11's w/ stock N/A M6 LS1--no heads, cam, or weight reduction? Just curious to know if it is possible to run in the 11's with a stock M6 LS1--no heads, cam, or weight reduction. My car has run a best of 12.43 @ 114.23 on drag radials. I just broke some teeth on the spider gears in the stock 10-bolt. A Moser 9" w/ 4.11's gears is currently being installed. After the rearend goes in, I will run the car with slicks. When I ran the 12.43, I launched at roughly 2500-3000 rpm. With the slicks, I hope to launch somewhere between 4500-5000 rpm. Do you guys think I will see 11's. I think that I can do it. Let me know what you think? Thanks.

Well, you are going to loose some rwhp with the 9inch. But I see that your 60ft was 1.9 If you can lauch hard and get some lca and phr and some good suspension. You can get a 1.5 and with the added weight of the 9inch you will be very close with you goal.

I was running some 12.40s in my car last year, stock internal with the stock 3.42s in the 10 bolt. It broke after 10 or so passes leaving at 3500 and cutting some 1.95 short times. After that I bought a Moser 9" w/4.56s. Bumped up my rev limiter to 6200 I think it was, so I could leave at 6000. Then I went to track and it took me a couple of times, but I wound up busting off a couple of 11.9xs with the car leaving at 6000. It was cutting some 1.7xs short times. My car was full weight at the time except for prostars, no backseat/seatbelts, and spare tire/jack was gone.
So it is possible, but you have to leave hard and get a good 60ft time.

Thanks for the replies. They say that for every .1 shaved off the 60-ft time, you save .15 on the ET. If this is correct, if I can pull 1.60 on my 60-ft, then that should translate into .45 savings in the 1/4 based on the 1.90 60-ft with the DR's. That should put me in the 11's. FWIW, my 12.43 was on brand new drag radials which I did not heat cycle or do a burnout in. I also launched very low on the DR's. So I think that I never maximized my potential with the DR's, so there is a lot of room left for improvement with the slicks. Keep the replies coming guys.

I can see it. There is an 05 GTO A4 doing that right now on ls1gto.com.
11.89 @ 115 I believe is the time trap. All he has is full exhuast, CAI, tuning, convertor, 3.91 gear and a liitle weight reduction.

w/ weight reduction yes it can be done.
that gto had his rear seats out they weigh close to 100lbs along w/ having the gas tank support out which weighs about 60lbs.
your not full weight if you have welds on and your seats out.
full weight is stock size tires in the front,back seats etc.
-brandon
if your full weight it will be very hard to hit 11.99 but w/ weight reduction it can be done.

I plan on doing in the near future is a dyno tune so I can recalibrate the speedo and make sure she's not running too lean. Even without the tune, I think that I can still get into the 11's with slicks.

not very hard if you car weighs around 3250-3300, if i had headers and a gear, which i would estimate would had 20 hp i would have went a 11.52 at my weight which is 3365, so add 150 lbs and my time is 11.67 so yeah i think it is very possible, obviously the da was -950 which about every 800ft is a tenth so with about 1000 da i would still be in the 11's....long story short...yes you definitely have the MPH for 11's just need traction...

I think it is possible to run a high eleven but I agree with Brandon that it will be hard. It will most likely take several trips to the track to get everything tuned for traction and make adjustments as necessary. I would recommend the hoosier 26.9.15 slick because it is light weight and is a good tire for a full bolt-on car. I would watch the weather to get optimum weather to assist you in your quest. For some reason I generally run my best time late in the evening. Don't be afraid to take out your passenger seat and entire back seats for a littel weight reduction and very low amount of gas in tank. Therefore find the best weather, maximum traction with what you have, slicks, and a little weight reduction, and you can run an eleven. good luck in your quest.

I'll be impressed if you make it. Heck, I'm impressed already. My car is similar to yours but I have LS6 heads and a (small) cam. I am now installing longtubes and hope to get down to 12.2 or so but I don't expect 11s.

That's going to be tough with a 6 speed. (A few have posted about doing it with automatics, but that's not what you asked about.) I've got a C5 that weighs in ~3250# race weight. (Lighter than most F-bodies, but in your ballpark.) I went 12.311 @ 111.34 last night. Mods are Vararam, home ported throttle body & MAF, and MT drag radials. Short time was only 1.798, so I think there's a little more in it. I'm not real aggressive on the launch because I'm still on the stock original clutch (with 60k miles) and stock output shafts in rear. I posted a similar question a little while ago to the Corvette crowd over here http://forums.corvetteforum.com/show....php?t=1534295
The automatic guys have it easier with stall and gears, but I'm hoping to get there with my 6 speed. I'll be adding headers, exhaust, intake manifold and EWP soon.
