Should have given them some reagent grade ethanol to let them celebrate their victory...

I wish someone would post Dennis Hopper and his nitrous oxide mask ...

/... don't you fu(cking look at me...

I remember when I was going to school in Madison, you could get a big ass tank of nitrous no problem.

/meant there were lots of nitrous balloons at the Mifflin Street block party each year

hmmm what gas that's at least fairly safe would muck up an engine?

DrBenway: Life of the party, he was...

I can imagine he was. What's funny is that at one time people would inhale laughing gas just for the laughs. Then again they did the same with ether. And people think huffing is a recent development.

DrBenway: Sure -- back then, any little kid could buy all the airplane glue and spray paint he desired.



Yeah... and look where that got us.
Kid was a master of calculus, science, captain of the chess team, and later a leader of this new "computer" revolution.

Then, someone introduced him to sniffing glue, and his life entered a slow decline. About 7 years later, bam, he hits rock bottom and gets elected president.

One of them has a "Medical grade" sticker on the canister! 11 11tyt. As far as I can tell it's the only real differance apart from the extra price.

There is also the extra wanker cred in saying "I'm running medical grade nos which gives me a billionty more oxidations and 11 bilionty more horsepeowers than standard nos" so thats nice too

The Four Stages of Life

The inner child says,"Whippets at 7-11's expense."

The young corpsman in me says,"You're going in the brig you dumba$$."

The approaching middle-aged-crisis devil says,"Let's try that on my rice-burner rocket motorcycle. Note to self: Talk with mechanical engineering students Monday."

I have to wait 30 odd years for the cranky old man to say,"These kids today. I want my pudding with whipped cream. Did I ever tell you about 7-11...snore...dribble"

We all come full circle in life.

Kinda like HDMI cables. I can buy one for $2 at monoprice or a monster for $100 at Best Buy. I bet they are made by the same children working at the same factory in China.

Also FTA: Boy racers are thought to have been stealing pain relief gas from ambulance stations to use as 'rocket fuel' that boosts the performance of their cars. Is that "rocket fuel" horseshiat the Brit equivalent of what the Yank media does with big scary words like "automatic assault weapon" when someone uses any kind of firearm?

At least nitrous is actually likely to cause the floor to drop out of a chavved up renault clio.

A smart one would make his own. Oh wait, it's already done.

The difference between medical grade nitrous and anything else is that anything else has sulfur added to prevent people stealing it and huffing it. It's the reason these canisters have been stolen, I'd bet anything on it.

Nitrous is just a way of chemically spraying more oxygen into an engine, in a stable molecule. Liquid oxygen etc are too unstable and will create cylinder pressures way too high and you'll get what's called detonation, which will rapidly turn your engine into scrap. NOx actually cools things off when you spray it, it can cause your engine to run cooler than you'd expect if you set it up wrong.

Because it's a way of chemically adding oxygen, you need to add the equivalent amount of fuel also. There's a few different ways to go about this. You can spray just the nitrous into the engine, let the oxygen sensor read the amount of O2 in the exhaust, and the ecu will adjust the amount of fuel being fed into the engine. This is called a "dry system" because you're not spraying any fuel. Stock injectors can only give a little extra fuel though, figure maybe 10-15% more fuel than they'd normally be expected to spray before running out of capacity, so maybe 50hp worth of nitrous spray before you run out of injector capacity. Any more than that and you'll run the engine lean and break things.

A wet system runs a separate set of nitrous and fuel injectors, and an extra fuel pump as well. Lots of switches are recommended for safety, like if fuel pressure is too low etc...

Nobody would buy everything for a nitrous setup and then steal medical tanks, I would doubt the fitings would be the same, and it would be more expense than just going out and getting a nitrous tank filled.

Those tanks are pure huff fodder.

maidtina: At least nitrous is actually likely to cause the floor to drop out of a chavved up renault clio.

Get a car, not a golfcart that has a gasoline engine.

But then you wouldn't need nitrous.

/Yes, even turbochargers are as bad imho

I prefer the ether tanks. The pretty flash just before the big explosion, much more exciting if it's someone else's car, too.

