Well, since your car is not stock, it's hard to give a stock answer.

I would say just go out and test it yourself, but it's not as easy as

just glancing at your speedo as you're flying down the road, 'cause speedometers can be very inaccurate, especially at either the high or low reading side.

So what you need to do is this: drive around for a while until you notice a speed trap and note the cop's position. Then drive about two miles away (which should give you enough time to get up to speed). Try to time things so that you hit maximum mph a few hundred feet before you pass the cop. Then pull over and ask him what his radar gun said. His gun should have been tuned with a fork that day and is going to be much more accurate than your speedometer.
