Check out the new TSP L99 VVT.2 camshafts!  

Since TSP is one of the only companies that designs, grinds, and tests their camshafts in-house, they are able to constantly test for better lobes, grinds, and combinations!  TSP camshafts are the result of endless engine dyno testing on their SuperFlow 902 engine dyno using a factory GM L99 engine with factory cylinder heads.  

The L99 Stage 1 camshaft will be a great choice for those looking to use their factory torque converter and want the best streetability possible.  This camshaft will have a slight lope at idle and will be mild mannered on the street, yet still adds incredible power.

Cam Specs: 223/233, .629"/.629", 114 LSA

The L99 Stage 3 camshaft will be a great choice for those looking for a more aggressive camshaft that makes excellent power but not wanting the most aggressive setup possible.  This camshaft will have a noticeable lope at idle and will drive well with a minimum stall speed torque converter of 3,200 RPM.  This cam makes more power than the factory camshaft from 3,000 RPM all the way to the 6,600 RPM peak.

The VVT-1, VVT-2, VVT-3, and VVT-4 camshafts are all designed with more aggressive lobes that require the removal of the AFM lifters from your L99 vehicle.  This will require the installer to remove the cylinder heads & install standard, non-DOD style lifters in place of the AFM lifters.  If you do not 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 an awesome step forward in technology that allows us to create camshafts that make huge high RPM horsepower while still making 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!
