Blow through the converter?
What converter is it? The NA 60ft seems a little slow.

Edge is the cheapest converter I would recommend, I am happy with them. I have never run nitrous.
Give it an Edge, Yank, Vig, Circle D

The rex max is your issue. Your blowing thru the convertor. Pick you up a good stall. You be susprise on how much you with pick up.

what about ptc?

Don't know.

I do know I would be hesitant to install a free revmaxx.

Ptc is a great converter... I love my fti snowman converter set up for nitrous

Another vote here for PTC. I have two friends running them on nitrous and FI setups, and they are some of the quicker cars in their classes.
The nitrous car runs very good NA 60's with the PTC converter as well.

revmax converters are fine even for nitrous.... they do have billet pieces as well though.

From the video it looks like the weight is shifting rearward then back forward, causing it to unload. you do spin after it unloads. not only is it shifting front to back but also side to side. Maybe an airbag in the right side coil. What rpms are you launching at and what rpm do you have your window switch set to spray?

what was your mph on each pass?

Besides needing some suspension work, i know a better stall will help, maybe gearing? I know just messing with my timing knocked my sixty foot down .02

I really dont think you are blowing through your converter based on the mph. I think you are spinning when your car comes back down after the launch. You can hear it in the video. Car hops up on the hit, and falls back down real quick. As it is falling, you can hear it unloading.

Wheelie= wasted foward momentum. If you didnt wheelie youd have a faster 60'

No. Letting the front of the car rise actually softens (distributes over a longer time period) the hit on the tires. As the front comes back down it acts as a lever on the axle/tires. It's not wasted; you get it back.
It's an old argument. You don't have to believe me; take it up with one of the Stock Eliminator or Super Stock guys. They know a whole lot more about this than you and I do

I just now watched the video. It looks like a shock problem to me.
nitrous2 is right; it's unloading and spinning after the initial hit.
I wouldn't change converters or do anything else until you get the suspension under control.
What do you have for shocks? front and rear

Dirty_Bird

So riding the pinion gear and going up is just the same as not and going straight out???? So then is it better to dead hook at the track or spin a lil

Unless you're running stock converter and gearing, it's always better to dead hook.
I have no idea what you're talking about with "riding the pinion gear"... ??

I agree. Looks like the front end just slams back down after the hit.
