Cam vs. Headers-back...
Which will produce more power:
1. A big, quality cam
2. Headers back to a stock Ti
What kind of HP/TQ gains will they both yeild (roughly)?
Assume everything else is stock, except some type of cold air intake...

Re: Cam vs. Headers-back... (Weedo)
Long tube headers will get you about 15 rwhp assuming you keep the stock cats. About 20 rwhp if you go with high flow cats, and up to 25 rwhp with no cats (off road system).
A cam can net you anywhere from 25 rwhp to well over 50 rwhp, depending on how big you go with it. Although you get to a point where the car's driveability gets compromised, idle problems, etc., and it won't come close to passing emissions if you go with a big, long duration cam.

Re: Cam vs. Headers-back... (stingray454)
So you're saying I should go with a big cam, heads, and headers? I'll tell my wife! 
It just seems like, for the money, slapping in a nice cam is the best bang for the buck. Would seem weird having a big cam with stock headers, but it doesn't seem like too bad of an idea.?.?

Re: Cam vs. Headers-back... (DsC5)
Stano nailed 409 rwhp with his 2003 Z06 and afr heads/no headers and ls1edit.
That would be the way I'd go if I had a 2002 or newer Z06.
2200 for AFR heads..plus installation of heads and ls1edit..
Sell the LS6 heads for 800 and your done.
Thats would be the way to go imho.

That's what, roughly a 60HP gain total? I wonder how much HP the car had before the heads.?.? I was told I'd expect about 25rwhp from just a set of AFR's, everything else stock (except CAI).

Re: Cam vs. Headers-back... (Weedo)
Just one concern, does anyone know at what point you'll stop passing emissions? Will new heads alone, or porting the existing heads do it? How about the LGM G5X-3 cam? Thanks

Re: Cam vs. Headers-back... (George T.)
Emmisions are done here every 4 years or something and are done using the OBDII port rather than the sniffer test from the exhaust. I've heard head/cam cars passing this with no problem. It basically looks for fault codes from what I understand.

So it picked up 24 rwhp from the AFR heads, which is about what you mentioned.

Stano's car dyno'd 385 rwhp with just a Haltech Trap intake and dyno tuning. So his car was a freak to start with. So it picked up 24 rwhp from the AFR heads, which is about what you mentioned.

It's an O4 by the way.
Just so we get this straight, my first tune with the Halltech Trap was 356 rwhp.
The reason I'm so hyped on the tuner at LAPD is because after he got ahold of it, he squeezed 385 rwhp out of it with just the Trap
It's his tuning ability that got the most out of my car
He flashed my computer and started over and after numerous tweaks we ended up with 385 rwhp
Now with the AFR heads he's gotten me over 400rwhp...freak car, I don't think so :flag
I wish Bluerag would chime in, he figures he got 20rwhp alone from the tune
Yeah, it's the tuner in MHO

My baseline power is theoretically higher than your car's as mine did 353 rwhp bone stock with the stock intake and everything, while yours did 356 with the Trap intake (and I KNOW intakes are worth more than 3 rwhp).
Yet your car dyno'd higher than mine at 385 rwhp with just intake and tuning, than my car did with headers, intake, exhaust, and tuning at 380 rwhp.
If it was the tuning, it doesn't make any sense why the same gains couldn't be achieved on my car, especially since my car has headers and yours doesn't.
So something isn't adding up here.

I don't know if its the tuning or not. If it is the tuner, then I got screwed because the same tuner, same shop, 2 days after your car got tuned didn't get anywhere near the same power on my car.

sorry I found my original info on my first dyno with the Halltech Trap only:
First pull-338.80 279.59 tq
Final Pull-354.28 350.00 tq
I was told the reads on the dyno were about 10 hp lower than normal.
Sorry for the confusion

Re: Cam vs. Headers-back... (stano)
I think we all fully understand the fact that Heads, Cam, or Heads/Cam will not fully see the potential without Headers. But the whole point is:
Cam vs. Headers-back
This being the case, I understand that a cam on a bone stock car will put out double the power or more when compared to headers-back on a stock car. Price being equal, the cam would certainly be the way to go. But from the research I've been doing:
Heads: $2600 all said and done (plus you can sell the stock heads
Cam: $2800 all said and done (stock cam is worth about $100)
Headers: $2300 all said and done
Now take your pick...
