Nitrous 55-65 shot parts requirements?
I usually hang around the N/A sub-forum but I'm thinking of dipping my toe into the dark side with a small shot of nitrous. Thinking of running a Zex dry kit with a 50-65 shot, what will I need to change in my setup? Any advice? Also considering converting to E85 for safety, but I'd prefer not to at the moment if I'd be fine running a 50 shot on 93 pump gas.

Re: Nitrous 55-65 shot parts requirements?
Thanks for the help! Unfortunately, the kit got sold out from under me. Full Zex dry kit, used 3-4 times, with a 3/4 full bottle for $225. Looked like a steal to me, SMH I'm going to keep looking.

Re: Nitrous 55-65 shot parts requirements?
No problem man. and damn, that is a good deal. I paid over 750 for my zex kit, gauge, and first fill. Also, i see youre in raleigh, can you speak on JMills tuning? Im thinking of having my next car tuned there.

Re: Nitrous 55-65 shot parts requirements?
Just like every other tuner I've asked about around here, there's good and bad. It's all anecdotal evidence though, I'd say you're probably in pretty good hands. I had my build tuned by Hung at Phantasm in Raleigh, no complaints here. From what I've learned, Hung tends to tune on the safe side; which considering this was my first engine I've ever assembled (that ran lol) I was happy about that. Everyone here has "their tuner" and everyone else "sucks", so I've learned you usually just have to take the chance. But I've seen good numbers out of his tunes. The only real issue I've head with him is that he doesn't tend to tune conservatively, which may or may not be a problem for you.

Re: ***The Official Nitrous Thread***
Yeah I was pretty bummed. I had confirmed the purchase with the guy and was waiting on him to let me know when he was home when he called and told me that another person who had previously said he wanted it was on his way up from Fayetteville (about a 2 hour drive) and was willing to pay the full asking price of $275. I'd have taken that deal too if I were him, but it sure bummed me out, lol.

Its the same distance as Raleigh from me, so definitely. Did you have a car tuned there? Ive watched some of his tuning sessions on youtube. Seems legit.

Re: ***The Official Nitrous Thread***
Old timer coming back into the game here, I just finally finish my build and wanted your input on my set up. I plan to be on Gas (91 is the highest here in Colorado) but I am already tuned on for N/A but will get another tune on the nitrous later. My motor made 180hp but the dyno Tq reading was not reading. my question I am trying to ask is will I be safe on a 100 shot (.24 pill) DP into my motor with out starting off with a lower jet?? my kit DP is located under the manifold so I don't want to hassle with changing the pills. here are my specs
Block:
B18c1 (GSR block)
Manley rods
CP piston 10.6.1
ACL bearing
CCS Block guard

Re: ***The Official Nitrous Thread***
Wet or dry? The short answer is yes - you don't look like you're gonna run out of fuel. Just remember colder plugs. I wouldn't go back to that dyno though until they can account for tq -- -you need to know where you're making peak tq to figure out how to get down the track the fastest and to determine where you gonna setup the 2-step.

Re: ***The Official Nitrous Thread***
Man I've run 125 on stock GSR blocks. You're all set. The only thing you'll be testing on a kit that small is if your builder/machine shop know what their doing and if the tuner can tune nitrous. Make sure you keep consistent heat in the bottle and you should be good.

re: All Motor B20VTEC w/ Nitrous Build Thread Questions & Suggestions
Flare the exhaust out to 3" if you can: https://vibrantperformance.com/catal...oducts_id=1078
You'll probably be right around 300WHP.

Re: ***The Official Nitrous Thread***
Ok so I'm back again. Setup hasn't changed, but my goals have.
Here's the pertinent info, or you can scroll up, I'm the first post on this page, at least on my browser.
B18b1 block
81.50 NPR USDM ITR cast pistons (11.5:1 approx)
B16 head stock casting
Crower 402 cams
ITR dual valvesprings
Made 200whp revving to 8k.
I'm going with a WON pulsoid to showerhead dist. block to 4 WON Venom nozzles DP dry.
Things I'm changing in my setup:
ID1000 injectors
Aeromotive 340lph pump
Hondata s300v3
Converting to e85
So instead of shooting for 50-65 shot on gas, I'm shooting for 100-150 shot direct port dry on e85 with Hondata. Anyone have suggestions? I've read through this entire thread from page 1, seems a lot of people were/are throwing on big shots (100+) on stock engines. Mine isn't stock, I just don't know if I'm setting too lofty of a goal for cast aftermarket pistons. I'm hoping converting to e85 will negate a lot of the potential for damage inherent in going for a larger shot.
I really want to make 300+whp and hurt some feelings.

Re: ***The Official Nitrous Thread***
No one jumped in with an answer yet, but I had another thought occur to me: when doing direct port dry, should the nitrous flow be aimed directly at the intake valve or just near it? My thinking is that the valves are going to be pretty damn hot, then you're going to supercool them with nitrous...that temperature shock can't be good for them, right? Suppose I aimed the nitrous spray at the top of the intake port, maybe an inch or two from the valve. Nitrous would essentially "bounce" from the top of the port directly into the cylinder without DIRECTLY hitting the valve. Any gurus have an opinion on this?

Re: ***The Official Nitrous Thread***
Yeah it's possible I'm just splitting hairs here, but I like the idea of getting the absolute best, most efficient power out of things. I haven't seen very much info on optimal nozzle placement. If I Google nozzle placement, it's just a bunch of threads about how far away from the throttle body a fogger should be, but I've seen videos where the plume hits and frost immediately forms. I just don't see that being good for the valve to go from 400 degree or whatever it is, to half of it 400 degrees and the other half freezing. I guess it can't be much of a issue since thousands of people have done it, lol.

Re: ***The Official Nitrous Thread***
150 shot is going to be pushing it. It'll last awhile as long as the air/fuel and timing are correct.
Don't worry about the valves. People usually burn them up if anything.
Just put each nozzle in the middle of the intake runner and call it good.
Start with a 50-75 shot and work your way up. Retard the timing at least 2 degrees for every 50hp to start, then you can work it back in if the plugs look ok.
By the way, take everything people say about nitrous on here with a grain of salt.

Hate to bump this thread again since I still haven't done the nitrous yet. Might happen this summer when I get time off from school and can earn a little money. But my question is:
What's the pros and cons of nitrous discharge tubes vs nitrous nozzles? For the sake of simplicity, let's say this is related only to direct port dry applications.
