Honestly... I just want to say you have an awesome sig...

 

Where are you finding automatic cars that are running mid 9s? The plugs were probably fouled if they were that slow. That's were your gain came from.

Believe whatever you want.

 

I'm kidding. All of the auto cars I've seen that slow were just out of tune or running walmart tires.

I picked up 6 tenths with an exhaust, and intake. And decent street tires.

Here's the other ones:

 

no offense, but you 9.4-9.5 guys suck at driving hahaha buddy of mine had an auto 99 t/a and he was running 8.6s and 8.7s stock. I too ran 9.4 when I first started racing but that's because I'd never raced a m6 before. Now I'm doing much better! With an auto it is much more than just stomping the gas. You've got to develop a launching technique. Just practice and yes your car is already capable of 12s as is. Just learn what works for other people and experiment.

 

My car ran an 8.9 stock with 100k miles. I ran a 9.4 with a dead clutch slave and Sumitumos.

 

My point was that you don't have an A4. An M6 can pick up a second or more on back to back runs just due to driver.

The other guy actually does have an auto. So I'm not sure about that one.

 

Headers on a stock stall A4 most defanitly help out. I went from 13.3s to 13.0s. There is a buddy of mine that has a 98 SS that runs on ET street radials so there is no error on the driver part there that went from 13.4s to 13.0s with a set of kooks 1 7/8 header. He also didn't loose any on the 60 foot supprisingly.

 

thanks for the advice im getin my car tuned with in the next 2 weeks then i got to wait for the track to open up and see what she will do with the few things i have done and in the mean time im going to practice my launch

 

There are always some they work better, same with gears. Most will be wasting time and money for very little gain.

I still really have a hard time believing .4 gain from 1 7/8 kooks. Same DA, same track, same state of tune. What was the MPH difference? If that's the case, then I really need to get some headers. I'd be running low 11s then.

 

for some reason i couldn't quote the one u quoted me on so i'll just use this one. I saw no differance in my 60's with a stock car and then header car. before i did the headers i had a 1.99 60' and then after the headers 1.99 and i hit a 1.97 once to. This is one the same street tires that i have been using since the day i bought the car. Yea i know the sixties could be better but i don't care.
now for the weather i ran the car at night when it was stock and it was 70 degrees and with the headers i would have to check i believe it was mid sixities during the day.
This is all at the same track which is raceway park NJ.

 

when "omgwtfbody" was running those 9s he was spinning horribly and had some bog off the line as well..




as far as the headers debate goes.. i want to see some graphs where people lost TQ... anywhere across the board.. same dyno..

i would also like to see some time slips or something where people only changed headers and ran same track etc.. in very similar HEAT or COLD... that there 60 foot was slower..


headers make you car faster.. no if ands or butts... i can see where your coming from but they pick up so much mid and top end range (where your car is the majority of the track 1/8 or 1/4) that it is GOING to give you a better e/t and a better mph...

 

Most of the time the 60s will suffer, but yours stayed the same. So I can see the increase. Did you happened to add a torque arm or anything during the header swap?

Your ET/MPH is good for the mods and the 60.

 

He has a 6 speed. Who give s **** what he ran. It's has nothing to do with anything in this thread.

Well, after a little searching. I can't find any back to back header dyno graphs. Please feel free to post some if you can find them. People just want to give peak numbers, no graphs. Also most dyno graphs don't start til 3000. Which should be all gains from there up. Where stock stalled autos are lucky to see 3000 rpm at the 60'.


Still most I've seen only gain 20 max. Going off rule of thumb that doesn't equal .4 and 4 mph as has been claimed in this thread. In my car, where the tach doesn't drop below 5300 rpm at WOT, I might could see that kind of gain. I hope you're right. I'd love to see .4 and 4 mph with a set of headers.

 

there are some out there for both sides of our argument.. i have seen them.. i honestly dont care enough to spend the time looking for either of them.. (keep in mind i am backing my side and your side by saying that)
with that said, i have seen many many more with headers helping..

hp doesnt mean anything.. same with TQ, its about the performance.. a stall doesnt add any HP and your going to be running half a second fasters.. sometimes more.. so just because either of us show a graph with headers hurting or helping either one, it doesnt mean anything..

i never said you would see .4 or 4mph.. i doubt you would with JUST headers and a ORY.. now with a cutout in the mix... i could see that and maybe more.. depending on the car..

you have to think.. headers arent going to actually hurt the 60 foot.. if ANYTHING it is going to be a 1/10th or less.. after that, your above 3k.. you have a lot of ground to make up a big difference.. and that is where the e/t and mph is picked up.. 60 foot isnt EVERYTHING... it is most of it.. but not everything..

calm down there.. haha.. i was just backing him up.. i didnt say his car had anything to do with the thread, he came in here with a m6.. not me..




all in all, i agree with the headers helping.... and i can def. see where you are coming from and have a very strong argument.... but think you are looking over the main point..

 

And that is? That my car ran faster than every car that posted in this thread expect 1 with only a lid, catback and ram air in 70 degree weather. And now with a stall runs faster than a lot of cammed cars, still without headers.

My point was that if you're gonna spend a ton on headers, just buy a stall instead. If you're gonna buy cheap headers and install them yourself, have at it. You can go fast without them though.

 

get full bolt ons and suspension ..should be in the 11s

 

headers help out alot when u got a cam..bolt ons ...maybe .1 off and about 2 mph gain

 

that headers do help a lot more than they hurt.. granted they may hurt you sixty a TINY bit, or it may stay the same, some possibly could be better but doubtfull.. but you are above 3k rpms pretty quickly, and above that, headers will help a lot.. so you are overall going to be quicker and faster..

i agree that a stall would help a lot more than headers..



BTW
if your car still has the mods you listed, or even close to it.. your car is no where near as fast as mine.. even without me knowing your times, i would bet on it, and i have headers..
although, that does not make either one of us right or wrong necessarily..

 

I picked up 4 MPH with headers and an LS6 intake in the 1/8th.

And that's a consistant number. Before the mods I was running anywhere from a 9.0-8.7 in the 1/8th, but it was always at 81.8-82 MPH.

After the headers/LS6 intake It ran 85.8-86 in the 1/8th.


And I don't know who the guy is that knows about my track times. lol.

 

Thats more than just headers. The headers alone would not have netted that much of a gain.
