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.

I'm a currently running a polluter cam. I am more than happy with my setup, but If I could do it all over again I would have probably went with a PatrickG spec'd cam with EPS lobes. Do a search and you will see crazy dyno\track times on what guys are putting down with these cams.

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.

see with the T-rex mine dynoed at 463/411. I wanna find something thats good under tha curve but can still produce satisfying numbers.

what are the specs on each? I see you dont have gears so i would say get the smaller of the two.

Here are the specs on the polluter. I'm pretty sure texas speed's website has the specs on the Trex.

XER lobes .610/.612 lift , 242/244 duration 112lsa.

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 decided to have Jim over at speedinc tune mine. I also opted for speed density. This cam with my sd tune is very streetable. There is some slight bucking when the car is cold, but once the motor warms up it runs extremely smooth. No drive-ability issues at all. I'm running a 4.10 gear, with a 26" mickey thompson DR.... wish I was running 28's though.

This, i would be prepared to flycut your pistons with those cams. I am not too sure those worked heads will clear such large cams.

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.

@5.3LJimmy
So would the the Raptr cam really be more like what you are talking about for more low end grunt and good top end HP #s? 236/242 - .615/.615 - 111 lsa

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.

Well said... All you have to do is look at the "Fastest Cam Only" list and see what mods are necessary to make this cam truly shine in a car.
