When to add a second meth nozzle?
So I put a smaller pulley on and I'm doing 13.5-14psi on my stock bottom end LS3. Currently I have a single 15gph meth nozzle and my Alky Control controller is set to the max value of 8. I was thinking of adding a second nozzle for the meth. 91 octane pump gas also. What say you all?

There is such thing as too much also. When I added the second nozzle, I had to mix the nozzles up and go in between the single and dual amounts. I forget the sizes now but the single (15 I believe) and the second that Julio sent was a bit too much on my car.

It was loading up at the top and getting super rich, unless I dialed it way back on the adjustment. I like to keep the adjustment around 5 or 6 so I used the nozzles accordingly for that. I could have pulled a lot more fuel out up top, but wasn't comfortable doing it that way.

Now I'm worried about my single nozzle. I know mine is fairly underpowered even with the largest nozzle they have. My only concern is finding a spot to place the 2nd fitting on the charge tube.
If I up it to 700whp with this pulley swap I'm definitely going to throw a dual nozzle kit on somehow.

I know we all love to add stuff and of course then say how great it is, but to be honest, after testing, I think a single 15 nozzle is fine at my power.
It may be different with straight meth. I run 50/50.

Julio sized me with one 15 nozzle for 850rwhp and I've never had a problem
