Got an E-mail from them today.

The 2005 Mustang converter is finally ready and available to sell. It runs $734.58 and comes with a 2 year warranty.

okay and what is a converter , or what does it convert?
can it convert my 300hp to 700hp that would be cool :jester:


oh wait a stall converter.... auto's.... didn't think about that

Did the e-mail provide a URL link? I don't see a Stallion listed for the 5R55S on their website.

I didn't see it on their web site either. Here's their phone #.

Hey guys a quick heads up. Alternative put one in a customers car the other day and it stalled to 4100 !! You may give it a bit or at least make sure they have the correct stall for your car. Other than that let the tire frying begin :-D

Thanks Mike

Ok showing my ignorance but I've been hearing about stall converters but have no idea what it does. Any gear heads want to enlighten the timid amongst us too afraid to ask?

Great link, George... just proved to myself how much I still have to learn about converters! :dunno: hehe

Just a bit of FYI.....if your going to put high duration cams in your autos(such as BBR's) you'll need a bigger converter.
Plus those guys at PI will custom make a converter for ya.

That is a hit for sure. George what is the stall speed? Are you purchasing one?

Ok, nice link thanks. I also checked out howstuffworks.com for more detail. If I understand it correctly, stall speed is the rpm the turbine and the pump are moving at close to the same speed? Do our trannies lock up at stall? If you increase the stall, you get more low end torque or do I have it backwards?

I mostly curious if this helps get a more direct feel from the transmission. I find it awkward to see my speed increase but my rpm's stay the same, not used to an auto.

Sorry if this is hyjacking the thread, not my intention, just trying to educate myself.

Thanks for input.

With my 2000 Camaro SS I dropped .7 off my 1/4 mile with a 3200 Stall and Nitto Drag radials, no other changes. It was N/A with Headers-back. 14.1 stock, 12.9 with the Headers-back, Stall, Nittos. I never made it back to try more runs (that was only 1 run) but I'm sure I could have hit 12.7 without much issue in the AZ heat.

I also had a stall in my '02 Turbocharged Denali. I put in a Precision Industries "custom made" stall at 3400rpm. I could go that high because I had all-wheel drive and no worries of burning up the tires.

With as much power as my GT has now, there's no way I'd put in a Stall unless I could do a mini-tub or it was only a track car! :lol:

I already have a TCI 3000 stall converter sitting in the garage waiting to go in.

At launch the converter doesn't completely lock up. Torque multiplication only lasts for a split second at launch. A stock converter has a 1.9 torque multiplication aftermarket ones are around 2.5
