Looking for some advice... right now I have an 03 z running a v3 sci vortech, on a built bottom end (rods pistons, etc.) Heads are stock. 340lph fuel pump, cjm stg 2 FRS, plus a bunch of other stuff, and I also have a snow methanol kit being run.

Is it possible/ok/safe to run a 75-100 shot of nitrous in addition to everything else? Yes I know safe and ok aren't words generally used with any of these applications.

My tuner said it could be done, just throw in the nos kit, put in 370z spark plugs (gap them) and then tune... probably pull 1-2 degrees of timing, and all should be good. We make right now 503whp and 435tq on 13psi.

Thoughts, advice, input?

Get rid of the Meth, run a 35 HP dry shot all the time. Just add fuel in the tune. On FI applications, nitrous functions both as an oxidizer and as a cooler. On FI applications, nitrous usually adds more HP to the wheels than what the "shot" is advertised as. A 35 HP dry shot will probably add 50whp.

Personally I would so go big or go home. I would say get rid of the meth kit when using the NO2, since the NO2 will cool the charge better than the meth kit. If you want to use the Meth when not using the Nitrous that's ok.

Personally I would do a 100 Wet shot when your wanting to "play". That's what I plan on doing if my Procharger don't make the power I want it to.

Well if I can keep the power I am making with the methanol and then add even more power only when i want to with the nitrous, why would I get rid of the methanol

Because it's redundant. If you want power all the time and an added boost at times, run a two stage nitrous system. Leave the first stage armed any time you want a little extra power, arm the second stage when you want the big hit. Or, get an electronic progressive system. Why have two separate systems if you only need one. Sell the meth kit to re-coup some of your costs.

Since I am new to the N20 stuff, isn't daily driving my car now with meth that kicks in at 5 lbs of boost and above, "safer" than running a constant wot activated shot of nitrous?

Nitrous isn't unsafe. People who don't know how to use it are. There's many different nitrous controllers on the market. You can activate the nitrous at 5 psi if you want.

Hmm never thought, of just running the nitrous instead of the meth. I just thought that if on the dyno I made 503whp with the methanol, if I through on a 100 shot simultaneously than I'd make 600hp. If I got rid of meth and just ran n20, I'd have to throw on a much Bigger shot to get to that same power level right. .. since technically I'd be running 91 Oct fuel, and not the meth which is like what... 110oct

My real question is this... Why not just swap the pulley on the SC and keep everything else the same? Why even bother with nitrous?

Already running the 2.6 pulley and the 34t cog.. there's really nothing else I can do the blower for power

Look into the Si impeller upgrade from Vortech. Advertised as a 10-15% increase in cfm. It's under $400.

Also here is an old thread I read on Vortech plus nitrous. https://my350z.com/forum/forced-indu...g-that-tq.html

Add the 27t cog on blower side, ati crank, and rev higher..

For nitrous setups, has anyone looked into the standalone fuel supply setups? I've seen Nitrous Outlet makes a pretty cool setup.

Meanz, how do u convert the serpentine side pulley to a cog when the rest of the pulleys on the system are ribbed

ogiehooker

Because you have 2 different belt systems on the blower...a smaller cog drive and a larger serpentine belt drive....I found that overspinning the blower drops the power off on the top end as you're just pumping hot air...check your pulleys and do a calculation to see how fast you are spinning your impeller and see what is stated as max....I also switched to the better impeller and noticed a little increase....

I just wonder if you aren't going to get a lot of belt slip when your N2O kicks in......I used to shred my small cog belts.....

yeah, i hear u. i am running the 2.6 pulley and the the 34t cog pulley but left the smaller cog pulley as stock. crank pulley is also stock so i am within the limits of the blower... just barely and make good power as is.. 503whp/435tq - but i do have some slip sometimes, and i even have the timmrod strut too- just that little 2.6 pulley...

ogiehooker

yup, an ATI crank balancer could help..it's a bit larger....

not needed. just make sur eyou have a big enough fuel pump and run a dry shot controlled by your EMS.

Since th car is built why only a 100 shot? progressive 200shot

Not a helpful response at all, but, my girlfriend was next to me when I read the title and I asked her "If I did meth while on a vortech, would you be made?". She got upset and asked me "why I even needed to ask something like that" then I showed her the post and she felt silly.

Apologies, I am extremely bored today.

hi folks..

My set up is a built block single turbo w considerable lag until i get into boost.. about 530whp on pump gas.. walb 400 single p8ump, cjm stage 0 rfs. stock rails for now ( will likely finally upgrade to cjm)
I hooked a deal with NX as well as with AEM ECU/electronics.. does anyone w expertice w either of those have suggestions as to how to run them together? Im looking for mostly a lag reducer bump that is boost variable.. dry/wet? NX controller? or can the AEM run it?
your thoughts?
Im on day one of my research.. i figure this will give me a nice performance bump while safely keeping NO2 away from fuel cut rpm areas.. all while displaying product for the manufacturers.
