Went to track tonight,,need your help

[willys1]

I went to the track tonight and couldnt get lower then 14.7 My best is 14.3. Then I added a kirban FpR,,410's and drag springs and a t-moss lower intake!! WTF!! My 14.3 was with 373's!!

My 60 was 2.1.I have a trans go shift kit and it shifts at 5400.

The only good thing that I did tonight was to cut my best light ever,,,.005 ,other then that Im pretty frustrated,I could really use some help.

The air has been terrible lately, my last trip at the track was when it was 80 degrees, and very humid. The best I could do was 15.0. I think I had a vacuum leak but still, a few tenths higher then I have been running.

ok, i'm not gonna try to start anything with the great gear debate, but it does make me wonder........is your shift point the same as it was with the 3.73's? does it feel like it's running harder off the line but falling flat towards the top? i suppose the manifold could have something to do with it too.......was your 1/8 mile any faster or did they measure that at your track?
i'm no expert, but i'd venture to say if your 60' is better and your 1/8 mile is the same or better, your manifold is working ok off the line, as well as the gears, but the gears may be over revving your engine into a flat spot for the rest of the 1/4. thad be my guess, assuming it wasn't just a really bad day climate wise.

 

[willys1]

It was 84 and a lttle humid,not real bad. Yes,,my shift points are the same with the 410's.My 60's are the same,dont pay much attention ti the 1/8 reading,but my MPH is slower!!

Try messing with your FP...

 

[willys1]

I did,believe it or not it went 14.7 at 38lbs. When I cranked it up a few pounds it went 14.8,and 14.9.

 

[willys1]

THIS BLOWS Im not putting one more penny into this thing,Im getting a dyno tune!!! After that,if Im not running in the 13's Im selling this freakin thing!!

 

[timewarped1972]

well you were at 14.3..........was that fairly consitent?? you were close, if you can get it back to 14.3 get some heads and you'll probably get there. i'm curious, since i have similar car what are all your mods??? hey if it only has 43,000 on it maybe it just isn't broken in yet....lol.don't give up on it...

I wouldnt want to have to get heads just to get into the 13's. Obviously he has another problem, too bad I cant help you though. Maybe the tranny is starting to go south or something?

psst tremac swap

 

[axeman]

have you ever checked any of the spark plugs to see what color they are? i think the last thing you want to do is add more fuel on a hot day, unless it's running lean to begin with. i've found it's best to add fuel when the temp is colder, and take some out when it's hot. did your mph change with the change of fuel pressure? you ET change could be coincidence.

i doubt the manifold is hurting you. Tmoss has a nice reputation for his lower intakes. a dyno tune will really help. hopefully i'll get one sometime in the near future.

it would be helpful if you listed the breakdown of the two timeslips (latest and previous best). list everything number wise, try to take note of difference in weather, different track, etc.

I hate to say it, this is what an auto will do. My car was like that. Would run 14.2, then in the same conditions next week, 14.5. I suggest a T5 swap, but as for right now, get it on a dyno and tune it!

 

[cjman15]

i second that... definately try to convert that thing to a T5... or if you got a big enough bank, drop a tremec in tha mother! then you'll be good to go tranny-wise

 

[cjman15]

by tha way, 25thmustang... where did you pick up those leather seats in your car??? i want those... mine are pretty beat now... don't think i'm tryin to make my car just like yours...lol i just love those, what year are they out of?

 

[25thmustang]

LOL, I dont care, thats why I have so many pics of it. I got them from Saleen as take offs, for $500 (for BOTH) and they are 2001s. Id say call them, but I got them on special.

Ok end of hijacked post!

no i know, your right he should"nt have to put heads on it(although it seems more common for aod owners to need them for 13's ) but if it was because of the gears that slowed him down he'll have to upgrade something to get more power on top. the only reason i questioned the gears was because of the mods he made that was one of them and sometimes that can slow a car down in the 1/4 especially if it runs into a flat spot.

 

[willys1]

Dont say,I think its the driver,,ok! Heres what I got, CAI,,65mm TB,,75mm maf,,T-Moss lower,,screamin Demon ign,,FMS shorties,,off rd h-pipe,,Bassani cat back,,PI stall conv,,trans-go shift kit,,aluminum DS,,410's,,Hoosier Quick Time Pro's..I think this should = 13's.
