Throttle Stops for Bracket & Drag Racing

Adding a throttle stop to your drag racing vehicle is a great way to improve ET consistency and meet your class index time. JEGS offers a wide selection of throttle stops from top manufacturers such as Dedenbear, Biondo, Shifnoid, and others. Each throttle stop is made from high quality components and assembly so you can get the drag racing performance you want at a price you can afford with the assurance you need.

What is a Throttle Stop in Drag Racing?

In the world of drag racing, a throttle stop is a crucial component used by racers to control and limit the amount of throttle opening during a race. It's a strategic device employed to manage a vehicle's performance and achieve consistent elapsed times. The primary goal of a throttle stop is to slow down a dragster or racing car, typically at the starting line or during specific segments of the race.

Throttle stops are commonly used in bracket racing, where competitors aim to predict their own car's elapsed time and try to match it as closely as possible without going faster. This form of racing places a premium on driver skill and consistency.

Throttle stop devices come in various types and configurations, including electronic and mechanical versions. These devices can limit the throttle opening to a predetermined percentage or even close it entirely for a specified duration, allowing racers to precisely control their acceleration and maintain a consistent pace.

How do You Calculate Throttle Stop Ratio?

Calculating the throttle stop ratio is an essential step in using a throttle stop effectively in drag racing. The throttle stop ratio is the percentage of throttle opening allowed by the device during its operation. To calculate it, follow these steps:

1. Determine the target elapsed time (ET): Before the race, you should have a specific ET that you want to achieve consistently. 2. Measure the actual elapsed time: During a practice run, note the actual elapsed time of your car without using the throttle stop. 3. Calculate the throttle stop ratio: Divide the target ET by the actual ET, and then multiply by 100 to get the throttle stop ratio as a percentage. For example: Throttle Stop Ratio = (Target ET / Actual ET) * 100.

The resulting throttle stop ratio is the value you will program into your throttle stop device. It determines the throttle opening during the run, helping you achieve the desired ET.

How Much is a Throttle Stop for Drag Racing?

The cost of a throttle stop for drag racing can vary depending on several factors, including the type of device, brand, and features. Basic mechanical throttle stop kits can start at around $200 to $300. These kits are typically more affordable but require manual adjustment.

Electronic throttle stop systems, which offer greater precision and control, tend to be more expensive. These can range from $500 to $1,000 or more, depending on the complexity of the system and additional features.

It's important to consider your specific racing needs and budget when choosing a throttle stop for drag racing. Investing in a high-quality throttle stop can help you fine-tune your performance and improve your consistency on the track.
