Hey guys, who in here is running my similar mods with a wet shot of nitrous? im looking into purchasing a full set up for nitrous from dynotune here in the next month. including the kit with 10lb bottle, rpm/tps switch,bottle pressure gauge, pressure controlled warmer,remote bottle opener,and purge kit...how is the nitrous working with you guys? im looking at a 50 shot max, but most likely a 35 just to be safe...posting pics would be cool too!!!

welcome to the nitrous realm...we have similar mods... from my experience, ive learned that you need a proper flowing exhaust to run the nitrous nicely...i just clogged my stock cat from running too rich with my meth & nitrous together...gotta tone down the meth mix lol....no direct correlation to having nitrous...but im sure it was "the icing on the cake"

but seeing your mod list, you should be fine as long as you take all the neccessary precautions before you spray (ie, knowing bottle pressure, keeping an eye on afr's, etc...)

good luck, and im sure ull be happy with the results once complete

A 50 shot should be fine. I'm not sure with a 2.7/2.8, but I have heard of multiple people running stage 2 type setups and running 50shots all day long with no problems. And x2 on the at LEAST 2.5" catback setup w/hi flow cat (preferably no cat if you can get away with it)

yea i know alot of stage 2s running the 50 as well. but im trying to shoot for 320-350whp....and for under a $1000 nitrous is the way to go cuz i cant afford the tvs (im only 18 years old and living on my own!!!) haha i know i would need to purchase a wideband to monitor afr, or dynotune sales this neat afr reader that if the afr gets to out of whack it automatically shuts down the nitrous to prevent detonation....so im considering that. um i have the zzp downpipe with highflow cat...and im about to get a new header. would you guys think itd be worth it to upgrade to a 3in exhaust with no cat downpipe? keep in mind my downpipe is 3inches but has 2.5in bolt on flanges...

my header is whats restrictive...i have the gm extrude honed manifold. i have a buddy sell;ing hte cobalt addiction v1 header to 100 bucks, i might pick that up. but if yall think i should go 3'' then i might not buy it

oh and i also will be custom dyno tuned in the next week to two weeks....so its gunna take me probably a month or so to piece everything together...longer if i have to buy all new exhaust components.

what kind of HP and 1/4 mile times will a car with those mods put down?

3" is what you want if you are looking for that kind of power

with 60's and a 2.7-2.8 pulley you are running a high enough output to where a 3" may be beneficial...especially with nitrous, go for the midlength header, dp combo from zzp....and get the 1 3/4 primaries....plus a midlength header an dp give you a better more even powerband and spread the torque out more than a shorty header does.

including the kit with 10lb bottle, rpm/tps switch,bottle pressure gauge, pressure controlled warmer,remote bottle opener,and purge kit...

Props for building a proper N2O system, with all the safety stuff.

I'd highly suggest adding this to your list as well. -> ARF Switch (http://www.dynotunenitrous.com/store/scripts/prodView.asp?idproduct=67)
Tie it in to one of the outputs from a wideband, and it should keep you safe.

yea thats what i was taling about in my last post. do you guys kmnow if i could simply cut my cat out and weld in a 3inch straight pipe, then cut the 2.5in bolt in connector to my ehxuast, weld in a 3inch pipe all the way back and cut my muffler off my megan exhaust and weld into the 3inch pipe?? itd be a hell of alot cheaper...

Uhm... sure... if it will pass inspections wherever you are at. And... it will sound like shit most likely.... Buuutt I don't see why not

well id expect in 3 inch exhaust with no cat to sound like shit, haha. but if it helps my performance and is worth the money then i dont give a shit...its still guna sound better then any honda!!! haa

kelby.. why is it when i get my nitrous almost on and working you go and want to buy a full kit justl like i did? its not fair:( i wanted to be the only balt that was spraying around here.




just kidding man, place the order soon so we can get it on your balt. and maybe by then ill have had mine up and running and will be able to work with yours better. or i might blow mine up and have you send all your stuff back hahaha. either way lets do it!

hahahaa...oh well. its worth a try. i think id do just the 35 shot a few times and see how that works out. and i have to order everything peice by peice...i cant just do $1000 up front right now. But im working on a midlength 1.75" primaries header and a 3" catless downpipe now to support all this stuff. my car is guna sound like shit, but like i said before, it still shouldnt be like no damn honda! ha

it'll sound like raspy air hahaha i cant wait. your car is already toooo damn loud. im sure you'll pick up a noise ticket or two after all that. riddin in it gives me a headache....

lol, itll sound just as bad as a honda...trust me man...but its ur call...i suggest at least a resonator in its place....little to no restriction while keeping the rasp down a tad.

good idea. def something to think about kwest...

So how does the motor take to n2o. How would a stage 3 or stage 4 do with a 50 shot?

Do you have HPtuners? With stock timing I think you can do a 75 shot with a 2.8 inch pulley.

Thats gets you about 307 whp.

You are going to need to upgrade some pistons before you move to more nitrous than that.

we have stg 4's?:eek:

lol, so far so good with the spray

hmm...how long and how often do you spray? and im most likely going to do just the 35 shot, but OCCASIONALLY (thats the plans atleast) a 50 shot...im just to nervous! haha the cars a daily driver and im only 18 so Im limited to what i can afford at one time!!! haha

im very conservative with the spray... its $9/lb over here

...altho, yesterday when i filled up...the manager only charged me 30 bucks...cool guy

wow thats insane. its like 4/gallon here i believe...well im going to start peicing it together. im just trying to determine if i should drop down to a 2.7 or not and run the 50 shot. any opinions?

my opinion is to stick w/ a 2.8...but its ur choice...even at 2.8, i get a lil worried, to be honest...

meh, one day it will be turbo'd...then i can enjoy my car w/ less worrying about heat and overspinning a blower.

not to mention that im the type that gets very paranoid...so the rock in charger sound sometimes appears to be getting louder...its just my nature...cant wait to not worry about that, either ;)

rock in a charger???? haha specify please.

he needs to replace the coupler...cheap and easy fix

anyone got pics of the lsj nitrous setup ..pref. the dynotune kit :)

well is the header a must because i dont have one. i have a 3'' catback i got my zex kit sitting right next to me. Downpipe is not problem i could make one in like an hour if i really wanted too. on im putting a 75 shot on it btw.

stage2cobaltss - I have a full dynotune nitrous setup that I will be putting pics up of soon. Remote bottle opener, purge, automatic bottle heater, pressure gauge, nitrous activation, tps, lean/rich afr fuel shut off, all that jazz. I will get pics up as soon as im feeling a little bit better.

hows the car running with your n20 setup? you spray often?

haha i just posted in another thread about someone wanting nitrous..

Now granted I'm still on a stock motor so to speak (Pulley, injectors,tune, etc) but i've run a 75 shot last summer while racing. that totals to be about 1 to 2 trips to the strip a month. Yes i do plan on doing pistons this summer, their the only thing im truely worrieda bout. I also progressively went from a 50 shot in the beginning for the first few trips then i got ballsy and did the 75 shot for the rest of the time... not that it matters to "Progressively" up the amount but like yourself i was alilttle nervous at first but my brother has run nitrous for many years with all different kinds of set ups so he was there to guide me along my way
