nitrous on a 92 sc400?

[jibby]

First of all, Lowboost I was never offended at all and am open to these types of discussions that is how you learn new things. I was just inquiring on some of your statements only because I heard different and have experienced different. Just trying to put all the peices to the puzzle together, that is all. To your question on whether or not the IUZ.. can hold up with a 150hp wet shot of nos? Well my answer is if the nos system is installed properly and the car is stock with 230-250hp to begin with the answer would be yes with no problem... A modified 300hp sc400 running stock pistons and rods like my car may be a different story over the long haul... The pistons are the weak points in these engines then the rods, tranny etc....I have been pushing over the 400hp with the nos for the longest time, you say how is that so with a 100 shot, well with the heated bottles and I would estimate my average nos shot to be 125-150hp on average so you could say I a pressing the limits of this car for over a year with no problems. Keep in mind my sc400 was owned by an old doctor and dealer maintained up until the day I bought it with 92,000 original miles. I got the car two years ago and it now has 110,000 miles so it is a young one. I run sythetic oils and take great care of this car and it's transmission. Also I was running the stock sc430 tires on my LSD up until about two weeks ago so under heavy horsepower the rears broke loose often and easily, so just maybe because of all those factors I am living on the limits of my stock parts... Who knows and with each mod I do I get a little more nervous. These headers and fat rear tires will really put it to the test, so far so good....

As far as the bottle heating up and blowing that is not likely. I believe these bottles are pressure tested to hold 2000psi or more, I am not certain of that as fact but even heated they would be pressed to blow. I have probably had the bottle pressure to 1800psi the one time and 1500psi many times. Got real nervous on the 1800 or so psi run, but yes have the heater core wired into the ignition or a relay that will shut it off when the car is turned off and you will not have any problems as I have now done.

Having a fully charged 10 pound bottle in the trunk on a 100 degree + day sitting in the sun can heat the bottle pretty good too, but you just need to keep an eye on things. I have never heard of a bottle blowing up in any ones truck.... So no need to worry, I don't..... I certified scuba diver and use to dive all the time and I know you can pressurise the hell out of the scuba tanks and they are basically the same as the nos tanks....I would say there is almost no chance of blowing a nos tank....

This above photo is where a young man left his bottle heater on, it looks like a ford tempo so who knows how well installed the fittings and installed the kit. However it is proof it happens, and locally (redneckville) we have guys bring out a torch and heat their bottles up before racing, Im like these morons!

But anyways if you can find me a non traction control throttle body I'd give you my bottle Im selling, dont know if thats an even swap or what.

I plan on running SS headers, into 3 inch exhaust, short intake, short ratio 5 spd gear box, aluminum flywheel, spec stage 3 clutch, fuel system includes walbro fuel pump, 6an/8an fuel lines from tank to filter to nitrous system/fuel rails. Im going to start out with a 100 shot on the NA 1uzfe, see how it handles that.

So the over heated bottle blew up? I would think the top nozzle part of the bottle would come shooting off and send the bottle flying out the back or side of the car, (kinda like in the original movie MAD MAX) but an explosion where the metal casing rips apart I thought would be very unlikely. However, the gas tank is right there next to the bottle... Yeah, just be careful, that is very rare and should never ever happen...I am going to do a search to see what these bottles are rated at, and get back to you guys on this... Besides if you left the car and it blows because you forgot to wire the heater core correctly and then left the heater core on by mistake after leaving on a hot day then yes I would have to say you would be retarted. On the bright side of things in those rare situations atleast you won't be in the car and blow to pieces with the bottle and car.....

I will look into the throttle body for you, need to hit up the yards on Monday anyway for a few parts...Let you know...

 

[lowboost]

I know I did a google search and found the same picture I did years ago, so its not common, and most nitrous explosions are done on the motor in funny cars and such, not the bottle blowing up, however, ANYTHING IS POSSIBLE, especially when your dealing with cars.

Thanks for the Throttle body w/o Traction Control!

i myself am intending on fitting nitrous wet system.my previous motors fuel supply was td in just before the fuel rail 100 shot which worked fine.i would not recommend using iridum spark plugs with nitrous they dont handle the extra heat well. i use a copper core spark plug in a colder heat range more resistant.i live in new zealand last time i filled 10lb bottle was $140.00 not cheap here

In reguards to the Bottle blow up, there are a number of incidents where the Bottles have blown up like a bomb. I have heard that the NX and NOS kits have the worst bottles for this. The Zex bottle has a timer or temp sensor to shut down. Also a blow down valve would prevent this.

 

[jibby]

No way, nos bottles don't blow unless really stupid efforts are made to blow them up, like over heating, not watching the pressure gage. Can be just as unsafe as any other gas related part in your car it unattended too.... I talk to the nos pro's they tell me it is safer then gasoline and your gas tank.....that is why I am using it.. Dry systems are a little safer then wet as well...

Blow down valves are cheap insurance. I just got one a few weeks ago for $30.

