WHAT SIZE JETS SHOULD I USE+++ spark plugs?
I have a N.O.S. Dry-kit. I have on there .40 jet spray nozzle and .34 on the vacuum. Is this good or weak.
- I just took off the factory down pipe and replaced it w/ down pipe with resistor
- What are some of your setups with nitrous?
- Should I go one step colder with the plugs, I haven't changed them yet and I have 53,000 on the car?

.040 should be around 90hp, but ive never ran a jet for vac???
my edelbrock kit has a .042 for a 90shot, and a .050 for a 125 and its dry, and ill be posting a/f's and dyno #'s within a few days.
good luck hope this info helps a little

the dry kits actually add more fuel by raising the fuel pressure using the fuel pressure regulator, well that is not going to work on a returnless fuel system, that .40 jet is going to be about a 80-90 shot and running that dry on our cars is not going to be a good thing,
its really not that expensive to get a fuel solenoid, a tap into the fuel line, a hose over to the nozzle and another nozzle, better safe than sorry in this case
i am running a .53 which should be around a 130-135 shot with a fuel jet of .28, my wideband shows perfect 12.3 to 11.9 s across the whole rpms

but it looks like your nozzle is after the mass air sensor put it before. we dont have a system to raise the fuel press so if u trick the mass with the nos the computer will do it for you.

the vacuum line that you have hooked up will not raise the fuel pressure like it is supposed to on a return fuel system car, you either A need to add a wet kit to it or B need to run a smaller jet size so it will be safer with no fuel being added
i know you said it is expensive to add the fuel system, i would guess right under $200 dollars, and you are worried about tapping into the fuel line....
think about if you send a piston through your side of your block how much that is going to cost ya, > 2000
nitrous is a really safe reliable way of making your car faster, when installed and used properly so just be careful cause these cars are very expensive to fix when they break

where can I get one of those adapters, is it hard to put in b/c 1) I dont wont to blow somthing and 2) I don't really like messing with the fuel line stuff
oh and Im not getting any detanation after one shot through first and second
so my safest thing right now would be put a smaller jet likw .34 or .36 before the MAF

well actually audible, if you chill the mass with the nos it will trick the computer into thinking it is colder outside so it will supply more fuel to the denser air. and due to the more cfm going through it cuz of the pressure of the nos the computer will callibrate. so by doing it that way you have 2 sensors working with u the mass and the o2. if u put the nossel after the mass all u have is the o2, it will still work the o2 will see u are going lean and correct but it is safer to have the mass pick it up too. the guy wanted to run a small shot and if he does it this way it will be fine. of course if u want more a wet kit is the way to go. as far as cost goes it seems odd that someone can afford a 30+k car and insurance but not a couple bux for a wet kit.

So could I put the nozzle infront of the MAF with the same shot? And would this effect my MAF senser with the extreme cold.
BTW. moneys is tight yes thats why, G , house , Insurance on both

if money is tight then go with a wet kit. you'll save thousands on a new motor. its not worth the hassle and you need to reprogram the cpu to dump more fuel. it'll end up costing you about the same as a wet kit to be honest.
why would you guys put the spray nozzle before the maf? thats a very bad idea. first of all, its supposed to be within 6 inches of the plenum inlet. (cant think of the right term for it right now).
1. the extreme cold over time can and will damage the maf. i was bored once and i decided to empty out the leftover nitrous on a tshirt. lets just say i broke the shirt when it was all said and done.
2. the longer nitrous stays in the intake tube, the less potent it will be when it reaches the plenum. nitrous will warm up fairly quickly in a hot engine bay. warm nitrous means a smaller oxygen charge. it will lose its effectiveness, could cause you to run rich and you run the risk of fuel puddling. we all know what happens when fuel puddles. all this because you wanted the maf to trick the computer into dumping a little more fuel into the engine? not worth it imo. the whole point of nitrous to keep it as a stand alone system. you dont want to interfere with the ecu unless you absolutely have to.
good luck.

i guess no one listens in this forum. i feel that i have explained y to put it before the maf. but then i have only had nos on about 8 cars of mine what do i know? hell call holley direct and ask them. nos is owned by holley so u can call them and ask for nos tech.
