11.65@116 w/ M15 nozzle. Should I go with a dual nozzle?

It's my kit. DIY kit. No controller.

PT52 turbo
93 octane w/ alky
26 lbs boost.
THDP
9x11 3600
Eric's chip 23/19
60lbs inj
1.60 60ft (bone stock suspension) 104k miles
Powerstoke Intercooler

Stock motor. Never opened.

No knock. O2's in the 770's but that is a narrowband.
 
IMO you don't need a dual nozzle. I have gone 117 with a single and I plan to go 120 on a single.

Look at the post in this same section by 'spins4', dated Sep 14, with 'dual nozzles' as the topic.
 
Works like this. You see knock, add alcohol. By whatever means.

Dont see knock.. dont add.

What nozzle and sizes works for one person doesnt work for someone else. All engines behave differently.. is what it is.
 
dual nozzle

my bufford went 11.7@119 on 93 with alky control & on a single nozzle. Still had 5 more posistions to adjust up on how aggressive the pump would get via boost level. It was at 22 psi with zero knock. I have never liked re inventing wheels so I stick with simple proven methods. In december when my car traps 125 plus I will re evaluate the tune. Then might add the second nozzle.
