How does the MAF compensate for the dry shot?
Would spraying it 3-4 inches from the MAF make it any more efficent?
I have mine spraying through the bottom of the air filter.
Spraying mine where it is compared to 3-4 inches away seems like closer would be alot colder going into the motor. Make sense?

I've also run with no jet in the same nozzle and only got 110hp because of other additonal restrictions in the system.
the closer to the intake valve the N2O is introduced, the more responsive the system will be.

Your buddy if hes traction limited to a 1.80 60 ft, why wouldnt you move the nozzle back/extend the line to soften the hit?
Since he was on 18" street radials, I just pulled some timing out from 1200 to 3500 RPM with edit to help it hook.
He's working on getting some good sized drag radials on there, so we'll probably put the hurt back to it.

We have tested a simply dry shot at 25hp and up to 70hp on an s10. Seemed like the a/f always stayed the same all the way up to the 70 hp shot. It was dead flat at 12.9:1 a/f.
My theory is simlilar to most, the cold nitrous cools the wire yes, the wire actually gets real hot. I do not think it max's out to quickly. A tiny 50 shot is not going to max it out, there is just not enough cold air flow. 200 shot is a whole new game. I think that the MAF will make ajustments up to a very high HP shot. It definatly was adjusting the s10 a/f ratio based on shot size, the more nitrous we added the more fuel it added thus keeping the a/f at 12.9:1, it was pretty cool to see that happen.

Sounds right to me.

Ive sprayed directly on the wires for quite a while now. I have always logged this and anywhere from 75-100-125-150-200 Ive always held a 12.8 while spraying. On motor my car is also at 12.8 wot. I dont know what you guys are talking about with this maxing out/freezing the maf.

What does it run?
I think bolton cars would have alot more room then a H/C car as far as maxing out the MAF tables.
Its undergoing heads/cam/intake now, but it was stock with moser 12 bolt w/3.73's, all aftermarket suspension pieces, slp dual/dual, intake lid, and descreened maf. Best time with that combo on 26x10.5x16 et streets was 11.13 at 124 on a 150 shot(?jet drilled out with a 1/16' drill bit). This is a full weight(3840lb) WS6 convertible with 285/40/17 tires on the front. All done at ATCO this past summer.

We're using the innovate LM1
I've never seen one run at 12.8 on stock motor or nitrous

nope, the nozzle itself is a restriction equal to around a .085 pill.
about 200hp shot.

A Nitrous jet size of .082" or 2.0828mm should produce:
303.66 HP with 1 port(s)
Actual HP to the wheels: 258.11 HP
That is at 900 psi bottle pressure.
I run a .062 jet I'd love to try the .082

I personally don't beleive in the whole dyno craze thats going on. If I am going to drive my car mostly on the street it will be tuned on the street, if I use it for track only it will be tuned on the track, etc... I have logged all of this for fear of burning up the motor on spray. The car has had mototron 60# injectors in it for a while now and if the maf was pegged everytime it was sprayed those injectors would more than flood the motor. This is another reason I dont understand the whole freezing thing. Maybe my car is an exception to the rule(i doubt it but you never know). Anyway, I tend never to take someones word for it when it comes to my own property, I like to find out first hand on my own and this is what I found out. Here is where I spray just so you guys know for reference:
