Yank PT 4000 driveablity and other questions.. Well i just got a ford 9" put in my car with a detroit locker and 3.73's.. I currently have a Vig3200.. and it doesn't seem like the car launches all that hard.. and i think the rear can definately withstand harder launches.. I pulled a 1.73 60 ft on cooper tires.. so i am trying to drop that quite a bit to the 1.5's... I am just wondering how driveable the Yank PT4000's are and if it would make much of a difference over the Vig3200? What is the shift extension on the PT 4000? I just don't want to buy it and have it be major overkill..
If anyone can help me decide if i want to make the move and swap converters, i'd appreciate it.. if its only worth 1 tenth.. talk me away from it haha.. i'm hoping for 2-3 tenths from the swap atleast.. Let me know what you think and how the driveability is and the shift extension! Thanks!

I am running the pt 4000 I love it. I drive the car everyday and it is fine on the street i lock up at 45 in 4th an 30 in 3rd. I have a stock 2.73 rear. but 9in 3.73 and the pt 4000 would be a great combo. without the stall i went 13.05 (2.0) to a 12.55 (1.80) with the stall and some tiny nitos but i know it is good for a 1.60 60' but i will find out this friday cus i just got my et streets in.i know the ss3800 is also a good and popular stall but with a 3.73 gear i would go with the 4000

awesome! i'm glad to hear its good for a daily driver! i heard it was pretty aggressive too.. I just wonder what kind of times i can expect to see drop compared to the Vig 3200.. anybody else switch from a 3200 stall of any brand and go to a PT 4000? what kind of et drops did you see? Thanks for the reply mr. rob.. anyone else have opinions?

I made the change to a TCI4000 from a Vig3200 and dropped .15 - .20 from my ¼ mile ET. My 60’ went from consistent 1.65 to consistent 1.55. The shift extension with the Vig was ~4700 and the extension on the TCI is ~5400.
As I daily driver I think the 4000 is too much and I would not have a 4000 if the car was my daily driver. It is way looser than the 3200.

Instead of the PT4000 would i be better off with the SS4000? i heard it is a little bit tighter of a TC.. but thats awesome if i'll see 1.5-2 tenths.. My best run with the Vig 3200 was a 1.73 60 ft.. so if i can get into the 1.6-1.5 range.. i'm sure its possible i could drop 2-3 tenths with my draglites on! Does anyone have an opinion between the SS4000 and the PT4000? on a daily driver.. i don't wanna be revving to 3500 everytime i take off to get it moving! haha thanks Jnorris

I don't think you'll rev to 3500rpms everytime with the 3.73's. I plan on getting a PT4000 to replace my 3400 Midwest converter. Mine revs to around 2000-2300 on normal acceleration.
I'd guess it would be around 2800-3000 on normal accel.

I think you will love it, I had a pt4000 and went to a pt4400 and I drive the car 50 miles a day to work and back and race on the weekend, just lower your lockups and you will be fine, and may want to get a tranny temp guage for stop and go traffic

I agree the SS4000 is the way to go if your car is a daily driver with 3.73 gears. The SS4000 is great T/C and is capable of putting down 1.5 60 ft. times.

i dont know,you pulled a 1.73 with street tires.with slicks you might be able to pull a 1.5 already? try it with some slicks first before you buy the new stall.

Yea i just feel like i can't hook any more than what i did.. because i was dead hooking on street tires.. but i should of flashed my stall up more.. because i would just leave it at idle and mat it.. and i think it was grabbing the tires before it stalled up.. With the Comp T/A's on i can hold the Rpms to around 2000-2500 and then when the light goes i can launch atleast that hard or higher.. depends on when i start to get wheel spin.. i wanna try my stall out 1 more time before i sell it.. maybe i'll change my mind

Yea but how do you launch? do you hold your brake.. and rev it to like 2-2500 rpms before wheel spin and let off the brake at green light and mat it? Or do you just let it idle around 8-900 and just mat it? because when i put on the BFG's the other day checking to see if they rub.. it seemed like when the tires got a little warm.. i could pre load it to a round 2000 or so without wheel spin.. then i let off the brake it i burned out a lot haha.. 
Let me know how you launch! maybe i was doing it wrong at the track?

I found that when you brake stall, it is very easy so spin when you try to launch. I figured out why. If you let off the brake too slow its like doing a burnout. You need to pull off the brake as quick as you can and be comletely off it before you floor it. To get the best results I brake stall up to 3000rpms and then quickly pull off the brake and wait a split second before I give it full throttle. Its all timing. I was able to pull a 1.71 60' with drag radials and no tire spin. I couldn't get it to hook when I would flash it off the line so with some slicks it could be in the 1.5-1.6 range. It was only my second time to the track and I think with more practice I could get it down another tenth or two. My vig is a 3800 but I only have 3.23 so I can't wait to get my 3.73s in it.
