Meth injection question
Preparing to install a A&A V3-Si supercharger (with 10 lbs of boost) using the supplied 60 lb injectors with the kit and upgraded fuel pump. The existing mods to the LS1 are XS-Power 1.75 headers through the XS Power X pipe hi-flo cats and into Ti exhausts. RHS Pro-Action heads with 2.02 int and 1.6 exh valves and 62cc chambers (approx 11:1 compression). TSP 224r cam 224/224, .581/.581 @114 with upgraded springs, lifters and the Comp Trunion upgrade on new rockers but still 1:7. The intake is a ported LS6. This combo produced 398 RWHP/385 RWTQ on the dyno.
My question is in regards to the placement and number of meth nozzles I should plan on. I have an AquaMist HFS 3 kit (converted to use 4 AN braided hose lines from the tank to the nozzle(s)). The tank will be mounted where the battery used to be as I have already moved the battery to the rear of my 2000 coupe (MN6). Assuming a power level of between 550 and 600 RWHP, how many nozzles, where and what size would be adequate and would that recommendation change based on a meth dependent or non-dependent tune?
Thanks for any input.

I am not sure about that kit, but I know with with the alky control kit for that power range you only need one nozzle.
Something else to consider is blowers+ hi flow cats aren't a great mix there are numerous guys on the forums with issues. I personally would recommend getting rid of them.

Back to the meth nozzle question, using the calculator by AquaMist the recommendation is a dual nozzle. I will have to see how their jets line up size wise with the jets M10 and M15 from Alky Control.
I would either contact your tuner and see what he has to say. I only know about the alky control kit.

Update:
Talking with AquaMist they recommend dual nozzles. Keeping in mind their nozzles, as far as their documentation states, are finer and for example their 1.0 nozzle is equal to an M5.3 nozzle. So dual 1.0’s would be approximately equal to one M10 nozzle as used on other systems. (For example the Alky Control system has an M10 or M15 nozzle.)Taking that into consideration, if I run dual nozzles I could place them close together or stagger them. Looking at other vendor meth systems fact sheets (AIS), they mention an advantage to staggering the nozzles. One pre-compressor and one pre-throttle body. Wondering if anyone has experience with this type of staggered placement and can comment.
Thanks for any input.

Just put them in the charge tube. A foot or so back from the throttle body will work fine
I've seen some people with heavily restricted large blowers (f1x) run a nozzle pre blower, but there's really no need on what you're proposing.
I'm running one m15 nozzle so I expect a one m10 equivalent will work just fine for your setup

If you were running a AlkyControl kit a single M15 up to 700rwhp is what I use. Other kits I tried over the years never flowed near as much meth as Julio's setup. So I quit using any other kit and stuck with AlkyControl exclusively. I was typically tuning meth dependent at my old shop.
