I have one and as said before, nothing special. The advertized stall is 3000, but rarely gets there. Makes the car feel sluggish until about 4000 rpm. I've been in cars with 9 and 10" converters and are waaaay more responsive on the get up and go. I'm going to go with a Pats 9" 3400 I think.
I ran 12.1's all day long at 108 mph with that converter, couldn't get any more trap speed out of it.
