Thats because of all that FAST racing you do, thats always causing your engine to overheat.

I put the whole gallon of the 50/50 mix and the next day i open the cap to the coolant reservoir and it looks like the reservoir is empty. i made sure that everything was tightened and the hose were secure on the radiator and coolant reservoir.

Did you check for leaks??? Wet spots underneath??? On the ground??? Cracks in the hoses??? Or caps?? Any smells??? Just check everything first, and keep an eye on your temp guage while you let the car run awhile. And be sure to check for leaks & smells while it's running.
