what a good torque converter to buy
ok. all i have in fullbolt ons on my 2001 ss. right now im running 12.68@109 mph. the next thing i want to get is a torque converter but i heard that there are some torque converters that increase your topend and some decrease your topend. what would be a good torque converter for my car. also whats the difference between 3 disc torque converter, to a single disk lock-up torque converter, to a sigle disc torque converter. one more thing. what is STR. THANKS

The more the STR (2.0 vs 2.5) the harder the converter will hit the tires. If you opt for a multi disc vs a single it really varies on rather the car sees the track often enough. multi discs will run hotter, so a larger cooler is needed. If the car is mainly street driven you're best option is the single.
Running a cooler is needed with the larger stalls to prevent burning up, or killing the tranny sooner over its typical lifespan. Break in period of about 500 miles is highly recommended.. (cruise control doesn't count) the car needs to be driven at all speeds, but not hard launches.
TCI is trash, Vigilante or Yank is another choice. Circle D is nice. They can custom build you a converter, stall speed, multi/single disc option, a warranty, and the option to have it re-flashed fa single time for free.
Remember often like cams.. Don't go small and wish you had gone larger. a nice 3000+ stall is nice for a street driven car. I'd stay away from 4000... plus the gas mpg will fluctuate per given stall speed just FYI

I LIKE YANK
I suggest a SS 35-3600 with an STR about 2.3 -2.5, the latter if running good tires ( drag radials)
I ran a yank st 3500 2.3 for about 6 years , now running ss4000 2.5, have a spare yank 4400 2.6
I can not answer all your questions , you should pick up about 1/2 second with a good tc and tires
for your answers go yanks web site and check FAQ OR call and talk to dave or mike they will be happy to answer questions
good luck Johnny

The difference in a single vs multi is holding capacity. For a NA setup, single is fine. You want to step up to a multi for big power adders. So our Pro Series Stage I will be perfect for your setup. You can fill out our "Ask Chris form on our site or give me a call and we can go over your stall choices.

personally i think you will kick yourself if you go 3500. just like cams always go bigger. i ran 4500 lock-up (australian brand dominator) converter on a 3500lb holden ls1 with bolt-ons 4.11's ran 11.95 @110 mph, 1.60 60ft.
i'm investigating a circle-d for my L76 build, they're getting a good rep in aus.

Ive been extremely happy with my CircleD converter. I have a heavy (3900lb) 620rwhp car that lifts the tires off the foot brake with a nice 1.54 60'... and is dead nuts consistant every run.

I've heard lots of good things about Yank and if you look in the Drag racing results section these converts are cutting some nasty 60' times.

What is your d/a? That is pretty fast for a full bolt-on a4. Im only runnin 12.9@107. I culd have a better launch with better tires though and I culd run a cuple tenths quicker if I was alot closer to sea level. Ohh and I say go for a Circle D. From what everyone says they are as good if not better than Yank and in my personal opinion have better customer service than Yank.
