Default How to tell if N2O is blowing through pt4400?

Everyone says this stall is too loose for nitrous but in my case im not to sure. It seems pretty tight, can only power brake it to around 2800rpm and the best 60 on motor is only a 1.68

Yeserday I ran on motor with nitrous tune:
1.68
12.56@107

Nitrous 125 hit:

1.62
11.37@120

The nitrous 60 wasnt dead hooked but the motor 60 was dead hooked. I was thinking a ss4000 might 60 harder and mph a little better on the bottle, what is your guys opinions?

It worked pretty well but I do think this converter might be a little tighter than a typical pt4400.

Yes Sam those are some impressive results.
Remember that your convertor is a torque multiplier
and that you are still running stock internals. That may
be the reason you can only PB it at 2800 and seams
tight to you. If that PT4400 was in your 99 T/A you
would had 1.50 or better 60's.
If you want to stay stock internally and want better 60's
then consider a gear swap.
My PT4000 in Sept. got a 1.50
and 1.48 launching at 1700 on the foot brake.
Just thought I'd give you my .02
