Regardless, with those modifications, you'll be happy with how your car performs...

I hope so! Thanks for your reply!

Yea what it does most is smooth out the throttle response and acceleration but only if you have a 102 intake manifold otherwise it would be a waste of money because it doesn't mount up to stock intake manifold. Also you need the pulley kit from katech for the 102 Tb to fit.do not use bbk 102tb it's a peice of junk

I understand fully. I'm not the only one that interpreted post #4 the way I did. I think you're just back-stepping a bit after more than one person gave you a reality check.
But I'm glad that you are not expecting similar results. Enjoy your mods.

I'm not trying to be rude, so please don't take this that way, but you won't break 500whp with a ls7 cam and gmpp heads. With a different cam, yes, you could see over 500whp, but the ls7 cam (211/230 120lsa <.600 lift cam) is just not going to get you there. If your goal is over 500whp, call Kip at Cam Motion and he'll get you setup with a properly spec'd cam for your application.

I'd say you're looking at around 460whp. The car should have good driveability however.

[1sick_eg]

Also, if there is a guy claiming to have made 527whp with a 376 with heads and a ls7 cam, he is a liar, or has put the car on a serious number fudging dyno.

Oh, that and the catch can right?

Not true at all.

If you're increasing the airflow in/out, you can't keep the same restrictive piping from the factory. One of the biggest problems with the factory intake is the muffler, bends, and filter. The factory exhaust manifolds may be rated to xyz power number, but that doesn't mean they will make the best power plain and simple. On a head/cam ls3, longtube headers will add anywhere from 40-60whp. Yes, that much.

For example, atmospheric pressure is around 100kpa depending on where you live. Ideally on a N/a car, I should see 100kpa from idle to wot. On my car, since I'm still running the factory intake manifold, after 4200rpms I'm falling to as low as 94kpa. That's power being left on the table. You can have the same issue running a restrictive intake. If the heads and cam outflow the intake/IM, you're now under a vacuum.

I'm honestly just curious to see what kind of power increases you'll see, and particularly what the power curve will looks like down low. Your peak gains probably won't be spectacular, but I bet it'll drive really well, like 1_sick_eg mentioned.

So wouldn't this depend on the power goals? If the manufacturer says this cam would get him a 50 hp/40 lb-ft gain with the stock intake & exhaust...

I understand more gains could be had with intake & exhaust modifications... and I understand most of us would like to maximize those gains. However, the person you quoted simply said the stock intake will flow more air than it does with stock head & cam.

Sure, the engine will run, and heck, it'll even have more power. But it will be underwhelming. That's a fact. Period.
I saw an IMMEDIATE improvement after I installed my intake, and a HUGE improvement after I installed my headers, BEFORE I did a tune. First pull on a mustang dyno before the tune was 398rwhp/395rwtq. That is at the very least a 20/20 improvement over bone stock. But yeah, stock intake and exhaust are just fine(sarcasm).

I said what I said and I mean it. What did you pay for the intake and the headers? You just claimed that gained 20/20 which I assume is 20 HP and 20 ft-lb torque. What did it do to your lap times / ET's? Was that bill about $1000? Maybe it is less. I am asking and not trying to be sarcastic, just trying to make a point. A gain of 20 HP and 20 ft-lb is not HUGE. It is not worth even getting out my tools for. If you are happy with it, thats great, and I appreciate your honesty (not claiming 50 HP from a CAI and headers). What did you gain from the heads and cam? What did you gain from the tune? I think we just have two different definitions for the value of HP.

What I would love to see, and I doubt it will be done (except maybe by me once my warranty is gone) is home much HP can be gained by a tune only on a stock LS3, and then how much more was gained with the addition of the CAI and the headers.

Of course. If that's all he wants, then that's fine. I do agree with the guy I quoted to an extent, that some people make a bigger deal out of which CAI is best.

I don't doubt that you find oil in your catch can. If that makes you feel better, than it was a good purchase for you. I can tell you feel that is very important.

You're looking around a 20whp difference between stock tuned/bolt-on tuned. Cleaning up the fueling and timing on most ls3's and you're looking at picking up 20whp. Another 20-30whp with headers/intake/retune. On average you should be around 400-410whp stock with a tune, and 425-440whp with bolt-ons and a tune.

Mind telling me why you wouldn't want to run a catch can?
