Realistically, the installation of this plenum and a 75mm throttle body on very mildly modified vehicles will add at least 8 rear wheel horsepower, and it is possible to receive as much as 11-15 rear wheel horsepower and up to 20 ft/lb of torque on more heavily modified vehicles with a good combination of bolt-ons. Supercharged vehicles can expect even bigger gains, where improvements of between 15-25 HP should not be uncommon. Stage 3 Motorsports will not be undersold on this product.
