Okay we are haveing problem's hooking I think I know what's up but my buddy think's I'm full of shit so let's see what you think Hutch
560 BB 960 NA power with about 850 torque
leave on fogger ,second stage is a plate about 500 to 600 squirt total
ladder bar mini tub
400 turbo with brake
10.5 tire
3.73 gear
first convertor was 5600 on motor
second convertor was suppose to be 4400 but was 4800
third convertor was suppose to be 3800 but was again 4800
all where 9 inch convertor's and sound's like it's driveing throught it on the line

now am I right that it should be about 3600 to 3800 stall NA
and should it have been a 10 or 10.5 DIA.
60's are very bad 1.40 1.45 blowing the tire's off
should it not be about 1.20 - 1.25

The 9" converters work very well if properly setup. What rpm are you actually launching at?
What steps have you made to try and control the starting line tire spin.
What were the ET's and what slip numbers did the combination produce at the finish line.
Tighter is not always better and yes most nitrous converters end up in the 3800 to 4500 rpm stall range.

Talk to you soon ,Hutch
