T-rex Or Polluter Camshaft? ive been looking at the polluter camshaft lately, and I already have th T-rex just looking to see which one is possibly better, Looking for some people who might have it already!
There are not too many results on the polluter anywhere. You will find about 5 or so if you search but they are all old threads. Most people I have talked to advised me against it... so I got it anyway. From peoples results and reading on here it has BETTER under the curve power for such a large cam. This is not 100% as I have never seen a MS3/MS4/T-Rex/Polluter dyno sheet on the same car with same mods.
As soon as my heads come in I will have my car dyno tuned and post my results. Hoping to have this done in the next couple of weeks.

That being said I put down 463/399 through a m6,dana60,truetrac,4.10 gears, 18x10.5 vette rims, and a steel ds. I just put in a flowmaster merge in my setup so I might have a bit more now. No track times yet, but I should have some early spring. Hope this helps on your decision.

I have the Polluter in my car which is Ls6 Intake/Stock 241's and a forged bottom end. The cam definitly needs a good tuner to make it somewhat streetable. As long as you have the right gear/tire combo, you will have fun with it. The cam did run really well on nitrous as well. I do have some vids posted on here on in-car motor and nitrous passess if your interested. Good luck with whatever you decide.

I had to flycut my setup. I'm running TEA worked Trick Flow 220's...milled to 57.5cc's. I still had a ton of clearance when PTV was measured with clay.
If you already have the Trex swapping to the Polluter will make no difference at all in bottom end power. They both use the same intake duration and likely have near identical valve events other than the exhaust valve closing(depending on ICL and ground in advance). If more bottom and midrange is what you are after then you need to close the intake valve sooner to bring the cylinder pressure up. You need an intake lobe with less duration to accomplish this.
I am running the Trex in my car. That is a cam that you have to be really dedicated to run. 11.5 or better CR, milled heads, 4400+ converter, 4:30,s or better. TR told me unless you are set on making your car run hard on that cam to go with the Raptor instead. Almost same results (give or take 15-20 HP) and you dont have to set the car up so extreme.
