2010 LS3 Camaro goes 402/410 on the dyno with AR Longtubes, stock catback & air box Finished up the header install last week, retuned, and strapped this one down. Mods on the car:
-AR 1 7/8 Longtube headers, no cats
-Spartan Tune
-Stock Airbox
-Stock Catback
Side notes. The 398rwhp # is what the car makes on the STREET, via a street tune. I played with it on the dyno to make the 402/410 with some more timing, but it does NOT like that tune on the street. Timing tables for the street are completely stock @ 18-20 degrees. A/F is ~12.5-12.7.
On another note, AR's headers are top notch. I was skeptical of using them before due to the high price tag, but they're worth EVERY penny. Also thanks again to Ron @ Vengeance for hooking us up with a great deal on the headers.
In 4 weeks we'll be installing an Engine Power Systems camshaft w/ appropriate valvetrain hardware, SLP underdrive pulley, custom CAI, and ported TB.
Now to the #'s.....

Those Ls3's certainly put down the torque ! Good job and its nice to hear someone say that about what a motor likes on the dyno vs the street. Not everyone realizes just because it runs good on the dyno, doesn't mean it will drive well on the street.
Great job, looking fwd to seeing the cam and pully with retune results. How big of a cam are we talking, or still spec'ing it out ?

Thanks again Ron.
Doug, I'm going to put the specs for this motor in Geoff's hands over @ EPS. I like his style of doing things, and he's done real well as of late with him new lobe designs. This car will be built as "daily driver" friendly, so it won't be anything too nasty. I'm assuming/hoping with a camshaft, pulley, CAI, and ported TB we'll pick up at least 70rwhp.

Thanks for sharing. Certainly seems like the trend is getting away from the PEAK power cams, and using cams that make a bit less up top, but make up for it under the curve all day long.
How's the customer like the car post install and retune? I'm sure he's happy, I know I would be considering the limited mods and huge gain.

After the headers/street tune, you probably couldn't have knocked Daniel's (the owner) **** eating grin off with a sledge hammer. This is his first "muscle" car, so he's really enjoying it. It's always nice to do something to someones car that makes them smile like that.
I need to get another LSX so I can smile like that about my own **** again.

Well if he's this happy with 400/400 or so, whats he going to do the first time he goes to pass on the Expressway after you do the cam and pully (Another 70 rwhp) !! He'll definately have a permagrin. Something about the way the power just builds and the car explodes forward. Great job, how about some video after the cam is installed ?

There's only so many ways you can make the same CAI. I personally don't believe there's $400-500 worth of magic in any of them. Definitely one of the biggest rip offs (price wise) in the aftermarket parts industry right now are the 2010 CAI's.
We'll be making our own.

Just search LMR CAI and dyno day and it should pop right up. If you don't find it, let me know and I'll do some digging. Given your smarts and board savvy, you should pop right to it. 
And for the record everyone, you only "save money" if your time is worth zero. I know my time isn't worth nothing, is yours? Multiply your time to build by your hourly labor rate, add material cost and shipping, now you get the real cost. It always blows my mind when someone in business missed that point. Besides, there are some particular details that are important in building a CAI, especially if you want it to work with the factory tune/be easier to tune. Why reinvent the wheel? There are a couple of good units out there, they're all in the 300-400 range - I don't see what the big deal is. Where else you going to spend that little money and pick up 10-20rwhp (if not more)?

I'm just still amazed that bolt on, tuned LS3 M6 Camaros put out 400+/400+ all day long, regardless of dyno. My LS3 put down 465/444 through a crappy catback, those duals have got to help output a ton. Anywho, rock on and share the results after the CAI is on.
