Texas Speed Heads/Cam L99 2010 Camaro Nearing 475rwhp

Just thought I'd give you guys a update & let you know we're right at the 475 rear wheel horsepower number & 430 lb ft of torque out of our heads cam L99 automatic camaro! The VVT & PRC CNC ported L99 heads are doing great! The combo is virtually stock compression so it's easy to see how the PRC aftermarket casting heads might very well put this car very close to the 500rwhp range! Move over LS3 cars the L99 cars are really starting to shine!

The car currently makes right at 100rwhp over the stock heads & cam combo!!

I'll post dyno & video/sound asap!!

This camshaft here is the largest camshaft we offer, and at right at 230 intake duration it needs a stall! I'm testing with stock stall because it's the best for dyno testing consistency.

The VVT-1 camshaft is the smallest of the L99 camshafts. It has low 220s intake duration so it's small enough to be stock converter friendly. THe VVT-2 camshaft is the middle sized camshaft & features a mid 220s intake duration. The VVT-2 is a great driver camshaft that ideally needs just a little bit of stall converter. The VVT-3 is the largest of the camshafts we currently offer. It's a big power camshaft that will require a stall converter without a doubt!

Any chance of seeing an idle clip of the VVT-1 in action, and what would be the RWHP gains of the VVT-1 cam.
I can't really afford to be able to do the stall converter as I believe either the engine, or tranny need to be pulled to do that, and that is gonna be pricy.
So the VVT-1 will most likely be the weapon of choice, also my camaro is mainly a daily driver with long KMS trips all summer long, so I need longevity over maximum power.
Last thing I want to be doing is like our race sleds, where you race for a day and wrench for a week, not fun anymore. I just want to enjoy the camaro with the muscle car sound she deserves.
Thanx for the fantastic work you guys have been putting into the camaro.

Great numbers dont mind me asking what lift are you running on your VVT-3 ?


I understand its hard to get a large lift with a L99 so I have heard just wonder what lift you have with power coming from your Cam shaft.

keep up the good work

I would also like to hear this and see RWHP #'s for this one. With the smaller VVT-1 cam can the heads be milled to achieve between 10.7-10.9 compression without running into PTV issues?
