From yesterday's test session:
2008 Coupe, 3LT, Z51, man. trans.
with Callaway Honker Cold Air Induction installed. Otherwise stock.
Used drag radials.
279 miles on odometer at time of run.
11.562 sec @ 118.82 mph
I think this is sufficient to put this run at the top of the "bolt-ons only" list.

I'm sorry....I'm having issues thinking used drag radials and a cai is gonna shave .8 tenths+ off of the ET of an otherwise "stock" car. Not saying you're lying....but saying I'd have to know that car intimately(otherwise,inside and out) before I'd believe it 100%.It'd be very benificial for any dealer to have their product stand alone as the top time holder on the list, being the only mod,save for drs.Thanks for the extended press conference on the track run...no more info than previous imo,just more words.Congrats if your statement and testing is on the level ,you guys have quite the product there if so.

I was just looking at where it placed on the list:
CORVETTEFORUM.COM C6 Corvette ET Rankings
Times are received from all over the country and are not corrected. Because track and weather conditions vary, this list ranking does not, and can not, identify the fastest cars or drivers in any particular order. It only lists the recorded times, regardless of conditions, in order from quickest to slowest. In cases where ET is the same, the higher MPH determines list order.

So an LS3 based C6 with your just CAI on it, runs only 0.28 seconds slower in the quarter mile, than an LS2 based C6 with your $16,695.00 supercharger package on it? Thats if it won't run right with it.

I've tried to make the best comparison I can with his ET/mph/60' vs. my ET/mph/60' and mods. I ran a 12.181 @ 117.54 mph with a 1.974 60' on September 16. I had headers, tuning and stock intake. His Density Altitude was about 400', mine 1800'. Mine corrects to an 11.94 @ 119.88 mph. His 11.51 @ 119.33 mph. Based on mph we are making about the same hp. Can an intake, un-tuned with factory exhaust make as much hp as tuned with headers but still with factory intake? Maybe so.
My factory radials stuck like glue so his DR's don't apply as far as traction. However, each of my rear wheels/tires weighs 61.2 pounds according to my digital bathroom scale. His DR's on a 17" wheel probably some what less. Rotational weight remember.
The difference in the two corrected ET's IMO is all in the 60'. His 1.77 to my 1.97. That's enough to account for the .43 et difference. How he ran a 1.77 60' I don't know but then again the manuals could certainly have more capability than the auto's with factory converter and all this TM.
Tuning is only worth maybe 10/15 hp? And this is assuming my tuning was optimum. Not sure of that either.
I believe his times are accurate for the mods he listed.

The 60' time made that wonder ET happen. 1.7 60' is the magic number. Now, I wonder what the other guys did on their 60' times in their MN6. Because it appears that this LS3 is .3 quicker than the quickest LS2 MN6 bolt on. The mph trap is about the same.

the 17" dr setup is going to be shorter overall than the stock 18" setup...there's the gearing advantage producing the 60ft capability and really making it easier on the driveline getting it out of the hole if done properly (like this obviously was). 400 DA is pretty damn good as well. This looks totally legit to me. Awesome pass

That LS3 is flying. Sort of like comparing a LS1 to a LS6 I'm afraid. We LS2 guys don't stand a chance. They dyno with CAI and headers higher than my car does now with a big G5x3 cam.

Copied from another thread earlier today:
We've been getting several inquiries about the validity of the performance data since I posted the results of our test session yesterday at the dragstrip. Callers are questioning the 0.3 - 0.4 sec improvement from Honker installation only. I thought I should clarify how Callaway arrives at the data we publish.
Callaway engineers have a battery of performance measurement processes available to them to quantify the performance of a given product. Acceleration testing at the dragstrip is only one of them. They also measure airflow on the flowbench and a host of operating parameters on engine and chassis dynamometers. Our engineers also record road course test data, skid pad data, performance data over a predetermined street circuit, etc. The test protocol is selected as a function of the product and how it's used. The cars that the engineers use to perform this testing are prepared only to simulate real world conditions. In some cases, preparation may also include installing parts to remove other variables from affecting test results. For example, specific tires are installed in order to provide consistent dragstrip results, so we can accurately measure the difference in performance of the part itself. However, there's no icing of intake manifolds, or special fuel, or special suspension setups (unless we're testing Callaway suspension, of course), or anything else done to try to get the best possible performance. The engineers are more concerned with eliminating all of the variables that can potentially skew the results one way or the other.
In the case of this test session, the car was specially prepared in that the radiator shroud was modified and the filter base was installed at the factory, then the hole was blocked off for use with the stock intake. This let the engineers change from baseline-stock to Honker-equipped at the race track within a few minutes of making baseline passes. Thus, track and atmospheric conditions would be more consistent during both sets of runs. A-B-A testing had to be performed so they had to revert to the stock air intake after testing the Honker to verify that the improvement was valid. The only other preparation was installing drag radials at the track to provide consistent launches, not possible with stock tires. This particular car only had 275 - 280 miles on the odometer when this testing was performed and was driven to and from the track.
Our performance claim for the LS3 Honker is 0.3 to 0.4 seconds on an otherwise completely stock 2008 Corvette. With yesterday's acceleration testing, several passes were made in each configuration. If the median data is used, the improvement is closer to 0.3 seconds than it is to 0.4 seconds. However, if all of the data from this session is considered, the difference in ET's is, in fact, as much as 0.4 seconds. In Callaway's typically-conservative style, LS3 Honker advertising will specify "approximately 0.3 sec improvement in elapsed time" was recorded.
Sorry for the length of the post, and I don't know whether I convinced anyone that we're not lying about test results, but because of the tone of the questions we received today, I thought we should offer an explanation.
We've been getting several inquiries about the validity of the performance data since I posted the results of our test session yesterday at the dragstrip. Callers are questioning the 0.3 - 0.4 sec improvement from Honker installation only. I thought I should clarify how Callaway arrives at the data we publish.

I understand the time slip as having some advertising on it now. I know that CAI's work. Now I have been pondering ordering a new 08 for a few weeks and this just add's to my many good reason's to order one. My 07 now with 9,000 miles has really come to life. I can see an 08 with CAI, headers, x pipe, high flow cats, good exhaust, 160 tstat and a really good tune break into the 10's after it's broke in and this is with out a cam so would be able to keep the warranty. I guess I just convinced myself to order one today.

That is an interesting explanation. Does this mean you also have the time slips for the runs without the Honker on it? It would be interesting to see the data - such as the 60' time and the trap speed. 3-4/10 is a big difference, and indicates that the car it putting out around 40-50 hp more than stock. Has the car been dyno'd?
Typical timeslip from Oct 10 session, with stock intake configuration:

Stock tuning. We were testing the Honker only and wanted to isolate any other possible variables. Looking at A/F ratio, we're sure there is more power available through modifying PCM calibration.
