The L99 engine utilizes Variable Valve Timing (VVT) controlled via a cam phasers. Cam phasers are computer controlled cam gears that automatically optimize camshaft timing based on the current engine rpm. While this technology provides tremendous efficiency benefits, it presents a challenge when designing performance cams due to the wide range of valve timing movement and constantly changing piston to valve clearance.  With the help of Texas Speed's Superflow 902 engine dyno we were able to custom design camshafts & phaser tuning tables to allow our L99 customers the ability to bolt on the ultimate in L99 performance!  Thanks to the Superflow 902 dyno Texas Speed is the only company that currently offers a VVT camshaft with a phaser table included to properly tune the camshaft once it's installed in your Camaro!

The VVT-3 camshaft is a 230 intake duration camshaft that TSP offers for L99 customers looking for max power gains on vehicles with aftermarket torque converters. The VVT-3 camshaft features approximately .620" lift thanks to the TSP VVT lobes & has been tested to make over 100 flywheel horsepower gains on the TSP Superflow engine dyno.  The Texas Speed 2010 L99 test Camaro made over 80 rear wheel horsepower gains with the installation of this camshaft.

The VVT-1, VVT-2, & VVT-3 camshafts are all designed with more aggressive lobes that require the removal of the AFM lifter kit from your L99 vehicle.  This will require the installer to remove the cylinder heads & install standard LS3 style lifters in place of the AFM lifters.  If you don't want to remove your cylinder heads you might consider looking at the AFM-1, AFM-2, & AFM-3 camshafts.  All three AFM series camshafts still feature full VVT control, but they also use weaker lobes that are designed to be compatible with AFM lifters!

Each L99 camshaft Texas Speed offers will require the use of a Comp Cams Phaser limiter kit. The phaser limiter restricts the range of cam timing movement from 50° to 20°. This modification provides the necessary valve clearance for serious performance camshafts with tighter lobe separations – while still utilizing the benefits of the VVT technology.

The VVT technology is a awesome step forward in technology that allows us to create camshafts that make huge high rpm horsepower that also makes great power down low in the rpm band!  The result is camshafts that can make over 100 flywheel horsepower gains while still making great low rpm power!
