I already have a BamaTune 91 Torque tune with CAI and synthetic oil in the engine of my '07 auto. I took the spare tire and jack out to save a few pounds and replaced them with an electric pump and tire slime. Race weight with me is about 3750-3775lbs. I will get an accurate weight at the track. Would an off road H pipe and UDP's get me close to 12.9's-12.8's with the stock tires and good track conditions. Or would a stall convertor and drag tires and/or an aluminum driveshaft be a better bang for the buck. I want to keep it stock as possible. I am not interested in nitrous, long tubes, delete plates..ect. I might go with 3.73's at a later date. I hope to baseline my car next weekend at Beech Bend if the weather cooperates. My ultimate goal is 12.60's with tires. THANKS

Unless you have really good air where ever you live 12.9's are not likely even with the mods mentioned. 12.5 your hoping for to much. I have an auto with all the factory options plus the mods you see below and the best I've run is a 13.7. Go to the track with what you have now and see what you run. If you happen to run a 13.5 or lower which I doubt you will then I'd say high 12's will be possible with your car. I'm not trying to be negative just letting you know what to expect.

For comparisons sake-(Shawn I hope you don't think I'm ******* on you cause I'm not I'm just trying to explain that mods don't always deliver what you think they will.)
I have a friend who's got a 06GT auto w/CAI/tune,tb space, CMCV delte's, x pipe, slp mufflers, and aluminum driveshaft and I beat him 2 out of 3 races at the track. (disclaimer now when I say I beat him it was by less 10th's of a second. It wasn't like I owned him or anything. We didn't even know if we'd won or not untill we got are slips.) The only thing I can see slowing him down are his rims and tires which are 18x10 deep dish in the back with fatter rubber. Even then I'd say the weight of my side air bags and shaker 1000 about even us out.

Keep in mind I only have cai/tune, O/R H, flowmasters. We both have automatics so drivers are out of the equation.

Here's another stat about our cars. We both had them dynoed the same day at the same place and here are the results.
His car 296rwhp don't remember the torque (Shawn/Osiris if your reading this send me a PM so I can add your torque)
My car 282rwhp 324tq

So did his mods add more HP? Yes but did it make a difference at the track no.

Sorry for the long post.

EDIT***
One more thing I've removed my front swaybar,spare tire,jack,trunk mat/carpet and done comparison runs at the track and didn't notice any difference. Unless your going to go all out with weightloss it's pointless since you need to lose at least a 100lbs to gain a 10th of a sec.

What's wrong with deletes?

Hey 2007TorchRed,

Check my sig below for times. A tune and CAI should get you in the 13.50's Now mind you I ran at Englishtown NJ which if I remember correctly is 300 or so feet above sea level.

I have since added UDP's and the GTA mufflers. I am shooting for 13.30's when the track opens.

I think it's going to take a set of gears and sticky tires to get into the 12's

Good luck and keep us posted on your progress.

I've seen two cars, both manuals, run well into the 12's with intake, tune, offroad pipe, pullies, and drag radials. Stock gears, full weight, etc. Autos seem to run slower but I think that's typically caused by how they're launched and the shift points being used.

I think that it's funny when people talk about "not racing dyno's" or that "dyno numbers don't matter, it's all about how fast it runs on the track." I'm not saying that dyno numbers will tell you how fast the car is, I'm only saying that you CAN NOT tell how fast a car really is on a dyno OR a track unless all things are equal, SPECIFICALLY the driver.

The driver alone makes the biggest difference; how the car is launched and how/when the driver shifts is crucial to how quickly it runs. Case in point: my car with all the mods I have has only ran as quick as 13.3 with me driving it. On the same track, on the same day, cars with less mods and less power were running high 12's. That's why I say in my signature "Driver Limited" LOL, because I'm not afraid to admit that if someone else drove my car or I had more practice at the track (only been there 2x, total of about 12 runs) I think my car would certainly run better than 13.3.

