We’ve all had them at the track from carb or NOS backfire. The minor ones are put out by cranking the engine to smoother flames by sucking them into the engine.
However, I’ve seen many an engine become toast when that helpful guy runs over and sprays his CO2 fire bottle down your carb. I seen many a race jacket become garbage by throwing it over the engine to smother because nothing else was available. Worse yet, I’ve seen cars burn down while Racers ran around looking for something to put it out.
I’m betting that 90% of the bad damage could have been avoided if the racer had a Fiberglass fire blanket mounted inside his trailer door and/or to the back of his driver’s seat.
Pull 2 tabs and a 3.5′ X 3.5′ fire blanket to throw over the fire. A four pack is less than $40 on Amazon. I have one mount on the inside door of each trailer, and on the back of my driver’s seat on both cars. You might want to consider doing the same. Share this link with your racer friends. I also have a 10 pound fire bottle mounted to my trailer doors if the blanket won’t do the trick. At the least, the blanket will protect the top of the motor from inhaling what your fire bottle is putting out.
