I'm interested in the kit, but confused about something. I'm supercharged with the MP62 blower (not a turbo, I know but bear with for a sec) and keep hearing that I could spray pre or post blower. It seems to me that if you want to cool your intake charge, you would do it after the blower has added the heat, not before. Spraying pre-blower doesn't seem intuitively correct.
Help me out here so that if I buy it, I don't plumb it up stupid and end up not achieving the best of what the kit is capable of.

For the M45 I think the 3GPH would work fine. Or if you wanted to give something a shot that I think may work well in your situation......You can go dual nozzle and lower the pump pressure slightly. Do one 2 gph precharger and one post intercooler. I'd love to see the effects and get some data. You could run that and then try just one nozzle or the other. If you found one nozzle more to your liking I would gladly buy back the $20 dual nozzle upgrade
I used the nozzle calculator and got 1.65 gph based on a 1.6 with 10psi, and 7200rpm.

Ok I just brought up the concerns with Chance at Devils Own. His concern with spraying before is if you spray waay to much then the mist gets turned into droplets. He also said that on smaller engines the calc should be taken as a reccomendation...not the rule. I sprayed before the blower on my TRD(MP62) Supercharged Tacoma. 7 psi 3.4 liter. I used a 5 gph and then tried dialing back to a 3 gph. The calculator says I should be using a 3.5 gph. The truck whooped way more *** with the 5. More pull everywhere. When I had my blower apart I never saw any indication that i was hurting anything at all. As a matter of fact...Chance said that on his own car he is spraying pre blower.

So yourself and chance inject pre blower - but recomend i inject pre and post intercooler?- with 1 injector - size of 2gph before s/c and 1 injector -size 1gph post I/C?
and adjust the pressure of the pump to suit?

I am throwing the dual nozzle out there as an idea. If you don't want to test it thats ok with me too. There is no exact science to this. The nice thing is that jets are cheap...i'd even swap jets with you guys straight up if you want to experiment with other sizes. If you want to play it safe and start out with as little water as possible, get the 2 GPH and mount it right after the intercooler. You are going to reap benefits no matter where you place the jet...short of the exhaust
With the knock monitor you have listed in your sig, you should be able to tell when you are achieving your own goal which I am assuming is more boost on pump gas with no knock.

The exhaust part or the anywhere part?
Ok...I wouldn't spray pre compressor on a turbocharged setup. I guess that can make short work of a compressor wheel.
I also wouldn't spray though a maf.

do they have a selonoid so i can do staged injection? how much would that run me i am wondering if it would come otu cheaper than peiceing the rest together. Also they got anything smaller like a 1gallon jet. do they run on 1/4 inch line?

I could probably do a solenoid for around $30 bucks. They do use 1/4" line. I will ask about a really small nozzle but check this link out.....pretty interesting and may have just what you want. http://services.bete.com/scripts/wsi...r?capplic=99.9

if you can find it for 200 or so i would pay you i was looking at that much just to buy a cheapo kit for the nozzle and a seloniod. yes i use 1/4 inch od line not sur eif it is different from the DO stuff. with this i shoudl be able to pull 15 psi hopefully

a selonoid/nozzle combo i can get line at any ace or homedepot, lowes something that keeps the second sprayer from comming on even with the positive pump pressure already on the other nozzle.

the sa looks about like it would work but i cant see how to change it to compresion fittings on 1/4 line. i am kinda lost looking at all those nozzles. i might just get the selonoid from mcaster and a new nozzle assembly from snow as the compatibilitys of varius components is very vague.

What would this do for my setup?
Engine:
'99 1.8L Bored for 9:1 compression
Wiseco Pistons / Pauter Rods / New OEM Crank
Voodoo ECU Piggyback from FM
Greddy Manifold
T-25 Hybrid (Saab, Pontiac, 300zx donors)
Spearco Intercooler
Tial 35mm Wastegate (7psi)
Tial BOV 12lb spring
Custom IC piping Blue Powdercoated & Valve Cover
If I did it I'd do the $200 setup and I suppose spray just before my throttlebody with a 3gph nozzle??? With just my Voodoo box controlling my fuel and timing would this be ok? Would this make it possible for me to increase boost with stock injectors, pump, and no fuel regulator. I just bought this car and don't know everything about it. I do know that i plan on installing a BEGI fuel regulator and a 190HP.
But you know what i'm also new as it gets to Miata's besides all the stuff i read and have experienced working on my roommates. If I need a good b*#ch slapping, straighten me out. If you think I would have some good gains i think i can come up with the cash.

you will need more fuel regardless but this will allow you to make more power with the the same or a little more boost do to the cooling and slight auxilary fueling of the spray. you have a returnless fuel system so a rrfpr would require a totally revised fuel system your best bet would be to get something to run bigger injectors and use this to keep your effeciency up and everything safe. how far are you trying to go? 300whp 500whp tell us that and we can show you what you need.

Jesus will my internals (wiseco pistons 9:1, pauter rods, new OEM crank) withstand 300 WHP? I would like to stick to pump gas so I can daily drive this beast. I'm only running 7psi right now and it's amazing but if I can safely run 10-12 which would bring me to around how many HP... 270 maybe? I don't need a 300whp beast but if it would be possible with just fuel upgrades and WI i'm game. Even if it takes me a year and a half to budget the upgrades in. So let's say i'm shooting for 270 whp what needs to happen. I had no idea I have a returnless system. Man I need a factory manual or something. That's what I get for just jumping into a new car like I have. There is SOOOOO much info, i'm near an overload.
