Nitrous, the power adder of fags
 

I did a search on nitrous equiped cars (no turbos), and found that there are very few nitrous cars out there.

I wanted to know how many of you are out there, and how fast did you go.

I have been addicted to nitrous for years, and am working on getting the nitrous back on my ride. It's not a ride without that oxide!:eek3dance

IMO the reason why theres not that many cars on spray is because of the fact, youll run out bottle before youll run out of boost!

He's had a 100 shot on his car for some time, and KNOWS his shit.

Nitrous is cool but turbo is WAY better:D

Use nitrous to spool your big turbo.

Hit that button once.

up tha BOOST!

For what it's worth Pat got sick of his nitrous setup. Went turbo. Couldn't be happier.

Heres vid of his nitrous setup:
YouTube - Miata MX5 100 Shot Direct Port

I really like my N/A set up. It is a different kind of look, sound, and ride. With nitrous, it is like you have 2 hot rods.

+100,000 miles per press


;p

Do you know if he ran it in at the track? I would love to know how fast he went.

I am sure I will get tired of my setup and eventually build a turbo car. I want to see how far I can go with my N/A.

There are some advantages to running nitrous. It is much easier to launch a nitrous car if equiped with slicks. When the light flashes, hit the button. It seems like it take more practice to get a good reaction time and good 60' time on a turbo car (at least 'grande' drag racing turbo set ups).

Nitrous is not so easy on radials however!

Did'nt get it:confused:

No idea on how fast it went. You'd have to ask him.

I do know that he accidentally pushed the button at idle once and blew his shit to kingdom come. That alone would keep me from going nitrous:eek5:

should be the same with a boosted car on slicks!

tree turns green, go, spool up, hall ass!

Or better yet, engage the launch control, build boost off the line, PROFIT:)
Might need a new rear end or transmission if you're on slicks though:giggle:

Yikes. I blew up a few myself. I have learned that people will warn you of the rules that you have to stick to when using nitrous. In the end, it seems you have to learn the hard way.

oh yeah i forgot about that neat little thing with certain engine management! :laugh:

fuck it! shit el buff!

That is the problem, you have to wait for spool up. Mean while, the other guy with much less power is at the 300' mark whoopin ass.

thats what launch control is for! i forgot about that cool little thing!

anyways im not one whos much for drag! im more into road racing and shit!

No worries! That is about all nitrous is good for really; drag racing. It will give you 60' times galore!

dragracing is cool and all dont get me wrong! it just doesn't last long enough! now if it was longer and they threw a couple lil S turns in there, then it would get exciting! hahaha

They have that too. Its called road racing:D

haha road racing is a crazy track that basically a circle, round and round you go! and the start line is the finish line.

i cant remember which need for speed it was buts pretty much there was a start and a finish line, with a couple of turns! the coarse would be bout a mile long! here the start and finish are totally different lines!

That's called mountain driving lol

:facepalm: erg! somtimes explaining things on a forum is so hard! haha

No, you don't have to wait. With launch control you can build as much boost as you want while standing still. When it's time to go, you let out the clutch and you go. And then, when you're shifting at redline, you are always in boost even with a big turbo.

I am not familiar with launch control or how it works. I will take your word for it.

I am aware that turbos are becoming the norm in drag racing, and it is pretty hard to be competitive unless you are huffing a turbo anymore. However, I have seen a lot of timeslips, and rode in cars with both power adder types. Nitrous cars 60' better, period. It is what makes them so much fun at the drag strip.

I know this is not miatanitrous.net, and I was hoping this would not be a nitrous versus turbo discussion. I simply want to know if there is anyone else out there on this forum, how fast they have gone, and what type of system they are running.

Am I the only one? :vash:

im pretty sure there are some people that are out there and on here who like the bottle!

:facepalm:

:giggle:

Is it really that horrible?

I think you need to burn your copy of The Fast and the Furious, yes. :laugh:

i wanted to say that earlier but didnt want to hurt anybodys feelings! :D

i used to run a 100 shot direct port on my 99

Ouch!:crx:

Really, please do share your infinite wisdom with us.

Thats good stuff.

I've never been a fan of the bottle. It might be fine for a drag car, but thats about the only use I see for it. Even then I would probably only use it to spool a turbo. Nitrous just sucks because its power you can only use when you press a button or when you hit a certain throttle %, and even then you can only use it for maybe 30 seconds total per refill, depending on bottle size of course. Too much trouble and not enough driving/usage ratio. Turbo is there all the time, ready for use whenever you want it, for more than 100,000 miles in most cases. Of course have some wrenches to tighten loosened nuts.

amen!

I run nitrous and boost. Hell my system is boost actuated when armed realy i like nitrous but the way i drive i would go through 3-4 tanks a week just going to work. At 70 bucks or more a tank i just cant afford to run the shit as my only power adder. So i have it on baord cause my snail cant realy blow much more air and the N20 gives me the lil extra.

I ran a 50 shot on top of my FM II back in '96 or so. It was fun and great for the instant spool. I was greedy and ran 16 psi and had a crappy tune with the link. Left part of a rod and 5 qts of oil in the left lane of Capitol Raceway on my first pass. I knew the motor would go eventually, but not on my first pass. I had 145K miles on the motor so it was no big deal, except for getting the car towed home. :(

16 psi + a 50 shot at 6500 rpm with knock = cylinder pressure through the roof and rod through the block.

Here are some of my best timeslips, when I had nitrous. I would like to see a turbo car with similar horsepower and trap speed have a 60' time as good as that.

