which of these three converters? well, i made a date for an FLP trans. now i need a converter to choose. my choices-
Vig 3600-3800
Yank SS 4000
TCI 4000 (dont know what kind)
im keeping the stall kinda low since i have a crap rear gear for now. ive had a vig 3200 and a pt4400....hard to compare the 2 brands.. the yank broke though lol. im trying to get an idea of whos had good luck with one of these three. the vig i had was awesome, but it didnt do much on the expressway compared to the yank...then again it was tiny compared to it. and quite a bit cheaper
just recently thought about a tci. ,no experience with them. any opinions. thoughts, etc?
Edit- i changed the yank from a pt4000 to an ss4000.
Vig 3600-3800
Yank SS 4000
TCI 4000 (dont know what kind)

I think your choice of STR depends on the tires and gears
and whether you favor hard launch over top end efficiency.
The stall speed follows your powerband and the degree to
which you care about having low RPM acceleration in city
driving. I think it's the STR choice that you have to do
the thinking on. That will probably narrow it down for you.
I see pretty high STR on the TCI4000 and that might just
be insane for street tires or drag radials on a daily driver.
I think you will find a more efficient Yank available than
you can get from TCI and probably PI. However their
selector guide has really gone downhill (or, just plain
gone) so you might have to talk to a live person to see
what of their former product line is still available and
which might be more efficient, what STR options there
are in a 4000-ish stall speed etc. Maybe PM Dave@Yank
if he doesn't jump in here on his own.
From the look of the mods & times I'm thinking one of
the Pro Yank series might make sense. You're going to
be beating on it, might as well go for the gusto and the
top of the line guts. But I don't know whether you can
also get good street efficiency / low throttle drivability
in that line or at the stall speeds you're looking at. Or if
you even care.

well, my setup right now is kinda goofy. Ive demodded somewhat. well, the only power mods i dont have anymore (From the times in my sig) are headers. I am back down to a 2.73 gear, for now. i am cammin though and the car still mphs pretty sick for the setup. I want to get a trans/converter in there that i can keep for a while....aka, longer than a couple years lol. ive put too many stock trans in this car. i want a built one, and a converter than i can carry over when/if i get a new rearend. the yank guide is kinda useless. i dont have ported heads, and it doesnt have a cam only setup.... i have milled stock ported heads so my engines a little torquier (off idle) than just a plain stock head...maybe i can get away with less str then <shrug>
whats the difference between the SS series and the PT series? all i see different is the STR (which the ss is higher), but it costs less. says nothing about the clutches (which is what went in my pt4400).
my low gear says that the TCI with a high STR isnt a bad idea. i dont know what the vig is, but my vig 3200 netted me a best of 1.47 on a pretty heavy car. that was a great converter, just didnt have what i needed with the cam though. i hear vigs are bad with their effiecency, is that because of their higher str or what.
and everyones idea of streetability is different. i had no problem with the pt4400 and 3.73s. i mainly drive my car on the weekends now anyways, so i dont care how aggressive it is. the more the better.

the ss4000 is a better chioce with that rear gear, and is about all you will need as you will get the extra push off the start (STR) and the top end will be great also (less slip)
the clutch in the SS is an extra hd design and will hold up!
it is NOT a carbon material as in other mfgs converters
carbon lining is made to slip by design and will slip around 3-5 % under lock-up, even with high line settings
our new clutch will lock up with no slip!

but with 3.73 at the 1/8 mile mark they will be close with the ss having the edge,
at the 1/4 mile mark the PT will be ahead by 1 car
again with 3.73 gears
Yank uses all NEW parts in the SS and PT converters that we get from GM or make ourself,
not salvage cores as other co.'s use in their builds, that is only one reason that our converters are in some cases a little higher in price but even with the cost of steel up 300% in the last year, we are still in the same price of $775.00 on the ss.
And we use more custom machineded parts in our product!
you get as always a top quilaty hand built product from YANK and we have a 2 year warrenty

I've had 2 TCI's in 2 different cars. I'm fixing to upgrade my current one to a TCI 4400. Basically I've had 0 probs with TCI. They run great, perform when they need to and they are easier on the pocketbook.
Get the PT for 3.73 gear and higher if you dont mind loosness on the street. I run the PT4200 with 3.73s and its a monster at the track. SS is street friendly and the PT is track friendly. It just depends on you tolerance level.
I ran a PT4400 with 2.73s in my red car for a while, before I got the 9". It was LOOSE, but worked well, wasn't totally undriveable, just looser than with a gear. Go big now, imagine what your car would have ran if you'd had a more agressive converter.

well, i dont see myself getting a rearend until atleast next year. a year is a long time for a loose converter that might suck with the setup. i dont even know how much im gonna get into racing (at the track) anymore. now i have a mortgage 
and it seems to take precident over the car nowadays. lol. hell, if i like the 2.73s and converter i may just keep that setup. how many people break 2.73 rears anyways hehe. god knows ive broken enough stuff already on this car.
