Fastest Liquid 1/4 Mile

Description of ODBA Race Classes
Lake Racer Class:
ODBA's Lake Racer Class is comprised of production style bass and ski boats, with open cockpits, similar to styles seen on the local lakes and rivers nationwide. Engines are from mild to wild with everything in between and weight requirements are based on the level of engine modification. Spec Sunoco racing gasoline and Klotz Synthetic oil, as sold at the race site is required. Speeds on these lake boats generally run in the 100 to 105 mph range.
Super Stock Class:
One of our most popular classes is Super Stock. This class utilizes the Hi Performance outboard engine, as produced from the engine manufacturer, with no modifications. The favored hull is the venerable Allison 2001 river racer with enclosed deck design. The weight, including the driver, is 1400 pounds and the fuel is our spec Sunoco racing gasoline and Klotz Synthetic oil. This class is designed to showcase boat set-up, propeller selection and driver ability. Speeds in this class can reach 110 mph.
Pro Carb:
ODBA's Pro Carb class is very similar to our Modified Production Class. No fuel injection is allowed but highly modified V-6 Mercury Outboards still tend to dominate this class. Again, Sunoco Racing Gasoline with Klotz Synthetic oil is required and weights are based on engine configuration and displacement. The Mirage Quartermaster and 2001 Allison are popular in this class. E.T.s in the low 11second range with speeds in excess of 100 mph are common.
Modified Production Class:
Another very popular class with outboard drag racers nationwide is ODBA's Modified Production Class. As horsepower levels rise, we begin to see more of the Triad DR20 Intimidators join the hunt for the coveted First Place trophy. Engine modifications are restricted to OEM parts only and most racers opt for the Mercury Racing fuel injection system. Power output is in the 380 HP range from these 2.5 liter based engines. Sunoco Racing Fuel and Klotz Oil keeps the fires burning. E.T.s in the very low 11second range is what it takes to win.
Pro Gas Class:
Now things start to get interesting! Unlimited modification to the powerhead is allowed. Exotic, one off parts are the norm, 1350 pounds is the base weight for the small block Mercury V-6s that dominate this class. The engine must run on our spec Sunoco Racing Gasoline and Klotz Synthetic oil. Look for the Allison, STVs, and Triads to be the hull of choice for Pro Gas competitors. E.T.s in the high 10 second range and speeds in excess of 115 mph are usual.
Pro Fuel:
The name of this class says it all. Any fuel with any additive is allowed. Methanol and Nitro is the favorite for these water borne dragsters. While there very few boats nationwide that can step into this class and be taken seriously, the ones that do really put on a show. Look for more Allisons and DR-20 Triads with a minimum weight requirement of only 1250 pounds including the driver. Big cubic inches with exotic fuel systems that produce E.Ts in the high 9 second range with speeds in excess of 120 mph are what it takes to get the big check in this tough class. It's a crowd favorite and when they run, you'll see why.
Unlimited Outboard Class:
Light weight race boats with Pro Fuel style engines with a big dose of Nitrous Oxide pretty much tells the story for ODBA's Unlimited Class. While the rules are intentionally few in this class, basically anything goes as long as it meets the 1250 pound weight minimum. Superchargers, Turbochargers, Transmissions, and Expansion Chambers are all legal for this fastest of the fast class. E.T.s in the high 8 and low 9 second range with speeds of 130 mph are what we'll see when these bad boys hit the water.

Unlike other forms of Drag Boat Racing, ODBA's starting system closely emulates conventional automotive drag race systems. Elapsed Times (E.T.s) are calculated in a similar fashion. Competitors pair up in the pre-stage area and idle up to the starting barge. Once ODBA's Official Starter determines everything is OK, the Christmas Tree starting system is activated and racers take off when the final lights turn green. E.T.s are calculated from when the boat actually leaves the starting line until it crosses the finish line. No running starts at the clocks with ODBA.
When all is said and done, our style of racing provides lots of close, side by side racing, that showcases both the talent of our drivers and the extreme performance of the equipment.

We would like thank everyone for coming out to support the event this weekend and welcome you all to the ODBA family.
