In Reply to: One more....a stall converter. posted by Mavman on May 28, 2000 at 19:03:35:
think of a torque conv as two fans facing each other. one the driving fan, driver by the engine and the other the driven fan the output shaft on your trans. The smaller the fans the more rpms the drive fan has to spin to drive the other fan and move the car. the more weight the driven fan has to move the more it has to be spun. Bigger fans spin easlier and the fluid is the air. Then you have the gear ratio also multpling the output of the driven fan. Light car smaller conv. is easier to use. Heavy car is more touchy. The cam makes the engine idle at a curtaim rpm. If the Fan is to big the car wants to move immediately, smaller one, has to be spun more.
: Can someone pass a little info to the rest of us on how a higher stall converter works/helps? My understanding is that the stall will not give a solid lock up until the rpm range that it is designed for. In other words, say it's in the 2200-2400 range. This would let the motor build upto that range quicker, thus putting the motor more into its HP and torque range before entirely hookin up the rear tires. Would this be a good assumption? So if the stall is stock(~1600 rpm), the motor will bog if the rpm range is say 2000-5500, but once it hits 2000, then of course the motor will open up? But due to the bog, the damage is already done as far as a quicker take off??? Thanks for the help!!! Send me an email. Sorry for the question this close to the end of the month.
