Rigging an engine to prevent speeding

Is there a device and/or a special mechanic who can rig an engine to go up to a specific speed? Can anyone help me with an answer and who I should contact? Would this require me to purchase a brand new car or could it be done on a previously owned one? I own a Hyundai Sonata - 4cyl (2006).

Any help would great be appreciated and would warrant a donation.

Thank you.

Well this is something that has been available for years. Truckers have it on their vehicles if the company opts to limit the speed that their trucks are allowed to go. The item is called a "Governor". I may have spelled it wrong.

My problem with a governor is this. If you get yourself in to a situation on the highway where you need to have that burst of speed to get out of a situation, it will NOT be there.

Why not trust to the cruise control and commit yourself to using it religiously?

I almost got into a serious wreck because of a governor. I do NOT recommend them.

Well my work is trying to prevent people from doing burnouts and speeding through the plant on our forklifts, so they put bolted a metal peg under the gas peddle, so the peg hits the floor before the gas peddle does which stops it. It stops extremely hard acceleration and reduces your top speed.

Not sure how well it would work if you tried it on a car. It's pretty much the simplest and cheapest way of doing what you're asking.

Sorry to say that this method is not suitable for vehicles on the road.

For forklifts, it operates mostly on level grounds and speed is not a factor.

For vehicles on the road, the vehicle is designed taking into consideration the power to weigth ratio and the different gear selections.

If the throttle is restricted, it is going to affect the performane of the vehicle and when going uphill, you would not have sufficient throttle opening to pull the vehicle up.

The most commonly used is the speed lmiter as with the add-on governer.

Japanese vehicles are limited to 180 kph ( 110 mph ) by a speed limiter programmed in the ECM and when the speed is achieved, the engine would dut off. This is operated by signals from the speedometer.

There are after market devices for delimiting the speed cut but I do not know if it can be used for reducing the maximum limit.
