When was the first year that Lexus started
...to put speed limiters on the cars.
Like I have taken my 1990 LS400 to 146mph. I would like to know what year and what models they first started putting speed limiters (I think they're called governor chips or something) on the cars so that you can't go over a certain speed limit.
Speed is important to me
. I'm thinking of getting either a GS400/GS430 or a 1998-2000 SC400 and modifying it for a racetrack just outside Los Angeles where I live. However I'm not sure how I would overcome a speed limiter in the car's system.
Someone recommended I build the engine and put headers and stuff. I'm not sure how much power hp or speed that would add though. Twin turbo charging or supercharging would probably be the last item I would add.
So for all the Toyota/Lexus car modders out there, I want your help!
I would greatly appreciate your knowledge!

You mean your interested in top speed? I've hit the limiter on my GS 400, I saw 152 on the needle. The car had maybe 10 more mph in it easy.
The key is 2 things.
1. Getting rid of the speed limiter (optional on many European cars)
2. Getting the engine to drive past its redline.
The good news is the LF-A will top out over 200 mph!

I just checked up on the Lexus webpage about their future concept vehicles.
The LS-F, GS-F, and LF-A look absolutely marvelous. I wonder what kind of power they will have under the hood.

I bet it would, with 380hp 4.6L v8 I'm sure it would go very faster. 170 or 180 perhaps? More? I can't even imagine the momentum a heavy car going that faster would create. Do you think that it could keep up with a Bentley that goes 200mph?

1. Does your engine have enough power to make more speed
2. Does your car have outstanding aerodynamics
3. Will your gearing allow for those speeds.
Basically wind is your biggest enemy going 150 plus. You are trying to push your car through the wind. Thus you can't have big spoilers and drag. You can't have a low redline if you have 5 speeds BUT with an 8 speed auto, you may just be able to hit 180. The LS has one of the lowest drags of any car, I think a cd of .25 or .26.
Then you have to be concerning with "lift" and hope the LS is designed so the air leaving from under the car won't make the car flip.
