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
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
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!
