Hey guys, blackhawk0251 asked for some videos of stalled cars driving around so everyone could see how loose different converters were during normal driving. I found a video of my car with the Yank PT4000 torque converter, 3.23 gears, Kooks LTs & ORY, and Magnaflow catback and posted it to Youtube. Most of it is just normal driving in different conditions, but I also made a couple of quick pulls to show the shift extension. My car ran an 11.968 with this setup at full weight.

On your 11.9 run, what other mods? what 60ft? and what mph?

1.65 was the best so far, but that was on a 45 degree night on 275/40R17 Nitto road racing tires. I had to leave the line pretty easy to get it to stick that well.

Very nice, 1.65 is nothing to laugh at on Nittos. Man they can be a pain to hook with a decent converter. Best 60 for me on Nittos has been a 1.69 once, and a couple 1.70s.

Jesus dude, was that on stock suspension?

What is the difference between the PT4000 and the SS4000?
The STR?

Curious which would be a better stall for a decent shot.

So do people use 4000 stalls to save gas on the street? Isn't that less fun?

^^ to save gas? i dont think any converter will save you gas besides like a 1K stall, and it all depends on your right foot

Yep, on stock suspension except for UMI poly/rod LCAs. The PT4000 has a lower STR unless you custom order something different, and is designed for N/A. The SS4000 has a higher STR and is reportedly safe to use with a small-med shot. If you are planning to run a Yank with spray, I would look at the SS or PYE line of converters.

Opposite. It uses more gas but it's a LOT more fun.
