All the advice I can give is, slow down.
First of all, get rid of that excuse. Getting rid of carbon? Hitting the
rev limiter in all gears? Really?
Do you know your engine doesn't care what gear your in? 4K
rpms is the same in first gear as it is in 5th gear? So don't use that nonsense in court.
For the charge you are facing, I hope you have money. You are going to need to hire an lawyer. You can very well lose your license for this or best case senario, keep your license but not be able to afford the insurance to drive for a long time.
If you were clocked with technology, radar or laser gun and the cop shows up for your case, you are probably finished without a lawyer. THe judge won't even want to talk to you if you don't have a lawyer representing you. The only thing you will be asked is, "what do you have to say for yourself" Nothing you can say will make any difference. Your lawyer will be able to work you out a deal. You will never have to say a word.
I am sorry if this sounds brutal, but I am being honest. It is what it is. Slow down and get a lawyer. Tell him you screwed up and ask him if he can help you to move on from your mistake. That's all. Man up and learn from this. And please be safe from here on out.
