These boats are an excitement to watch. Two types of hulls are currently being utilized, watercraft and outrigger style. Engines are limited to 500 cubic inches. Top Fuel Hydro may utilize only nitro-methane (65% minimum) and alcohol (pure methanol). Top Fuel Hydros thunder down the liquid track at speeds in excess of 250 mph and elapsed time of 3.396 seconds, all this in 1000 feet. A conventional and out rigger type of boat hull designed with a tunnel between the front sponsons for these purpose of trapping air and lifting the bottom of the hull to ride all or in part above the surface of the surface of the water. A W- drive propels these crafts down the track with twin props that rotate counter to each other at 20,000 rpm's.
Traveling at speeds of 200 plus MPH and impressive elapsed times of 4.322 in 1000 ft, the driver must be on his game each time. Top Alcohol Hydro may use alcohol (pure methanol), nitro-methane may be used with an unblown alcohol hydro. Blown or supercharged engines, as well as un-blown fuel engines may not exceed 565 cubic inches. These machines utilize both V-drives and w-drives and the out rigger style hull made its deput in 2011.
These are the funny cars of the drag boat world. They too run the 1000 foot liquid course and set records that exceed 160 MH and lock down 5.2 elapsed times. These hulls are different from the hydro style, this bottom of which is relatively flat with a minimum length of sixteen feet, with no horizontal breaks. hence "Flatbottom" or "Flatty. Top Alcohol Fuel utilizes the same engine dynamics as the top alcohol hydro except screw blowers are not allowed. You will love watching these water machines race down the track.
Otherwise known as, "Pro Mod". This has got to be one of the most competitive classes in the drag boat series. Running a quicker elapsed time in this class is not what a driver wants to do, 7.000-7.999 seconds, with emphasis on 7.000 is the goal. This watercraft runs with the same engine specs as, Top Alcohol Hydro and Top Alcohol Fuel only without a limited on cubic inches, nitrous oxide is not allowed in professional classes with exception of Pro Modified. A hydro style hull and v-drive make this a crowd favorite on the liquid quarter mile.
Pro Eliminator is another exciting, competitive class. Engines may be any cubic inch displacement; whether naturally aspirated, supercharged or fuel injected including electronic fuel injection systems. Fuel can be gasoline, alcohol (pure methanol or ethanol), nitro-methane, E-85, or nitrous oxide. These racers must stay within 8.00-8.99 seconds index to compete, and you don't want to be left sleeping at the light or you will find yourself back on your trailer and watching the rest of the day.
9.00-9.99 seconds index is what top eliminator is all about. Engines dynamics and fuel specs, are same as Pro Eliminator. Blowers for the sportsman classes may utilize superchargers or turbochargers with blown engines; however, proper blower restraints must be used as required based upon fuel utilized. TE is the first class that the racer is required to have a drivers license. What this means is Top Eliminator to Top Fuel Hydro each have a specific license in which the racer must meet and pass the required criteria for class desired in order to compete.
Sportsman class continues with modified eliminator or Modified Eliminator and bring us to 10.00-10.99 second index. This will be the last class to compete in prior to going into the license classes. Any hull design in acceptable with the exception that no blown engines will be permitted in any sportsman class jet boat with a v-bottom. Sportsman classes run the full quarter mile.
The index of 11.00-11.99 is the slowest index in the Sportsman classes which is stock eliminator. This race boat has the same class structure in engine, blowers, fuel, and hulls as Pro Eliminator, Top Eliminator, and Modified Eliminator. Slowest maybe misleading as this class goes down the track at speeds of 95 plus mph. Come on out and give it a try.
River Racer means just that. This is a 12.00 second or slower dial - in class that is very competitive. Whether a veteran racer with a racing boat, or a novice racer with the family boat or fishing boat this class lets you com out and see just how good you are. Once you try it, there is no going back. In River Racer fuel, blowers and engines specs are the same as the sportsman classes. No competitive license require.
If you are 18 ears old and up and want to begin racing, or already have a personal water craft and you would like to see what the racing world is all about than Personal Watercraft 1 maybe for you. Dial- in is the name of the game here, where anyone can win on any day depending if your asleep at the light or cross the finishline first. Personal Watercraft's must use gasoline (4stroke) or gas/oil mix (2stroke).
Personal Watercraft 2 is designed as a entry level class for the teenage racer with approved water safety class and parental consent. Personal Watercraft 2 racers learn to gauge the start clock, mph and elapsed time as different aspects of winning the heat. These water craft post speeds of 50-60 mph in the quarter mile.
