nozzle shootout
time to cliff note the comparison parameters and finalize it.
ENGINE TEMP = 185*
Runs were in 3rd gear 65 mph
Torque converter unlocked
Wideband O2 in passenger front O2 location before cat
Bottle pressure 1000 psi
window switch set to 3300-6000 rpms
weigh bottle before and after each run
refill bottle after 3 lbs used ( to eleviate pressure drop from being too low)
using the .062/.033 NX jets (150 rwhp)
car for testing:
2000 pontiac formula
auto
3.73 gears
yank 3400 converter
SLP airlid
k/n filter
bassani tru-dual exhaust
tires - 26 x 10.50 - 15 mickey thompson ET Streets on factory 16 x 8 wheels. tire pressure 24 psi.
will use stock tune
at least two runs on each nozzle.
this is for each nozzle
run #1 swap nozzle only using the .062/.033 NX jets (150 rwhp).
runs #2+ make each nozzle the same a/f ratio if different
now, we need to discuss what the ideal a/f ratio to go by. i say 12:1. anyone disagree???

here's the list of nozzles so far that will be tested:
cold fusion
dynotune
hsw black mamba
nx shark
nx sho

ny-trex
will be using the ny-trex .125 orifice n2o noid with ny-trex fuel noid.
four bottles that will have the standard 45* nx bottle valve with 2 piece bottle nut. (big thanks to nx on this one)
