Some Interesting Power Comparisons
I wanted to see the difference in power between C6s with these combos
1 - STOCK
2 - cai, catback, cai and/or catback
3 - Adding headers with or without tune to any of the above.
I compared the power by using trap speeds gathered from the BIG THREAD.
The results might surprise you.
I took the TOP SEVEN entries in each category and then divided the results by seven.
Here are the results:
STOCK - 114.4
cai & cb (no tunes) - 114.02
headers - 117.09 (tunes allowed)
Then I wanted to compare ets.
To be fair, I did not include ets with DRs, Gears, or stall converters although I allowed them in trap speeds.
Here are the results:
STOCK - 12.41
cai and/or catback - 12.49 (no tunes allowed)
headers - 12.28
So the results stand as follows:
Stock - 12.41@114.44
cai/catback - 12.49@114.02 (no tunes)
headers - 12.28@117.09 (tuning allowed)
This should give a pretty good idea of what these cars are capable of in mildly modified trim on street tires.
What do you think???

I think that because these results aren't corrected for DA that they mean little to nothing.
You asked.

I agree as I saw what a bad weather day did to my times at sea level, but I only had actual times to go with.
Even so, if we assume the best 7 times were in good conditions, it should still match up to corrected times at altitude.

I've noticed this all along.
It is not a HUGE difference, but I would say that a cai is mainly for less maintenance and the catback is mainly for sound.
The STOCK set-up is VERY good, although the exhaust note leaves alot to be desired.
Give Chevy credit, they gave us a great combo right pout of the box.

I hope to get closer to the headers average next weekend.
My C6 A4/3.15 with just a Magnaflow catback went 12.57@110.67
My C6 manual with Corsa Sports and K&N went 12.55@115.85
My C6 manual after headers and a tune went 12.65@115.38

I suspect this was a lot of work and it suprised me a little, at least the the one with the headers, I would have expected better for headers and a tune. I have had a gut feeling that the CAI didn't do a whole lot. People say that the stock filter setup was to restrictive but if you look at it coldly, there are 2 filters and the bridge is as smooth a transition as any aftermarket I have seen.
OBTW, THANK YOU for all the effort you put into this. I kind of hope you continue to update this with more info as it becomes available. The more data points you get, the more validity to the results.
Great work.

Plus I heard fat guys tend to drive cars with headers.

Headers next, no tune.I'm waiting on Howard to get the bugs out of his C6 since he has the ARH. I want to know the real deal on these particular headers. It's just another toss up when it comes to making that decision on headers. Now it the process of elimination, LG, B&B, and Melrose is out for right now. From what I've gathered the Kooks are very good for the 1/4 track.

I would tend to agree with DSOM on this. Unless the cars are run at the same track it it hard to compare results.
My car stock ran 13.04@109
CAI(Vararam), tune and over 100lbs of sound proofing 12.82@111

Please note the times posted are our personal best times, some of them have back up times ( just as real racers do ) and others may be that one time freak great run.
Most of the fastest times posted have been recorded in the late fall & early spring. The list will give the reader a "idea" of what a C6 will run but in no way shape or form can be utilized to make a valid comparasion.

Big difference between posting a DA and posting a corrected ET as your fastest time on our beloved qtr mile time thread.

The video doesnt show the time, but look at the numbers on the car, 102, then check the timeslips!
