Circle D question

[cer0413]

Since I've decided on a forged rebuild, some buds of mines recommended a torque converter since the engine will be out. I researched some signatures lines and garages here and many centri setups are running a 3500-4k stall speed. I don't know the difference between stock vs aftermarket stall so hopefully I can gain clarity from you centri guys about your usage. My car is officially retired as a DD but I still plan on driving it a lot. (weather permitting) What stall should I purchase based on my needs before pulling the trigger?

Street Drivable
Mild track use
highway use without hurting gas
Parallel Parking

I spoke with Brian from circle D and he recommended the
Ford 245mm Pro III 4R70W Torque Converter. (3c stall)

I have a Precision Industries in mine. I believe it's a 3500 or 3800. Contact PI and talk to them about your plans. The stock is 2800 I believe.

[Lowndex]

I have owned both Precision Industries and Circle D torque converters. Circe D is far better.

Like this guy here. He has a PI 2800 stall (same as you) with a vortech kit and he landed 10s in the 1/4.

Stock stall is not 2800 I don't believe but more like 2000-2200. Yes they will flash higher . Cv Intercrptors were like 1800 stall. Roots blowers don't need super high stall ones. The power is built low anyway. Mine is a PI 2600 stall and my torque and power curve jumps right up and holds across darn well. Some of this info was from Lidio if you search the archives.

Will do. What stall was in your last build?

[RubberCtyRauder]

My centri was stock. Centri blower can use a higher stall since it's power band starts higher than roots style. Everyone had their own preference. I'm just repeating some of the stuff I've read here in the archives. Some like high stall on roots or twin screws.

[Spectragod]

I'm using a 2800 stall circle D triple disc with a twin screw. Works for me, may not work with your mods though.

[MOTOWN]

Get a Circle D 3500 triple disc , and you will love it with a centri!

I have had a PI 3,500 Stall with 100K miles, ~100 1/4 Passes and 540RWHP.
Resently sent it in to PI for inspection and it required NOTHING!

As far as drivability it's all in the tune.

I have a 3K stall because I was doing daily driving and a few track runs. It drives like stock until you put your foot to the floor from a dead stop. It also works nice with the trilogy when I can hook up. Some people complained that the 3500 stall felt too loose for daily driving.

What's loose? I here that often with this mod.

luckily both PI and Circle D gives you the option of changing stall speeds within a year but I found this.

"Too "loose" is when the stall is too high for the car's combo...like for instance when I had my old AOD and 3800 stall converter in my 94. That converter was perfect for my blown 86 due to 200+ lb/ft of extra torque that allowed me to make full use of the torque multiplication that the "looser" stall speed gave me. The 94, being a much slower and naturally aspirated car, that same converter was actually too "tight" at the track, yet too loose on the street. Why? Because it simply was the wrong converter setup for my combo.

I know you guys have heard the term "flashing the converter"...that "flash stall speed" is basically where the engine will rev to while cruising along in high gear and "flooring it" quickly and letting off. The rpm you see at that "flash" is higher, if the converter is looser, and obviously it would be lower, if the converter was "tighter"...For reference, my 86 "flashed" to 4200 rpm's...The 94 "flashed" to 3000...maybe less. That is why I always recommend getting a converter "custom made" for YOUR car (if at all possible), instead of going by the assumption that a 3500 stall is going to be a 3500 stall in your car, because it was a 3500 stall in Joe Blows car...If your cars aren't nearly identically prepared, the stall will vary...like in my case, it varied alot...IN a perfect world, the converter is not slipping excessively when cruising on the street, yet has that high "flash" stall to get it rocking and rolling off the line.

If you got a converter "tightened up", it would mean getting the stall speed lowered, and getting it "loosened up", would mean raising the stall speed. The one video of Spence's car (I think it even says too tight converter or something), you can see the car takes off like a dog, then when it gets rolling, you can literally hear the engine come to life. That's a perfect example of a converter that was too tight for the combo he had. With my 86, they hit it right on the money first try, which was great (and lucky, lol), and with Spence's he had to send it back to get "loosened"...

As for "leaving off the converter", most people say it's launching at the highest rpm that you can keep the car from pulling through the brakes....Using my two cars as the examples again, the 86 could rev to 3200 rpm's and not move, if I held the brakes tight as I could. THe 94, with less power, would only "stall", or slip, to about 2000 before it tried to push through the brakes...What was kind of weird (I thought) was that both cars launched the best at neither an idle, or "off the converter"...The 86 loved 1800 rpm's, and the 94 seemed to like 1500 rpm's...To get the best 60 foots and launches, you need to find out what your specific combo likes...Mike morning launches just above idle, he says, because that it what his car likes...If I tried to launch anywhere above 2000 rpm's, I spun everytime."

This ^^^ is why you should call whomever you decide to get the convertor from to discuss your plans, how you drive, HP & torque, etc.

PI told me I need a 2800 stall for my needs and power. [emoji19]

[tbone]

I thought the stock stall was more like 1600. I have a custom built 3000 stall from Midwest Converters and it feels perfect for my Eaton swapped car. The guy actually took the time to stop by the trans shop to look at my upgrades and make sure he got it just right. Considering the engines sweet spot is 3200 rpm, a 3000 stall makes sense. 3500 probably would have sufficed as well, but I mainly wanted it designed for DD use.

I ordered the Circle D converter from BOC.

I had a PI both NA and with the Trilogy.
I did like the extra push off the line N/A , it just did not feel right with the FI.
It felt like the car had a shorter power band and felt actually slower.
Lonnie suggested 36-3800 triple plate from Circle D .
Every one here said , Too High!
To all the nay sayers.
I say don't fear the gear, or the stall!

You are a limited thinker, and I have over a ten year relationship with the man.

Forums are in place so others can base an opinion, I too have heard no so good reviews of BOC, I have never had a bad experience with Lonnie myself, I have in the past bought stuff for one of my Vic's from him. But that car was stock, I have not S/C marauder experience with him.

You continue to give enough time to weigh in and slam him every opportunity.
You have never even met him or had one instance in dealing with him.

I've mentioned him twice....only twice..I see no one else praising him like you do. I'm not basing my comment on one complaint, but more than a dozen in last 3 years. Once he was the man for panther upgrades but he has drifted away from those that seeked his services.
