Hi HT, have been searching and reading about both subjects and cannot get past two question.

n2o (100 shot) is not getting to all cylinders equally. Cylinder 4 is getting 75-90% of all the n2o.
Have tried moving the nozzle 1 inch from the Throttle Body butterfly to 2 feet from the TB. Still same results. 1 inch - 6 inch - 12 inch - 2 feet
Didnt want to direct port ech runner with a 25 shot, do I have any other options?

installing a Catch can still has me stumped as to which set-up is best for my application.
2.2 ej 100 shot
If im not mistaked I want a closed type catch, correct?
Have a Vibrant can, one fitting on top, two at the base.
I still need to put steel wool in it, however, how to set it up?
I dont want to recycle any of that crap through the engine, yet I still need a vac source?
exhaust maybe? Should the vac source be at the bottom of the can and the inlets on top of the can?
I see many pics from searching, most are set up different.

Any help on either subject would be awesome, TIA
