was looking at the two aux inj's sitting in front of my intake, unplugged, doing nothing. with the right plumbing, could'nt they be used to spray nitrous ? seems like if you regulated the pressure, and used a switch to trigger the inj[s] you could make it work ? or am i over simplifying it ? don't know much about it. or how about methanol [with a pump of some sort ]? just dreaming, has anyone ever tried this ?

 

mAKES SENSE TO ME. I HAVE A WHIPPLE AND HAVE BEEN CHECKING OUT GETTING RID OF THE COMPUTER AND GOING TO THE MARINE 44LB OR SO INJECTORS. i WONDERED JUST LIKE YOU IF I COULD NOT USE THE WHIPPLE INJECTOR OPENINGS TO SPRAY METHANOL /WATER TO COOL THE INTAKE CHARGE. I THINK WE REALLY NEED THE INTERCOOLING.ALL THINGS ARE POSSIBLE WITH ENOUGH THOUGT AND A LITTLE LUCK. POST IF YOU HAVE ANY LUCK.

 

You could use it for Alc. injection with an aux tank and pump. Then you could crank the boost.

Then again i havent had a SC for awhile.

 

i figured you could run alcohol through them, but at such low boost would it be worth it ? how about low pressure nitrous ? i know you would have to run more pressure than your manifold pressure under boost. figured you could rig a button with voltage to the inj's and have a little extra power just for fun. just wanted too know if there was any reason it could'nt work before i start playing with it. i thought it would be sweet if you could weld a partition between the two injectors, use one line too inject methanol and one for nitrous. that way the meth. would help cool the charge and reduce preignition and the nitrous would give you a faster cleaner burn. or i suppose the whole thing could blow up. snake eater i see you have a dry shot, whats the difference between a nitrous nozzle and a fuel inj ? what else do you need beside a tank, lines, a regulator and a way to turn on/off the delivery orafice ? could this work ? if not , why not ? if so would this be considered a wet shot ? and how would you calculate flow, gas versus fluid. how fine is the line between oh yeah and oh sh-t.

 

Low pressure nitrous?? I dont see the point. If you want n2o just scrap the injectors and use their mounting location to insert some shark nozzles. Tring to rig up a fuel injector to spray nitrous is going to be way more trouble that it is worth IMO. Theoriticly it should work since an injector is basicly a solinoid anyway. But.. you have to some how rig the injector ot accept a 4an line from the nitrous that would not blow off or leak when you turn the bottle on. You would also have to figure out how to get extra fuel in for the nitrous. Would you use one inj for fuel and the other for n2o? Also how would you regulate the nitrous delivery. With a nozzle you use jets, with a inj it will just be open or closed. You would have to regulate it by pressure so you would then have to calculate flow rates at certian pressures to determine how much nitrous is being distributed. Just seems like a headache to me.

 

nitrous would be both a cooler and a power booster. scrap the injectors and just use the pretapped openings to mount the nitrous and gas mixers. or you could just plug the holes . what about a custom dual stage tune. use the big 44lb marine injectors and nos has a kit for the ls1 and maybe our trucks that slips a nitrous injector in underneath and in conjunction with the marine gas injectors. program the computer to add for both boost and the nos so the mixture is right. does it still intercool if you spray the cold nos right into the combustion chamber or would it be better to have it evaporate and cool in the intake manifold before it goes into the chamber . all just theories to ponder and perhaps experiment with. good luck with it . you should run it at carlsbad. nice cool air in the morning.every sat is grudge racing and one a month sun day bracket. their number 7607271171

 

the point is, rather the question is can the existing inj's be used for something that will increase power safely. seems most guys who have a whipple w/ the aux inj's eventually install larger injectors, so they are unused. if this can be done, it seems a cheap way to make power. as far as regulating the pressure, why can't you regulate the tank pressure like any other high pressure liquid gas [like co2] with a regulator ? i understand the inj is an on off valve, so if the line pressure is constant the flow should be constant. as far as additional fuel, thats another good question, can the pcm compensate via the o2 sensors ? my thought regarding lower amounts was that it would be less critical to exact fuel mixture, while still inceasing burn efficiency, giving more power. remember i know nothing about nitrous systems but i'm trying to learn, i'm not going to do anything stupid with my engine. but if i can set something reletively cheap and safe, i'm all over it. keep the comments coming, does anyone know if i can have a small co2 bottle filled with nitrous ?

 

I live in s orange county calif. here they will not fill a bottle with nos unless the bottle has been certified within the last five years. I have two nos bottles from my 88 chevy truck. used nos bottles are cheap. heck I will loan or sell you one cheap when you are ready for it. I may be working on something when I get the time.I would tend to modify an existing system of nos to work with the fittings from the whipple.with nos my personal experience is error on the side of a little to much gas cause you do not want to run lean with nos. too rich the power dies but nothing blows or melts.

 

when i say gas i mean the liquid stuff from the gas station .

 

gotcha, so in your experience, how much nitrous is needed to get a reasonable power gain [50 hp]. and is that amount enough to lean the system out to a dangerous level, and do you think the pcm can compensate via the o2 sensors ? if not it's seems like too much of a pain in the a$$. maybe more boost and alcohol is a better idea. guess i better get my tune straightened out first. whipple is supposed to be coming out with a new computer soon. still need that file '02 1500 hd 6.0 s.c edit file. anyone ? like to do it myself so i know what to mod when i up the boost.
