Big Mouth 92mm Throttle Body™ incorporates major upgrades, including redesigned linkage for smoother operation & improved throttle response
When it comes to improving your engine’s performance, increased airflow is generally a key ingredient. The newly released FAST™ Big Mouth Throttle Body™ for the FAST™ LSX™ 92mm Intake Manifold increases airflow through a series of innovative design changes and a slightly enlarged throttle opening. When used with the new FAST™ LSX™ 92mm Intake Manifold, FAST™ has put their “manifold where their mouth is” in terms of enhanced engine performance and drivability.
But the increased size of the FAST™ Big Mouth Throttle Body™ is just a small part of the added benefits. FAST™ invested significant testing and engineering resources into optimizing cross-sectional flow and eliminating airflow turbulence, especially at part throttle operation. In addition, these throttle bodies offer increased throttle blade thickness to eliminate deflection commonly found with other throttle bodies, especially those in boosted applications. A smoother operating offset blade pivot improves throttle response, and a beefed up linkage and dual throttle spring mechanism ensure total throttle control. The new FAST™ Big Mouth Throttle Body™ will deliver bolt-on GM Gen III & Gen IV horsepower and maximize the potential of performance upgrades.
:Specifics:
New throttle body designed to work in conjunction with new FAST™ LSX™ 92mm Intake Manifold
Better airflow than 90mm units due to enlarged throttle opening and refined internal design
Dual throttle spring mechanism & beefed up throttle linkage for total throttle control
Increased thickness throttle blade and shaft resists deflection, especially in boosted apps.
Smoother operating offset blade pivot for improved throttle response
