101 seems slow for a trap speed. i dont think it's the shifting. get her tuned up, seafoamed, clean up the maf, make sure everything is running right and you should be mid 13's.

changing the plugs sure is easy with the exhaust manifolds out of the car lol so yea if you have the resources to get headers and a full exhaust and a tune, do it. Also, touching that rear would be the last thing on my mind. listen from me, i changed my gears now i regret it. i wish i would have kept the 2.73's and just gotten a stall. stall converters dissipate that gap between the highway geared cars and the street geared cars really quickly, and you still get great hwy mpg. with the headers, intake, tune, tuneup, and a stall, you should be running mid 12's.

 

You can get a 10 bolt with 3.42's for under $200. If you look, you can probably find one for free.

I would get a Dyno tune and see what's up with the car. A4 should run low 13's, M6 high 12's stock.

 

maybe with john force driving...

not very many people at all can hit 12's in a perfect running stock m6 fbody without at least drag radials.

 

There's no way he would go anywhere near 4th gear with 2.73s. Second gear should be good up to 95 mph and 3rd should go until 167 mph.

DA stands for density altitude and is given in feet. It's pretty much a calculation based on the temperature and humidity. You want it to be as low as possible. A DA of 0 would be equal to racing at sea level under some standardized conditions.

 

Don't sweat it too much. My best stock time was 13.6@ 102 so considering the gears ur in the ballpark. Plugs/ wires + clean MAF might really help you out. Mine WAS low mile car with good compression so it was healthy.

 

ok heres the time slip 2.25 60ft 9.30 1/8 mile@78mph 14.1 1/4 mile@102.5 what does that tell you

 

It needs a tune up. Kinda falling on its face on the big end.But thats dependant on your DA.

 

alright man..when my car was stock..i had 2.73's and the best 60 ft i could get was a 2.0, this was on drag radials not spinning one bit.. if you could get your 60 foot down to a 2.0 you could easily knock off .3-.4 off your 1/4 mile time..that would get you faster than a 13.9..also when you do your tune-up dont forget to change the fuel filter..also next time out, take out your spare tire and jack..and go with like a 1/4 tank of gas..you should have no problems getting into the mid 13's with a stock car

 

i dont know about that john force BS Comment..i ran a 12.5 @ 110 mph with a 1.85 60ft and all i had was exhaust and dr's...and mine is a M6 and that was on my bone stock 10 bolt and stock everything else..

 

Nobody can, they dont run that fast stock. John force cant either.

 

^^^^^My 13.6,s were with 2.0 60's so your right on^^^^^ .1 on your 60 =.2 on et as a general rule

 

i hear what you guys are saying but to lower my 60 ft means to hook up and go but i dont think i spun at all...some guys in town here are going to us41 on friday maybe ill try again its much cooler out now i cant do the tune but i can seafoam it. damn i just filled up yesterday too

 

Tony (Nine Ball) ran like a 12.89 or 12.86 in a bone stock 1999 Camaro SS I thought. Down to stock tires.

I'm pretty sure I heard it.

 

Nobody can, they dont run that fast stock. John force cant either... LMAO WHAT A LOAD OF UTTER BULLSHIT!!! sorry man but that is total BS..
anyways...try dropping some tire pressure on the track..i usually run about 15-17 lbs..that may help you hook better..

 

It does not appear you have any issues on the back half as evidenced by a 24.5mph gain from the 1/8 on out the back door. The 60' however stands to need help. Even dropping to a 2.05 would get you solidly into the high 13's.

 

thanks again guys for the help. i look forward to getting back to the track. for the local guys to me ive heard that us41 will run slower than rt66 times is this true

 

You run 15-17psi on street tires? or on dr's?

 

Don't get any mods yet. Just get a tune up and fix the issues the car might have before throwing money into mods.

Run it once you do the tune-up (filters, oil, spark pugs, etc...) I guarantee you'll get at least mid 13's with a 60ft of around 2.00 or so.

After you know your car is running like it should, start modifying it.

 

I went to Osceola two Friday's ago and witnessed this firsthand. The 2.73's in an A4 car blow with a tight stock torque converter. I swear it took 3.5 seconds to reach 3,000 RPM after launching the car. It totally bogs down and takes forever to get breathing. I made one N/A pass at 13.8- but my car had serious MPH on the big end, and that is what saved me from a 15.0! I made 4 more passes with my wet kit and with 100hp tune-up the car went 13.05. Lucky for me I have headers, BMR LCA's, a cam, and a 3000 RPM stall Fuddle torque converter waiting on me to install them...

Good luck with the 60'. I think a stall converter would be a wise choice for you. You can pick up a used one for around $300 in the for sale section.

And good luck at US41. Last time I was there, they were having problems...

 

dont be so cocky bro. your comment about exhaust and dr's running 12.5 yeah i can see that in a car that's running great, but it's not STOCK. exhaust can add 1-2mph and maybe .1, but dr's can take a shitload off the ET since you were able to hook. 2.0 60' on that run and you would be looking at barely touching 12's, if you didnt spin at the top of 1st or in 2nd.

thanks, that only reinforces my comment that it requires a great driver on a good day in a stock m6 car to hit 12's.
