the car was dynoed last year by cartek making 366 hp at wheels.car is hard to start when hot if that helps.tried launching anywhere from idle to 3500 on the brake not much of a difference in et or 60 ft

109 mph this time of year with that rwhp seems about right for a full weight car.
Your 60' is pretty bad.
Have any vids of the car at the track?

yea i live in middeltown.yea 60 ft is bad but it wont get better no matter what i try.i was at track yesterday and lid and exhaust stall car were beating me.u think u could look at it for me.u have any ideas

start with the normal stuf. hows the tune up parts? plugs wires filters? the hot starts issue could be tune related or some thing else. and you should be traping more then 109 even in the heat.
whats your exhaust set up?

Are you heating up your slicks enough? I was having a similar problem with my drag radials and it turned out I wasn't getting enough of a burnout. I went from a 1.88 to a 1.58 60ft after I started heating the tires up real good. If you can improve your 60ft down to a 1.6 or better, that alone will put you in the 12.2 or quicker range.

i had it tuned with borla catback no cats and now running not cat true duals dynomax bullets dumped no h or x pipe. no matter wat i do for a burn out long or short doesnt make difference.idk even if burnout was good shouldn't i be trapping higher

Ahhhhhhh, the clouds clear.
That could certainly affect it. Why don't you call Cartek and have them check your tune or at least see what they say about the exhaust change.
I know Julio wants to check the tune after "EVERY" change-even wants to dyno the car with the tires you race on.

Is the car hooking good?
What are you shifting at?
Whats the track Alt.?
Have you checked fuel pressure?

You should be 60fting WAY better with those 4.11s in an A4 & that stall if its hooking. Start checking all the little thinks 1st., make sure the MAS coils are clean, run a FP test, check plugs/wires, batt/alt. voltage, the hard starting when warm is a strong indicator that something is wrong somewhere.

it spins a little but i still think i should be traping higher im going to hook up a wide band and see what up.i think my friends has some vids but i feel it doesnt have power out of the hole at the track but on the street from a roll it moves i cant figure it out

KillA98Z

iTrader: (1)

could it be exhaust becuase last year through borla catback i ran 12.98 on street tires.this year i have 4.10s slicks but i also put true duals no cross over with bullets could this be the reason

It's the 60" that's killing your ET!
First question, are you saying there's no merge pipe at all? Cause you wrote no h or x pipe.
I'd try staging and just let it idle, then when the thrid light comes up stab the pedal, no reving or anything. See how that works, that seemed to be the best way for me.
Do you have any suspension parts?

KillA98Z

iTrader: (1)

one 3 in pipe off each header no y no h no x stright back to bullets dumped.i tryed launching every way it doesnt make difference doest seem to have the power out of the hole

bad6as

iTrader: (17)

mabye try a cross over

You need a merge, buy a 3" in/out X pipe off Summit or somewhere, than get that fabbed up. Or you can also have an H pipe setup fabbed up.

so u guy think thats the problem

Your 60ft. does need addressing, i would kill for that 60ft. though with my M6, you need to always check the Barometeric Pressure & calculate the DA before you race that day/night, your MPH should be better too, but depending on how bad the DA was, you could be looseing alot, your exhaust could be some of the problem like was mentioned (i don't know), but a 109 trap speed is good for 12.2-12.3 range if your in the 1.7s on the 60fts. I myself can & will loose 2 mph from week to week in these summer months & around .2, I would think for sure you have an issue if the car fells sour leaving with that stall/gears your running, you should be in the 1.7s easy, the lower MPH also says its not up too full strength, i would think you should be going 112-113.

you have a 98 have you upgraded to the newer knock sensors and harness...my car would pull somthing like 4* of timing at WOT....may be somthing you want to look into...

its a 98 with a 01 engine.but at the track with my dad watch it leaves kinda dead but down the track it builds up and srceams on topend. i think the exhaust is killing the torque out of the whole because that was only thing changed sinced it was tuned
