At the track last night....

[Kevinmach1]

Well,
I just had a new TCI streetfighter transmission, TCI 3000 stall converter, and an aluminum driveshaft installed and made my first couple of passes...

Before the changes on a very cool 55* night I ran a best of 13.69 at 100 mph. on stock tires.
Last night it was about 70* and more humid.
I ran a best of 13.55 at 100 mph.

I really thought I would have got more than that, but my tank was 3/4 full...LOL

Now I need some slicks I guess so I can leave harder than at idle and hopefully get below a 2.2 0-60' time.

Any clues as to why I didn't gain much???

Thanks...Kevin

You already answered your own question.

1. Before: 55 degrees and cool. After: 70 and humid.
2. 3/4 of a tank
3. Can't take advantage of the converter stall due to stock tires.

You actually gained some from the swap since the air conditions were worse and yet you went quicker. Come on man......it's not that hard.

OK, sorry.

 

[US-1]

No need to be sorry. Just look at your numbers vs the air conditions. You said yourself that you needed better tires so that would explain the sixty foot time. Your slight gain in elapsed time would come from being able to flash the converter from an idle. I doubt you will need a full slick though. Should be able to hook it with a drag radial.

The rut that a lot of people fall into is not having faith in their conclusions without getting 35 replies on a message board telling them what they already know.

I'm thinking that it needs to breathe a little better. Maybe do the CMDP's and some headers with a high flow x-pipe.

+1 to SD... traction first, power second. In fact, if you don't already have 4.10s in there, those should be next after DRs.

As you mentioned above, your 3000 stall converter is useless with a street tire, go with a good DR first, then revisit the track.

I am assuming you are spinning out of the hole, since you can not leave harder then at idle?

Yeah, I can't even keep the tires from spinning while I'm staged if I power brake it... I'm sure I look like a real rookie spinning before the lights even go yellow...LOL

 

[grampa_stang]

You need to push harder on the brake then.

Or back off the gas a little. You're pushing thru the brakes.

 

[TexasKyle]

Oh..and the stock tires HAVE to go. You can forget about getting any kind of consistent traction with the stockers. Or traction period for that matter...

Tires definitely need to be the next thing you get...without a doubt.

 

[Bkid]

Drag radials could buy you a lot of time. If your slipping your not winning. MT drag radials would help. Lower control arms would help. I know you can get a lot off of that Et with just some suspension, and good DR`S. Upper control arm would help also. If you do have these disreguard.

with nittos, 4.10s and a the same converter back in 2006 in 05 GT auto i only picked up ~tenth or two and lost 2-3 mph.

i went from 1.99 60 fts on the stock tires to consistent 1.84s on the nittos with the converter. the car would not spin at all.

it usually ran 13.2-13.3 @ 102. with the stock converter i was running 13.33-13.4s @ 103-104

Now Kevin.... before you go buying any of that stuff call me. I have stuff.
