Would anyone care to share the parts, requirements/tuning,and limitation of a dry 30,40, or 50, shot setup. A few guys on this forum are using dynotune set-up through ram air tubes; what are the pros and cons to that system. I have notice the few 14s that run nitrous at my local track eventual stop showing up after 5 months or so. I live within a reasonable distance of Coby Adams shop and was considering letting him tune my nitrous set. But the 4k price tag that I have heard form a couple of his customers gave me pause. And now to hear that Silver08's set-up is giving him problems I don't know what to do.
What is a simple set-up that will not fry our motors?

I'm wondering if for just a 30-40 shot if fogging the ram air is the best way to go? I bet that the mixture is well atomized at that size shot, without using a spraybar.
I have an Adams spraybar to install, but I suspect that for a small shot it might be overkill...

I havent checked the duty cycle, and i dont have a wideband, (but one is coming soon). I know these factors are critical, but i though since i paid good money to what i thought was the best zx14 tuner around, I wasnt worried about my simple setup.
it is 4, 18jets in an adams spraybar, not pulling any timing (they said it was safe for this size shot), on Q16.
i have an ignition module on the way, and i plan to take it back soon and have it tuned while i watch. And i would like a good explanation why they didnt bother to put colder plugs in it while they had the motor out changing valve springs. My bill was close to 4K for the parts and labor i bought at the same time. I had other problems not discussed also, but if they dont at least reply to me, I'll probably get banned from a couple sites after posting my whole experience.
Nobody is going to ban you here, we all learn from it, and all aspects of your experience, technical or otherwise...

In short , safety , longevity, reliability and peace of mind is not overkill IMO and I would use the bar if you have it.
The b iggest mistakes made is tuning the system, ie timing, plug design, AFR, and if you have access, definately EGT's on each cylinder.... thats will give 4x's the info a a single afr meter will...Will allow you to balance the heat / power across the crank, and prevent piston or valve burning
I had a Muzzy 50 shot, a 32 Jet using their manifold with 2 outlets.... I only used the dynotune bottles.
#4 plug showed the very beginning of problems... a few very miniscule specks of aluminum on the plug ceramic, it also was very light tan color wheras the others were quite dark,
The Muzzy nitrous delivery is at the back of the box, rather than the inlet, and I believe it is deficient in design, the potential for nitrous imbalance grows linearly with the size of the shot IMO.
The best design would be individual jets for each velocity stack, ie adams... MPS spyder
GSXR1300 etc..
The second best design would be the dyno tune, but limited to the ammount ..
I think a small shot up to 30 placed in both ram air tubes will allow enough time to mix, but thats just a guess.
I know smokin has ran a 20 shot in this manner forever, but a guy your size would want 40 HP to give similar results from NOS
Personally I would go with a manifold like adams, or the MPS spyder kit where you KNOW each cylinder is getting equal ammounts.
Uneven firing or nitrous feed creates potential harmonic ( crank) issues on top of lean / rich conditions accross the block.
Nitrous is already hard on bearings as it is compared to turbo's.
The compression stroke pressures do not increase substantially wheras the power stroke pressures do...
So, if someone would like to educate me on the progressive systems that would be great.
I am thinking nitrous will be my poor mans intercooler, especially since I will need compressed gas on board to control the AMS1000, and for the air shifter.
Likely will be just a little 20 shot to cool the intake charge... 20 HP = about 40 HP on a turbo they tell me... plus it increases octane! LOL

I do have an Adams spraybar and a TC-4 for 4 cylinder EGT. I 'm also planning to use a two dial progressive controller. With those you just start at x% and ramp to 100% over x amount of time. Pulsing the solenoid and making things easier on the engine and for traction.

i have an adam's bar also, but i won't install it until I change my springs. currently I have a 28 jet in the left rubber tube facing forward right before the frame.

I am taking it back and having it tuned again sometime in the next month. Dont know if they are going to charge me or not. I am also going to at least use the DJ LCD and WB1 setup to log my runs and make sure things are okay A/F wise.
I dont think the adams bar, or spyder, etc would be overkill at all, they do more to ensure even distribution. Adams did mention today that they have started using stainless lines with their dry spraybar, because the plastic lines (like i have) sometimes crack from temperature changes.
I wish i were closer to Bill Eason (14 cannons). he would be my builder/tuner. I still want one of his setups when funds permit. I am taking it back to Adams, because they tuned it in the first place.
