Who's running the I6 Stall Converter? Do they have the TBSS stock towing capacity? What's the stall speed? How do they compare to Circle D 278 which has a max towing capictiy of 4k & the Yank PTB3200? The truck is a D/D that will prob see towing once a year (my F-Body). Where can I find one besides GM Parts Direct PN#24228709? I apologize for having so many questions. Everyone inputs are welcome.

Contact Chris at Circle-D, many of us have had his product and it held up to everything I threw at it.

Do you mean a stock i6 converter? I would go to Chris at Circle-d. I got mine from him. Great to deal with, real nice guy to talk to.

Yeah the stock I6 conveter. I've read a few forums about them and it seems as if they hold up pretty good. I'll contact Chris tomorrow as far as in to detail specs.

May hold up OK but the stall speed is not that much more than stock. Really not worth the effort to do it.

Get a good converter like a Yank with a high STR.

I installed a stock one over the winter. To me it makes a noticeable diff in performance and feel. But, I think my situation is somewhat unique. I ran a 13.08 as "was". I only needed/wanted a tenth or two, w/out sacrificing much durability. I bought the converter for $248.00, and installation was free. If I was paying for installation, I may not have went so mild and made it more worth my while. For what its worth, I did make it to the track, but the tranny was bouncing off the rev limiter going into 3rd. Something it never did before even after the stall was installed and driving on the street. It was taken care of easy enough with a tune adjustment. But, even with bad gas and a not so well prepped track, my awd TBSS spun off the line (it's never done that before) and still managed 1/2 a tenth better 60 ft time. So, I think it makes a difference, and I like it.

My 2nd choice would be the Circle D. Just don't have the Yank money, wish I did though LOL.

That's what I've seen on one of the other TBSS forums that it's a pretty noticeable upgrade over the stock unit.

1/2 a tenth which usually means .1 in the 1/4.. iknow yank can be anywhere from - .6-.4.. i thought circle d with 3200stall should be able to cut atleast .2-.3 tenths in the 1/4. :2cents:

was yours a 3000 or 3200 stall?

If Circle D cuts .2-.3 that'll be perfect for the price. The only concern I have with the Circle D is the towing capacity. It's not often but I do tow my full weight F-Body every now & then.

Mine is neither a 3000 or 3200. It's a bone stock I6 converter, out of the box from the factory.

From what I can gather and was told, the stock TBSS converter is about 1800 stall, a stock I6 converter is 2600. I can't prove it, just what I've heard.

Thought I would chime in here to help...3 tenths is normal, some have seen more. Full towing capacity, but you do need to add an external cooler. Great bang for the buck and drive very nice for a DD TBSS.

You are pretty close. The OE TBSS is a 300mm, rated about 1600-1800. And the OE I6 TB is a 278mm rated at about 2400-2600.

Thanks for responding Chris. So the 278mm Circle D is the way to go for Full Towing, as long as I use and External Cooler(which is a must anyway)?

Yup
A lot of the truck guys get the i6 stalls to get in the 2500 stall speed range. They are pretty abundant at the savage yards so they go for as little a $80 to $100.

I will be picking up my Circle D tomorrow though. 3200 stall speed and i keep my towing capacity

Thanks Chris!

I ran a I6 TB stall on my RCSB, had great drivability, but was still a very good converter. I got it to brake stall to about 2500ish, AND I got it NIB for $150 shipped to my door.
