Car not running so hot ideas? Why would I only run 15's?

tarch · Oct 26, 2004

I just put on the BBK OR H pipe and i think i feel an exhaust leak... not sure tho

anyway
I am going to devote a day to cleaning up my car... anyone have a short/long list of things to replace while i am at it?

air filter
sparkplugs
oil
oil filter

what else could be causing my 15 sec runs?

i am going by blood ent. soon to try to figure out my ecu issue...

let's see... hmm anyone have any ideas? and no i am not a sucky driver... roofles... i am going to go to oregon one of those days to see if i have any improvement

let me get the time slips for a little more info...

rt: .500
60: 2.468
1/4: 15.319
mph: 92.7

60: 2.416
1/4: 17.640 <-- missed 3rd gear
mph: 71.83

rt: .345
60: 2.609

i had another slip of 15.013 but that one flew out the window as i was trying to snap a pic of my bro's car on the freeway... heh

hmm my stock fox was at 14.8 at 93 but that is a lighter car but it only had 2.73 maybe its shift points or maybe just not quite fast enough between gears or you could just have a slow car and the people running in the 14 have a fast one or they are power shifting and you arent (plz dont) i dont do that cuz i want to drive it home after a night of racing.

tarch · Oct 26, 2004

well i am pretty sure i am quick between the gears... i am thinking the launch is what messes with my times

Your trap speeds are extremely low. You should be running at least 99mph. I think you're power is really f'ugged up.

You need to head to a dyno and get it tuned ... pronto ...

Fuel filter?? does the car run rough? try cleaning out the maf wire with some brake parts cleaner, but dont toutch it. when I put on my cai w/ a k&n filter my car started running rough after awhile, I think what happened is all the extra oil thats on the filter gets blown through and some of it gets on the maf wire and all the dirt and impurities that dont get cought by the filter, stick to the maf... anways I sprayed mine off with brake clean, let it air dry and it was good as new, car ran alot better.

edit: 15 sec??? my 98 gt will keep up with that... and its an auto

Well.....if I remember right Kalin, you couldn't seem to muster up any real good numbers when your car was an auto, so I doubt it has anything to do with your shifts like you said before. I would definately see what your numbers are, they will give you a better idea it's power or traction, seems more so like power. Maybe check your exhaust and driveshaft. Hope you get it all checked out.

time only · Oct 27, 2004

Your mph seems to be a bit low,have them do a compression/leak down test to make sure all yours horses are still in the barn. Check the timing while you are at it.
What are the upgrade/gearing on your car ? That would help everyone . And what is the stories on the ECU ? Did you change it over from a different year model or you are running a "chips" ?

um...2.3, 2.4, 2.6 60's?

yes you are a sucky driver

Is your car lowered?

i have a cobra IRS... i hop... i hop a lot

about the comp... i still have my automatic computer in my car and none of the dealerships would copy my pats codes over to the new manual computer... i hate ford dealerships

These is my time back in April:

r/t: .611
60: 2.446
1/4: 14.915
mph: 94.37

i don't get it... i suck at driving... haha 60's are the same (almost)

Wouldn't go so far to say your a "sucky driver" but your 60ft times jump out as a big problem. Not throwing stones here - mine are pretty crappy as well. Try lauching from idle and then work your way up, feathering the clutch and launching at higher and higher RPM's - without spinning. With just a 2.3 sec 60ft, you'll be in the 14's no problem.

stock50LX · Oct 27, 2004

The 94-95 mph seems reasonable for a car of that weight, your more recent mph may reflect a problem. Your 60ft times must come down. I don't know what tires you are running, but if you are going to drag race, you need either drag radials or ET streets or slicks. With the latter two of those listed, your times would drop drastically. Drag radials can work great, but you will be dependent on track preparation which is usually not very good on test and tune nights. What size wheels are you running?

ccjcobra99 · Oct 27, 2004

kalin, is your IRS still stock? Some modifications to benefit handling will also greatly improve the cars ability to launch and reduce wheel hop.

Consider the following in no specific order:
shocks
springs
IRS diff bushings
IRS subframe bushings
03 cobra diff brace
IRS control arm bushings (delrin or nothing).

I definately think you should get the ECU looked at, as the auto to manual could be affecting it.

Definately DO NOT put drag tires on an IRS car unless you want to replace halfshafts.

yep IRS is stock and I am not planning on going with dr's or et's

my problem was the fact that i was going so slow through the trap... do you guys think it's normal?

i'll definately get a tune soon and i will postpone the blower until everything is sorted out

Juiced87Notch · Oct 27, 2004

your car used to be an auto ? wear did you get the parts for the conversion? did you buy a kit, or just piece together what you needed?

Turbo92PGT · Oct 27, 2004

Damn man! That sucks. YOur car looks really nice though hehe.

My 98 gt with a 2.3 60' runs a 14.410 at almost 98MPH. Somethins wrong with your car. 4.10's made my car faster on the street but track times did not improve one bit. Good luck getting that taken care of.

PM me so I can give you my number for when you're down at blood. I want an excuse to stop in there lol.

Ummm.....In the dealers defense, you cant just cut and paste the flash into the pcm. When you get a pcm from Ford, it is blank. You must transfer the flash from the old pcm to the new unit. When you do that, the part of the flash that controls the trans will be transferred along with the pats calibration. The tech's have no control over this, it is how Ford does it. Before you go hating on the dealers, understand that there is only so much they can do. The techs are not allowed to do anything outside of what Ford lets them do. Your best bet is the aftermarket.
