Well...Ive got almost everything that I need for the swap, except a converter and a few other little things. Its time to decide! I visited Yank's site and boy... am I stumped! There are so many different series of converters. How do I choose the right one? As far as I know, I want good effieciency, high shift extension, between 2.5-2.7 STR, and a 3800 stall speed. The car isnt a daily anymore, but most of its use will be on the street. I want it to be fun to drive, yet when I take it to the track, I want it to do awesome. However, I dont necessarily have to dominate at the track, so I dont need a race only converter or anything outrageous. I dont want to over do it and dislike driving it on the street. I havent driven the car in months, so I dont have any idea what kind of gas mileage its getting right now, but Im thinking that I dont want this converter to drop me any lower than 12 mpg in the city. (will be using a 200-4R if that has any affect on the gas mileage.) I hear a lot about looseness and tightness...Ive never owned a automatic sports car, so I wouldnt be able to tell one from the other, so Im going to say that it really doesnt matter as long as it doesnt drop me below 12 mpg in the city. I figure, the looser, the more gas it takes to get the car rolling, which results in poor/worse gas mileage. Thats pretty much all that I can think of as far as the converter and what I want in it, so if you could point me in the right direction as far as which one to get, I would really appreciate it! Im so ready for the conversion...I never thought that I would ever get this far! I figured that I would of backed out a long time ago, but its definately a go!!! Thanks

For the umpteenth time, you CAN'T go wrong with the Yank Super Stock 3800. It has all the attributes you're looking for. The board members here have given you solid advise. Go with it.

According to Yank's site, it says, "for maximum ET and mph running naturally aspirated, choose a converter with more shift extension. The SS3800 has 4900-5000 rpm shift extension." Im no expert, but for an naturally aspirated car, isnt that kind of low? It also says, "bottom line, for cars with less gear, smaller cams or power adders such as nitrous oxide, less shift extension can be better." I'll be running a 3.42...is that less of a gear? Im running the MTI C2 cam (224/224 .581/.581 112)...is that a smaller cam? Lastly, I wont be using nitrous. So therefore, I take it that I would need more shift extension which the SS3800 doesnt offer. (4900-5000) I read up on that particular converter and its seems to be a nice converter, but it'd be more for me if I was running a 2.73 gear and some nitrous. I dont want to have to step up to a really high stall speed to obtain the high shift extensions, so what are my alternatives? Thanks

Listen, you seem nice, but you can't take a hint. More shift extension = more loose. You say you want to go fast, but you want decent street manners. Converters are all about compromises. You can't have it all. Shift extension for a stock converter is around 4000 rpms so 4900-5000 shift extension in an SS 3800 is a nice gain for a converter that has good driveability.

Stop dicking around with the questions. We've given you the best advise based on your mods and your goal. The SS 3800 is the best converter made by Yank that meets your goals. A Vig 3200 would be the best converter that meets your needs made by Precision. The TCI SSF 3800 would be the best thing made by them. Buy something and enjoy it.

Maybe you need to drive a car with a 4000 stall to see how loose it is. Some folks don't like it and it bugs them. The off-idle response can be described as soggy.

Other folks like me like going 1.4 short times off the footbrake.

If you rarely plan to go to the track, and you think a loose converter would bug you, go 3500 something. If you want max performance for a street car get a 4000.

Patrick G, as I stated in the thread starter about looseness and tightness, "Ive never owned a automatic sports car, so I wouldnt be able to tell one from the other, so Im going to say that it really doesnt matter as long as it doesnt drop me below 12 mpg in the city. I figure, the looser, the more gas it takes to get the car rolling, which results in poor/worse gas mileage." So to have more shift extension results in a looser feel, thats fine, as long as it doesnt drop me below 12 mpg in the city. Gas mileage and being fun to drive on the street are the only 2 things that I care about as far as "street manners" go. I dont care about racing on the street, from a dig or a roll, the car will only be raced at the strip. I realize that a SS3800 has about a 900 to 1000 rpm shift extension gain over a stock converter, but is that going to keep me in my power range? If my car is shifting at 6500 and I have a 4900/5000 shift extension, thats a 1500 rpm drop! Isnt that a lot for a N/A car? I hate to ask all these questions, but I just want to make sure that I get the right converter because I cant throw around $1000 like some of you on here can. I dont have the time, money, or the job to be constantly swapping converters. I really appreciate your help!

The best advice I can give you is to dyno your car in race setup and send the dyno chart to Yank, Precision, or etc., and ask them to design a converter specifically for your car. Otherwise, you will be guessing.

Even if you got the baddest of the bad, the Yank Pro Thruster 4400, your gas mileage is not going to drop below 12. Mine always averaged closer to 14 in the city and 23-25 on the highway (with 3.23 gears) when I ran the PT 4400 in my Z-28.

Sounds like you're shifting gears on us with your goals (more strip than street, more shift extension). That said, go with a Yank Pro Thruster 4000...no question about it.

Colonel

NV, you're getting yourself a little too worked up about the shift extension. A 5000 shift extension is not bad. My TCI 3500 only gave me a shift extension of 4900 and I ran 11.82 at 113 MPH with the stock cam. Last weekend I ran 117 MPH with the Stealth II cam and this same converter in not-so-great weather. Remember, this car is pretty close to stock weight and has 3.23 gears.

Would I have gone faster with a TCI 4000 and a 5400 shift extension? Sure I would have...and the car wouldn't be as drivable as it is now. Like has been said before, more shift extension = a looser converter. It's a tradeoff. You have to decide how much streetability you're willing to sacrifice for performance. Driving someone else's car with a 3500-4000 stall would be a very good idea, as mentioned by PSJ.

