LS2 V.2 Polluter 440rwhp/404rwtq "Cam-Only" When we released the V.2 Polluter, it was only offered with one LSA choice. As many of you already know it is the biggest cam we offer that will fit into a stock bottom end with stock heads. The LS1 V.2 Polluter specs out at 239/244 .624"/.595" 112+3, but I now offer the LS2 V.2 Polluter on a 111+2 with the same duration, lift figures and lobe combination. This will give the car a choppier idle, higher peak torque and horsepower, along with lengthening the torque curve throughout the RPM range from the added overlap putting it on a 111LSA gives it.
The car we installed the LS2 V.2 in was a car we had previously tuned back in November when it was just a bolt on car. The cars modifications include a Vararam CAI, ARH 1x7/8" LT headers, ARH ORX, an aftermarket exhaust and now the LS2 V.2 Polluter cam.
We always use Brian Tooley Platinum springs with his tool steel retainers when the vehicle is equipped with stock rocker arms. As you can see, you don't need some spring with 475lbs+ of open pressure to control the valve-train with a large cam.
Here is the final dyno pull. AFR was 12.6-12.7 and timing was 23-27* ramping it in slowly throughout the pull. We tried leaner with less timing, leaner with more timing and it didn't like it and lost power. This is what the car wanted:
Here is a comparison of what the car made with just bolt-ons versus after installing the V.2 Polluter:

This car is what I consider the true definition of cam-only. No FAST intake etc. Just a Vararam CAI, ARH LT headers, ORX, exhaust and the V.2 camshaft.

Thanks!
Thank you Jay. If we can duplicate your 226cc results I'll be a happy man. Should have some more data coming in soon on some more max effort combos.

Here is a good comparison of the two different versions we offer for the V.2 Polluter. Now the LS1 V.2 shown in this graph was installed in a 2002 Trans Am with nothing more than a SLP lid, TSP LT's, TSP TD's, stock LS6 intake/tb and the LS1 V.2(112lsa) camshaft. The LS2 V.2 shown is still the same white C6.

I would have to say that you'd only lose 2-3mpg if even that much on the highway. Probably more so in town, but highway driving I don't think you'd lose much if any.

Your car drives like there is no cam at all!
