i got the cold fusion nozzle today.

 

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???

 

What size shot are you doing, a 200rwhp. that'll help determine how rich/lean you should shot for.

.062/.033 jetting. this is supposed to be 150 rwhp. the 12:1 a/f ratio is what i was at when i tested the nx and ny-trex nozzles.

 

11.8-12.0 you are fine just try to get close.

got the FJO dual stage controller from 860 performance today.

 

here's the list of nozzles so far that will be tested:

cold fusion
dynotune
hsw black mamba
nx shark
nx sho
nx vortech
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)

 

how old is the shark nozzle that you are using?? I have an older one If you want to test new against old, or maybe there have been no running changes to that nozzle.

 

january old. i already have 7 nozzles to test. 3 from NX. thanks for the offer. waiting on dave@TNT to send me one to round out the testing.

They have some of the nicest kits available... Some of the fastest cars in racing are running their stuff.. Check it out..

 

mrr23-You should see the NX parts by the middle of next week.

95ttoplt1- The Shark nozzle has not has any changes made to it. Still using the original design and still working great.

 

looking forward to getting the parts.

 

don't see where i can buy just a nozzle from them.

 

got the dynotune nozzle today.

 

wired the FJO dual stage controller in. works good. easy to set up. thanks to 860 performance for supplying it for the testing.