My next converter? I have an SS4000 on the way. It'll give me a few hundred RPMs more shift extension and I'm hoping the drivability won't be effected too much for my tastes.

Nv, you just have to decide what you want. You really need to see what a 3500 - 4000 converter feels like to know what we are talking about.

If you are 75% racing then get a Yank TP4000. About as big as I would go for a daily driver and it would go low 1.5's at the track.

Im not really shifting gears, I just elaborated a little more on what I wanted. I hate to throw this in the air, but what about the new Yank converters, I believe its the PS series. How would that particular series fit my attributes? Are they even out yet and if so, what kind of results? When will there be info on them on Yank's site? Now that I think about it...12 was a pretty low number. If I can remember correctly, I was averaging about 15 to 17 in the city, so Im gonna say no less than 15 this time around. When I first had the thought of going to an auto. I wanted to go with a 3500, simply because it sounded like it was in the middle. I never even browsed the automatic section or looked into it, that number just popped in my head. Well as time when on, I figured that I might as well go a little bigger because I see everyone wanting to step up. (ex: 3200 users to 3500, 3500 users to 3800, etc.) So I figured that a 3800 would be perfect, but that was my limit. The reason it would be my limit is because I thought that anything above a 3800 was going to really hurt my gas mileage. Even with a 3800, I thought that I was going to see between 13 and 14 mpg in the city. As time goes on, Im starting to drift off and not know what I want. Im sure of some things, but theres things that Im not. I know that I dont want a converter that Im not going to enjoy on the street. I know that when I take it to the track, that I want it to do awesome. I know that I want high shift extensions because I'll be running a 3.42, a mid range cam, and no nitrous. Also so that I dont have too big of a drop in between shifts and so that I keep in my power range. I also know that I dont want poor gas mileage, and I know that I said before no lower than 12, but Im shooting for 15 now. I want a good STR, around 2.5-2.7 for a good hit off the line, but not too much. Lastly, high efficiency for good MPHs. I hate to blabber on and repeat a lot of what I said already, but I wanted to word things differently, so that its more understandable. Its kind of hard knowing what I want when this is my first time to ever to buy an aftermarket converter, much less drive a car with one. I do appreciate everyone's help.

Yanks new Pro Stock series sounds interesting.

Do a PS3800 and go from there.

If the gas is too soggy feeling have it destalled 400 rpms.

Sounds like you are trying to find the girl you are going to marry before you've even gone out on your first date! You gotta try stuff before you are going to know what EXACTLY you want, so as was said above, take the best advice you have received and make the dive. This isn't life or death here, its a car part.

As Samuel L Jackson once said..."SAY 'WHAT' ONE MORE TIME ************, I DARE YOU".

Colonel

No such thing. The PS line starts at 4000.

The SS4000 might be your cup of tea with a respectable 5300 shift extension if you want it to still be nice to drive everyday. It'll hit hard enough to get you some mid 1.5s for sure. The PS4000 will get you 1.4s but you're going to need serious TRACTION and streetability is going to suffer as compared to the SS. The SS will be the most streetable of the 4000 stalls, followed by the PS, and then the PT which is as loose as bordella women. The shift extension will go in opposite order. PT, PS, and the SS having the lowest. From a roll racing and dragstrip trap speeds will also go in this order because of the shift extensions. Hardest hitting off the line order is PS, PT, and then the SS.

Just flip a coin.

At one point in time, there was a lot of talk about the new PS series, but Ive checked the 3 most recent pages and theres nothing. If I remember correctly, I think someone was saying that they dont offer the 3800 in the PS series. I checked Yank's site, but theres nothing on there about 'em. Hopefully someone will chime in and share some more info about them. Thanks

Colonel

We posted at the same time.

Well...the PS4000 and the SS4000 seem to be the two that I'll be juggling now. I wish it was as easy as flipping a coin! The PS is going to have a higher shift extension, better trap speeds, and hit harder off the line than the SS, but it will be a bit looser. Hrmm...how loose are we talking? If the only drawback to having all those pluses is the looseness, then I might just have to go with the PS. Colonel, are you absolutely sure that they make a 4000 in the PS series? Besides all that Ive mentioned about, what other advantages does the PS series have over the SS? What do the PS series go for? ($) When will there be info about them on Yank's site and when will they be available? Thanks everyone for your help, I really appreciate it.

Colonel

Yes, the PS line starts at 4000 according to what Mike Senia told me.

How much looser are we talking? I honestly don't know. I'm going with the SS because I like the drivability of my TCI 3500 but I need more shift extension for this cam (by looking at my dyno sheets.) I figure that the SS4000 will give me just enough SE and will be as, or almost as, streetable as my TCI. We'll see.

I've mentioned every advantage that I know of. The new clutch that the PS comes with, the SS also now comes with (per Mike on the phone with me today.)

I don't know when the info will be up on his website. Patrick G probably knows (if you can still get him to talk to you!)

The SS is $895. I suspect that the PS is $950 but I don't know for sure. They are available now I think. I know Mike offered to build me one at least.

Between the SS 4000 and PS 4000 the Pro Stock will be a better track converter. As far as looseness there is hardly any difference,i would think. If you go with a pro stock be advised that it cuts some good 60fts. I have only been to the track one time with mine and was having pcm problems because of running 3.73s instead of my 4.10s but i was still cutting 1.55s easy on a crappy track. Either way you better have some tires!

Does anyone know when there will be more info on them on Yank's site, when they will be available for purchase, and what the pricing will be? I havent seen Yank post anything about them lately or anyone for that matter. They arent having problems with them already, are they? How many of you are running one? Thanks
