Scared to go from Yank SS to the PT
With the right weight it would do this.
Magnus --------- 10.987 @ 119.31 (1.42), 97 Firebird A4, YPT4400, 4.10, 2920, 12/04
Matt D --------- 11.421 @ 116.24 (1.47), 99 Camaro Z28 A4, YPT4400, 3.73, 3100, 11/07

Shouldnt be that hard,OK ,Since you wont let this tread die im gonna chime in one last time before it gets locked.You can pm Matt D and ask him why he was kinda ticked when he ran his 11.42 at about 150 lbs lighter than Chris 11.55 ss3600( same day and track) and was only 1 tenth faster than him with his 13-15% slipping pt4400 at an identical MPH.His converter was looser than mine and he knew it.Both of these cars are alot lighter and have not run in the 1.30s.I was there also helping Mangus run his 10.98 along with PSJ. THERE YOU GO!!! LOCK IS IN ORDER!
I don't give a **** about PT4400, that post was for TA1364. You must think that you're the only ************* that can go fast, huh? You got some magic that ain't nobody else got.
I don't intend on running anything cam only. Since I already have a set of heads ready to go. If I were so intent, I don't see 10.8 as being a problem with a similar sized cam.
I hope you circle D stall works out well for ya.

He's trying to compare a stock internal 60's to cam only 60's to prove some off the wall point that isn't relevant here. Like father, like son.
And then he wants it to get locked so he don't look like an idiot.

went from pt4400 to circle D gained .5 ET and 6mph..., cam change i think was a g5x3 to a g5x4...
haha also makes 405rwhp with a dynojet...guess those dynos really are a good means of comparison between cars...
we are both comparing things that we dont have first hand knowledge about because neither of us have swapped out one converter for another (pt4000 for ss4000)...so it is a pissing match till we do...
which converter do you think is better in the above thread?

He also mentions that his PT4400 was 5 years old and wore out and that it had noticeably lost shift extension.
So a custom 8 inch non-lockup converter and a cam change and he went quiet a bit faster. What the **** does that have to do with this conversation.
Congrats to him though and his new converter. That's fast, no doubt about it.
And you're right, we haven't ran both back to back to compare them as they need to be. All the more reason to take the word of the guy who designs and builds them, if you ask me.
The higher STR (~2.6) of the SS series makes it 60' and ET better then the softer STR (2.2) of the PT series. Althought the PT is more geared towards roll racing or trapping higher MPH. I know the SS uses the more efficient 21-blade GM stator found on newer application, versus the PT using the 19-blade (IIRC). A converters ability to 60' has more to do with the STR then the stall speed. It is obvious why the SS can out 60' and ET the PT converters.

If anybody's interested, I'd like to help settle this debate. I've got a 2007 Corvette that I just put an LS7 in and I'm currently running an SS3600. After hearing about my engine swap, Dave suggested the PT4000 so quite possibly as early as next weekend I might have some good comparison numbers.
I ran last night in Sacramento but since they don't prep with VHT during the week I had some traction issues but even then I was still able to pull my best ever 60ft of 1.546. My current plan is to race at the Test & Tune this Saturday (weather permitting), pull the converter and ship it back to Dave, have him convert it to a PT and then reinstall it and run again next weekend. I think that would be a very good apples-to-apples comparison because my intent is to not change anything between this Saturday and the next one except for the converter so I'll have a pretty good idea of how much it helped out.
I currently have the converter coupled with 3.42 gears (my car's an A6) and it is extremely streetable and in fact, I've had several different people drive my car and they've all commented on how it didn't even feel like it anything other than a stock converter in it.
Dave did mention that I *might* start to feel a little sloppiness with the PT but I figure that's a small price to pay for getting better ETs.
If anybody has any questions feel free to PM me, otherwise I'll just post up the results once I have them.

Now if you have too much power and need a softer hit, then go with the PT and MPH better.
My take. Depends on the car.
