Not 8 tenths difference, please read: 0.3 - 0.4 sec = 3 to 4 tenths.

I did read, read mine please. I said that used drs and cai =.8 tenths. I guess I didn't realize a miracle happened and a dr only LS3 hit 11.95 before the honker was installed. If you're saying the CH shaved .3, then the used drs shaved .5 . OK. Helluva impressive et gain overall and would like to see this feat duplicated (at least within .1 on car with same and only mods). If you got this kinda response from an LS3, why not get a stock LS2, add the honker and same used drs and lets see what the gains are there. Even if the LS2 isn't as fast, the gains should be similar in value. Anyway, if you made that run with just those mods, I have to hand it to you,great run and impressive times. It's gonna make alot of people second guess buying a Z06.

Typical timeslip from Oct 10 session, with stock intake configuration:

Thanks for posting. That actually does show something interesting. Comparing to the earlier slip with the Honker, you picked up 3.5mph at the 1/8th mile mark, but slightly less than 3mph at the 1/4 mile mark. Not sure what to make of that yet, but it's the one thing that struck me right away - while the 60' times are about the same, most of the difference in times are before the 1/8th mile mark. After that, there is no real improvement.

Actually, the 11.95 was typical of the e.t.'s with the stock intake. The engineers made several passes in each configuration. Pretty impressive especially considering the car had less than 300 miles on the odometer.

The gains are similar with Honker equipped stock LS2's, i.e., 2 to 3 tenths quicker than stock. We performed that testing during LS2 Honker development in 2004-2005. I would submit that the LS3's additional displacement (6.2L vs 6.0L), significantly better heads and camshaft produce slightly more of a gain with this particular intake modification.

All I'm gonna say is ATCO, that freakin track is well known to produce very fast times. Go somewhere else and that 118 trap drops considerably.

There is a reason for all these crazy times some people run on the forums, no suprise it always seems to come from a NJ track. So while it's all amazing to see an LS3 run mid 11's, equip an LS2 with similar power and traction and you'll also have a mid 11 car that day.

If I remember correctly from the slips posted on your LS2 testing, the runs were done at Lebanon Valley Dragway NY, which is higher in elevation then Atco and a much slower track. Would've been interesting to see an apples to apples comparison of the LS3 honker at LVD.

Has the car been dyno'd?

It's gonna make alot of people second guess buying a Z06.

Second guess buying a Z06??? Shoot, on the contrary. $500.00 and a set of used drag radials??? These Callaway results are nothing short of remarkable.

Car didn't even have to go through a relearn. Didn't even have to drive it around for a little bit.

They ran it at 6:47pm, put in the cut shroud and Honker, and by 9:13 PM it had whacked off 4 tenths off it's time. I want one of these for my Z06.

If a set of drag radials and a Callaway Honker in an '08 C6 can cut the GM quarter mile spec from 12.4 all the way down to 11.5 for a total improvement of 9 tenths...... then the same mods ought to be able to take 9 tenths off the GM Z06 quarter mile spec of 11.7, bringing it down to 10.8.

After all, a Z06 is lighter, so thats not an unrealistic expectation in light of the near 100 lb weight penalty of an '08 Z51 C6 vs an '06 or '07 Z06. An '08 coupe is 87 lbs heavier than an 06 Z06 and 85 lbs heavier than an '07 Z06

Hell, if a Z06 owner gets his hands on one of these and a set of drag radials, he should be running 10.8s right away.

In fact, bone stock Z06s on drag radials have run 11 flat all the way down to 10.8. Another 4 tenths off that with the Honker, which is what it is said to be capable of giving, would put those cars at 10.6 and 10.4.

A set of headers and you're into the 9s. And a heads and cam, into the 8s.

But for now, I'd just settle for 10.5.

Where do I send my $500.00??? No tune needed for the Callaway either????? Shoot, thats all I need to hear. I'm getting ready to put one of these bad boys on my Z06 now.

***** Seriously though, lest anyone think otherwise, a C6 Z06, modded similarly with just a CAI and drag radials, has run 10.8.

http://forums.corvetteforum.com/show....php?t=1565013

That one had a CAI and drag radials, just like Callaway's '08 C6. And a mail order tune.

10.892 @129.43 mph..... Thats a long way from 11.562 @118.82.

I don't think many Z06 owners will be second guessing their purchasing decision based on Callaway's results.

Please update my spot:

Before I get into the story here are my mods:

2005 C6 A4
Nittos Invos (Made by God!)
1 7/8 Kooks headers - no cats
Vararam intake
Cam - Mild..very mild
Dual Dry Shot 125
EFI Live tuned by Me!

Track:

Houston Raceway Park
Little Humidity
73 degrees....nice cool night

On to the story:

So my boss wanted to visit the track and run his Shelby GT and as most of you know I am a race junky and of course say "hell yeah". I have a full bottle and running on some nitto invos (street tires not DR's) plus the weather was great.

I approach the box, go around the water and heat up my nittos until i see white smoke. I let up on the pedal and let the car take itself up the the staging beams. I was in the left lane and a blazer SS in the right. One beam....two beam....bring rpms up to 1100 (stock stall) and 1..2...3...floor it! The Trailblazer SS jumps out a full 1.5 cars (AWD FTW). I look over and was like WTF!!!! Nitrous activates at 2100 rpm and the car slams me in the seat, this never happens on the street. That blazer no longer looks impressive and in fact seems as if he hit the brakes...well he didnt, it was just me going that much faster.

