im running turbo edit for engine management in a d16 engine full build
there is a rule for the nitrous thank you for any help

let the fuel do MOST of the work.start out advancing till you see pepper on the plugs"dedination" then bump up your fuel just a tad and you are good to go.there is not a set degree and if you go by manf. specs you will not reap the full benifit trust me.but if you want to know the genral rule of thumb for pulling timing it is 2 deg. per. 50 hp.

you would be surprized at how much timing you do NOT HAVE TO PULL.but everyone is under the assumption that you do.

i have always heard 2 for every 50 but it is different for every engine. that rule never worked for us.

 

if you have a built d and 150 shot why dont you just get it dyno tuned ? I would want to risk blolwing up my built motor

dyno will not take into account for the temp change.the best way to tune nitrous is soley by the jets.but be sure to look at every plug..or better yet shut the car down after a wot run and plull off and look at them."that is the best way"

 

on a 125 shot on our h22, 1.5 degrees seemed to be the best for us. We did a 3rd gear wot pull and pulled the plugs. The fel line was a bit higher, which a little bit richer on AF was good for me for a just in case thing, and the timing mark seemed to be perfect. It took about 5 or 6 pulls to the timing dialed in right.

 

is the 2 for every 50 apply for stock ecu's or everything. seems like with that much retard it wouldnt run as good.i am also considering the juice since im gonna pick up a ls complete motor for dirt cheap. so what do u think on a stock ecu and how much would u run

 

jetting is your friend. We run one step colder plugs gapped to .40" and timmed from there. But we got our advice from a guy that runs 8.20s in a 302 capri with a metric *** ton of nitrous

instead of changing jets just bump the fuel pressure up.the adj is your friend in nitrous tuning.yes retarding alot kills power"that is the holy grale of nitrous tuning " finding it.thats why i advance till i see pepper then bump the fuel pressure up just a tad,then look at my plugs"all of them" i keep doing this till i fined what i'm looking for.

 

when i see the pepper will that blow the motor till i get it dialed in. also what do u think the ls could hold i know it has lower compression so it will be a little more forgiving. are the zex systems any good the ones where u run the return line to the purple box. what systems do u recommend

this is some good advice

 

well there is a really big nitrous thread that me and cubish and phazechange all contributed to....but it is under cubish i think.


you want your plugs a lite brown.this is how i go about getting what i'm looking for.i start out w/some jets that get me close...but i like pushing the limits.when i start out with the jets.i will do a wot pull and shut her off when i am at wot.that will tell me what is going on inside.if it is dark black sut.then i am way to rich"depending on how rich if i change a jet or not".so if the plug is black then that means you need to either drop down a jet size on the fuel and then do another pull at wot and then shut her off.now say this time the plug is a dark brown instead of black "you know your on the right track".

then you can start advancing very little and check your plugs "every plug" after each wot pull.but a very nother "not sure that is a word"..important factor is CFP "CONSTANT FUEL PRESSURE".alot of guys and girls go out and throw 100-150 on a motor and wonder why it doesn't last.nitrous needs at least 40 psi cfp to see the magic start happing.but these guys and girls out here trying to spray like i said 100-150 on a walboro 255.....just isn't gonna cut it.sure you could bump up the fp to 80 or so psi and drown the **** out of your motor at idle and wonder why it is smoking in a week.


when you should do a dedicated line if your going 100 or more it is not that hard and your motor will thank you.NITROUS DOESN'T BLOW A MOTOR UP THE TUNER DOES.

 

more then 100 shot for a dedictaed line? Kinda low ain't it. I set my fuel pressure at 45 psi at WOT and set my jets for 48 psi and no2 jets for 950 psi. A little on the rich side but the motor pulls hard. Plus that msd retard box, the car runs advance off the bottle but once the soleniod completes the ground, the timing gets kicked back to safe nitrous setting.

no 100 is not low by anymeans and that is what n o s recommends and i have to say i agree w/them.yes muli steps come in handy.lets see you set your wot at 45 psi...maybe after a few pulls i can believe this.but how in the world do you set your jets @48 psi and the wot @45 "clarify this"

nos bp or nitrous bp they say to atomize best is 900....to me that is for amaturer's.when i spraid 400 on a b20 vtec try 1350.i capped off the safety valve and that bottole was very HOT....yes it was very stupid.but till this day
i don't know of any full int. ek hatch's or eg's running 6.94 @104 pulling 1.5 60's in an 1/8.

i also forgot to say the nitrous line was a little over 2 1/2 feet long....so imagine that HIT if you will.

 

what is dedicated line exactly. so your running the wet set up where u change the fuel and gas jets. i have a aem adjustable fpr so would that work for uping the fuel pressure.

sorry for the dumb ?'s i just dont want to blow up a good motor so im trying to do my homework. where can i find the nitrous thread you was mentioning

a dedicated line is a fuel line solely for the nitrous set up.i guess you could say it is a wet system.but it is 4 fogger nozzels instead of one.none of your questions are dumb.that is how we all learned by asking questions.how big do you plan on going...its not hard at all to run a dedicated line.there are several ways to do it.

1-get a fuel cell and mount your pump to it or close and run the lines.
2-sump your tank.

if you are spraying a 100 shot or more chances are you are using race gas.

 

so u run a direct port set up. i will probably spray a 100 shot. it will be in a gutted 88 crx so ill see how that goes. yeah ill mix probably 50/50 race gas when i spray it or should i run straight race gas. which nitrous kit have you had good sucess with?

 

i run 93 octane......no race gas.

have you tried race gas yet? youll be amazed at how much better it will run with nitrous.

 

I've read most the replies in this thread & some of you guys are pretty extreme when it comes to safety and/or giving some information that doesn't sound right to me.

But anywho, I was told that for every 50 shot you run 1-1.5 of retarded timing. I've gone through 3 bottles running a 150 wet NOS on 6 degrees of timing (44 psi fuel/255 Walbro/310cc inj) & it's still running strong.

you seem to be speaking from many many years of experience. oh wait you have only ran through 3 bottles!!! whats that like 15 runs down the eigth mile?

Most of my knowledge comes from a guy that runs 8.20s in a cpari with a 302 that he shifts at 8900(still a pushrod, go figure). He might know what he is talking about

 

So what about running two fuel systems in a DP?
C16 for nitrous and 93 for the injectors.

yes you can do that.....but sometimes it is easy to forget to check the fuel when you go out to have fun"it happens".i would just do from the tank up to the rail,plus you will be able to tell your gas level is.but to each his own.

well you tell us what info doesn't sound right........or share some info with us.i am always willing to learn.

yeah im always willing to learn thats why im asking all these guys with experience questions instead of questioning them like some people. hopefully there will be more good advice out of this thread.
