how does everyone else compare, my car seems to be a little bit quicker than most with its mods.

basically have cold air, ls6 intake, headers, tune, 4.10s, a cutout, and some suspension(tq arm, panhard, relo brackets)...and some drag radials. i guess i want to give 95% of my thanks to Kieth Mccord's tuning - (he makes the mccord powerplates)

car dynoed at 335 hp and 339 tq before tune of ls6 intake and cutout

That's absolutely amazing for a stock converter. A Yank PT4000 will have you in the 11's for sure if you can maintain traction. It's hard to believe what that conveter did for my heavy car even vs a Yank PY3400. I'm running 7.81 @ 87.25 in the 1/8th @ 3700 pounds with probably less than 300 to the tires. With the extra power you have over me, I'm sure you'll run much better in the 1/8th than I did thereby insuring yourself an 11 second 1/4 mile timeslip. Are you planning on installing a converter any time soon? If so, look into the Yanks.

yes, i'm probably going to down grade to the 3.73's bc im hitting overdrive right before the finish line, atleast 30-40 ft i bet(hard to judge at that speed). then probably go with the tci 3500 bc i can get a deal on them with their flexplate. i hope that goin to the 3.73s keeps me at the 12.49 mark and then the converter does much more.

There are some freak cars out there. When I was driving a ford back in the day, there was this dude in Texas who had a 99 firbird mostly stock. he had a small cam and exaust (unless he was sandbagging) and would run low 8'sin the 1/8th............I was completely floored. Now that I have a full H/C car with bolt ons, I have ran a best of 8.3.

mods are minimal, got a ported TB, cutout, lid, and FTRA, and everything else is stock, here is the link identical to your times pretty much

you're the original owner of the car? and 100% sure there's not a small converter in there or anything? just wondering. but great times

not original owner but 99% sure it does not have a converter, everything was stock when i got it from the orginal owner, the only thing he did was get a K&N filter. It still had the screen in the maf, and factory intake. So i seriously doubt it, wouldn't you get a lid before a whole tc install. I will find out 100% when the yank gets here

Um...I think they are legit numbers. Since I am running similar times without headers. Raise your rev limiter and shift points. You may nock off another 0.1.

DOUBT IT

I ran a 12.539 @ 112.13 with similar mods and street tires. I don't have an LS6 intake yet though... I do have lots of weight reduction. The car weighs 3310 without me in it.

Everyone locally keeps telling me that with a tire and a stall, I'd be in the 11's for sure. I'm planning on a TCI 4000 or Fuddle 3800 and some MT DR's (255/50/16) next year. We shall see what I can do.

Your car weighs 55lbs less than mine and I only have the spare and jack taken out of the car. What else did you do for weight reduction?

DOUBT IT

iTrader: (13)

Back seats and belts out, various little things. I've taken out more things since I weighed it, including cutting all the sound-deadening out of the carpet, taking the tranny sound deadener out, little pieces under the sail panel speakers, sound deadening out of the door panels, various heat shields under the car, I just recently removed the sway-bar, so it probably weighs 45-50 lbs less now. I'm probably under 3500 lbs with me in the car.

FWIW, I weighed it with just the spare out, and it weighed 3660. This was on the local Farmer's Market scale, so it HAS to be accurate. I pay $5 and get a certified weight.

Future weight reduction: AC and condenser, Aftermarket Torque Converter, Lightweight K-Member, Both air-bags and bumper supports.

What was the weather like? DA? My wifes car just has a lid, meter, FRA, and Cutout and with stock converter she's trapping 106 full weight (1/2 tank of gas). How much mph does converters give usually? -Mark

You have a heavy Chevy.

DOUBT IT

Keep in mind that I'm not a light guy myself. These weights were with me in the car, I came up with the 3310 figure by subtracting my 230lb weight from the 3540 weight of the car. If anything, I need to lose some more weight, not the car. I've been trying to teach my 110 lb fiance to drive the car, so I can get another tenth.

It is a fully optioned t-top car though. I wish I would have gotten a stripper.

I used to trap 106 and then after the converter trapped 111. No headers yet.

Mines without me came out to 3365 without the spare and jack. It's a full optioned TTop car as well. The only 2 things I don't have is lumbar support and TCS.

My car is a fully optioned T-Top car too and with only jack and spare removed and a half tank of gas came to 3300 without me in it. The only options I do not have are power passenger seat and disc changer.
