Our Big Bore throttle body is designed to increase performance on your hard tuned motor.
When looking to extract maximum horsepower from a highly efficient engine, the entire intake track must be taken into consideration. If you have a large bore intake, headers, and even cams, then you know how powerful the M50 family of engines can be with the proper bolt-ons. This leaves only so many areas as the bottle neck.
Our 70mm CNC direct replacement throttle body is excellent for the tracked, raced, or extreme street M50, M52, S50us or S52 powered vehicle, looking to release all the horsepower said engine is capable of producing. An unobstructed extra large bore allows peak power, while allowing good throttle modulation.On the M5x / S5x US series engine, the engine has only one throttle to ingest large amounts of air. However, this isn't as much of a bottle neck as people think: When you want maximum engine output, this opening must be properly enlarged so the engine is not 'choked off'. Our 70mm throttle body does just that!
The VAC Billet Big Bore Throttle Body is set to use OBDI or OBDII.
We use this same throttle body on many of our customers racing/hot street engines!
