which converter for my cam? i have a tr230/224 cam in my room and am installin it very soon, but i need to choose a stall. the car is my DD so ET times aren't my concern and right now i could careless about them . . . but i know i'll need a stall with this cam. so my 3 options i'm thinkin of a the TCI Super Street Fighter Torque Converter 3000 Stall Speed 2.2:1 STR from LS1speed, the YANK STEALTH THRUSTER 3000 stall 2.25 STR from yank or possibly the YANK SUPER STOCK 3200 stall 2.1 STR. what do the items in bold mean and refer to and which one would you guys reccomend? thanks in advance

TR230 with a Yank PT4400 here. The converters you mentioned are kind of small......you should really consider a SS3600 or SS4000 for that cam. The SS series converters are very tight for their size and make great daily drivers. Hell, my car rarely sees the track and I still wouldn't have anything other than the PT4400. It drives great and pulls like no tomorrow.
The numbers in bold are the stall torque ratio...the higher the number the tighter the converter will feel, the harder it will launch and supposedly the less efficient it will be. I don't believe the efficiency argument all the time. IMO, if you stay with Yank or Vig you can rest assured that you're getting a quality, efficient product. My PT4400 has a 2.5 STR. The SS4000 has a 2.6 STR and I'm not sure what it is for the SS3600. If you do a search, you'll find that the SS series are hard to beat for all around performance and driveability. If you want wild and max-effort, look at the PT4000.

like i stated in my first post et times don't mean much to me right now cause it's my dd . . . so racing people is something i don't give a **** about at this point, i just want a stall that will enable my car to drive so a 3600 or bigger to me is a waste of time even lookin at since i will not purchase it, my original question was regarding to the 3 i stated. please stick on topic or don't post, thank you for your opinions guys but i will not be lookin at big stalls

For the same price as a small converter, you can get a larger one that drives just as well and offers much more performance. Converters don't just make for a better track car, they make for a much better street car too. In my case, more so as a street car since I don't race that often (track too far away). On top of that, a smaller converter can severely limit the potential of a cam. I was told by many members that the best choice for a cam in the 230's duration is 4000 to 4400 converter. I started with a ST3500, upgraded to a SS4000, then after adding the TR230, upgraded to the PT4400. Unless I decide to spray some day, this will forever be my converter of choice. It absolutely rocks in every way.

why even put the cam in there if you don't want to "race" or go fast?
That cam isn't going to be making much power at 3000. You wouldn't be in your power band at all. Go bigger or sell your car.

99hawk: i didn't mean to come off as a dick, but like i said i really don't want a big stall as this is my DD bgger the stall more gas i'm burning. now i wouldn't mind it if i was just driving it for my weekend fun driver and runnin people at the strip but since i'm not a 4000 would definatel be a waste
socmguy: i know alot of people who have fast f-bodies, vettes and cobra's who don't race them, just cause it's goin to have more hp doesn't mean i need to race it around. my driving habits are 7 miles to the freeway in stop-n-go traffic and if i'm lucky i'll hit greens, then it's 20 miles of open freeway and than 1/2 a mile to my work. how i choose to drive my car is my choice nobody else's, so really if you don't like it you can simply not post in this thread.

Sorry to be so harsh but you did come off kind of "dickish" to 99hawk. I just don't understand why you'd even put a cam in an A4 LS1 car if you're concerned about gas prices/mileage. I won't post in your thread anymore.

The reason i went with such a big one is that I wanted a solid 12 second car with as little parts purchase as possible. Big stall + gears + a catback (for sound) gave me that. But thats just what I wanted, and maybe if you went with a bigger converter, you may not want/need the cam.
Like the second poster said he has a 3200 and it seems fine to him and I'm almost positive you wouldn't be disappointed with a smaller converter, but why not get the best match?? I really like to read what 99Hawk262 posts because his are the ones that pushed me over the edge and got a 4000.

i'm not so much worried about gas price really, just mileage and the bigger the stall and it's almost a definate from what i've been told about having to change my gears and i'm very happy with my 3.23's. the biggest i'll go is 3.42 so i might just end up doin the 3600 i really dont want to go higher than 3.42's in the rear

A "rule of thumb" on converter choice is to choose a converter that has around 3000 usable rpm above the converters rated stall. Example: Engine will produce power to about 6500 rpm.......choice in converter should be in the area of around 3500 rpm. 3500 stall + 3000 usable rpm above the converters rated stall = 6500 rpm. A good choice for that cam would be a 3600 stall with a 2.5 str. Your converter will be a lockup unit so highway milage will not be an issue. Run a aftermarket trans cooler and everything will be fine! Listen to the sponsors. They will not mislead you.

King, technically the converter is based on the cam specs @ .050" duration on your cam card, plus alot of other variables. The converter companies should help you with this. I have noticed the LS style motors are unorthdox to this. I chose a 3200 Vig and it worked fine. I ended up with a 4000 stall, (the free 2 year restall), and there was no difference in daily driving except a little more slip off the line. The torque multiplication is so good today, you can run a higher stall and not ruin driveability. I have a 10 second car and get 24 mpg if I don't beat it hard. Do your homework before you buy, and buy quality the first time!!! Hope this helps.