They should just send out the "Entonox Canister Detector Van."

turbocharges aren't bad. if they are designed to work with the motor it's installed on(and vice versa).
my little VW Jetta works well for getting up to speed on a highway/interstate and not to bad for
passing cars.
but it's good practice to let your engine idle a bit after driving, to allow the turbo to spin down. they spin at 10,000rpm+ and still will be spinning after the motor is shut down and not providing oil to the bearings.

You're forgetting just how stupid these chavs are...
They won't know all the intricate details of how it works, they'll just put the tank in the back of the car next to the subwoofer and show all their friends their chavmobile!

I thought that little issue had been fixed with turbos manufactured in the past decade or so? I remember it being an issue back in the 80's and 90's

Had a tooth pulled yesterday with the assistance of nitrous, so I'm getting a kick...

the automotive stuff is blended with sulphur dioxide to give it a skunk smell and make you vomit if you huff it.

Close.

They spin at 100,000 rpm and the reason to let the car idle is to provide oil to the bearings to let them cool to a reasonable temperature to prevent the oil from 'coking' on the bearings.

Also, your VW turbocharger is likely water cooled, not oil cooled (the diesel K03 is oil cooled) so it likely doesn't apply to you. Do what is says in the owners manual though, German engineers are smarter than me.

'who's laughing now?'

Kreigenstein
oil cooled or water cooled, my point is still the same. let the turbo cool a bit before shutting down.

pretty universal advice.

The problem is that turbochargers are being used as the too-often way to run up engine power - without beefing up the engine block.

Has to be done...
Why so serious?

Most high performance cars have what is reffered to as a turbo timer. It keeps the motor running at idle for a set amount of time after any hard driving or long distances. Oil cooked into the crevices around bearings=all bad things. Take care of your turbo cars because for one I am jealous.

Actually the most common thing we see is people not beefing up their transmission and then wondering why it blew up when they spiking the engine's RPMs and blew everything to shiat.

This is correct. However keep in mind 90% of the turbos on the road are likely people just slapping one on their Camaro, Mustang, etc. Those guys tend not to wire in any kind of timer or the like and cook them off. Also these days most cars are programmed so they also run their cooling fans if needed, even after you pulled the key out and walked away.

Check dorms at the local college, you'll find the tanks there I bet...

Actually 99% of the turbos on the road are oem. Enthusiast installed turbos are statistically rare, even numbering in the tens of thousands, think of how many vw 1.8t engines have been made... or mitsubishis... or large diesel trucks....

Turbos actually spin at 200,000rpm or higher. Coking is caused by impurities in the oil baking into the bearing surfaces of the turbos when not cooled down, but most OEM cars don't have a turbo timer feater, being either water cooled, or having turbos that will last at least 50k, long enough for the warrantee to expire.

Can someone PLEASE post the NOS-energy-drink-in-his-bike's-tank forum thread?

Please?

Note (all) a good question is the diff between medical nos and the canisters you get for whip cream meant for restaurants. I'm led to believe that canisters have an oil applied to the inner surface for chemical stability with the metal, and that its not great to inhale as an aerosol compared to medical nos, which lacks this lining.

So I'm told.

DesertEagle: Can someone PLEASE post the NOS-energy-drink-in-his-bike's-tank forum thread?

[Shrug] OK (new window)... but it was prolly a troll.

can anyone tell me what type of turbo system is used in the Yamaha WR250X supermoto? It's not stock but a company is making them. Often performance upgrades on small displacement motors...say going from a 50cc to 88cc...you'll notice MUCH more power than say...going from a 650cc to 688cc. I'm trying to say I need a 88cc mini motard to stomp on all the scooter and moped trash in east Austin.

On the other hand...the Hayabusa (or Busca as black people like to say) often feature turbochargers as they make GREAT drag bikes. Besides that, they are pieces of garbage.

Just wondering since...well sure the faster you are on two wheels, the more stable you are...but still. Nitrous and turbo's on a bike? No thanks!!!

The problem is that turbochargers are being used as the too-often way to run up engine power - without beefing up the engine block.

The block (though I'll assume that you meant rods/pistons) doesn't *always* need to be 'beefed up' to add a turbo. Adequate fuel and tuning, as well as pulling timing when detonation is detected are MUCH more important. You can destroy your engine with a bad tune before adding boost.
