Question on TC stall speed
For all you TC gurus out there....Is 3000 too high a stall speed for a GS400? I know most of you are using 2800 stalls. Would using a higher stall speed adversely affect the way the car runs or is the higher stall speed negligible? Engine is stock. Any help would be appreciated. Thanks.

If I had a GS4, I would get the 2800 stall speed. It seems that people are smoking their tires with the 2800 stall speed as it is. Anything higher would probably be pointless.

3 reasons to go with 2800
Before I got my P.I. TC I did some research - in addition to a lot of general stall speed info available on the web via a Google search, there’s probably a couple of hundred posts about the subject available via the CL search. But I can summarize why I chose 2800 as follows:
1. Mo, the CEO at Swift Racing (SRT) said “For a 430 we recommend a 2800 stall and keep the stock 3.26 rear and replace the spider gears with the TRD clutch type LSD.” The same applies for a 400. That is apparently a pretty ideal setup, Mo oughta know.
2. I personally called Precision Industries and discussed my NA GS400 with a guy that was pretty knowledgeable and was told the 2800 was what I needed.
3. The vast majority of the members that already had TC’s on CL had 2800 with no problems. There are relatively few with a different stall speed.
So, my 2800 Dragon has been spinning my S-03’s for almost a year now with no problems. No check engine lights and excellent driveability.
My .20 cents worth.

If you go higher than 2800 on the GS400/430, your tranny is going to be hunting gears more with rpms going up and down a lot on less than wide open throttle. Not that great unless you're on a track.

sorry for asking the dumb question, but I've been hearing about auto tranny stall speed for years, and I never quite figured out what it was, would someone be kind enough to enlighten me? From what i've figured out, raising the factory stall speed somewhat helps launches on autos.
