Wild Things Performance Continues to Dispel Myths About H-D Performance...

A common misconception is that throttle body size must be perfectly matched to the size of the engine. While it is true that extremely small or extremely large throttle bodies will have an effect on performance, size is not nearly as critical as it is with a carburetor. Carburetors rely on the velocity of incoming air to properly atomize fuel; fuel injectors will provide a perfectly atomized mist regardless of the velocity of the incoming air. Some say that a 57mm throttle body is too big for a 95” engine and will sacrifice torque. The dyno chart below proves this is not true. As you can see, a properly mapped 52mm or 57mm throttle body will provide identical performance in smaller displacement engines. If your stock throttle body is the limiting factor in your current build and you are planning to purchase a larger one, it only makes sense to buy a slightly larger throttle body. You’ll sacrifice nothing with your current build and when you decide to add those Wild Things Billet Heads, you won’t have to upgrade your throttle body again, too.

We cannot stress enough that the selection of compatible components combined with proper tuning is the key to success when building a performance engine. Adding a 57mm throttle body to an engine that is adequately served by a stock throttle body is not money wisely spent. As you plan your build or next performance upgrade, clearly and honestly define your expectations then target only the engine components needed to get you there.

Now you can let your engine really breathe! The stock throttle body and manifold restrict airflow, robbing power, especially from modified engines with large displacement and/or high-flow heads. With this 57mm straight-bore throttle body and high-flow manifold, you can increase horsepower big-time in Delphi fuel injected Harleys. All stock components are reused and will bolt onto the throttle body without any modification. Our throttle body is designed with the stock Delphi air cleaner bolt pattern so it will accept any H-D or Kuryakyn air cleaner. It even allows you to retain your factory cruise!

We’ve also added a version of our Wild Things Throttle Body and Manifold for applications using S&S or other cylinder heads with 1.800” intake ports. The manifold has been machined for improved flow and port match in these applications.
