So did some headers to my car. Got a little lazy and didn’t bother putting the torque converter cover back on. What i discovered were my temps dropped an average of 10-15 degrees. Hopefully give some bad but useful advice to the drag strip guys. But my question is does anyone make a finned converter cover to allow heat to escape or fresh air to enter?!

I do not use a cover on mine either. However, did consider cutting a hole at each end of one so converter centrifuge could act as an air pump thus improving cooling. First I have to find cover, When I went from 350 to 383 the flex plate was larger so original cover would not fit .
