Alright, I'm a pretty much a noob when it comes to nitrous, but I am looking to go with a 50 shot dry kit. I'm wondering what type of gains I would get from it. I'm between 14.8-14.9 now, what would I be looking at while using the 50 shot?

 

i ran a 60 shot dry on a auto and did a consistent 14.5-14.6 at 96mph

 

Did you have any other mods or just the N2O?

 

im not sure but if you get a good systems and a bottle heater the 50 shot will work well.

 

I ran a 15.5 off the bottle and 13.8 on

 

well exhaust and intake at the time thats it

 

Damn with just a wet 50 shot? Was this before your other mods?

 

Also I plan on using my horn to spray the N20, being I don't want to spray in 1st. Of course I will also be using the WOT and a main power switch . I was just wondering if anyone else has used there horn to spray the nitrous. It will be hooked up to a relay so when I press it for the N20 the horn won't blow.

Any other ideas to use as a switch? I really don't any aftermarket switch on my steering wheel. I was thinking about making a switch down by where my left foot is while I'm not shifting...

 

I think jim will agree 1st is the best gear to spray if you can get traction. How do you think I got my 2.0 60' time I sprayed all through 1st. Jim would love to race guys that didn't want to spray in 1st and beat them all the time!!!

 

Traction is definitely a problem for me, depending on the surface. On most surfaces now, just punching it anywhere in first gear (5-25) I will spin just lightly all the way through the gear, so I know with a 50 shot it will be really bad.

 

Track is sticky ... You need better tires.

 

Works jest fine for my NX second stage....... four pushbuttons wired in parallel, mounted in a shallow electrical box, wired to the relay. WOT relay for the first stage, foot switch for the second stage. Keeps your eyes on the road that way.

13.61 ET 102 MPH

 

Use a WOT switch wired through a arming switch. Using the horn is super .

 

That sounds like a good idea. Do you happen to have a picture of the switches you used or maybe even a picture of how it looks all put together?

 

Also if I was just using a 50 shot I don't need to upgrade anything correct?

 

No I don't have any pictures, but got all the parts at Lowes hardware. The box is a plastic shallow low-voltage box. The cover is a plastic blank cover, and the four pushbuttons are normally-open switches with a 1/2 inch mounting hole. I put all four switches on the plate, wired them in parallel, mounted the box on the floor with velcro, and ran one wire to chassis(frame) ground and the other wire to the ground side of the power relay for the 2nd stage solenoid pair.

Since power to the relay is controlled by a WOT switch and bottle-heater circuit, the first stage comes on at WOT. By stepping on the floor box, the second stage can spray any time you want - usually after the auto shifts into 2nd gear. 50-shot on launch, 75-shot from the 2nd stage.

last PB run this season: 13.6 ET, 101.7 MPH

 

Thanks for the info. I will probably end up doing that. It might be a little pain at first because I have a 5-speed and use my left foot for the clutch, but I'll figure it out quickly.

 

Errr... You might have a problem making a floor switch work with a 5spd. I have an automatic w/VLSD and drop-resistor mod, which is ideal for the floor switch. I would have a problem shifting, using the clutch, and then hitting the floor switch again - and I've been driving manual-shifts for 48 years. Still drive a 5spd truck.

You would be better off with either a WOT switch or a WOT switch in series with a button of some type. That way, you could control the spray better - trouble is, you run out of body parts pretty quickly when shifting and spraying. I kinda like the horn switch idea - the button is on the steering wheel already. I don't recall anyone else using that button - some have rewired the cruise-control buttons for spray, but that is harder than the horn switch/relay idea to implement, IMHO. Make sure you can reach the horn button while driving with your left hand, though.

Besides, that way, you get to blow your horn on the drag strip....

 

Yeah I thought about using one of the cruise control buttons, but I would have to use my right hand and normally while racing I like to leave my hand on the shifter for most if not all of the race.

I can reach the horn with my left thumb from where I hold it (about 9 o'clock), but it does limit my grip on the wheel just a little. I have a feeling if I make it the horn button, I'll find myself on on-ramps, pressing the horn to get that boost I have come to expect or afraid to use honk when someone pulls into my lane for fear of taking off right into them.

 

so a 50 shot would give aboout 1.5seconds drop if sprayed in 1st, and all other gear

 

Bump for this post.

Using a wet 50 shot, and having a full exhaust, is there anything else required to running Nitrous reliably?

 

50 shot is the safest with minimal or no modding, if that helps.

 

Not mentioned in this thread is the fact that you can't spray while bouncing rev-limiter or with platinum plugs, so you should get a "rpm window switch" and 1-step colder copper plugs. Oh and I don't personally like the horn idea, I plan to mount a push-button switch around the wheel, right behind where my thumb would naturally be if I was driving agressively. on an auto it might be ok, but my car is also 5-speed.

 

I've also noticed that alot of people on here all agree that a short-ram intake and y-pipe are required, I am skeptical and would have no qualms spraying without either of them, but I would also be keeping a close eye on my plugs, and I personally will have both before spraying, I mean why not, it's cheap, beneficial, and i'd considered it a safe measure

 

Yeah same thing for me too, only I noticed that when I'm really hammering through the gears I like to have it around 10:30-11 o'clock to have more control over the tourqe-steer.


But only if you were honking your horn at wot, and if they tick you off in a situation like that, I'd see no problem with juicing them off the road!

 

I heard that by using 1 step colder copper plugs, performance is lost while not spraying. Is this true? If it is, is it alright to shoot a 50 without the copper plugs?

 

HAHA, I was refering to just being scared about using the horn just thinking it was going to happen, not really spraying. I wouldn't normaly drive around with the system ready to go. Using nitrous on the street is illegal anyway ...

 

SO NO ONE HAS ANSWER THE QUESTION. HOW...MUCH.. WILL... IT... HELP... ON .. THE... 1/4 MILE......?

not where to place the button.

 

POST #5
I ran a 15.5 off the bottle and 13.8 on
1.7 sec
With an Auto

 

I use 2 step colder gapped at 36 or so and my car runs great off the bottle!

 

I have 1-step colder and my car runs fine without the juice, worst case scenario they would get fouled quicker, but I have no problem taking my plugs out every so often to clean and re-gap them. Also, when you are juicing for the first time, you should hit that button only once or twice and then take your plugs out and make sure everything is cool, then juice a few more times and check them again, that way you will catch any detonation before it kills your motor.
To answer your question about not putting in colder plugs, that's cool if you want to stay at the stock heat range, just make sure they are copper plugs not the platinums that come stock in our cars.

 

Thanks. Can I pick them up at the local auto parts store? Also what exactly should I ask for?

 

Yeah just get denso or ngk copper plugs (I personally prefer staying with Japenese quality) The stock NGK plug has the number 5 in it, one heat range colder is 6. You should be able to get them anywhere, and there pretty cheap as well.

 

you wanna go with these copper i step colder plugs BKR6E-11, or ask for stock # 2756 at any autozone or strauss store.

 

Alright I think I'm going to go with the copper at the same heat range. With the way I drive I should have probably been running copper all along.

What do you guys think about the iridium plugs?

 

That's what I run... They run great!

 

I know copper plugs last about half of the platinum ones. What is the life span on the iridium plugs? Also what other advantages and disatvanges are there with the iridium plugs? I couldn't find to much information on them.

 

I'm getting really excited now about getting nitrous in my car. I'm Already running 14.602@ 96 mph. I should be in the low 13 with a good shot.

 

I've been running mine for a year or about 20K miles mostly off the bottle. Car is still kicking a$$... Need new axles now!
