Please Help Me!!!

25thmustang · 07-10-2002, 11:39 PM

Okay, I just got back from the track, and I think I was ripped off on my torque converter, and my motor doesn't seem strong.

My mods to date are, 2400 (supposedly) converter, 3.73s, Cobra Intake, 65mm Tbody, Mac Cold Air Intake, 1.7 Roller Rockers, Mac Headers, Mac H-pipe, Flowmaster cat-back, BFGoodrich 175/40/17 Drag Radials, and 15x3.5 Drag lites and 165 tires. I removed the corner marker (poor mans ram air) and took out my back seat (left in bottom) pass seat, spare tire and jack. I ran a little less than 1/4 tank. I have a shift kit at home to install soon!

The best I could get was a 14.25 at 96. What is wrong??? My 60' is a 2.11 with a slight chirp, and I don't heat up the tires, or even clean them off. The car leaves like a dog, and I cannot bring the RPMs up over 1400 without the tires spinning. There seems to be no flash in the Converter.

Another problem I am havng is my trap speeds. Tonight it ranged from 95-96, shouldn't I be trapping near 100. My dads LX with cat-back, pulleys, and gears traps 97!!!!

I am getting annoyed here because this is my first car, and it is not performing how I would like. I have spent alot of money, and I would like some mid to high 13s out of this combo! is that too much to ask, and should I be happy at a best of 14.1.

Try heating your tires and launching at a higher stall speed, what RPM are you launching at now? Your combo should be at least getting you into the 13's

steven

PS Look at it this way, its better than trying to launch my stang which you can't launch (3/4's Throttle from idle=spin tires through 2 gears with a Posi rearend

)

MattwantsSpeed · 07-11-2002, 12:12 AM

dude, Did you run at Lebanon tonight?? I think, with those mods, you are ballpark for what you have. Maybe high 13's but you're times don't seem to be ridiculously low IMO.

OUTPLAYN · 07-11-2002, 12:14 AM

1st question...Why arent you heating up the tires?

25thmustang · 07-11-2002, 02:49 PM

I launch at idle because using the brakes the car WILL NOT hold itself over 1400 rpm. Plus I have a converter which should flash. The tires will spin no matter how hard I push the brake.

I don't heat the tires because off the line they don't spin. They have a tiny chirp and no spin at all. The 60 foots are 2.1-2.2 now and I cannot get any better. The traps last night were ranging from 95.62 to 96.49. I think the car should trap at least 98 or 99. My dad runs 13.8s at Lebanon Valley and traps higher and all he has is gears, tires, pulleys, and a cat back.

The car does not pull hard in the top end, and seems to dog out of the hole. It does not lay over or feel like it loses power, it just does not trap high. I am starting to get mad because I have spent thousands of dollars and low 14s SUCKS!

HiFlow5 0 · 07-11-2002, 04:42 PM

When I had my stock converter I could foot brake it up to 1500-1700 rpms without my tires spinning. What brand converter are you running? I have a TCI converter and it is suppose to have a flash stall speed of around 3500rpms, but its more like 3000rpms. I can foot brake that to somewhere around 2000 to 2500 rpms no problem, but flashing the converter gets it right up to 3 grand alot better. Also are you running a trans cooler? A must when you have a stall converter!!

Your 60' times could better! I was running 2.1/2.2 with stock 2.73's and stock converter. So get them down and I think you ET's would drop too.

Another thing, are you manualy shifting your AOD or are you letting it shift itself? Cause I noticed a .5 sec drop in ET's when I manualy shifted the tranny at a higher rpm. Oh and do you have a shift kit in that AOD???

25thmustang · 07-11-2002, 08:39 PM

I do not have a tranny cooler, but I was planning on getting one. The Converter is a TC performance converter. When I had stock 2.73s and a stock converter I could only get 2.3 and worse 60 foots. I manually shift it, doing the old 1, D, 1, D combo. Although my car holds first till about 5300 so I don't put it in 1 first. I don't have a shift kit in the car but I have one sitting in my room waiting to be installed. I know that with a 2000-2500 launch my car would pull much harder, but I can't hold it that high. And it does not flash at all.

I would like to get this sorted out soon, because on the 20th I have a Mustang race and would like to get in the 13s for it.

Do you have any suggestions on why it traps so low?

jetuomi · 07-11-2002, 10:38 PM

well, the intake might be moving your peak hp up a bit, and maybe your AOD is shifting before peak???

how's your timing?? it can really lower MPH if not set high enough.. (or set too high and you ping)

HotRoddin · 07-12-2002, 12:22 AM

What are your cam specs ?

25thmustang · 07-12-2002, 08:10 PM

The cam is stock, and the timing has not been adjusted yet. It doesn't ping, so it may be really retarded. I am definately calling the Converter company and complaining! My car shifts at 5300-5400 in the gears, so don't think it is too far off!

25thmustang · 07-13-2002, 12:39 PM

What about the Throttle Position Sensor, if that is off wouuld it hurt the car noticably?

HotRoddin · 07-13-2002, 06:35 PM

You're probably right on the money.. you aren't gonna hear it ping because the puter could be retarding the hell out of it to keep it from pinging. Try a run with some racing gas before you change anything ... If the problem is the puter pulling the timing back, then a run with the good gas should solve that and your time and your MPH should show noticable improvement.
Oh and after you solve that mystery, lose the stock cam ! You have all that good stuff and your chokin it off !!

LX5liter · 07-13-2002, 08:00 PM

Start by fixing your rear brakes. If your brakes can't stop it from spinning you will never get a true convertor read. After that check your tune. It sounds like your not getting a whole lot of torque (which affects converter stall speed drastically) out of the hole. The timing and ignition are a great place to start.

25thmustang · 07-14-2002, 02:28 PM

All the parts on the car have 30,000 miles or less except the cam. I don't think it needs a tune, beause the wires are FMS 9mm, with about 10,000 on them, the rotor has the same and same with the plugs. I don't think it is the brakes failing to hold the car, because you can feel the converter lock up, and even if it was the brakes, wouldn't the converter flash to its stall speed, and it would at least spin the tires!

I am running the stock cam because I am in a Factory stock class and I had to remove my B-cam, which I took out before all my other parts went in. I also adjusted the TPS, but I don't think it was affecting me too much.

I know the car was down on torque when I had my 24lb injectors and Mass air in it, and when i changed those it picked up alot of torque down low!

25thmustang · 07-15-2002, 09:49 PM

Does anyone else have any ideas to help the top end more. I think I can figure out the converter but still don't know why it wont pull up top.
