Circle D Review
Circle D Review I thought I would post on here and give my experience with Circle D and thier converters. Recently my stock trans in my 96 t/a bit the dust. Since I already had a built motor with a larger cam I decided while I had it apart this time I would get a higher stall to go with the rebuild. I called around and talked to a couple of other vendors before I spoke with Chris at Circle D, the other vendors wouldn't return calls pm's etc. I pm'd Chris and told him what I had and what I was after. So he recommended a stall for me. I made a phone call and spoke with him on a thursday and monday dhl dropped it off. Very fast responses and getting it shipped on thier part. I even got to talk directly to a person when I called instead of a machine and waiting to hear back, which is a big plus to me.
Anyways, on to the results. My self rebuild went very well (not my first by a long shot). I spiced up the shifts with a few mods here and there while I was at it. What I told Chris I wanted was something I could drive every day with a full sized lockup clutch that would do well in traffic and track results were not the priority. He suggested a stall they have for lt1 that would be in the 2700rpm range. I have driven alot of stalled cars before, and this is one of the nicest driving stalled auto's I have been in. After a tank of gas or so I cant even tell its there when driving normally. And when I hammer it the flash hits about 3000rpm before it takes off, and what a smoke show follows that. It hits HARD. I wasnt expecting much because of the lower stall speed and the large size housing, but I was wrong. It takes about 1700-2000 rpm to move along a little faster than traffic, it pulls just fine when you take your foot off the brake. The lockup clutch apply is also very good, feels like another shift when it engages and after that its just like stock. I am also happy to report that passing somebody is also a whole lot more exciting now
.
I did pick up a substantial bit of performance. I took it to the track after street driving the car about 500 miles. I bolted on my slicks and skinnies for the track after a couple of street tire runs which were pointless. Before the car ran low 12's bogging due to the stock stall best being a 12.1X. The first pass with the new stall was 11.7, after some more runs figuring out how it liked to launch I got two back to back 11.5 passes. I think I may be able to get a little more from it with more tuning and shift point adjustments. I also picked up 2mph for 118mph traps now.
This is not a race car, I drive it back and forth to school 50 miles one way 5 days a week (500 miles a week). I have seen many people talk of ordering them but not alot of reviews yet so I thought I would tell my experience.

Man those Circle D converters are looking very good. I just stepped up from a 224 cam to a MS3. I think my next mod will be a 4000 stall with a triple disk clutch from my current 3600.
I appreciate it and glad you love the converter.
