I'm gonna have the tranny at least partway out, since I have to replace a cracked flexplate. The Turbine Technologies 2500 stall converter is $189.... would it be worth it to do the swap? Do converters with this much stall kill off the line throttle response? I don't want to have to sit there while the engine revs every time I give it a little gas. On the other hand, I should be able to jump right into my powerband as soon as I floor it with this converter. The 2000 stall converter I have now is better in that regard than the stock 1654 stall unut, but it really isn't that much of a difference. One last thing, I have 2.73 gears, would a 2500 stall converter work OK with these gears, or would it have a negative impact on performance? thanx

You know 'MrJ' it's not so much about gearing as it's about your power band, and how much time you spend in that power band.
Generaly most stock HP can't achieve the rated stall. My question is have you ran some stall test to see if you can achieve at or above your current converter.
I know most stall converters are sold as 2000, 2500, etc. but in the real world they should be sold as 1500-2000, 1500-2500, depending on your HP.

Lemme see... I have done tests before, I've powerbraked my car many times while drag racing. I can feel the power start to transmit to the rear wheels at about... I want to say 1800 RPM. I'm guessing that the car has around 225 hp, and the powerband is from 1700 to about 4800 RPM.

 

Just do it! :-) Since you'll already have the tranny out of the car, or at least good access to the converter, the labor is free. That's a really good price for a 2500-stall converter! It's working well for Dan Burk and that's not too high of a stall that it'll make the car less driveable on the street. You'll definitely get better 60-foot times if you still have traction, and the converter will work fine with your gears. I have a 2400-stall converter from Precision Industries that worked great with my (former) 2.73 gears, and even better with the 3.42's I have in the rear now.
