Nitrous Oxide - Help Me with My NX Jets and A/F (Need Opinions)

OK Have a Dual NX Kit, you guys all know me by now :jest: . I want to get my A/F a bit higher and want your opinions on several options below.

Here is some basic info on my set up:

I am at 11.2 A/F on the Juice on the dyno running 22 deg timing N/A.

11.2 A/F is with the following NX Jets listed below on each side
(obviosuly have total of 4 jets, 2 jets N20/Fuel on each side of my set up):

#35 Nitrous Jet (which is for 100 HP)
#22 Jet (which is for 150 FUEL) so I am running a little FAT on the fuel jet.

OK I was thinking to just change ONE JET one ONE SIDE of my set up. First of all is that OK to do???????????? :lurk: :confused: Mixing jets on each side, or should both jets be the same on each size. Is there any issues with hurting my engine doing this??

I am shooting for maybe 11.5 A/F or there abouts

I was going to either SWAP out my current #22 NX Fuel Jet (150 HP Fuel Jet ) on One side and ADD a #18 Fuel Jet (which is 100 HP Jet) just to ONE SIDE.

OR

I could add the next larger size Nitrous Jet to One side. I currently run a #35 (which is a 100 shot nitrous) on each side. I could up that Nitrous Jet on just one side to the next larger #41 Nitrous Jet?


WHich is Better to achieve a slitgly leaner but safe!!!!!! A/F.


Add #18 Fuel Jet to One side

Add #18 Fuel jet to both sides

Add #41 N2O Jet to One side of my set up

ttt for ya :)

I would say it will depend on the A/F graph. If it is a flat 11.2 across the board then you might be able to sneak up on the 11.5. But if the A/F is leaner in places and just eventually dives to 11.2 then I would leave it alone. If the nozzles are before the throttle body then you should be able to stagger jet them with no problem. If they are after the throttle body I would not want to do it that way for fear of one bank being leaner than the other.

You make a good Point. Here is a picture of my set up. Please look at it. I don't want one side to be Leaner than the other, but I thought if it is spraying a mist on both sides having mismatched fuel jets on each side wouldn't matter, but I am NO SURE????


Well, I just swapped out the FUEL Jet on one side (The Passanger Side) to a #18 FUEL Jet, used to have a #22 Fuel Jet.

So now on the drivers side I am #35 N20 and #22 Fuel and Passanger side I have a #35 N20 and a #18 Fuel.

Again, is this OK?????????????????

It will be fine there. I've tuned several that way.

Thanks and nice 10.64 Champ. LOL I wonder if I will be there?

Ran several 7.15's at almost 95 mph in the 1/8th, 11.42 at 123 mph in the 1/4 (could have done better bad 60') all Motor, but on BFG Drag Radials. Best 60' was 1.58

Now I am on Nitto 555 DR's. Only went to track once, but only got 1.78 so far :eyes:

I have a Big Stall, Yank SS4000 so spraying out of the hole woul dhelp, but on a stock tranny and Nittos not sure if it would hold or i would break some stuff.

Might set it (for the track) at 4300-4,500, then I can brake stall at 2,900-3,000 and as soon as I hit it it will flash a bit past 4,000 and by the time I start to hook, hopefully at 4,500 the 100 shot will take me to victory :jest:

Thanks for the replies I hope your smart and know what your doing :jest: , anyone else :)

Thanks
