Pro bracket racers know that an alcohol carburetor is the only way to go bracket racing where the rules don't require gasoline. Alcohol carburetors from PitStopUSA.com offer double the consistency of gasoline carbs and virtually no engine cool down time between rounds. It's almost impossible to overheat a properly jetted alcohol engine. Alcohol doesn't add much horsepower, but it does adds lots of torque and typically nets a tenth or more quicker times and about 2 or 3 mph faster speeds.
