Car won't start, small problem

[91-gsx]

I was driving the car when a altima came around and wanted to race. I went ahead and gave him a taste. Anyway when I was at 7500 rpms the spark cut out in 4th when my redline is set at 8500 via dsmlink. This is due to having to great a plug gap. But the bad things happened right at the end of the run, as in while still rolling at 120mph... First the car dies, then the horns go off whenever the car is on, as in honking 24/7 when the car is idling. The coolant containers shows low in the gauge cluster, but the thing is full. The battery light is on as well. The gauges come on and off while I drive it. It drives fine, but then the gauge lights start to dim. And eventually the car backfired when I would try to accelerate without boost, and with boost.
Any help would be greatly appreciated.

how does your car drive? does it have power, does it back fire all the time?
