4000SS or PT for first TC? I've been going back and forth about this for a week, I plan on ordering a TC but am not sure if I should go with a SS or PT series. The car is strictly a street car and I will be adding a Speed Inc SI5v2 cam, I already have 3.73's in the rear end. I'm just not sure if the PT will be too loose for the streets only? Thanks
basically, the ss is a good street converter that'll perform well at the tack and the pt is a good track converter. IMO the ss will be plenty for you since you said its a street car. I have an ss3600 in my car and for how i drive, i think its perfect.

I was going through the same situation recently. I ended up going with a PT4200. Reason being the car is not a DD and if I'm going to pay that much for the converter I want it to hit hard as hell. Performance was my final decision.

It seems almost everyone recommends the SS for street use and the PT for track use. Thanks for input guys I guess I will order the SS I haven't really read much stating the PT has any real benefits for street use other than having a higher shift extension.

Verdad Gallardo That's why I'm doing the E series from Circle D... same basic premise. Hits softer off the line and is more efficient when moving. Plus, the added shift extension makes up for a lot too, especially when I am expecting just an 800 RPM drop in my setup...
But, the downside is, it's looser. Needs more RPMs to get moving. Once locked up tho, doesn't much matter. Will flash up and unleash hell.

Now I'm back to the drawing boards those are some good points about the pt. Any idea what kind of rpms i would be turning with the pt to get moving vs the ss? I have 315 NT05R's on the back so traction is usually not too big of an issue but they do spin sometimes.
No, I'd do the PT4000.
I would say you're probably going to see 2500rpm to get moving with traffic or therabouts. 3.73 is a good match for the 4000.
SS4000 would probably be a couple of hundred rpms less.
On a side note, how are the NT05Rs? I've really been thinking about those. I love the NT05s I have now, but they are easy to blow away. I just worry about torrential rains and high speed handling/cornering. Kind of torn between those and going with something like the R888s.

I love the NT05R's but I honestly don't have much to compare them to. The only other real performance tire i've had was gsd3's on stock wheels. brand new though they were pretty ridiculous they wouldn't spin whatsoever just take off but every once in a while now I get them to spin from a stop and I had them spin on me on a freeway entrance flooring it but that may have just been the road itself. I do like the fact though they are only like 200 each.
These converters are going to drive me nuts. I mean I hit 3000-4000 rpms or so right now just taking off like a jackass, when I get whichever converter is it basically just going to slam me into the seat doing that?

So Chris is taking care of me.
I can't wait to get it it.
On paper the PT4000 is supposed to be better. From a roll it probably is slightly. But it's looseness is what would keep me away from it if I went that route and I would've done a SS4000 because it would out 60ft it.
PT4000 out 60s the SS if you look at most of the fastest times. Just overwhelming the tires at the start won't make you faster. And even if you out 60 it, it won't be much. The PT could easily reign it in on the big end.
Now, the SS would be better for 1/8 I think. The efficiency is less of a concern there. And it still drives better.

I think that list is bias since it's cam only so it makes more sense there are more PT4000 times with good 60fts.
PT's are pretty loose on the street, I'd rather have a tighter SS unless I was running a decent gear to take advantage of the PT4000

Not to diss the internet mechanics we have here, but have you spoken to Dave @ Yank about your combo? I pulled my trans (unrelated) and was going to swap over to a PT series converter and he talked me out of it. Meaning he lost a sale bc he felt my car had the right converter in it already (SS4k). Food for thought gentlemen.
