Which jets for zex and where??

somersdp said:

I run in the morning at a big event and need some help. Where can I get a radiator catch can in a pinch? And which jets do I use for a Zex dry kit to shoot 100shot? I know there is one in the nozzle, but is there one by the box somewhere and which one do I use? Thanks for any help guys.......

75HP= #40 N20 jet/#43 fuel jet with 0 retard (10 degrees)
100HP= #46 N20 jet/ #40 fuel jet with -2 degrees retard
125HP= #52 N20 jet/#38 Fuel Jet with a -4 degree retard
(Higher Octane fuel (94+) and you can raise the timing 1-2*)

Use 1-2 step colder plugs and make sure their gapped at approx .35, OR if you have a CD box (such as MSD) you can open the gap to .40-.45

N20 jet goes into the nozzle thats tapped into the intake pipe.
Fuel jet goes into the NMU box
