I dont know what Pat Musi is doing except for blowing the scoop of his car at orlando.
And im pretty sure IHRA put weight on the nitrous cars. But we were already heavy by like 25 lbs so it doesnt really matter. We are coming out with some new stuff this year. Our promods will still have the Otzal and 2 foggers, but our Pro Street car which easily won Las Vegas and Orlando with have 4 dry kits and fuel injection.

I remember reading about why pure nitrous wasn't used as the primary source of power due to the astronomical amount of nitrous it would actually take just to keep the engine running... I'll try to see if I can find it.
-Edit- Found it, off of HowStuffWorks.com
The only problem with nitrous oxide is that it is fairly bulky, and the engine needs a lot of it. Like any gas, it takes up a fair amount of space even when compressed into a liquid. A 5-liter engine running at 4,000 rotations per minute (rpm) consumes about 10,000 liters of air every minute (compared to about 0.2 liters of gasoline), so it would take a tremendous amount of nitrous oxide to run a car continuously. Therefore, a car normally carries only a few minutes of nitrous oxide, and the driver uses it very selectively by pushing a button.
Even for a few passes, trying to get the engine started, and idling before the pass would prove a real challenge.
Also, trying to compensate fuel with the decreasing bottle pressure since you're shooting continuously. It'd be a fair amount of microprocessing I'd think.
With that said, I'm sure it'll be further inverstigated down the line.

for something new how about a solenoid with multiple orifices
or an adjustable orifice that would be controlled via PC so instead of rejetting or
controlling multiple solenoids or pulsing it would be all in one!

I'd like to see a dry shot after the MAF controlled by the stock PCM as the N20 engages...I'd like to see a retard added with it and a shut off if AF got too high....THAT WOULD BE THE CATS MEOW

On the p/m cars, are you guys running the 2 foggers dry or wet, with the Otzal being wet?
Congrats on the p/m finishes and with the p/s win in Vegas. Didn't look like there was much of a challenge there in Vegas for you guys. So does that mean you guys are going to show up at more races with the p/s car, or just stick to p/m and do the orlando and vegas races with the solid blue car?

I would need to see the flow data on those in the upper area, but I understand the function of them and seems pretty cool.. You can just T off the nitrous line regulate it down and there is your air source..

How about controlling nitrous flow with a MASS FLOW CONTROLLER? 
It measures nitrous temp, pressure, and density then controls the flow no matter what each variable is at the time. Mass flow controllers are certainly not cheap and the ones we use in industrial applications are kinda large, but every piece of technology starts out a little large right?

Man not sure what a flow nitrous sensor would cost the fuel one we use was almost 2k and thats low pressure compared to nitrous.. I could see a progressive unit adjust fuel curve to nitrous flow curve. HMMMMMMMMMMMm gear are turning, gosh got a headache..

2 Foggers are wet and the Oztal is wet.
But next year the p/s car will be 4 dry and fuel injection, the p/m will have the same setup as this year with the new lines and distribution block we came out with.
I think they re gonna run as many as possible with the p/s car as long as it doesnt interfere with IHRA.
Yea we kinda ran away with it in Vegas. The 3rd system was never even turned on until the final. We have the record but he thought he could break it then so he turned it on in the final but it shook so he had to get out of it but we still won.

I just saw those pressure relief panels you guys have started doing. Damn good idea.
I have been meaning to ask you guys a question. I noticed on Shannon's car there is no return on the regulator on the first kit? Is this because he booms the engine with this kit? If so, can I assume you're using the Otzal kit to do this as it would help cool the manifold just before the run? Or maybe I'm in left field.

Im not exactly sure what your asking. The otzal is the first kit, but it uses each side of the regulator to feed it, the 2nd and the 3rd dont have returns either. But we never test fire our n20 systems.

That just comes down to money. How often do you want to replace fouled 02 sensors. LOL. I can see that getting expensive fast, but if you're already racing, what's another couple hundred bucks a weekend...

We have a wide band 02 in each tube of mikes car but not shannon's, they also have egt's in each tube but they dont tune off any of that.
The only other fittings on the regulators go to the race pack.
