Hoping for 11's with New 410's

![Default](https://ls1tech.com/forums/images/icons/icon1.gif)
So i ran it last night after doing the rear over with 410's from the 342's and i didnt do better My 60ft dropped to a 1.786 which isnt bad its prob got more in it which will help just its in a 10 bolt with a 6 speed so i dont go to crazy with it. But i figured the new gears would get me to the 11's and doesnt seem possible with this Cam only set up. Maybe some weight reduction? Traction isnt the issue just seems not enough power to do it. I could buy a new throttle body maybe just to add a little more hp. But anyways heres the slips from the Old rear end on the LEFT and the new gears and rear on the RIGHT. Think i can get 11's or is that not going to happen with this set up? Maybe some ideas to get this car going quicker. Video is below also. Thanks

Also here's the dyno sheet where my torque is falling off the map after 5100 so i should maybe shift early

Very strange your 60' ET times are quicker, but your mph is slower and your other ET's are only marginally faster.. just with that improvement of your 60' you should have been very close to running an 11??? something somewhere is not jiving?? like shift points? tire size? you really need to look at a couple logs while at the track to find out whats happening?? Maybe your getting some knock retard?? look over the graphs closely and i bet you find something out of place.. Good luck man..

x2. You should be trapping 120mph + with 423rwhp (I trap 124+ with 413rwhp). 4.10 should actually be to much gear if your on a 26" tire. What rpm are you turning? What's your car weight?

The da was 2500 which sucks. I definitely need to get something to log the runs what's a good unit to buy ? What's strange is i made 394rwhp when it got tuned then i dynoed it later it made 423 but even so if it was 394 it should be faster than what it is. The tires I have are MT et streets 255 60 16s they definitely hook well. But i will change my shift points and try at like 6500 see if that helps. Also the car is full weight also with a tool box Jack and a bunch of other weight haha this wednesday I will remove a bunch of ****. Rear seat, tire and ill find other stuff.

One thing to look at is you ran in june (low 90's weather) and than the second time you ran was in aug (100+ weather). Go back when it starts to cool off again at the end of september and I bet it starts running alot faster again.

OP i'm just going to say it like I see it at my local track that I goto.
I have yet to see a M6 cam only LS1 Fbody or even cam and intake only M6LS1 Fbody run 11's in June,,July,,or August at the track I goto.
I feel forums members 1/4et's are so far over exaggerated that in the parking lot and staging lanes at the track I goto NO one has there hoods up ,because they don't want to be embarresed by there mid to high 12second ET's with H/C/I they just keep there hoods down.
Actually in one of the recent GMhightech issues one of the editors even mentioned this same issue about an LSX event that was free for anyone that wanted to race there cars that a sponser was paying for everyones admission into the race. The editor said that there was more LS cars in the parking lot that Paid to see the races than there was on the track that got to enter for free.
I agree with this editor that mostly likely half the cars in the parking lot that chose not to race didn't want there real ET times to be revealed because that would reveal there Forum typed over exaggerated 1/4 mile ET times.
The last two LS1 cars that I witness run a 11second pass was a C5 M6 Z06 with nitrous and DR's he ran a 11.8 at 118mph and a 2000 camaro with cam ,,stalled A4 and nitrous run a 11.9 at 112mph.
So OP wile your times may seem dissapointing to you based on everyone elses FORUM ET's ,,but from what I have seen at my local track over the years your car is running along with most of the cam and intake LS1 cars that I see at my local track.
Also I have 3.42's right now and I have been debating going with 4.11 gears,,,as of right now I end the 1/4 at the top of 3rd gear and have been debating if I go with 4.11's that will cause me to have to shift into 4th gear that if having to make that extra shift into 4th gear will cause me to run around the same time as I already am with the 3.42gears,,because everytime we shift we are loosing valuable time in the 1/4mile.
Lastly if it makes you feel any better my best time so far and my car weighs almost 3700lbs with me int it and a 2600DA was 12.34 at 115.98mph with a 2.04 60ft bouncing off the rev limiter just before the end of the 1/4mile in 3rd gear.
My rev limiter is set at 6500rpm along with i'm having to shift early into 2nd and 3rd gear to stay off the rev limiter my 1/8 mile MPH was 94.94mph.
So i'm raising the rev limiter to 7000rpm and will be shifting into 2nd and 3rd gear at 6500-6700rpm I think I can run atleast a 11.9 with my stock lowered suspension and Toyo DR's with my factory 3.42 gears,,3700lbs and a 2.04 60ft.
I have yet to see a M6 cam only LS1 Fbody or even cam and intake only M6LS1 Fbody run 11's in June,,July,,or August at the track I goto.

Are you a ford guy or something??? Ive seen many cam and head ls1's go low 11's Grandted they are autos but they still run low 11's. And a nitrous z06 running that time is god awful! i had a stock z06 with Drag radials and i ran a 12.5 it was stock even with the stock exhaust. We all know on here the LS motors have insane potential every auto has proved this point stock automatic cars running 12's and with a stall and some small work getting high 11's.

I have to add to 1of625's statement. Granted I don't go to the track every weekend but when I do I don't see many LS1 cars running 11's. I've beaten so many with my SI LT1 it's sad. One guy was really upset when I opened my hood and showed him. He had a 383 H/C/I dynoed tuned and was 3/10's slower than me. It just goes to show you there's more to buying parts and bolting them on to go fast.

If you want to be a smart azz↑↑↑↑ I can be one to,,because you just spent money on a factory 10bolt buying 4.11 gears to run the same exact time that you ran with 3.42gears which in the end equals fail
especially when the 10bolt leaves you stranded at the track.
You run a 1.786 60ft in 66dgree weather with a DA of 1602 and you still couldn't get into the 11's even with 4.11gears.
I could only dream of 66degree weather and a 1602DA in August at my local track,,,hell my car would have ran a 11second pass bouncing off the rev limiter with a 2.0+ 60ft with 3.42 gears with Toyo DR's if the DA was 1602 at my local track.
I can go on and on ,,but the fact still remains if you would have raced your car on the same day same time August 26th 2011 at 7.35pm at my local drag strip it was 87.8degrees outside with a DA of 3130 you would have ran a 12.7-12.8 based on the time slips you posted at the start of this page.
Am I starting to make since to you now??? because I can't make my point any clearer than what I just wrote above↑↑↑ the facts and reasons are there.
So agian you and others can make all the remarks you want about my first reply to this thread ,,,but agian as noted above based on my local track conditions I just don't see what yall are seeing at your local tracks that often especially in June,July,August,and September if the temps are still in the 90degree range threw out the day.