Leo, even in your post IMO you can't say "We both have automatics so drivers are out of the equation." To truly prove that, next time you drive his car and let him drive yours. You make some very good points don't get me wrong, I'm not trying to argue- I'm just trying to express how important the driver is to the equation.

This is a pretty good read here regarding the subject:

Tbone-Awesome times. Not to take anything away from your car but being below sea level helps alot. It's proabably the differnce between my 13.7 and your 13.5. With that said the track I go to isn't a real track it's Qualcomm stadium parking lot prepped twice a month for racing.

Tom281-I don't see how me and my friend switching cars would matter since we launch at idle. The only other possible variable would be reaction time but even then RT has nothing to do with ET.

tom281

Go ahead and swap cars next time just to be sure.......

BTW, your post above says that your car makes 282/224- maybe it's that lack of torque that's letting you win the race LOL! Just pickin' on you with that one....... Anyway Leo like I said I'm not trying to argue with you specifically or anything like that, I'm just trying to emphasize how important the driver is to the equation. You make some great points man!

I should be the last person posting about this anyway, since I haven't broken into the 12s myself-

2007TorchRed

I think Beech Bend is about 547 ft. above sea level. Hopefully the track temps next weekend will be in the 50's. One of my friends got a G-Tech from his wife for Xmas and if I get some spare time tommorrow before the rain comes in I might do some runs with it and practice my launch. With my factory tires I will have to learn to take off easy and floor it when I get moving instead of putting it to the floor when the light drops. Putting it to the floor is more fun though but not good for low ETs. I will probably get an H pipe this summer and maybe some UDP's by winter. After that I will get some drag radials. Anyone in the Bowling Green area going to be at the track next Sat?

Actually 2005 Auto, with UDP, Corsa exhaust, Full Steeda CAI, 4.10, Bama 93 Tune : 1.90/8.27/12.90@109.693 , Street tire with 18*9 Heavy wheel.

And a friend of mine with a 2006 Auto, with UDP, Full Steeda CAI, a 93 Tune, Offroad H Pipe Prochamber, American Thunder Exhaust, Stock tire. 1.97/8.32/12.97@109.443.

This year with a new upper and lower control arm, Some 15*10 light drag wheel and some slick i'm looking for 12.70.

I think i saw one 12.8x 2005 Auto in the time slip thread, on street tire.

EDIT : 3725 LBS

ren274u

my car first broke 12's with a 12.87@106, JLT2, bamatune, steeda udp, 3.73 and offroad x on stock pirelllis

enitalp what track was that at? those trap speeds are way high for just those mods.

bigaloz

My car ran 13.6 bone stock. With an Alternative Auto tune, C&L Intake and 4.10 gears I went 13.02 @ 105. Spare tire and jack still in trunk.

enitalp

It was you in 12.8x .

I'm always between 107/109 mph. At Nappierville Dragway near Montreal in Canada.

My time was made in october. 3°C, pretty cold day.

LEO_06GT

Dam you Canadians and your good race weather.

enitalp

Yeah ! and our 5 months without our mustang. My mustang sleep from 1st november until 1 april . And i'm not canadian.

TBone69

It looks like I am only some gears away from hitting the 12's.

I had planned on getting a set of 4.10's in the near future but it seems it getting time for some new brakes and that cut into my gear funds.

New performance rotors, pads and stainless brake likes are on order, gears will come later in the year.

enitalp

Gear doesn't change the time in my knowledge.

ren274u

wasnt me i live in south florida and did this at moroso on a hot day.

LEO_06GT

+1 from what I heard/read if you have an auto a torque converter will help you et more than gears.

enitalp

But the fun factor of the 4.10 + bama torque tune = .

Actually stock auto gear is annoying.

With the 4.10 i took 0.2s advance from a manual 05 friend at the 1/8. when reaching the 1/4 i still have 0.1s, so i lost 0.1s from the 1/8 to the 1/4 . He got the stock gear. That also mean that the 4th of auto are slow .
