Vengeance Racing has five levels of performance packages available ranging from mild to extreme to meet your power goals while retaining GM’s OEM LT4 supercharger. Our performance packages start with three levels of simple bolt-on modifications that will increase incoming and outgoing air flow, increase boost levels by overdriving the supercharger, and lastly improve the vehicle’s supercharger cooling system in Stage 3. These bolt-on packages allow for like-stock drivability keeping the car mild mannered on the street, but a monster on the track! If you’re still looking for more performance, our Stage 4 and 5 packages let our technicians dive into the valvetrain of your engine to further increase air flow and efficiency of your engine, and provide that signature sound that everyone loves from an aftermarket camshaft. The Stage 5 package offers the most performance output possible on pump gas with the stock supercharger in place while still keeping reliability and street manners at the forefront of the performance results. These packages are also completely customizable to meet anyone’s goals and needs, including but not limited to methanol injection, E85 compatible fuel systems, drivetrain and suspension upgrades, and much more. Make sure to consult your sales associate to see what further options are available with these already powerful packages!
