Default pt vs ss

So pt 4000 or ss4000 on a bolt on car. Car currently only has 3.23's but will be going up to 3.73's. Car will have heads and cam by next year, but for now its just a bolt on car (true duals, lts, ported t/b, lid, etc). No plan on spraying the car anymore just to stay n/a. Probely end up doing a pretty big cam. I daily drive the car but can deal with things. Drove my friends ss4000 and it wasnt to bad. Currently the car has a pro torque 3k stall.

From what a couple of my customers have told me the PT series is better for NA applications. The SS is better for NOS. Hit up Matt D or 99Hawk262. I believe they have run both of these converters. Vince

The SS is the super stock series and the PT is the pro thruster right? I am an automatic newb and just making sure I got the acronyms right. I too sometime soon will be investing in a converter.

PM replied to but I'll answer here as well. I ran the SS4000 and currently the PT4400. IMO, the PT takes the cake hands down. It pulls harder from any speed and is significantly faster from a highway roll. I was shocked at the seat of the pants feel from a simple converter swap (and FLT tranny of course!!). OP, I didn't see that you were upgrading gears. I said PT anyways, but that will tighten things up nicely and make it an even better choice. For NA applications, look no further than the PT series. They are absolute monsters .

They are looser than the SS series, but with a gear swap I don't think it'd be that noticeable. Hell, I run mine with 3.23's and will be for awhile longer. It's not that bad, it just takes some getting used to. It was an obvious difference from the SS series, but that looseness is what makes all the difference from a highway roll. Shift extension on the SS was ~4900. On the PT4400 it's right at 5800 shifting at 6500 .

My times in my sig were first time out with 3/4 tank of gas and absolutely no car prep (i.e. weight reduction, front swaybar delete). Top that off with 3.23's and Bilstein suspension (tailored to handling, not dragging) and I was very pleased with my results. If you can stand a little looser and plan on staying stock cubes and NA, PT all the way!

Here's two videos from that night. Post #34 and the first video in post #43.

But for a car that is sprayed with more than a 100 shot the SS4000 is still the better choice right?

Yank does not recommend the bottle with the PT series. That's why it's touted as one of the best NA converters. If you're gonna spray, I'd stick with the SS series or PYE series if you're gonna spray a lot and often. Some folks have sprayed the PT's, but most have said it didn't work well at all.
