what i mean is.....if i barely give my car gas will it still wait until 2300 rpms until i starts to move........or will it drive like normal when i dont floor it?

also........is it any different to launch with a higher stall than with a stock one?

and lastly should i see some E.T. gains from this on my stock motor?(soon to b changed to a 350)

thanks

 

You'll start to move as soon as you give it any gas. The difference is that in a higher stall converter, it needs to slip more at lower rpms. This slipping creates heat so an aftermarket cooler is highly recommended for any converter swap.

My converter stalls at 5700 rpm on the transbrake. The car idles at around 1000 rpm. As soon as I touch the gas, the car will start to move. The only real difference I can see is that I can hold the car with the vehicle's brakes to around 3500 rpm or so.

At engine speeds below the converter's stall, the converter needs to slip, Since full engine power isn't being transfered through the converter and the rpms will want to climb higher, reduced gas mileage will occur.

A higher stall converter allows the engine to rev up and get into it's powerband quicker. After reaching the stall speed, all converters are in 1:1 and operate the same.

 

So with a 2400 stall or around there I wouldnt be able to push the brakes and rev the car up to 2400? I would only be able to get to about 2000 or so you think?

 

I think the car will try to move BUT wont break the tires loose until around 2400rpm. Something like that anyways. This will allow you to launch harder. Well in my case I dont think it would hely anything.

My traction is terrible anyways.

 

The only way to hold the vehicle to the converters true stall speed is with a transbrake. A high stall converter can easily overpower a vehicles brakes when trying to hold the car.

The stall speed given to a converter is only an estimate. A converter will stall differently depending on how much torque is put into it. A 3000 stall converter may stall at 2500 in your car but the same converter in mine may stall at 3500 since my engine produces a lot more torque.

It's hard to know exactly what works best in your car since every car is different. Even the weight of the vehicle will affect the stall speed since it's torque that's required to get the car moving. A converter that works good in one person's car may not be the best for yours. You can only guess on what works best.

Anything better than stock is an improvement once any kind of engine modifications are done.

 

When I made the switch from stock to a 10 inch 2500 stall, normal take offs were kinda mushy along with the shifts. Durring hard driving though, the car launches good and the shifts are very firm. I'm able to hold the brake and bring the RPMs up to 2400 before the car wants to move.
