Speed Limiters

so i had two question about this.

1. my 08 V6 limits at 105, and i know there used to be alot of talk about this but how can the speed limiter be removed?

2. In a closed environment on a racing track, what would be the highest safe speed with stock engine, suspension, tranny, and such?

Any response is appreciated, thanks.

What do other models top out at?
I had my 07 GT coupe up to 125 and it was still going...
Was the limiter removed on mine by the previous owner?

The 05 GT is limited to 135. Tune will eliminate it and as long as you keep it in a straight line on a closed track, you can take it as far as the car will go until it's drag limited.

Note that a "chip" is not a tune in case you feel like going on ebay.