The car screams down the quarter and I notice my injectors must be maxed out because on the top end i notice my AF ratio creep up a little. I stay in it as its not really a big deal and trigger the 1/4 lights. I tried to look over as I crossed but couldnt see the board. Run felt good but didnt know how good.

I pull up the old lady in the booth at the end of the track to get my ticket. She looks at my car...looks at the ticket..she looks in the car....looks at the ticket...she looks at me and says "Pull over there and wait". ****, I'm thinking maybe something happened to my car and i put liquid on the track.

Some track guy walks over with my slip...radios the tech guys up front and describes my car. He hands over the slip and this is what i see.

R/T.........663
60".........1.821
330.........4.881
1/8.........7.356
MPH........99.15
1000......9.505
1/4........11.316
MPH.......123.93

I now know why he pulled me over. No more track time for me until I get a cage!!! Hell yeah!!!! I can live with that!!!! I tell the guy, I am leaving so dont worry about me trying to run the quarter again and he said alright.

In my mind this is a 10 second car with drag radials. Once i get injectors I am going to slap on MT's up to a 150 dry shot.

BTW...this was my third run. Because I tuned the car initially in the hot weather, this really cool night messed with my tune and I was running lean the first two runs but still managed 11.7's on both with 1.99 60's and highest trap being 124.22. I still have a lot left in the car especially on the timing side. Running a measly 19 degrees.

Track:

Houston Raceway Park
Little Humidity
73 degrees....nice cool night

On to the story:

So my boss wanted to visit the track and run his Shelby GT and as most of you know I am a race junky and of course say "hell yeah". I have a full bottle and running on some nitto invos (street tires not DR's) plus the weather was great.

I approach the box, go around the water and heat up my nittos until i see white smoke. I let up on the pedal and let the car take itself up the the staging beams. I was in the left lane and a blazer SS in the right. One beam....two beam....bring rpms up to 1100 (stock stall) and 1..2...3...floor it! The Trailblazer SS jumps out a full 1.5 cars (AWD FTW). I look over and was like WTF!!!! Nitrous activates at 2100 rpm and the car slams me in the seat, this never happens on the street. That blazer no longer looks impressive and in fact seems as if he hit the brakes...well he didnt, it was just me going that much faster.

The car screams down the quarter and I notice my injectors must be maxed out because on the top end i notice my AF ratio creep up a little. I stay in it as its not really a big deal and trigger the 1/4 lights. I tried to look over as I crossed but couldnt see the board. Run felt good but didnt know how good.

I pull up the old lady in the booth at the end of the track to get my ticket. She looks at my car...looks at the ticket..she looks in the car....looks at the ticket...she looks at me and says "Pull over there and wait". ****, I'm thinking maybe something happened to my car and i put liquid on the track.

Some track guy walks over with my slip...radios the tech guys up front and describes my car. He hands over the slip and this is what i see.

R/T.........663
60".........1.821
330.........4.881
1/8.........7.356
MPH........99.15
1000......9.505
1/4........11.316
MPH.......123.93

I now know why he pulled me over. No more track time for me until I get a cage!!! Hell yeah!!!! I can live with that!!!! I tell the guy, I am leaving so dont worry about me trying to run the quarter again and he said alright.

In my mind this is a 10 second car with drag radials. Once i get injectors I am going to slap on MT's up to a 150 dry shot.

BTW...this was my third run. Because I tuned the car initially in the hot weather, this really cool night messed with my tune and I was running lean the first two runs but still managed 11.7's on both with 1.99 60's and highest trap being 124.22. I still have a lot left in the car especially on the timing side. Running a measly 19 degrees.
Great run ...... hey at least the officials were nice when they asked you to leave

Tommy D...I got a question on these rankings regarding the 2008's with the NPP +6hp exhaust option.

If one has the 2008 NPP Exhaust OPTION (extra 6 hp), I dont think that should be STOCK. After all, if I put only a Corsa Sport on my otherwise 2007 stock car, what is the difference? Why should my 2007 stock with Corsa Sport only add-on be put in External Engine Mods category and the NPP option is not? I think NPP should be put in External Engine mod category, OR, Corsa Sport (or Borla, etc,) ONLY should now be placed in the Stock category.

Default A Day At The Races

Test and Tune started at Thompson Drag Raceway at 10:30 am this morning. Temp was 48 degrees with a 10-12mph wind behind me. This was a different track than where I went to in June (13.3's mostly in 80+ degree heat at Summitt Park Raceway). Since then, added a 160 stat and opened the shroud to my '07 A6 with only Corsa Sport exhaust added to stock. Tire pressures now at 42 front, 28 rear. Only 20 cars were there!!! so no waiting at all in line and my water temps never rose over 185. My first run was a bitter disappointment of 13.37-112.19mph but I screwed up (bogged down) on launch (2.219). At this track, I could spin/burn good. My second run was 12.817 (2.069) at 110.172 starting at 1200 rpm. Third run @1200 rpm launch was 12.786 (2.063) at 113.052 and BINGO fourth run (launched at idle rpm) was 12.695 (1.986) at 113.077 mph. I want to thank GLENNHL for his tips and help....could not have done it without him!! Tommy D, you can now add me to the stock?/external engine? category.
