It has in the past and recently (and I hope I speak for Cartek) we have been working very well with each other and we highly respect the guys at Cartek and its not right to be posting anything to do with our products in one of their threads. I guess I will own the guys there lunch now.

 

very respectable.

 

Good luck Anthony.

 

I did that on my SS. It was nice knowing that the car would pass visual inspection and I knew with a little effort I could pass the tail pipe in a pinch too.

The exhaust restriction does effectively limit the size (i.e. overlap) that you can run. I'd bet a 224/232 114 112 would probably make for a very good cam on stock manifolds. Reasonable DCR and should pull strongly to 6500.

Look up a member 11secondGP. He was doing a cam no headers in his LS3. I think he hit 440 RWHP.

Good luck in your quest. Since Cartek will have a dog in this fight, I'm sure they will go all out.

 

...cam only means cam and it's required installation kit only.

 

And I take it that "heads and cam" means that ONLY the heads and cam have been changed as well right?
And a "turbo car", well that means they just hooked up a turbo to one of the manifolds, no intercooler, no fuel system mods, no waste gates, just that turbo.

 

In recent times I have noticed nothing but maturity and professionalism from the tuners on this board and troublemakers on this thread not-with-standing, Chris gets a Kudos for his attitude in the here and now.

Good luck to the Cartek crew with the project and good luck to Ed's future runs as he realizes the better ET's the car is capable of, as indicated by the trap speeds proving its legit power level.

Off topic, I wish all of you could see the mountain views I have here in Colorado on my vacation. I've never seen this before and feel I was cheated living on the flatlands in America.

 

 

I know Cartek believes in track results versus power numbers, but I am curious what their cam-only ballpark RWHP would be for an LS3, assuming of course LTs and CAI, and what the intake duration would look like (224-ish, or more).

 

Well, they believe in both. The track results over dyno numbers thing is based on seeing SO MANY high dynoing cars not back those dyno numbers up at the track which often means one (or all) of three things.
1) That either the dyno numbers are false (dyno sensor/correction factor manipulation etc.)
2) That the parts combos weren't the best choices.
3) That the tuning parameters changed were done strictly to make the car look great only on the dyno with too little thought to how it will react on the road/track.
Properly matched parts (cams, heads, springs, gearing etc.) and tuning have always been and always will be Cartek's forte/specialty in making these cars run really fast and reliable regardless of what the dyno sheet says.

But just to give you some real numbers, there have been two LS2 automatic cam only Cartek cars recently that have run strong and dyno'd quite respectably as well.
Superstock 1200's and Tony B4's Cartek cammed LS2 automatics both made in the 433 to 441rwhp range. LS2 motors being slightly smaller with a head design that many consider to be lower flowing and of course automatics eat more rwhp than manuals.
It's would be difficult to pin down an exact number at this time but an LS3 manual car like Anthony's will certainly dyno much higher than that with a similar cam only set up.

 

I have a house high up in the Rockies that I haven't been to in several years. Enjoy gods country.

 

I dyno'd an LS3 without headers and cam and made 425whp but Im planning on redynoing after some tuning to see if I can get 430-440 out of it. Just waiting on a Kooks Xpipe to show up and Ill redyno before and after the header install. Should be interesting, I figure the cam only(with headers) range for an LS3 would be 450-510 depending on the cam/tune/other variables... Im just hoping for 460+ though.

 

Well my car is certainly an example of that. At one point, it was doing 493/452 on the dyno, with what the tuner thought was a conservative tune. And it was, at WOT, over 5K RPM. Given the 4.10 gears, that means well over 500 on a 3.42 car. The problem was that the car was detonating a bit in the midrange with good gas on the highways in SoCal, and the problem got really bad on our roadtrip to Utah (in the desert) when I had to put bad gas in it, so that I did not dare give it WOT. Strangely, the car ran beautifully up on the Kaiparowitz Plateau, which is 5-7K ft. elevation. Now, we have what a tuner would call an ultra-conservative tune, which to me means I can hammer it all day long on the highway or the track and in hot conditions without hearing a hint of detonation. In other words, it is a stock-reliability tune.

We are now at 484/439 with this tune.

 

Saturday we will be at englishtown for cc my last run with boltons, Then it goes to cartek i will post all the #'s when finished.

 

good luck

 

Thanks Dennis.

 

You might get it for a few months.........but when I get mine back from LG....yes I broke the trany.......and the weather turns cool again.....I expect to be number one.......but good luck in the meantime....

 

Hmm, this is gettin' good.

 

Sorry to hear that you broke the trans.

Just biding my time

I have the little engine(LS2)that could attitude.

 

Perhaps you'd like to get some gears in that beast of yours and maybe throw your hat into the cam only record ring?
