After years of r&d, engine and valvetrain simulation and plain down trial and error Virginia Speed is proud to bring you our series of supercharger cams.

We have found over the years that one size does not fit all if you want the best performance from your supercharger. This is why we created a large selection for different cylinder head styles and displacements. The ls3 and ls7 cams also use an intake lobe that is better matched with the larger intake valves to reduce valve float at high boost pressures.

These cams reflect thousands of hours worth of dyno and simulation work-the cost of this is in the hundreds of thousands of dollars,but you can buy all of this work for the low cost of $425.00.
