School me on torque convertors

the factory low stall converters are more fueleficient and makes alot less heat, most stock engines makes enough torque at low rpm to work well with the lower stall.

first of you may need a looser converter just to be able to idle a big camed engine in gear second you want the converter to flash to about the rpm where engine makes peak torque for maximum acceleration,this may or may not be doable in a streetcar since a 5000rpm stall converter may slip alitle to much in normal driving.

a for example 3500rpm stall converter does not mean thats where your car startsrolling,thats where its suposed to be locked up,it will always slip alitle when drag from the car moving thru air is acounted for.

there is a big diference betwen a good and a cheap converter when you start to make some power a cheap converter may flash to a set rpm but will slip alot above that range and will slip alot during normal driving while a real good converter will feel almost like driving with a stock converter i have a custom made converter that flashes to about 3500rpms and it drives almost like a stock unit except its alitle looser at idle. a friend of mine has a cheap **** converter that stalls about the same and his car hardly moves under 2000rpms and has horrible slip at the top end at the track something like 14%

also a converter that says its a 2600rpm stall unit may stall just that behind a stock 318 try that same converter behind a mean 500+cube engine and it may never lock up.

it depends on alot of factors wish converter to chose for max perfomance you want a stall´speed close to peak torque,if you drive it around on the street and have a nice torquey engine you may apreciate a lower stall unit for efficensy and a all around nicer driving car.

just my two cents and im not an expert i have just learnt that i like well made converters and i dont care if they cost me more:)
