My chip is flashed for a slight increase in line pressure and torque reduction off do I need to get a reburn if I add a PI torque converter with a stall of 2400?

Would I be better off getting a 2400 stall or a 2600 stall converter for daily driver?

Thanks for your help.

 

If you ask Greg Evans, I think he will teel you to keep the stock converter for a daily driver.

 

Don't get me wrong I just don't want something I can't have on the street without causing any major problems with driveablity.

I am getting the PI just want to know what people have and their experances with there stall on the street.

 

The PI convereter has good street manners. You should not have any issues on the street with it.

 

i have the pi in my truck, i had the tranny rebuilt, and shortly after the convertor made noise so i went to a pi, and i drive it daily and in the winter, it has never given me problems, and very tame, i really cant even tell its there..

I'd definately recommend one! I like it better than what came stock. It makes for a pleasant drive... til you drop the hammer.

My 2500 stall converter is just fine for the street. It just gives that added launch ability when needed. + accidently burning the tires all of the time!

 

Thanks everyone for your insights.

Back to my first question.... do I need my chip reburn for the converter or not?

Still can't decide on which one the 2400 stall or 2600 stall.. I guess I will just flip a coin or something...

 

You don't need a reburn, but one might help, the stall is not a constant number, it;s more accurately expressed as a range, I suggest 2400-2600 which is prolly what you're looking at. The most accurate way to describe a converter is using K factor, but you just about need a degree in fluid mechanics to understand it. The 2400 is more than likely a 140 K factor impeller, the 2600 is prolly a 155K, for my 24-26 converter we use a 155K 11 1/4 diameter impeller with a 12 inch coverplate. The stock K factor is 110K, a GEN 1 stock is 135K and a Navi Converter is 140K to give you an idea of where you're at. Decreasing the diameter of the impeller and turbine lets me get the higher K factor and stall speed without losing the effeciency you normally do with a higher stall converter, by doing it that way I can leave the reactor completely closed and that helps make it a little more streetable, but with anything under 2800 stall you don't have much problem with that.
That said, I don't think you're spending the money very well for a street truck, the advantages you get from a stall converter aren't really that much on street tires. I sell them, and recently I've really had a lot of fun and interest in designing/building them, but I wouldn't recommend them to most people.
