traps seem really high, i ran an 11.98 @116.44mph 1.77 60' with these mods corsa sport, vararam, LG headers with high flow cats, Ported intake and throttle body, and dyno tune(3500 miles). 391rwhp 392rwtq (dynojet) on my 2007.
i did have a nasty headwind, but still 3 mph more thats impressive
Nice runs! 11's easy

If you get a chance read Ranger's posts on launching in his sig and if you come to the Countyline Challenge or the Corvette Challenge I'll show you how I launch. If we're lucky my buddy Robert will be there in his Yellow Z06 and he'll really demonstrate.
You can't dump the clutch or you are sure to leave your rear at the line. I've seen 3 C6's do it at Moroso. One twice. You have to "walk" the clutch letting the clutch out somewhat slowly until you get moving and hooked up then release and floor it. I launch at 4500 for my best results of high 1.6's on a good day and relatively consistent low 1.7's. If I try to launch at 5k I tend to spin and get a 1.9.
I just can't get over that MPH in the 1/8 and 1/4. Is your car a Z51? Do you go through the traps in 3rd or 4th?

That's very strong for a bolt-on C6. I was out there last night in my pewter FRC C5 in the sportsman lanes. My best passes last night were 11.6's with low 1.7 short times. The track was hooking okay, but still about 1/10 off from a good night. Don't know what the DA was, but my mph was a little low as well. You've got easy 11's in that thing under better conditions. You and Joe_G have a couple of fast bolt-on C6's

I have the same mods with an A4 car, run 11.80's at only 112. I hope to better than now with the 3:42 I put in yesterday. Get some sticky tires and you will be in the 11's no problem. My car made 366 to the wheels after the tune and runs low 1.7 sixty foot times.

sorry these runs were made on c5 17inch z06 wheels with mickey T's car was redynoed on different dyno at 370 seemed low to me but whatever thats what it read.
Started launching at around 3500 and it would jump out and bog so i went up to 4k and still bogged i didnt want to go any higher because i figured id be pushing the limits of the rear. Tires were set at 21psi

FRC rob whats done to that thing i watched every run of yours that thing amazes me i went and looked under the hood when you had it poped i thought it was supercharged for sure but i didnt see anything but i thought i kept hearing one.
My car is not a Z51 its just a base vette weighed in at 3116
it was first time out on the drags and every run i improved i think if i could have got one more run i would had that 11sec pass

To shawndfw the trans am was my first car i loved that thing. It was sure better than buying a mustang. I got it to go mid 12s in high school with just bolt ons. And then put the 150 shot on it every kid in the world thought it was the sickest car ever. Now at 20 i sold it and bought my first vette and will probably own them till i die.

Then, go to some Challenge races and pick the brains of of Joe_G and Robert Payton (Retrotech)...they're two of our local Challenge racers who seem to do the best jobs at launching 6 speed cars on drag radials. I've been following their advice and I'm getting better

trust me, the cooler air temp is of much greater importance. there are excellent prepped tracks in the northeast, and when you get one of those 30.60 highs over you and 45-50 degree weather, you're talking big negative DA and maximum power.
the trick is to catch this weather scenario, and be out during the day in sunlight. that will heat the track sufficiently and then it's on, record type capability, especially for a NA car. driver just needs to execute

I was simply pointing out that for every air quality advantage/benefit there are also disadvantages/negatives to contend with that other climates might not have to and I guess we just get a little tired of hearing that we get the times we do ONLY because of the better air. If that were as undeniably true (as some here believe) then I wouldn't have gone quicker/faster at -900 feet than I did at -1600 last year in the exact same car.

True, but that type of air combo (ie: such a high barometer with such low temps WHILE a track is open/dry) is still quite rare, even up here...while it's true that south Florida almost never sees that kind of air it's not totally unheard of to see some seriously negative DAs in Houston or even Louisiana.

I'm not ******* anyones times. And I'm certainly not saying houston or even florida will never see those conditions, because they will. I have to deal with that "weather" card being played against me and my times on frequent basis, so I know exactly where you are coming from. My only point was, in my opinion, the NE tends to see a few more instances of these type conditions than you will in the south. And of course that weather guarantees nothing, you could very well run faster in slightly worse air. No queston about that. But the key is still seeing anywhere from +100 feet to the big negative days. I think there is some diminishing returns from huge negative air, but on the flipside, I don't see many records coming from +1700 either. It takes some at least decent air to make a great run, and houston/fl is shut out of that scenario for a span of many months. Zero hope of a cool front passing by. And obviously, at some point, the NE gets shut out due to too cold of weather and closed tracks all together.
so, the perfect arrangement is live in houston Dec - Mar and head back to the NE Apr - Nov.

The MPH fall when you hook better. Shorter 60's are inversely proportional to the trap speeds. He will run 11.8 @117 or so with a 1.7 60'.
