I dont have the car running/moving yet but Im going to jump on the banwagon and add a stall to my car while Im at it....what size stall would be good for my mods? Ive heard that even though my mods are not that much a stall would really knock down some tenths off my ET's and still be very driveable on the street...this will be a daily driver in the summer ....and someone told me that since I have put the LT1 cam in I have moved my power band up and putting a stall is needed...so I come to you guys for help..

Ive heard anywhere between 2000 and 2600 would be good..

thanks

 

For you I would go with something around a 2800. The cam will definitely move your power band up and the way the tpi is designed it usually makes peak tq at around 3000 or so rpm. The only real way to know though is to have it put on a dyno.

 

Wassup NC peeeples!

I'm no expert, but on a few different occasions, I've heard people mention that with TPI, it's VERY important to make sure you chose the correct TC stall speed. Sure, you wanna move it up because you've changed your powerband (a TC is good even for stock motors)...but keep in mind that since our (TPI) curve drops off so low, you don't want to lose too much of the low end driving range, only to launch hard and immediately run out of RPM's.

...at least on a daily driver, where you spend plenty of time on the "low" end of the powerband.

....I'm just regurgitating someone elses knowledge, but it makes sense.



*edit*

Did I mention that I don't have an answer....only something else to make your decision more complicated! Bahhhhh!

 

I think it's hard to go wrong with a 2,800 stall converter in these cars, even stock. As long as the converter is quality and has a lockup feature it will be fine as a daily driver. Definately add an auxiliary trans cooler too though.

 

What would a 2800, lockup, what rpm would it be then.

 

The lockup feature has nothing to do with the stall. It just allows the converter to be locked in 4th gear for better gas mileage and reduced heat from converter slipage at engine speeds below the converter's stall.

It's still a 2800 RPM stall converter.

 

sorry i wasnt clear, what im sayin is, that when it locks up does it drop a few hundred rpms like the stock one, or does it drop more than that.

 

Oh, no it's just like stock when the lockup feature engages. It may drop a bit more RPM, because you may have to give the engine more gas to compensate for the converter slippage to maintain the same speed as you could with less throttle and a stock converter. The coupled (locked up) engine speed should be identical.

 

what about this one?

http://cgi.ebay.com/ebaymotors/ws/eB...K%3AMEBWA%3AIT

someone also said to get one from a 95 S10 4.3......says that stalls about 2200...true or not?

they are both about the same price...but the one from ebay sounds pretty good...I thought stalls are a set speed...how come thier range is so wide?

 

For a daily driver/part time racer a 2300 to 2600 stall will be fine.

 

what kind of gains would I see if I got that ebay stall?
would that one be better than the S10 stall? why does it say between 2150 and 2650? I thought stalls had a set stall...can someone explain that to me?
Will the 30 spline fit my trans?

Would I still be able the smoke the tires at will if I wanted to?

When I go to change the stall how hard is it to change? I just drop the trans and pull the old unit out and slip the new unit on? thats it? anything else I need to change or replace?

 

the only way i can explain this is if you have a stall that is rated at say 2500 with a bone stock motor,you add a cam,gear etc. it may stall at 2800,more cubic inches will raise the stall speed for sure(like going to a 350 from a 305,350 to a 400........

 

What sets the actual stall speed is engine torque, and vehicle weight.

 

Exactly. It is impossible to say exactly what the stall will be. A converter may stall at 2,500 with a 305, but then stalls at 3,200 behind a big block. The best thing to do is call a converter manufacturer and tell them about 15 things about the car and they will be able to tell you where a certain converter will stall based on experience.
