High-Flow Throttle Bodies for LS2 Engines
The new Professional Products LS2 Throttle Bodies feature some unique design characteristics. The stock LS2 throttle body is designed for the throttle blade to open at the bottom. According to GM engineers, this promotes a better flow of the incoming air into the manifold the way it was originally designed to occur. With all other aftermarket LS2 throttle bodies that have mechanical linkage on them, they open from the top instead of the bottom. We incorporated a small gearset in our throttle body that allows the butterfly to open the way it was originally designed by GM and the way it is supposed to for optimum air flow and maximum power and torque. Additionally, because the LS2 throttle body is so large in diameter, when you first step on the gas, it will allow too much air to enter the engine causing the car to literally leap forward. While some people might like this, it can actually be dangerous and will get old after driving the vehicle for a while. We have designed our throttle plate so that when you first step on the gas, only the lower portion of the throttle plate is opening. This only allows half as much air into the engine as found on most other aftermarket throttle bodies. Once the throttle is about 10 to 15% open, the bottom half of the throttle plate allows air to enter the engine. This provides for much smoother takeoffs from a stop. This is also the way the O.E. throttle body is designed. These are all features that we include in an extremely high quality die cast throttle body, with a very competitive price to boot! These are sized in 96MM and 101MM where applicable.
