the time it was a federal mandate. If you want you can replace the unit with aftermarket gauges, or go hi-tech with a heads up aftermarket device to display all functions on the windshield.

Here is a thread over from nastyz28 dot com: '81 Instrumentation Recommendations - NastyZ28.com

Re: Noob question about speedo limit

I like it to be as close to the origin it can get so i don't want to replace the panel.
I should get my camaro in few weeks (Shipping over seas) but I just wondered if the 85 MPH is only a visual issue or the car is really limited for 85 MPH cause it slow

Re: Noob question about speedo limit

Well the federal law only lasted for only a few years, passed in 79, and repealed in 81 and some manufacturers such as Audi/WV/Porsche group offered to retrofit 79,80 and 81 vehicles with 85'ers to 120 plus versions, however some manufacturers continued with the 85'ers until major redesigns of their models and that's why a few GM lines kept the lower units in production.

I think but not sure that Z28's using the same gear driven clusters after 82 had 120 mph versions that in theory would drop in no issues and be as close to factory as you would get out of the box.

There are shops re-calibrating the 85 to 120 using new face plate. So you can stay factory looking with the original mileage intact if that is important..

I don't mind the cluster.
I'm just worried that the Camaro has limitation to pass the 85 MPH and it won't go faster

Nope, drive as fast as you want, but look in the rear-view for the blue and red flashing light every once and a while.

Re: Noob question about speedo limit

As Brian suggests, it was a Federal mandate for OEM's in having 85 MPH speedo's installed.
The Feds felt it would slow people down as this is when 55 MPH speed limit came about and the gasoline crisis.
Feds thinking if speed limit is 55, why indicate higher? Let's make it less ...
Slower MPH = higher MPG = less fuel used, less emissions, blah, blah, blah ...

Classic example of why Federal mandates cause consumer's expense.

Re: Noob question about speedo limit

At the time the 85 mph speedometer mandate was implemented, they did not have computer speed limiters or such devices (o.k., heavy gas-powered trucks have used governors on their old carbs). One appalling thing they did have however was the use of crappy tires that would not hold up beyond 85 mph. Tires like the Goodyear Viva & Uniroyal Zeta.

What I find ironic is that the highway speed limits are lower where I live than they were more than 40 years ago, yet tires, brakes and handling for the average car today are so much better than back in the 60s. Combine that with vigorous enforcement and punishing fines and it becomes evident that speed laws are artificially low yet the bureaucratic will to address it doesn't exist. I had heard it said by the Police that "if we raise the speed limits, people will exceed them too!" Nice logic, especially when there is now a deep fostered opinion that speed limits are artificially low and not based in a believable reality.
BTW, my license is clean.

When you get your car take it to the limit and keep on. I had a 75 chevy suburban that only went to 100, I had a bunch of friends in it a while back and freaked them out when I laid in to it. The 100 mark was about the 4 O'clock position and I had it past that to around the 7 O'clock position. One guy said your going a hundred plus... aaaah good times. It had a 454 headers intake and good big carb. It was fun to drive. Just watch out for the man. or anything else that might get in your way. Drive safe....

Re: Noob question about speedo limit

One note of interest since the Fed regulation for 55 was voluntary, states not accepting federal highway money did not observe it such as Nevada. And of course Canadian marketed vehicles had full functioning MPH speedometers however they reduced their speed limits in the 70's for metropolitan areas to 60 and elsewhere 70 mph - KPH after they switched over from imperial units in 1977. I'm not sure what limit if any the 81 speedos had in Canada. You can most likely have yours rebuilt for full range. Speedometer Repair Service - US Speedo

And here is a good video on swapping out old 80 for new 130 speedo.
