Deco

The Deco motor has been around since World War II and has been powering quarter midgets almost as long. It's compact size and robust construction makes it a good race engine. Originally this engine produced about 3 hp at 2500 rpm for powering pumps and generators. This antique utility engine has evolved into the racing engine powering the most exciting cars in quarter midget racing.

QMA has 4 Deco engine racing classes:

Super Stock

121 cc max. Cam, carburetor, ports, manifold, timing and minimum flywheel weight specified by racing rules. This class started out as a box stock class, but over the years production changes, lack of original parts and the desire to go faster made it into a "super stock" class. In this state of tune the engine produces over 5 hp at 6000 rpm.

Modified

121cc max. Specifications are the same as the Super Stock class except the timing; carburetor and manifold can be changed. This allows the engine to really breathe. Modified engines typically make over 7 hp at 8000 rpm.

B-Modified

124cc max. Restrictions on the engine block are removed from the modified specifications allowing high flow ports. The "B" engine really delivers a sting and an exciting ride for your driver, producing more than 9 hp at 9000 rpm. Because of the high performance level the QMA only allows the older and more experienced drivers to run the B-modified motor.

AA-Modified

138cc max. and anything goes. Straight methanol is the usual fuel. This is the big daddy of race engines developing 14+ hp and over 12000 rpm. Not bad for an antique, eh?

There are two reasons to get a Ziggy's engine: performance and service! At the Motorworks there is no middle ground, only one performance level, the best. The same is true of service, there is only one service level, the best.

Ziggy has been working with the Deco engine for a decade and knows the secrets for fast and reliable race engines. This high performance level is achieved by constant R&D and closely supporting his customers at the racetrack. When a stronger, lighter, better part is needed, Ziggy does what has to be done to get it. Sometimes this is producing a new design from scratch. Ziggy has designed and developed many of the high performance parts used in his engines such as pistons, rods, heads, valves, ports etc. The Deco design requires careful fit up and assembly for both powerful and reliable operation. Assembled engines are run in and dyno tested to break them in a controlled environment and tune them to max power. Ziggy does not just believe the shipped engine will make the proper power, he knows it will. The combination of design, construction, and testing produces the best engines in quarter midget racing.

Ziggy is concerned with the success of your race team. He provides the engine service that puts your driver in the winner's circle.

Before the race

From your first phone call or e-mail Ziggy's is responsive to your needs. They work with you to answer questions, provide set up information and help you get the most from your race car.

During the race

Ziggy goes to the races and is there to help in the pits and trackside. Of course, Ziggy can't be at all races every week, but he goes to most local races and makes all three grands and major races like the Ohio indoor series and Pumpkin races.

After the race

Ziggy's services Deco engines returning them to 100% performance. Each and every part is inspected, and reworked or replaced, as required. The completed engine is then dyno-tested. Engines that don't pass muster on the dyno don't leave Ziggy's until they do.

[Deco engines are high output engines. Remember, they started out making 3hp and are now making up to 14+hp. They were designed to run at 2500 rpm, and are now turning up to 12,000rpm. This causes these engines to require frequent service. Ziggy's engines are constructed for easy service. Ziggy's Motorworks always works with your race schedule to get the engine back in the car where it belongs, as soon as possible. You can't take the checkered flag if you don't make the green flag.
