Total Domination (PI) billit converter 2600 stall is what i bought from Factory Tech.


Suavy

 

I believe Hughes sells them for $599, but don't quote me. I got mine for $20...won it in a raffle in Vegas at a PSCA event.

 

I don't think the stall is that important in the Lightnings, compared to the stall torque ratio.

I have been studing converters lately, as mine appears to be wounded. I think a 3000 stall with a lower stall to torque ratio will work. I'd go with a 1.6 or 1.8 STR converter.

Case in point. I raced a guy that had a virtually identical engine setup (2 lb pulley and chip) in his truck. He was .4-.5 seconds quicker than me. His truck launched so hard I couldn't believe the only difference was a Yank 3000 stall converter.

He tried a 3000 stall with the 3.0 STR, and couldn't hook up the truck. Way too much torque multiplication. He had it lowered to a 1,8 I believe, and the thing was awesome.

 

Has anyone else here dealt with Yank converters....sounds interesting.

 

Yanks are all custom made and you can have him set the stall for whatever you want ... Yank or PI are two of the best but very pricey ... here's a link for Yank -

Suavy, how do you like the PI 2600 i was thinkin about gettin the same one. How much better do you think your truck runs w/ it?

 

The way it was 'splained to me, there are several
ways that companies make convertors. The cheapest
ones are the ones that they just re-align or bend the
existing vanes in the stock convertors up to a specially
engineered (Ugh...I hate that word and it's implications!)
version that delivers stall to torque ratio that YOU
specify.

After all, aren't the only benefits gained a higher RPM launch?

Or am I missing something?


Nobody answered aye or neigh on the MIDWEST question either.

But if FT makes one, I'm leaning that way ...

 

Infommercial to follow.............................

We just had some converters made special for us that are billet and have a 2400 stall.

They are 12" and go for $699.00

I will post this as a seperate thread but thought, since someone was asking about converters, that it would not be too offensive to anyone for me to post it.

 

Thanks, Tim ...

What's the STR on them?

 

Your selling yourself short by not contacting Yank - and the answer to the question on Midwest from what I know Midwest is at best marginal -

A tourque converter is not something you want to cheap out on - bottom line - you get what you pay for ...

Don't pass on Yank just cause 'I'm' recommending them - hands down they are a super converter ... You will pay a few $$$ more and you will wait a bit cause he builds everyone to order ...

 

STR is a multiplier of torque to stall speed. I really don't know much about it other than there is only one facility in the country, down in Texas, that can facilitate this test. The OEs are about the only people that can realistically afford to have this test done as it costs about $25,000.00 per part to have it done. The average STR is 1.68 to 2.1 to 1 and the STR decreases as the vehicle speed increases to become 1 to 1.

Certain manufacturers like to throw out these #s, but it is doubtful that they actually had the test done unless they are very large and/or are OE affiliated.

Another multiplier of torque to stall is called the K-factor. This is determined by dividing the square root of the engine torque by the stall speed. The K-factor, I am told, on the Lighting OE converter is approx. 205.

Now, please realize that all of this info was given to me by the company that is doing our converters and if you ask me another question it will probably take me another hour to find out the answer for you.

With all of the variables involved in these equations, stall, torque, vehicle weight, speed, I don't know how anyone who isn't a mathematician could figure it out without using a late model computer with some pretty fancy formulas.

What is THE best torque converter for your truck. I don't have the answer to that because every truck has different mods, power, and torque. I was told that the best stall for our trucks, on the average, is approx. 2400-2500 rpms.

I DO know that the company, whose converters we are selling, has many satisfied customers with this unit, as it is a very high quality item at a fair price.

I now have a headache.

 

Hog,

I would NEVER do that!!! Anymore than anyone would not
buy something just because I recommended it ...

I am just trying to justify the benefits from the part. It seems
that some people just don't think it adds much for the money.

<grin>

I'm sorry. Didn't mean to cause that !!

 

I think you'd be better served spending your money on other HP go faster products, and leave the TC as one of the very last items to bolt on ... I can think of much more to do with $700 - good luck on your project, I really am your Bud you know - ...

I haven't tried it out yet my truck Suavy is set to be completed a week from this Sunday. I will get some tuning done then its off to Super stallions at Cecile, MD on April 12th.

I hope to see you all there.
