Torque Converter Install and Question

[crazypete]

the car it was tested in went to 3100 before the tires would spin i would guess you should have gotten about 3000 with your gear ratio

Wait a second.....3100 rpms before the tires spin?!? Does he mean "begin to turn over"?!? A 3000 stall will start to turn much much much sooner than 3000. I think that is the flash stall speed. The true stall is much lower. If he had to rev it to 3100 before the tires started moving at all, then this is some sick 5800 stall or something converter.

The purpose of a torque converter is to allow the engine to spin up more before engaging the drivetrain. Your rpms are controlled by your shift kit and the tv cable...shift points. A low stall converter will start the car moving at lets say 1200 rpms and a high stall will wait till 2000. This is what the official line is. I, personally, have never seen that advertised behaviour. I'm not sure what the 2000 and 3000 stall number engineeringly implies but it is not the speed at which the car starts moving. My car will move at 600 pms when I take my foot off the brake and it will move at 2000 rpms which is my cruising rpm. This is why I'm like "huh" when the guy said to you it starts spiining tires at 3100.

Actually, since it is no-lockup, maybe you get converter slippage when you gun it now since you are not near the converter's stall speed and this robs you of tirebarking snap that you used to have in 3rd when the direct drive shaft locked up.
