Default Low 12's - hoping for 11's soon

My 2002 TA (base)
Best run so far is 12.27 @ 113.55
This was after installing 4.10 gears, before the gears my best was a 12.60 @ 110.43. Dynoed at 340 HP before the gears, and 330 HP after
The car is mostly stock with a lot of weight removed, only door panels, dash & driver's seat remain inside the car.

Mod List:
  • UMI: SFC, Panhard Bar, LCAs, Torque Arm, Torque Arm Relocation & Driveshaft Loop
  • Aluminum Driveshaft
  • 4.10 Gears (unknown brand and in stock rear)
  • TA Performance Diff Girdle
  • Removed: Sway Bars, Cat-Back (including Cats), AIR, HVAC, Power Steering Cooler, Windshield Wipers & Motors, Interior (except Dash & Door Panels)
  • Corbeau FX1 Race Seat
  • Racestar Dark Star (15x3.75) - Front Wheels
  • Black C5 ZO6 (17x9.5) - Rear Wheels w/Nitto NT05 tires (275/40/17)
  • SLP Lid & FlowPac Intake
I just had the transmission rebuilt & strengthened, and added a 4k Stall, but I have not been to the track yet. Trying to hit TNT this weekend.



Video of the run (wish you could see the time on the boards) -

With 113.5 trap, you just need to work on your 60' to get 11's. I went 11.66 @ 113 with bolt ons, ss4000, and 3300rw. Looking at your mods, the new 4k converter will help, but I'd suggest a better tire and adjustable rear drag shocks.

That's pretty good for a stock converter. How much does the car weigh?

Not sure how to get it lower, the tires hook. I am running stock shocks though
We will see how the new TC helps soon

You'll spin them with the new converter . Adjustable shocks with allow you to get more weight onto the tires. 1.8 60' with stock converter is pretty awesome, but leaving at such low rpms with little torque multiplication is why you aren't currently spinning. Now leaving around 4k where the motor makes good power along with a better torque multiplication will make a world of difference.

Edit: better shift extension will also help a lot.

Which converter did you get?

Yeah, that is why I need to get out to TNT so I can start getting used to the new setup before racing starts back up.
So the following was installed along with the rebuild (trying to read his hand writing)
  • 4179 Drum
  • Transgo HD2
  • Transgo High Rev Pump
  • Transgo High Rev Clutch Spring
  • Sonnax 2-3 Shift Valve
  • Borg Warner HD Sprags
  • Wide Kevlar Band
  • New High Reverse Drum
  • Super Hold Servo
  • Beast Sunshell
  • 5 Pinion Planetary Gears
  • Wide Bushings
The info just says FTI Triple Disk 4k Stall, I asked which model, but have not gotten a response yet.
Thinking about getting a mail order tune (until I can get to a good shop doe a dyno tune), just need to figure out what all I need to get done.
Trying to add a roll cage this summer as well, so the weight will go up a bit, but this is in prep for future upgrades, so I figure better now than waiting until it is required.

Got to the track this weekend.
I could not get traction to save my life, ended up running 12.8's with a 2.0 60'

So now I'm working on getting stickier tires. Ordered the wheels, and will get the tires once they arrive.

probably a 26x10.5 slick, going to borrow a set from a friend before I buy, so i can make sure it is what I'm wanting/needing

no exhaust, dumps right after the manifolds, the manifolds are stock though. I am looking at the tunes, probably going to get a mail order for now, until I can get it dyno tuned. Just trying to decide who to go with.

Bolted up a set of slicks and hit TnT again this weekend. Pulled a best of 7.76 with a 1.68 60', hopping the front wheels about an inch. I need to remember the good camera & GoPro next time. The below video is from a cell phone.

https://photos.google.com/photo/AF1Q...a40uKbJ64zoLFO

I ran a 12.27 (1/4) with a 7.91 (1/8), so a 7.76 should get me a 12.0/11.9 (1/4)
I also re-weighed the car while there and it picked up only 26lbs from the rollbar (weighs 3116 lbs now). Not as much as I thought it was going to get.

Still haven't made it back to the 1/4 mile track yet, but did make a race this past weekend, and ran a new best of 7.68 @ 88.88mph w/ 1.65 60'

Is there any way you can keep the front down and still hook? Might help your 60' if you can transfer the up and down motion into forward motion. Love what you are doing with the few mods you have!

Excellent work! So few people work on optimizing their combo before throwing money at parts. We did the same thing with my wife's '02 a few years ago:

Not sure what that would take, TBH

Thanks I've been pretty happy (and surprised) with the car. It is performing much better than I had expected

Thanks. Yeah, I want to make sure everything is set before I really start adding power. The Trans & TC were the last items on the list, so next will be new tires (current slicks are borrowed) & power adders.
