What kind of stall do you guy see when you mash the gas behind a STOCK-ish LT1?

Just curious.

Thanks,

I want to know how people know what they are stalling at? Don't you need equipment to tell what it stalls at?

 

I think he is wondering what the stall flashes at behind a stock LT1. I have heard it is around 3k, but I would also like to know.

 

I'd like to know too, cause everyone says they stall higher than they say. I would like to know how they know this. Can you just read the stall speed off the ECM?

 

ok, well when i had a stock motor w/ a 2800 stall. From a dead stop to wot it went to around 3000-3400 b4 it took off

 

No, the stalls flash speed is determined by the what the stall is designed for (ie pump, size, etc) and by your motors power. A more powerful engine will stall differently then a stock motor, it is not simply programmed into the PCM that way.

The only way to know for sure what the stall will flash to is to install it and figure it out, but I am sure someone on here with a Vig2800 can tell us their converter flash is.

 

That is what i am talking about, how do you know where it stalls on a particular motor set-up? don't you need special equipment or can you read it off the ECM? I was not talking about programmin the stall in the ECM.

 

In other words:

How do you " figure it out"?

 

lol, just look at your tach when you launch

 

Nothing in the cars computer is going to have anything to do with the flash. If you buy a converter from P.I. and tell them your setup, they can probably get your flash speed within a few hundred rpm's of what you ask for.

You have to understand that it is purely mechanical.

 

3000-3100 for me. I have all bolt-ons and a cam.

 

Let me word it simplier,

If you have a vigilante 2800 stall converter,

From a stop -OR- slow roll when you mash the gas petal what rpm does the tach shoot up to!?

No special equipment needed just an auto, converter, tach, eyes, and foot.

Thanks for the replies guys. Looks like over 3K. I appreicate your numbers.

I await more responses.

Mine flashes to about 3k. It brake torques to 2k before the tires start spinning. Hope that helps you.

 

a trans brake is the best way to truly optimize the usage of a high stall torque converter.

 

I don't have a trans brake and don't plan on getting one any time soon.
