Vig 3200 to a PT4200 results? I have a 3200 Vigi now and a PT4200 that's upstairs. I want to know if there is a huge difference in drivability or not. Also, what kinds of gains can I expect from the swap? Is it a PITA to launch? I can hook the Vigi now on the street, but I don't know about hooking this Yank. Ha. I also have 3.73 gears. Thanks.

I went from a Vig3200 to an YPT4000 and then back to the Vig3200. Yes there is a huge difference in drivability. The PT converters (or any high stall converter) are a very loose converter. When you leave from a stoplight you will be turning 3000+ RPM to keep up with the traffic. You will have very little part throttle response. Also my gas mileage went to crap with the PT4000. After the converter clutch locks up the car will drive just like stock. I much prefer driving the vig3200 around town. FWIW both converters will spin the tires from 50mph which is kind of fun to do.
I would never have a 4000+stall converter in my daily driver car. I just would not be able to tolerate it.
Now at the track it is a different story. The YPT4000 stomped the Vig3200 butt. And it should.
Stock internal motor:
Vig3200 best was 11.92 @ 113.3x
YPT4000 best was 11.79 @ 113.9xx
Heads and cam motor:
YPT4000 best was 11.18 @ 120.5xx
Vig3200 best was 11.35 @ 117.8xx
Both converters would cut 1.52 – 1.57 60-foot times.

Hmm. I see. I drive the car a few months out of the year, but just how bad was it? What size gear are you running? Was the Yank a lot harder to launch on the street? Thanks.

I went from a Vig3200 to a PT4000. There was hardly any difference after adjusting my shift points. Gas mileage is about the same. So far I haven't run much quicker with the PT4000, but I've only been to the track once with the new Yank. I don't think it's any where as loose as John describes. Mine was a daily driver up until a few weeks ago.
