Trying to find all the hidden horsepower in a racing engine can be an exhausting task and Wilson Manifolds aims to make that process easier. The company has been researching different throttle body designs to help EFI racers and their new “Fatmouth” 4150 Mono-Blade Throttle Body is the fruit of those labors. This new throttle body has already seen active field duty and helped propel Shawn Pevlor to a pair of wins in his familiar small-tire Mustang.
Wilson Manifolds saw an opportunity to help racers that use an engine with a 4150 intake manifold gain a whole lot more airflow, and the 4150 Mono-Blade Throttle Body allows the racers all the benefits of a 4500, without having to do a conversion, and it outflows a standard two-inch bore 4500 by 400 cfm.
According to Wilson Manifolds Dave Secunda, the new Mono-Blade unit is a huge upgrade for racers.
“In a fuel injected application you’re not haunted by the loss of signal as you increase the throttle blade size. Take for instance an 8,500-9,000 rpm small-block drag engine with a carburetor: the throttle blade size that will make the most peak power will have trouble drawing and atomizing fuel at its lower launch rpm. The fuel injector allows the tuner to give the engine optimally atomized fuel on demand,” Secunda explains.
Radial tire standout Shawn Pevlor proved just how good this new throttle body is at the track recently. Pevlor won two races in a row beginning with a huge win in Nitrous X trim at Lights Out 8, followed by this weekend’s Carolina Nitrous Nationals with the 4150 Mono-Blade Throttle Body on his car.
