Last time I weighed 3195 (car only) with about 1/4 tank. Yesterday I had 1/2 tank or a little more, so I'd guess 3200 or so. I was probably 200 with my heavy winter coat.
I actually left my garage with a light jacket...as I rolled up the windows, went back in for my rarely used winter coat! We florida folks aren't used to the first digit of our temp starting with a 4...49 as I left my house.
Thanks! I am very happy with the 60's. That accelerate into the launch trick that Robz told me about is really the key.
You cannot let your car bog or it's a 1.8 60 foot. On those 1.445 launches the car never went below 4800 RPM throughout the launch process.
I have only 414 tq so I have to spin the engine. I think Z06's and Zr1's with 100+ more ft lbs are able to bog more than me (based on listening to their launches).
I think it's been proven that the stock z06 clutch will not handle a 6700 rpm launch no doubt given the much higher torque of the 427.
I wonder if a Zr1 would handle a 6700 launch with its dual clutch....

It's interesting you say that Joe--as I've had my car bog multiple times and I still get high 1.5 60fts. If I want a low 1.5, I have to keep the rpms up but these Mickeys really stick and cause my rpms to bog down to 3500 on a few of my passes.
You say you only have 414tq though? I thought you made more for some reason. Perhaps its the additional torque that lets me "recover" from the bogged launch?

That's in street trim though right? Surely you're not pushing 3200lbs with the drag pack and no passenger seat.
You Floridian's are something else.
I was working outside in the elements Saturday night into the AM and weather.com showed 7deg's where I was standing.

Melting Slicks
I did a few things.
1) Removed the clutch spring. Well, Joe removed it the first time we met at PBIR, but ya-it's gone.
2) Removed the inspection plates on the bellhousing.
The problem with the corvette hydraulics is that the clutch dust has nowhere to go when it is generated and it then penetrates the vulnerable slave cylinder which is why the fluid turns black.
To assist the clutch dust from exiting, I removed the 2 plastic inspection ports on the lower sides of the bellhousing. I did this a few months ago and my clutch fluid has been remarkably clean ever since. I still do the fluid swap, but what used to take 3 or 4 cycles of clean fluid to 'repair', now only take 1 cycle.
3) My burnouts are now only 3-4 seconds. I used to do longer smokier burnouts to get my Toyo drag radials hot, but these Mickeys don't take much to get them ready.
I also swap the fluid before and after the drag strip as Joe recommended to me awhile ago. I don't expect to get 450+ passes on it, but I'm knocking on the door to the 150+ pass, 70+ of which have been with the cam installed.
Hope that helps.
Big thanks again to Joe for his invaluable information he has so graciously shared with me. Thanks buddy

I do the Ranger method before and after each event religiously since new. The fluid is pretty much always clean, even yesterday evening after those events.
Removed pedal spring as soon as I put in a cam. It was sticking to the floor after the cam (but not with only bolt ons).
I don't think my car has anything plugging the inspection ports on the bell housing, I've seen tracks of clutch dust on the bell housing.
Check out the clutch dust on the video! My buddy said it looks like a pro stocker belching out dust.

Thanks for the info guys... Between you guys, I might have to move to Fla for the killer knowledge you guys have in addition to the great weather! lol Ill look into removing the dust covers!
I be a big part of the problem was the first time the fluid was ever changed was when I got the car with 29k miles! now I do it all the time and removed the spring since last trip to the track... Curious to see if thatll help! But hope to get those covers out before next track day anyway

For me, even if removing the spring didn't do anything for performance, it was such a relief to rid the car of the 'staged' clutch pedal feel. I really disliked the feel of the pedal and much prefer the linear pedal travel.

What's odd is we're both running 128. I compared our two best slips last night, I 60'd you by .06 but you et'd me by .08. It's all in the 1/8, your car pulls mine in the 1/8, I have 4 shifts in the 1/8 vs your 2.
Here's my car nearly empty of fuel and nothing in the cubbies. Yesterday I had 1/2 tank of fuel and my usual assortment in the cubbies - 4 way tire iron, patch kit, small compressor, pliers, screwdriver to take out the clutch spring (Justin I forgot I had that in there when you were up at the track, I really do carry such a screwdriver!), etc.
One time another evening when I weighed the car with drag pack, seat out, etc. but including my assortment of accouterments and 1/4 tank of fuel it was 3195. I didn't snap a pic.

The only other difference in our cars are the gears, right Joe? I make a hair more power, and you have a better gear for the 1/4 mile. My mph is a little higher in the 1/8 than yours, but you obviously come on strong by the big end. I'd love to race heads up one day-talk about a drivers race! 
Oh, and at you having that screwdriver.

That is pretty interesting actually. You are/were my Mr. Miyagi and I learned from your teaching and we run identical times? 
Awesome

Frankly, you have REALLY learned to drive that car and that's all you - you listened to a few tips and ran with it. Not many can get a 1.50 with a stock clutch.

I had a good instructor.
I only need another ~.1 to take the top spot for LS3 internal modification and all the guys ahead of me have way more mods than I do. I just need a nice cool day

Yes you do. You've come a long way in a short period of time. One cool day with good track prep and you'd have it. Sorry I didn't think to call you yesterday, you're a little far, but man, it was wide open track and negative DA in the sunshine all day. That's about as rare as hen's teeth here!

From my experience of swapping from 3.42 to 4.10 gears at my lesser power levels it was worth ~13/7
http://forums.corvetteforum.com/perf...o-results.html
Though the gears are actually worth 2-3 tenths ET, which fwiw turbovic has a non-z51 trans that held him to a 1.61 60'

Gears make it a lot easier to launch truth be known. I found a difference even between 3.90's an 4.10's. But 4.10's with H/C make it a lousy 1/8 mile car due to the extra shift. That was my first "6" second 1/8.
