Lets talk PT4200 and nitrous Considering a small shot of nitrous later on with the car. Won't go over 150 shot. Who here has sprayed with this converter? Track times and thoughts?
I believe you won't see much from spraying that NA converter. It'll slip all over the place and not lock up when it's supposed to as say a SS4000 or a PYE3600 would. Minimal gains will be achieved.

On a 4L60e you would blow right though that converter and not gain much. Drop down to a PYE3600 and call it a day. I will be selling mine soon if you are interested. Less than 3K miles. I am going Th400

You'll go faster, but not like if you had a tighter converter. If you normally spin that GX cam to 6800, the nitrous will be ok since you have more room for the converter to stretch.