The car had JR 4-2-1 header, JR N/A exhaust, centerforce clutch, aluminum flywheel, Mickey Thomson 20"x8"x14" on stock wheels, and a NOS dry kit, jetted with somewhere between 75-100hp. I can not recall exactly. The internals were bone stock.

Total costs for upgrades were less than $2800.00

I am not knocking turbos, definetly awesome. I want one. However, nitrous is not all bad.

^thts what im talkkin about

my car on a 100 shot was damn fast, i just got sick of it running out, so now im turbo,but i can tell that i was faser n the spray than i am on low boost

Having an empty bottle does suck. It is like getting caught with your pants down.

There's your answer right there. Sure you got more power out of your car from using the nitrous, but a turbo car with equal power and those tires would easily do the same.

A good 60ft is more about grip than anything. The reason that most people with a Miata have a slow 60ft is because they run their regular street tires at the track.

No worry about lag.

I saw this company demo'ing this and it's really weird. They are able to rev a car to any rpm and hit a button and the damn thing made 14psi. But it wasn't like a anti-lag or launch control...no popping or backfiring. If you closed your eyes, it would sound like someone had the car on a dyno and was brake-boosting it. I was talking to sone of the guys there and he couldn't explain to me anything as to how it works.."it was too much of a secret". :jerkit:
I mean, the guy couldn't even tell me how the box gets wired in. Kinda cool product for drag racing though. Nice smooth boost with no wear on the turbo from backfiring. I'm sure someone has video on YT of it working.

Quit speculating and prove it. Let's see some time slips. I did.

Was that a manual transmission car. It could have been a tranny brake which only works for cars with a torque converter

2800 hell my turbo system and nitrous still hasnt hit that cost yet. And i run a wet shot.

Sorry, I don't have any time slips as slow as yours.

That was for the entire build. Exhaust, clutch, tires, nitrous, EVERTHING.

Jay I do not want to start that, please. I was not here to prove that nitrous is better than turbos. I just pointed out some advantages.

If you want to compare the fastest time slips from cars that you and I have piloted, I can gladly show you a 9.20 ET at 146 mph. Not a miata, but I have been to the track a time or two.

Is nitrious better than turbo...no.

Is there an advantage in some situations for running it...maybe.

I'd like a 200whp miata for the track with an extra 50-75 on tap, so in that way its easier to flip a switch than load a new tune.

Miata2fast,
You've gotta be running higher FP or bigger injectors to run 100 dry shot. Which is it?

Jay's quote was for his Miata. He has some nice timeslips on MT ET streets.

Frank

well not the exhaust i had that already, and not tires as well i had those before and if we are talking those as part of the build my 250$ apeice wheels would count agianst me i mean the full turbo system and everything else bolted to the engine, walboro 255hp, the wet kit i scored off ebay, MS1, and the clutch. yeah I had the wheels and tires cuase i like to go fast anyway and didnt want to have to use my brakes when doing shit at supralegal speeds when hitting corners.

Please explain the statement that "nitrous cars 60ft better period" please. I feel that the 60ft is more a function of traction. How a car makes the power isn't relevant. Two cars making equal power, the one with the traction will be quicker if the driver doesn't screw it up. Take your car and my car, run them both down the track on the same tires they left the factory with and they will not put down a 60ft time anywhere near a car running a good set of tires.

IMO turbos are for your serious street/track car and nitrous is for when your in you stock dd and you need to teach some ricer a lesson every once in a while. BTW i'm all about corners but i can't pass up a chance to put a civic with an exhaust in its place

Much higher fuel preasure. A pretty crude way to get more fuel, but it worked. I think it was jetted closer to 75 actually.

I wrote this long explanation, and "poof" it disappeared.

The reason is that there is a difference in the torque delivery "promptness".

If there is no limitation in traction, the car that puts down the power sooner will get to the finish line sooner. Turbo cars come out softer, because there is a very slight delay in peak torque delivery. Even if the turbo car is under a load, and making boost, there is still a slight delay. In nitrous cars, there is no delay. It is instantaneous. When you are dealing with such a short distance, the slightest delay makes a big difference in the 60' time.

Now if there is a limitation in traction, the turbo car will have an advantage over the nitrous car. The power is soft and controlable on the turbo car. The nitrous car is too sudden and violent to allow for control.

As an added benefit, turbo cars are not as hard on transmissions, rearends, and axles as nitrous or N/A cars making the same power. Unfortunetly you pay the price by not getting that sexy super low 60' time.

Whether you are racing to 60' 660' or 1320', the car that makes the most power and gets that power down soonest, wins the race, assuming there is no limitations in traction. Jay, with the mph you are getting, you should easily get 1.6 or 1.5 second 60 times. The problem you are having is not in traction, but how soon you put the power down. Once you figure it out, you can easily go 10's in the quarter without making any more power. You have the mph.

I see where you are coming from with the putting down the power sooner and that's the goal for any setup regardless of the power adder. Using launch control that's not an issue with a turbo. It's immediate as soon as the clutch is released, same as a nitrous setup would be. I don't see where the delay that you speak of comes from. If you could help me understand this it would be appreciated.

I still feel it's all about traction when we are talking about the drag strip. I would love to let someone with an entry level setup using street tires borrow my tires and make a few passes just to compare.

Now the method of launching and actual car setup would make for an interesting discussion. Whether using a turbo, nitrous or even a supercharger would all probably be a bit different in the style of launch.

I bought patsmx5's nitrous kit and ran a 130hp jets on a stock 1.8L... i had a stock clutch so that didn't hold very well:laugh: so i went down to 80hp jets which was fun and all but the bottle emptied to quickly... now i have a turbo at 10psi which is much better for street use.

Just a quick OT, whatever happened to pat?
