Well I just got my nitrus on my car a s4 n/a and I was just wondering if anyone has ran a 100 or a 75 shot in thiers now I really need a anwser cause in a few days I am going to re-race a jetta 1.8t. I really dont need any badmouthing n20 I think it is all fair in the quest for horsepower so if I could just get a stright anwser I would like to know thank you

 

FIRST thing you need to do is open up a webster's....

second thing you need to do is ASK the actual question.

edit, i think i found the question. how many of us have ever ran nitrus?

jk dude

 

few questions to answer first:

- got a walbro or any higher pressure fuel pump in place?

- if u already have a pump, do u have a resistor pack to regulate the fuel pressure during low load and idle?

- is ur nitrous kit wet or dry?

 

ok my spelling isnt that great right now i know I am just in such a hurry to go try it out I just want to know if anyone has shot that much n2o in a s4 na before

 

no I dont have any fuel upgrades yet and it is a wet kit

 

ok...ur motor will go bye bye with a 75 and up hp shot without fuel upgrades.

i just noticed its for an S4............ur gonna need ignition retard of 1 degree/25hp.......so about 3-5 degrees for a 75-100hp shot. so that means either getting a standalone or 3 CDI boxes to tune ignition retard.

 

ok so could I run a 50 hp shot on it if I do a slight timing adj and will two deg. affect my normal driving

 

Midnight 7 , have you had any persona experience with the nitrous setup to be making those suggestions? Im not being a smartass, just asking. I think just for a 75 shot, and its a wet-kit, he should be "ok" with stock timing and everything. The only thing I would suggest is a larger pump, just in case. Id think even a stock T2 pump should surfice.

 

I am not sure about this but i think i read somewhere that you onlt need a timeing retard on 100 hp shot an above again i cant recall were i read this

 

my nitrous project is underway with the help of Sean Cathcart.....which is a 120 hp single stage wet system.

all my infomation came from him.

50 shot is fine......but changing ignition retard will affect ur normal driving. thats y u need "retard pills" that activate only during nitrous use......as Sean says, be modest about the power the car can handle.

you can always increase it as do your supporting mods, which hell of a lot better than a big shot blowing ur engine coz you wanted big power RIGHT NOW.

 

ok so I will test it at a 50 but no timing adj right

 

50 should be fine..........75 might still be ok..........but anything higher and ur risking detonation.

oh yeah, dont forget to upgrade fuel octane:

50 = 89
75 = 91
100 = 94
120 = ...cant remember what Sean said....hahahaha..

 

ok thank you I already knew about the fuel octane but I already pumped it full of premiun $35 ouch but again thank you