Sorry I left something out. Not the bottle that is unsafe, it's the Heaters that do not have the safety measures that the Zex heaters have.

the other thing to watch is when refilling smaller, say 2 or 5 lb bottle off bigger bottle, when you make the bottle getting filled cold and then the bottle being used as the filling bottle hot, to try and squeeze as much NOS into the bottle as possible, they kind of go funny shapes when bought back up to temprature :blindfold

ALL NITROUS SYSTEMS HAVE A BOTTLE SAFETY FUSE.THIS LETS GO LIKE A BLOWER FUSE (WINDOW / BURST PANEL) HE WORST THAT CAN HAPPEN IS THE FUSE LETTING THE GAS FROM THE BOTTLE . I HAVE SEEN THIS HAPPEN IN AN OVERCHARGED BOTTLE

THE WORST THING THAT HAPPENED WAS THE PANNIC STOP BY THE DRIVER OF THE CAR THEN THE ICE AROUND THE BOOT LID ( GONE IN 60 SECONDS )
BEAR IN MIND THE BOTTLE HAD 975 PSI AT 5 DEGREES C (OUT OF THE STORAGE FRIDGE) IT WAS A 36 DEGREE DAY BOOT (trunk) TEMP PROBABLY ABOUT
45-50 DEGREES

NITROUS OXIDE AS A GAS IS AN ACCELLERANT IT DOES NOT BURN BY ITSELF
EVEN IF A BOTTLE WARMER WAS LEFT ON THERE IS NO FUEL TOO BURN AND HOW WOULD THE BOTTLE WARMER CAUSE IGNITION?

NO FIRE NO FUEL NO BOOM DA DA BOOM !

 

[jibby]

QCA - You are absolutely correct... It is a non-flamable dry chemical.... The Ka boom is from overheating. I have had my bottle peged at 1500psi+ and it was fine... My regular pressure is 1200psi most of the time... I may never push it to 1500psi+ again unless racing a monster and I need the added juice, just for safety reasons. Nos is safe.....period....

Yeah, I am sure you can find a couple of car engine fires or gas tank blow ups too if you search hard enough. If you really want to play it safe with nos and you live in place that has hot summers then don't get a bottle heater at all. Without a heating Element a nos bottle should never ever blow up.. Fill up pressure should be around 700psi on a 15lb nos bottle, just up the nos shot and forget about the heater core it's that simple.. That will make the nos system safe even for toddlers..:baby: The heating element is really not necessary with a nos system.

I guess you can say the heating action on a nos bottle is an option that should be used for people that will be very responsible with it...With that being said I probably should ditch my heating core..:dunce:

 

[graeme79]

After reading that article, and looking at all the site with relevant stuff on the who NX drama's, there seems to be one sticking point. The noodle left the bottle hearer on..... if he knew or didn't know the heater was on, it should leave the onus on him.

I'd like to see someone claim against a electrical appliance company for damages caused after someone left something switched on, and destroy something of value, see how much compensation you get.

Whilst it's easy to take sides, i think it comes down to facts and not interpretations. PLus seeing a origanal document as opposed to retyped transcript of a document, may eliviate some sceptasism.

anyhow, back on to the topic.

when running nitrous, following the INSTRUCTIONS from the kit manufacturer and you should have no worries. But if you do, they should have a Tech department to help you through these drama's.

About the heater situation :

1. We are human and we do make mistakes. I would rather have a bottle heater that shut's down if a mistake is made. A short or crossed wire could have caused the same problem.

2. I posted that so that others would know potentially how dangerous a 1500 lbs bottle could be.

3. I did research and knew about this Danger before I bought my Kit, and that is not the only incident that has happened like that. I have seen people heat bottles with a torche to warm them up, go figure.

4. A iron left on leaves you far less in Danger than getting inside a car with a bomb.

 

[lowboost]

yaeh, I knew all the precautions before I even got my kit, you have to respect anything that can kill you. machines are top of the list now days!

 

[jibby]

Man, I have had my nos for over a year, my heater core can now be turned on or off manually from inside the car and also I had wired it to where the heater core will power off when the ignition is shut off. I did that for safety precautions.

Bottom line is NOS is safe...or else it wouldn't be used and sold..it is as simple as that.. I for one was a little nervous in the beginning but after seeing how the system works and talking with all the nos pro's.. SO, Like I said before I believe it is safe even for toddlers....

However, I don't recommend heating your bottles to 1500lbs like I do, Im nuts like that. I am also a certified scuba diver and nos tanks are no different then scuba diving tanks and I know those 15lb scuba tanks can hold 2500lbs of pressure or more no problem...Now the only danger I can think of with a nos system is if you mount the nos bottle near your rear bumber and then you get rear ended by a semi truck going highway speeds. In that case the nos bottle may just blow.:yikes: Also with a wet system you need to tap into the fuel line which could possibly cause a dangerous gas/fuel leak, but you would probably smell it before the car blew up, either the fuel, nos, or smoke. I used only high pressure steel braided fuel lines on my dry system. A fuel leak is dangerous and a nos leak is not. So don't be afraid to nos it up fellas....It is rude and instant power waiting for you with just a button push away...uttahere

PS. Lowboost - I think maybe that guns are still on the top of the killing list, and machines maybe second..

 

[lowboost]

a gun is a tool/machine in my book lol, beats killing people with sling shots.
